A Talented Team Meets the Needs of New Children’s Hospital

Roofing is a rewarding job; it is worthwhile to know someone or something is safer thanks to your work and craftsmanship. Every day across North America, roofing systems are helping keep people, possessions and businesses safe. In 2017, a mission to help heal the children of Louisiana began at the groundbreaking ceremony for Our Lady of the Lake Children’s Hospital.

When the hospital opens in the fall of 2019, it will join a statewide network providing families greater access to physicians trained to care for children in more than 25 specialties. The new hospital will also join the Children’s Miracle Network, a nonprofit group that relies on donations, community support and fundraising partners. Comprised of 170 hospitals in the United States and Canada, the group treats more than 22,000 children a day, and 1 in 10 children in North America are treated by the network each year.

To help protect such an important building, a high-quality roofing system was mandatory. So, the local professionals from Roofing Solutions LLC were enlisted to identify a roofing system that matched the building owner’s requirements: durability, resilience and low maintenance.

Designing the Roofing System

“We were invited to participate in the designing process, and it quickly became more than just a project,” says Tupac de la Cruz, the founder and operations manager of Roofing Solutions LLC. “Due to the nature of the building, we needed roofing materials that possessed exceptional strength and a low-maintenance factor to avoid possibly loud disturbances from upkeep.”

The system also needed to support extensive foot traffic and aesthetic customizations, according to de la Cruz. Portions of the roof were colored and decorated to reflect the diverse ecosystem of the Louisiana bayou, helping make the view more comforting. This matched internal design elements too, where each floor is designed to spotlight vibrant ecosystems from throughout Louisiana — including woodlands, marshes and coasts — along with animals indigenous to each region.

“The lower section’s roof is visible from many of the rooms above. By decorating it, we hoped to create a fun surface that would provide the children a greater sense of ease and calm,” notes de la Cruz. “From a professional standpoint, ‘resilient’ became a distinct qualification in the material selection process.”

After conversing with the building owner and HKS Architects, Roofing Solutions LLC decided to install 924,000 square feet of styrene-butadiene-styrene (SBS) modified bitumen for its proven performance, durability, lifecycle value, resilience and low maintenance.

“When we compared the options, modified bitumen was the best choice for the type of application and the performance the owner was looking for,” says Lauren Reynolds, the business development manager for Roofing Solutions LLC. “Modified bitumen has stood the test of time and proven its capabilities — especially in terms of strength and function — so the decision was made to install an asphalt roofing system.”

Installing the Membranes

The roof system was manufactured by SOPREMA. SOPRA-ISO+ polyisocyanurate foam insulation and a 1/4-inch SOPRABOARD cover board were mechanically fastened to the prepared structural steel deck. The insulation’s closed cell structure is bonded to inorganic, coated glass mat facers on the top and underside. The semi-rigid cover board is composed of a mineral-fortified, asphaltic core formed between two fiberglass reinforcing piles designed to enhance the strength and impact resistance of the system and help protect the insulation below.

For the base ply of this multi-ply system, a layer of ELASTOPHENE FLAM 2.2 SBS-modified bitumen was heat welded to the cover board. The base membrane is reinforced with a high-quality, random glass fiber mat and is surfaced with polyolefin burn-off film to optimize welding. The asphaltic cap sheet used was ELASTOPHENE FLAM LS FR GR, a fire-retardant membrane that’s surfaced with ceramic coated granules.

For the flashings, SOPRALENE FLAM 180 was used due to its dimensionally stable, non-woven polyester mat that adds toughness and durability. The flashing cap sheet selected, SOPRALAST 50 TV ALU, incorporates a high strength glass scrim and the topside is surfaced with a reflective aluminum foil, which is designed to improve UV resistance.

“We felt an asphalt roofing installation would provide the best long-term value and reliability,” de la Cruz says. “We worked closely with the architect and general contractor to ensure a proper application of these high-quality materials.”

While Our Lady of the Lake Children’s Hospital’s roof is complete, the entire project will not be finished until the fall. When the hospital officially opens, it will begin helping children from across the state heal.

Recognized for Asphalt Roofing Excellence

For its displays of craftsmanship, Roofing Solutions LLC was honored at the International Roofing Expo by the Asphalt Roofing Manufacturers Association (ARMA) through its Excellence in Asphalt Roofing awards program. The free-to-enter program recognizes outstanding steep and low-slope asphalt roofing projects and contractors from across North America.

“Excellence in Asphalt Roofing allows us to recognize contractors who use asphalt roofing systems to make a difference in their communities,” says ARMA’s Executive Vice President Reed Hitchcock. “Asphalt roofing’s aesthetics, durability and reliability provide peace of mind to building and homeowners alike. We are truly proud that asphalt roofing played an important role in establishing Our Lady of the Lake Children’s Hospital.”

Re-Roofing a Busy Hospital Poses Logistical Challenges

At Holmes Regional Medical Center, Advanced Roofing replaced 32,000 square feet of roofing on four different levels. Photos: Smith Aerial Photos

When leaks on the existing roof on the Holmes Regional Medical Center in Melbourne, Florida, became too much to bear, the need for a new roof on four levels of the building was obvious. But so were the numerous difficulties posed by removing and replacing the roof on an active hospital. To make matters more complicated, the areas affected were directly over the hospital’s main entrance and the neonatal intensive care unit (NICU), which cares for premature infants.

It would take a talented team of roofing professionals using the right products to install a durable roof system without disrupting patient care. Advanced Roofing Inc. was up to the challenge.

Advanced Roofing is a full-service commercial roofing contractor based in Florida. The company’s corporate headquarters is in Fort Lauderdale, with offices in Sanford, Tampa, Miami, Jupiter, Fort Myers and Jacksonville. According to Jason Carruth, branch manager of the Sanford location, the company installs almost every type of low-slope and steep-slope roof system. “We do production, service, maintenance — anything to do with commercial roofing,” he says. “Our specialty is re-roofing occupied buildings.”

For Holmes Regional Medical Center, a two-ply modified system with a reflective coating from Tremco was specified. This was an ideal fit for the re-roofing application at the hospital, notes Carruth, as it was a cold-applied system with low VOCs. “As a certified Tremco applicator, we were invited to bid on the project, and we were successful with the contract,” says Carruth.

High Degree of Difficulty

The project involved the complete tear-off and replacement of the roofs on the four lowest levels of the hospital, totaling approximately 32,000 square feet. These included two of the most sensitive areas on the building. “We did the whole section over the main entrance where everyone drops people off,” notes Carruth. “Another section was directly over the NICU center. We did the staging and handled personnel coming in and out on four roof levels over that area. The entire roof section also surrounds an open-air atrium below, so we had to roof around not only the main entrance, but an atrium as well.”

Safety was the top priority, both on the roof and on the ground. “We had to have full-time supervision on the ground,” Carruth says. “We had ground safety monitors that worked for us, and they had to coordinate traffic at the drive-through and the turnaround, as well as the pedestrian walkway, which was right at the edge of our staging area.”

The site posed numerous challenges, as the lone staging area was limited and the schedule was subject to change at a moment’s notice due to emergency surgeries. “Work over the NICU unit was a little more involved due to the fact that we were almost continually on call,” Carruth explains. “On days we were able to work, we had to be ready to stop if there was anything critical going on.”

Work began in the areas with the most problems. “We started in different sections based on the priorities of the hospital,” Carruth notes. “We initially focused on the areas where the leaks were the worst.”

After the problem areas were fixed, work proceeded in sections, working from the back to the front to minimize traffic on completed areas. The process involved tearing off the existing built-up roof down to the concrete deck and installing a temporary roof to keep everything watertight. Then tapered insulation was applied in cold adhesive, followed by a cover board and the two-ply smooth modified system. The last step was the application of the Alpha-Guard MT coating, which was set in a polyester mat.

Logistics, loading and disposal of debris was a complicated process, as crews could only load the roof at one point accessible to a telehandler — a 10K Lull. This meant much of the material had to be moved a long way across the roof. “We had to haul all of the material and all of the debris from the old roofs across a level, down a level, and up a level to one spot,” Carruth explains. “Mobilization was a little bit difficult on it because we were only allocated one staging area.”

Tear-Off and Installation

Advanced used a 10-man crew on the project, doing most of the demolition work at night and installation work during the day. The fall protection plan included Raptor tie-off carts and anchor points at higher levels of the building.

Mechanical roof cutters were used to tear off the existing built-up roof. In some sections, lightweight concrete also had to be removed. Debris was placed in a custom-fabricated trash box with a lid that had special forks for use with the telehandler. “We cut the old roof into small sections and just used hard elbow grease to pop them off the bottom,” Carruth says. “We utilized a Lull and a trash box to dispose of the that debris, driving it over to the dumpster, which was in the parking lot.”

After the temporary roof was installed, tapered insulation was set in a low-rise foam adhesive. This was topped with half-inch Securock cover board and the modified sheets. The two-ply Tremco system consisted of a PowerPly HD base sheet and Composite Ply HT top sheet, both set in PowerPly adhesive. Before the coating was applied, all of the edge metal and trim were installed. “We put all of flashings in, put all of the sheet metal on, we put the counterflashing in,” notes Carruth. “All metals were installed on this project were stainless steel, as it was in Melbourne and pretty close to the coast.”

The Alpha-Guard MT base coat and Alpha-Guard MT top coat were set in Permafab polyester fabric. The coating was applied using a squeegee.

The system supplies the benefits of solar reflectance, which include lowering the roof temperature and minimizing utility costs, but the roofs also had to be aesthetically pleasing. “There are patient rooms that look down in this roof, so that’s why we went with the light gray coating, which still supplies the necessary SRI [Solar Reflectance Index] value,” Carruth points out.

Minimizing Disruptions

The work areas also necessitated other considerations for patients and staff. “We had guest rooms where we had to hang tarps up so people couldn’t see us working at the time,” notes Carruth. “There were passive air louvers that we had to cover to keep debris from the tear-off from getting inside the building. We also had to put charcoal filters in all of the air intakes.”

The work schedule could change on a moment’s notice, so the roofing crews kept in almost constant contact with facility managers. “We’d provide them with a weekly schedule and every day we let them know where we would be working and what we’d be doing. If anything changed, we’d hear about it from their facility people and adjust on the fly.”

The project was completed on time, despite numerous weather delays and interruptions because of surgeries in the NICU. “The communication between the manufacturer’s rep, the owners and ourselves was excellent,” Carruth says. “Pre-planning is everything. When the key players on a job are all on the same page, that’s when a project ends up being successful.”

Success on this project meant protecting the patients and pleasing the owner with a top-quality system. The roof system was designed for high-priority, high-sensitivity projects, and there are few areas that are more sensitive than a neonatal intensive care unit. But these types of projects are familiar territory for Advanced Roofing.

“This is what we do. We re-roof occupied buildings,” Carruth says. “Not only are we putting on a roof system, we’re dealing with customers, we’re watching the weather forecast and making sure the roof is always watertight. The experience Advanced has roofing occupied building is why Tremco and Holmes selected us for the project. We know how to handle those situations and keep the roofs watertight on a daily basis.”

Contractor Has the Right Prescription for Medical Office Building

The Pflugerville Parkway Medical Office Building features a metal roof, a TPO roof, metal wall panels, soffit, fascia, gutters and downspouts. The new construction project was perfect for Texas Traditions Roofing, which prides itself on its versatility and quality craftsmanship.

Headquartered in Georgetown, Texas, the company handles a variety of commercial and residential work. “Residentially we do replacements and custom home new construction,” says Michael Pickel, estimator, Texas Traditions. “On the commercial side, we do mostly new construction, but we also do commercial repair and replacement as well.”

Pickel was the estimator on the project, but he feels the term “estimate” doesn’t begin to cover what his job entails. “We want to be the experts and provide all of the information for the general contractor, rather than just throwing an estimate at them,” he says. “We take that responsibility very seriously, whether it’s residential or commercial. We don’t necessarily like the word ‘estimate’ because it sounds like you’re guessing and just hoping it’s right. We understand that commercial new construction involves an estimate, but what we try to do is just be very specific and clearly define what we’re going to be doing, how we’re going to be doing it, and what the manufacturer and what the NRCA recommends us to do. That way nothing is incorrect, it’s not going to leak, obviously, and you have the backing of the manufacturer because it was installed properly.”

Multiple Systems

The scopes of work included two sections of metal roofing — a peaked section in the middle of the main roof and a shed roof off to one side of the building. A TPO roof system was applied over the main roof on either side of the metal roof in the center. “We started with the metal roofing panels on the top first, and then worked our way down to the lower section on the side,” Pickel notes. “Shortly after that, we came back and installed the TPO roof. It was pretty open, so it was fairly easy to put that down.”

The low-slope roof sections were covered with a 60-mil TPO system manufactured by GAF. Photos: Texas Traditions Roofing

The metal roof system manufactured by Sheffield Metals features 1.5-inch Snaplock 450 Panels in Ash Grey. Approximately 4,000 square feet of roof panels were installed over two layers of 2.2-inch polyiso insulation, which was mechanically attached. The underlayment used was Viking Armor from Viking Barriers.

The 6,000-square-foot low-slope roof was topped with a 60-mil TPO system manufactured by GAF. First, two layers of 2.2-inch polysio were mechanically attached to reach R-25. A tapered insulation system was then fully adhered across the entire roof to ensure proper drainage.

The safety plan utilized a Raptor safety cart, which was lifted to the roof with a SkyTrak. “The Raptor system was either on the left or right side of the roof, depending what side we were working on,” Pickel says. “Any time workers were on the roof, they were tied off.”

After the roofs were completed, the focus shifted to the wall panels. Berridge Vee Panels in Charcoal Grey were installed using a man lift. “We put Z-purlins down horizontally over the vapor barrier,” notes Pickel. “Then we installed the 1-inch, four-by-four mineral wool insulation, and attached our panels over that.”

Metal crews also installed 11-inch fascia across the entire edge of the roof, including both the metal and TPO sections. “There are some tricks involved with that because it was a fully tapered TPO system, so your height differences can vary,” Pickel explains. “Making sure the fascia wrapped smooth and properly, and was the proper height, was a little tricky.”

Gutters were not originally specified, but they were added at the suggestion of Texas Traditions. “We talked to the G.C. about talking to the owner because we felt they were going to want gutters,” Pickel recalls. “They came back to us and said they wanted gutters, so we issued a change order for it.”

The company installed 6-inch box gutters and four-by-four downspouts matching the metal roof.

A Challenging Schedule

The jobsite was relatively open, accessible and easy to navigate, so some typical problems that can crop up with new construction projects weren’t a big issue. The HVAC units were installed on a pad within a fenced-in area on the ground, minimizing roof penetrations as well as foot traffic on the roof. Crews were able to focus on doing the job right — and doing it safely. “Installation-wise, it wasn’t too tricky,” Pickel notes. “We just had to ensure that everything was installed to the manufacturer’s requirements.”

Manpower and scheduling posed the toughest hurdles, notes Pickel, but the general contractor, Lott Brothers of Austin, Texas, did a great job of keeping everyone on the same page. “We had weekly mandatory meetings that were set up by the G.C., and it was very helpful for us and other trades as well,” Pickel says. “Having to coordinate multiple trips is very common with new construction, unfortunately, but it’s great that we are able to do so much work. We did everything down to the gutters and downspouts — the full system — but it takes a lot of coordination and scheduling of the crews, especially when you have other jobs as well.”

One advantage of the multiple scopes of work was that Texas Traditions crews didn’t have to worry about coordinating transition details with crews from other companies. “It’s also nice for the owner,” Pickel adds. “If they have any issues or if they have any questions, they know the roofer did every bit of the metal on this job, and all of the TPO roof, and they know who to contact.”

Versatility is one of the company’s strengths, and for that Pickel credits the experience of the company’s owners, including his father, co-owner Mike Pickel, who has more than 30 years of experience in the construction industry, including 20 years working for a general contractor.

“He understands the complexity of coordinating multiple trades because he did it for so long from a G.C. perspective,” Pickel says. “His ability to know what needs to be done when allows us to be more effective and more efficient with our time. It allows us to be the expert in front of a general contractor because he was a general contractor. He worked with superintendents. He worked with multiple trades. His ability, knowledge and expertise within our company allows us to be the roofing expert.”

Texas Traditions strives to make the best use of that wealth of knowledge. “Each job is treated with care,” Pickel says. “It’s treated with expertise because it’s not just another job — it’s someone’s home, it’s someone’s office. We do apartment complexes, we do office buildings, we do residential homes, we do churches. Mike treats it with care, and it trickles down to everyone else to treat it with care as well.”

Colorful Exterior for Veterinary Hospital Comes Together Without a Hitch

Kimbrough Animal Hospital in Longview, Texas, is designed to provide top-notch care for its furry patients. The building includes surgical suites, treatment areas, and an in-house lab, as well as boarding and grooming facilities.

The state-of-the-art facility is housed in a striking complex highlighted by colorful metal roof and wall panels. It was a complicated new construction project on a tight jobsite, but experience and planning made for a smooth, textbook execution.

Complicated projects are nothing new for Curtis-McKinley Roofing and Sheet Metal. Headquartered in Longview, Texas, the company has been in business for 33 years and does a variety of commercial, industrial and residential work, including modified bitumen, built-up, single-ply and shingle roofs, as well as metal roofing and sheet metal fabrication. “We did all the metal on the project,” says Anthony McKinley, vice president of Curtis-McKinley. “We did the roof, the walls and soffit.”

McKinley was confident his crews could execute the project smoothly, and his confidence was bolstered by his experience working on other projects with the general contractor, Transet Company, and the manufacturer of the roof and wall panels, Petersen.

“We have a good relationship with Transet Company and we’ve done so much work with Petersen that they know our company and our guys,” McKinley says. “If there are any technical questions, they are very quick to help and get us answers, and inspections go great.”

The Roof and Walls

The roof and wall panels were manufactured from 24-gauge steel. The roof was covered with approximately 18,000 square feet of 18-inch PAC-CLAD Snap-Clad panels in Charcoal. The exterior also incorporates 4,400 square feet of 16-inch HWP panels in Slate Gray and 5,250 square feet of 12-inch Flush Panels in three colors: Slate Gray, Teal and Berkshire Blue.

Crews from Curtis-McKinley dried the roof in with TAMKO’s TW Metal and Tile self-adhered underlayment and tackled different phases of the project as the building came together. “We kind of did it all at one time,” McKinley recalls. “First, we had a roofing crew come out and put the peel-and-stick on the roof, and we measured for the roof panels. Then we started installing all of the trim and had a few guys start installing the wall panels.”

Petersen fabricated and delivered the wall panels, which were installed over plywood and cinder block walls using a man lift. On the cinder block walls, hat channels were installed to receive the clips. At two entrances, the Flush Panels were installed vertically. “We also installed regular flush soffit panels,” notes McKinley.

A representative from Petersen roll-formed the roof panels on the site. Some of the panels were more than 50 feet long, and this posed some logistical problems. “It was a very tight construction site,” McKinley explains. “We ran the panels on site and we had to lift them up with a crane. We couldn’t use a lift because there was no way to turn the lift around when the panels were loaded. There was one long driveway down one side, and we had to stack all of the panels in one direction and lift them straight up.”

Panels were lifted using a spreader bar as a cradle. “We strapped the panels to the spreader bar,” McKinley notes. “We only lifted about 10 panels at a time and our guys would receive them and stack them at points along the roof. We had about six or seven guys on the roof and the rest of the crew on the ground to strap down the panels.”

The crew started installing panels on the main roof and finished roof sections alongside the structure as the job progressed. Crew members were tied off 100 percent of the time, using temporary anchor points screwed into in the deck. “We started off on the main roof area and worked our way from the back to the front,” McKinley recalls. “The shed roofs were incorporated as we worked our way forward.”

While the main crew worked on the roof, a smaller group sometimes split off to install the wall panels. “We had a crew with a few extra sheet metal guys on it, and we moved them around as needed,” McKinley notes. “That way they could start on the walls as the roof progressed and the job wouldn’t lag on.”

Planning Ahead

The main challenge on the project was the tight jobsite, according to McKinley. “It was a very limited site,” McKinley says. “Once we got the roof panels on, we could breathe a little easier.”

Despite the cramped conditions, communication between the crews kept conflicts to a minimum. “Working with other trades went fine,” McKinley says. “The superintendent on the site was easy to work with. We worked with other subcontractors in Longview we’ve worked with plenty of times. Our guys knew their guys, basically, and they just coordinate well and work around each other as needed.”

The project moved along smoothly and stayed on schedule. “We were blessed not to have any big weather delays,” McKinley says. “When they were ready for us, we were able to get right out there and move things along in a timely manner.”

McKinley also credits the manufacturer for help executing the project. “There are four or five different colors on it,” he says. “Each entrance was a different color, and the walls and roof. That was pretty interesting. Keeping it all straight with the guys was a challenge.”

Again, planning ahead was essential. “It just took a little more communication,” McKinley says. “When we were making our trim, we just had to make sure it was the right color. It’s very easy to work with Petersen. On a job like this one, the technical aspect of it was really very simple, but seeing all of the different colors on this project come together was pretty cool.”

Curtis-McKinley crew members were able to execute all of the transition details themselves as they installed the roof and wall panels. “They were all standard details, really,” McKinley says. “Almost all of the transitions were something the guys have done hundreds of times.”

Exceptions included the large, irregularly shaped windows at the entryways, which were trimmed in red. “There were two entrances with windows that were a little different,” McKinley says. “One set had a sort of triangular shape, which was pretty straightforward to flash. The other had a circular window, and that took a lot of time and coordination with the window people to ensure that we got it watertight with the flashing. Getting the trim for that wall custom made and fitting perfectly was a bit of a challenge.”

Taking a complicated project and making it look easy is one of the strengths of Curtis-McKinley Roofing. “The key is having the right guys,” McKinley says. “We are blessed to have very experienced professional roofers and sheet metal installers. Our sheet metal guys have done this for years. That’s getting harder to find these days, and we still have some older guys that know how to do it. They’ve done so much of it that I often rely on them to tell me, ‘This is how it needs to be done,’ or ‘This is a better way to do it.’ Then we just make sure everything conforms to the plans and specifications, and we ensure the installation integrity. Obviously the most important thing is to keep the water out.”

New Roof Provides Security at Senior Living Complex

Photo: Johns Mansville

The Preserve At Palm-Aire is a landmark senior living community in Pompano Beach situated on 13 acres of lush, beautiful grounds in South Florida. Offering both independent living and assisted living programs, the health care facility’s primary focus is on preserving residents’ quality of life in every way possible.

The independent senior lifestyle at The Preserve At Palm-Aire is all about maintenance-free living, and that philosophy influenced the choice of a new roofing system for the facility.

The re-roofing of The Preserve At Palm-Aire was complicated by Mansard-style roofs and 5-foot to 6-foot high parapet walls that greatly restricted access to the existing roofing system, which was installed on a lightweight structural concrete deck. The use of trash chutes was impossible, so a large crane and dumpster were used to remove the roofing debris.

“What concerned us most was using such a large crane around an immaculately landscaped property fully occupied by tenants especially sensitive to excess noise and vibration,” says Geo Madruga, commercial project coordinator for A-1 Property Services Inc., the Miami-based roofing contractor on the project. Another important concern was that the low-slope roof had numerous penetrations, including those for 30 large HVAC units and various pipes and stack vents.

Finding a Solution

A-1 Property Services Inc. competed with several other contractors on an open spec bid. With the help of JM Sales Representative Lewis Buckner, A-1 advised the property owner that a 60-mil fleece-backed PVC membrane with DuPont Elvaloy KEE would provide the longevity, energy efficiency and chemical resistance required for the project. “We really pushed the PVC fleece backed as the superior roofing system and a unique solution for this building,” says Madruga. “We also felt more comfortable with JM’s PVC membrane due to our long track record with the product.”

Adhered directly to the concrete deck with a water-based adhesive, the fleece-backed PVC exceeded Broward County’s 175-mph wind resistance requirement. The PVC membrane’s high reflectivity also earned an energy efficiency rebate from Florida Power & Light Company. The product was also easy to install, depite the numerous penetrations, notes Madruga. “While there were definitely many unique penetrations, our 10-man crew had no problems with the heat-weldable PVC membrane,” he says.

Madruga’s concerns — and his company’s name — both reflect A-1’s desire to create long-term relationships with clients that include expert maintenance services. “We met the expectations of the owner’s roof consultant, but with offices in Washington D.C., the client placed a tremendous amount of trust in the roofing manufacturer and contractor,” adds Madruga. “We are specialists, and we don’t just walk away from any roofs that we install.”

The New Parkland Hospital Is Already a Dallas Landmark

Parkland Memorial Hospital is located on a 64-acre health care campus in Dallas. The 2.1 million-square-foot complex includes an 862-bed, full-service acute-care facility. Photos: Aerial Photography Inc.

When it was time to replace the Parkland Memorial Hospital — a Dallas, Texas, landmark constructed in 1954 that served as a safety-net facility for Dallas County for over half a century, and which held notoriety as the location where President Kennedy was rushed after being shot in 1963 — everyone recognized they would be undertaking a high-profile project. This became even more apparent when the plans for a new Parkland hospital were unveiled: a 2.1-million-square-foot, 17-story, state-of-the-art, 862-bed, full-service acute-care facility located on a 64-acre health care campus in the Southwest Medical District. The $1.33 billion project resulted in one of the largest health care facilities ever constructed as a single project.

Because of the scale of the new Parkland hospital project and the fact it was being funded with public dollars, a conservative and careful approach to the planning was paramount. A planning and construction team was assembled to tackle the mammoth project, which included two architecture firms — HDR Inc. and Corgan Inc. — and four large contracting firms — Balfour Beatty, Austin Commercial, H.J. Russell & Company and Azteca — that formed a joint partnership called BARA for the job. A “collaborative project delivery” model was adopted to keep all the stakeholders on the same page, which included the designation of a central “co-location” office where members of various involved firms could meet, collaborate and concur on direction. Numerous consultants were brought in, and through a careful planning process over a period of two years, designs, material specifications and additional partners were analyzed and selected.

Early in the planning process, SOPREMA’s local sales partner, Conner-Legrand Inc., was brought into material specifications discussions with the architects and contractors planning the project. The planning team recognized the importance of finding the “best roof they could put in place” for this critical environment that was designed to last for decades. After numerous rounds of careful vetting, a final qualified roofing system was chosen that fit that criteria: a SOPREMA-manufactured, high-performance, two-ply, SBS-modified bitumen roofing system.

“Consistency and reliability in the marketplace don’t develop overnight, and in the case of a project like the new Parkland hospital, everyone accounts for that,” says Luke Legrand of Conner-Legrand Inc. “You’re dealing with the most discerning audience you can imagine, and while it takes time to make decisions, the final choice of materials speaks volumes. The decision-makers wanted one reputable manufacturer that could provide everything from the primer to the cap sheet and offered a strong warranty, and not every manufacturer has the horizontal and vertical breadth to provide that. In this case, however, the planning team found what they were looking for in SOPREMA.”

Raising the Roof

The new hospital featured flat rooftops at multiple levels that all needed to be made watertight for decades to come. The roofing system needed to be designed in a way that accounted for a helipad, consistent rooftop traffic, extensive rooftop equipment, lightwells and various utility platforms. A lot stood in the way of Anchor Roofing, the installer, but the meticulous planning for the project meant that all contingencies had been considered by the time application of the waterproofing system began.

After installing insulation, a vapor barrier and SOPRABOARD, the Anchor Roofing team started on the two-ply roofing application. They first put down a layer of SOPRALENE Flam 180 SBS-modified bitumen base-ply membrane to provide waterproofing protection for the building. The various other tradespeople who needed to work on the rooftop could then go about their business, and any necessary repairs were made to the waterproofing base layer before a SOPRASTAR Flam SBS-modified bitumen reflective cap ply layer was installed on top. The chosen cap layer was not only functionally strong and long-lasting, but also white and highly reflective, providing energy savings and ultimately contributing to the hospital’s achievement of LEED Gold status from the U.S. Green Building Council.

The two-ply SBS-modified bitumen roofing construction was also chosen because the waterproofing system can be easily refreshed 25–30 years down the road to extend the roof’s lifecycle without a full tear-off. The foundation of the system can stay intact while the top layer is rejuvenated, giving the option for an additional warranty and ensuring the building is protected against the elements for another 20–30 years. This not only helps the health system to save money in the long run and avoid contributing unnecessary waste to landfills, but also helps the hospital avoid disruption to operations in a sensitive environment where recovering patients must be protected from invasive construction processes.

A Dallas Landmark

Throughout the course of construction, 162 professional staff members and 1,400 on-site workers collaborated to construct the new Parkland hospital. It was officially dedicated in March 2015, and patients and staff had all moved in by August. The facility now averages more than 1 million patient visits per year, with roughly 30,000 people traveling through its doors each day. The roof has performed well, and all stakeholders in the project have felt confident that the right waterproofing system for the job was chosen. Given the careful planning, beautiful design and strong material choices that went into the project, it has already received a number of awards and is well positioned to remain a Dallas icon for decades to come.

During Hospital Expansion, Contractor Protects Patients – and the Environment

It’s not often a roofing contractor installs a new roof on a building before removing the old one, but that was just one of the wrinkles encountered by The Duerson Corporation during the recent expansion of Pella Regional Health Center in Pella, Iowa. The project involved adding a new third floor to the existing two-story hospital without disrupting the care of the patients below.

Protecting patients and meeting the needs of the hospital were the top priorities on the project, but another key focus was sustainability. Thanks to the initiative of The Duerson Corporation and Duro-Last, the roof system manufacturer on the project, almost all of the components on the existing roof were recycled, including the membrane, insulation, screws and plates.

The Game Plan

Based in Altoona, Iowa, The Duerson Corporation has been in business since 1986, specializing in commercial and industrial roofing, both new construction and retrofit. Kirk Duer, the company’s president, and Tanner Duer, head of business development, shared their insights on the Pella Regional Health Center Project with Roofing.

The Duro-Last roofing system included a vapor barrier, polyiso insulation, a cover board, and 50-mil white PVC membrane. Details included custom-fabricated curb flashings, walkway pads, and edge metal. Photos The Duerson Corporation.

They note that the goal on every project is to meet the client’s needs. “The hospital is a good example of that,” Kirk notes. “We took care of some maintenance and leak issues in the beginning, and then as time went on and trust was established, we did some re-roofing projects for them. Then they did this addition. It all flowed very well together.”

In a nutshell, the expansion plan involved erecting the steel for the new third floor, adding the roof deck, and installing the new roof system. The existing roof was left in place during this phase of construction, as the hospital was still active. After the walls were completed, the old roof system could be removed and recycled, and finally the interior work could be completed.

The first step involved erecting the steel for the new third floor. Kirk credits the hospital administrators for detailed planning before the project even got underway. That was the reason the existing roof was home to multiple 2-foot-by-2-foot boxes, complete with curbs and flashing.

“Those boxes covered the steel from the I-beams that were coming out of the roof, ready to receive that third floor,” Kirk notes. “When those boxes were removed, they just took their new steel and went up. It’s one of the more unique things I’ve ever seen in my history in the industry.”

As the steel went up, flashing the newly exposed I-beams was the first phase of the roofing work. “In the very beginning, once the general contractor removed those boxes, we added membrane and insulation around the I-beams and made sure they were watertight while the steelworkers erected their steel,” Kirk notes. “It was critical to keep it watertight because they still had patients right beneath us.”

Installing the New Roof

The new roof system covered an area of 27,600 square feet, bordered on one side by a long, curved parapet. The roof was installed over a structurally sloped steel deck with internal drains. “The first thing we did was install a vapor barrier over the entire deck,” Tanner notes.

The system consisted of Duro-Guard polyiso insulation with an R-value of 30, DensDeck cover board, and 50-mil Duro-Last white PVC membrane. Details included custom-fabricated curb flashings, Roof Trak III walkway pads, and coping and edge metal from Exceptional Metals.

Hospital administrators wanted a warranty from one source, notes Kirk. “Duro-Last refers to it as edge to edge, deck to sky,” he says. “Every component is supplied by Duro-Last and warranted by them for a full-system warranty. This particular administrator is adamant that this is what he wanted, and that’s what we delivered for them.”

Weather was not an issue, but the crews had to be ready to move quickly in the event of emergencies. “Work took place in September and October, which is about the most beautiful time of the year for us,” says Tanner. “The only unusual thing was that we had to have walkie-talkies on us at all times so they could alert us whenever a helicopter was coming in. Plant ops would notify us when a helicopter was coming in, and basically anything we had in the air we had to move down to the ground. We obviously wanted to make sure Pella Regional was not going to have a problem with us when a patient was flying in.”

The roofing installation was pretty straightforward, notes Kirk. There was one area on the lower roof that was an exception, as the new construction blocked access to the drains. “Originally the roof sloped in one direction, but because of the design of the new part of the building, we had to change the slope,” he says. “We had to turn everything around so water would flow in the other direction.”

On this section, the existing roof was torn off and removed, and tapered insulation was used to provide the proper slope. It was installed on a concrete deck over a working section of the hospital, so the installation was a bit tricky. “Rather than starting at the drain, which would be the easiest thing to do, we had to start at the furthest point away,” Kirk notes. “We were adding so much insulation, we didn’t want to create a bathtub, if you will. We had to start at the high point and work our way downhill so when we got to the drain, we’d have the correct elevation.”

Recycling the Old One

Once the third floor was closed in for the winter, it was time to remove the existing roof. “That was the fun part,” Tanner says.

The old roof was removed through a window. “We had an opening that was approximately 5 feet wide and 4 feet

tall,” Tanner recalls. “We took a fork lift with a BOXhaul on it and basically went up to the outside of the window and stuck it in there as far as we could without damaging any of the structure and started removing the material.”

No gas-powered vehicles were allowed to operate in the interior space. The fasteners had to be unscrewed and separated by hand. “When we removed the material, we tried to cut along the seams so we could see the screws and plates,” notes Tanner. “We sorted those out, and in the end we had more than 1,000 pounds of screws and plates we took back to our shop to be recycled.”

The existing membrane was cut up into 5-foot strips. Sections were rolled up and bundled for removal using a portable bander. Once the BOXhaul was full, it was taken to a flatbed trailer. “We completely filled the 20-foot trailer with old material to be recycled,” Tanner says. “In the end, there was 7,200 pounds of Duro-Last membrane that we recycled.”

The membrane was recycled as part of Duro-Last’s Roof Take Back Program. The company recycles the membrane, using it to construct products including walkway pads. “We’re lucky enough to have a Duro-Last plant in our state, and I actually took that load of material to be recycled to Sigourney one day,” Tanner says. “When I got there, they took a fork lift out there and unloaded it for me.”

The expanded polystyrene insulation was also removed and recycled. It was taken to Insulfoam, the original manufacturer. “The insulation necessitated a few more trips because it was so bulky,” Tanner says. “We kept an empty tractor trailer on site. In the end, we filled up three of those with approximately 120,000 board-feet of insulation that we took off of that project.”

The Duerson Corporation recycles as much material as it can throughout the year, including scrap metal and PVC membrane, which is stored in Duro-Last approved containers until there is enough to be transported to the plant.

“I thank Katie Chapman at Duro-Last for getting this program up and running and making us aware of it,” says Kirk. “Otherwise, that material would’ve just ended up in a landfill.”

Participating in the membrane recycling program was an eye-opener for everyone at the company. “One thing leads to another,” Kirk says. “We started recycling the roof membrane, and then you realize that there are other things you should think about. What do we do with the insulation? What do we do with the screws and plates? We started looking for ways to recycle everything, and pretty soon a full-blown sustainability program is born. It really does change the way you think once you buy into the system.”

The New Floor of the Hospital

After the general contractor removed the old vapor barrier with a floor scraper, the new third floor section was converted into a brand-new, pristine Obstetrics and Gynecology unit. The difference between the construction site and state-of-the-art hospital wing is striking.

“What we knew as the concrete roof deck was also designed to serve as the finished floor of the hospital,” Kirk says. “The new O.B. unit is just beautiful. If you look at that you can’t even imagine, unless you’ve been through the whole process, that the area with carpet and tile you’re looking at months ago used to be the roof.”

Safety for the roofing crews is always a priority at The Duerson Corporation, but safety precautions on this project also included ensuring the safety and security of the people in the hospital. “It was critical that we were always aware of the patients underneath us,” Kirk notes. “We had to be very mindful about the positioning of our generators, for example, so the exhaust wouldn’t be sucked into the fresh air intakes.”

Tanner points out that a checklist is prepared for each project to make sure everyone is aware of the client’s needs. This is especially important in health care projects like this one. “If someone goes out to take care of a leak call, for instance, we make sure they know everything they need to know to keep the client happy,” Tanner says. “With a health center, you have to take extra precautions. This can include items like making sure when you’re walking across the open roof that you don’t look into a patient’s room.”

“We’ve learned a great deal from working with Pella Regional Health Center in terms of just how mindful of everything we need to be,” Kirk says. “We recognize each of our clients, even though they all have a roof over their head, they all do something different for a living. In reality, everybody in any trade needs to recognize what your client does and what you need to do to be mindful of that.”

It takes communication to understand clients’ needs and build long-term relationships with customers. “We’ve got clients that we’ve serviced for 26 years,” Kirk says. “We’re all here to serve other people. In our case, it’s in roofing. Whether it’s a hospital or a convenience store, we’re serving them, and it all starts with that relationship.”

Metal Roof and Wall Panels Add Sleek, Modern Look to New Medical Complex

When Brice Harris of Harris Craig Architects began designing a new health complex in Tyler, Texas, he knew his client wanted to maintain continuity with the company’s other medical facilities but at the same time update the look. The roof and wall panel systems became the key to meeting both design goals.

The standing seam metal roof and metal wall panel systems are now the signature architectural features of the CHRISTUS Trinity Mother Frances Herrington-Ornelas HealthPark. The new construction project encompasses some 43,000 square feet of space housing an urgent care clinic, medical offices, a physical therapy area and a fitness center.

The Design

Harris Craig primarily focuses on institutional projects, including schools. About a quarter of the firm’s work involves health care facilities. On this project, a merger while it was underway added a few wrinkles in the design process.

Crews from Tyler Roofing installed the metal wall panels, which included PAC-CLAD HWP panels and PAC-CLAD flush panels from Petersen, as well as Longboard Siding in Dark Cherry Wood Grain from Mayne Coatings Corp. Photos Petersen.

“The hospital system is CHRISTUS Trinity Mother Frances,” Harris notes. “When we began work on the project, it was for Trinity Mother Frances, and they partnered up with another hospital network, so part of the challenge on this job was switching the branding in the middle of the project. Luckily our overall design fit very well. The branding changes were more prominent on the inside of the building and didn’t have much effect on the exterior design.”

The property is strategically located at the intersection of two busy roads, and the highly visible site posed some concerns. “We really didn’t have a back of the building,” Harris explains. “The challenge of the design really was to efficiently present this building well both to the street and to the people who would be approaching it from the opposite side. That actually drove a lot of how the building form turned out, along with our desire to both help modernize the look of the clinic a little bit and to tie it back to some of the existing branding.”

The roof was designed to echo the other structures but uses different materials. “They share the prominent use of the gable on the building, but here we brought it forward into a contemporary design aesthetic,” Harris says.

For this project the design team specified a standing seam metal roof manufactured by Petersen that encompasses approximately 6,000 square feet. Low-slope roof sections over each wing were covered with 60-mil TPO roof system manufactured by GAF.

Wall panels were used to extend the sleek, modern look down to the ground, in contrast to the many brick buildings in the area. “We wanted to lighten up the look a little bit and bring in some new materials as part of the modernization,” Harris says. “We have composite panels, horizontal panels, and wood-look aluminum panels.”

Key concerns included making sure the various systems tied together perfectly. “The transition between the wall and roof is a very important detail for us,” Harris notes. “The most complicated areas for us on this project would be at the front of the building with the big glass windows and composite panels, and areas where the composite panel ties into the TPO roof and the metal panels. That was probably the trickiest part of the design.”

The Installation

Tyler Roofing was a natural fit for the project due to its established relationships with the architect and general contractor, WRL General Contractors, headquartered in Flint, Texas. “We do a lot of work in Tyler, and we’ve worked on a lot of Harris Craig projects,” says Tommy Ray Sukiennik, a 24-year veteran at the company, which was founded by his father and uncle 35 years ago. “We’re one of the competitive contractors in our area.”

The company’s share of metal roof and wall panel work is increasing, notes Sukiennik. “We’ve been doing standing seam roofs for more than 20 years. Lately we’ve been doing a lot of wall panels — Petersen HWP wall panels, flush mounts, things like that. As far as metal goes, we try to be diverse enough that we can install any system that comes out on the plans.”

Tyler Roofing installed the roof systems and wall panels on the project, along with gutters, soffits and trim. Work began with the fully adhered GAF EverGuard TPO roof system, which was installed over the metal deck, 4 inches of polyisocyanurate insulation and a half-inch cover board. The low-slope roofs over the wings house the HVAC units, but details involved were straightforward, notes Sukiennik. “It was all pretty basic,” he says. “At some points we had to tie in the TPO roof, the metal on the parapet wall, and the metal on the exterior wall all together.”

To dry in the gable roof, crews installed 4 inches of polyiso insulation and a self-adhering waterproofing underlayment. They also installed custom-fabricated gutters. “We built a gutter that hangs off the edge of the eave that a starter clip goes on top of, so it’s integrated into the roof,” Sukiennik notes.

The 18-inch-wide, 24-gauge PAC-CLAD Snap-Clad roof panels in Champagne Metallic were delivered to the site. “We order all of the panels to length from Petersen,” Sukiennik says. “One of the plants is here in Tyler, and actually not far from the job, so it was very convenient. All of the rest of the trim, parapets, wall flashings and components we fabricated ourselves in the shop with metal they supplied.”

The roof panels were raised to the roof using a SkyTrak lift with specially built cradles. The wide-open jobsite and the flat roofs on either side of the gable made the roof area easily accessible. “It was just a straight run gable roof. There are no penetrations in the standing seam,” Sukiennik says. “The panels are easy to install. The Snap-Clad panels just pop together.”

Tyler Roofing crews also installed the metal wall panels, which included 16-inch-wide, 24-gauge PAC-CLAD HWP panels in Dark Bronze from Petersen; 12-inch-wide, .032-inch aluminum PAC-CLAD flush panels from Petersen; and 6-inch-wide extruded Longboard Siding in Dark Cherry Wood Grain from Mayne Coatings Corp.

Wall panels were installed using scissor lifts and ladders. “We kept running a laser to make sure everything was horizontal and lined up,” says Sukiennik. “Then we finished it off with the trim and the cap. We tied everything into the expansion joints and trimmed it out so it was as clean as could be.”

The workload on this project was greater than usual, so skillfully managing the crews was important. “Usually we roof a building, and then we have to wait on the other contractors to do the brick and stucco on the exterior, and then we have to come back and trim it out and finish,” Sukiennik explains. “On this project, we did probably 70 percent of the exterior of the building, so we were working on the building continuously while we were doing other projects.”

The good news was that the crews had most of the work under their own control. “There were no issues of expecting someone else to make sure things were done the way we wanted them done. We tied everything in ourselves.”

Work was completed in the summer, so the heat was an issue. “When we put the wall panels on during July and August, it was pretty hot, so we had to work on one side of the building in the morning and then switch sides in the afternoon,” Sukiennik says, noting that his company is used to coping with extreme conditions. “In East Texas, we can have every type of weather there is within three days almost.”

Team Effort

Sukiennik credits WRL General Contractors for the well-coordinated jobsite. “We work on a lot of projects with the same contractors, so we all watch out for each other,” he says. “We do a good job of staying on top of things. We do a lot of work here, and this our family town, so we take pride in our work. We do the best we can.”

On the gable roof, Tyler Roofing installed 18-inch-wide, 24-gauge PAC-CLAD Snap-Clad roof panels cut to length by Petersen. Tyler Roofing also fabricated and installed trim, parapet metal, wall flashings and gutters. Photos Petersen.

Comprehensive details and pre-production meetings ensured the installation was uneventful, according to Sukiennik. “The architect does a good job of making sure everything blends,” he says. “We usually don’t have issues with details and things like that. They try to make it as smooth as could be.”

During construction, members of the design and installation teams stayed in touch to make sure everything went according to plan. “This project was only about a mile from our office, so it was convenient to stop by, and it was a project we were really excited about,” Harris recalls. “We meet frequently with our installers to discuss details. We like to learn what works and what doesn’t work from the crews in the field. We want to listen to the wisdom of the guys who are out there actually doing the work.”

It’s all part of making sure the building owner is satisfied. “What we were excited about for this project was the opportunity to define a new look for CHRISTUS Trinity Mother Frances to help them match the quality of their facilities with the quality of care in Tyler and the region,” Harris says. “We see one of our strengths as building long-term relationships with our clients to give us the opportunity and trust to do that.”

Medical Research Facility Showcases Eco-Social Construction

Kemper System Belfer Medical Research Building

The rooftop on the Belfer Medical Research Building not only houses HVAC equipment but serves as a rainwater detention system. The reinforced membrane waterproofing system by Kemper System was applied to the roof deck before the pavers were put in place on a pedestal system.

The Belfer Medical Research Building on the campus of New York’s Weill Cornell Medical College was designed to be a 19-story model of eco-social construction. Designed by Todd Schliemann of Ennead Architects, the building showcases a number of sustainability features, including a storm water detention system on the roof.

Built for a cost of more than $630 million, the tower includes 13 stories of research laboratories. The tower has three roof levels at the 17th, 18th and 19th floors. The rainwater detention system, known as a “blue roof,” not only helps regulate storm water discharge, but it feeds a water fountain and irrigates planters on the second-floor terrace.

In general, rainwater detention systems can either collect water in holding tanks and then meter it to the public sewer system, or retain it on a waterproofed roof expanse. The blue roof on the Belfer Research Building uses the latter strategy. It complies with New York City requirements and can hold up to 3 inches of water.

Roof Materials

Proper waterproofing on the project is essential. The solvent-free and odor-free KEMPEROL 2K-PUR cold, liquid-applied membrane system was used for waterproofing the blue roof. It was also used on the terrace and fountains on the lower level. The reinforced membrane system is designed for long service life and backed by an extended-wear warranty.

Eagle One Roofing Contractors Inc. of Astoria, N.Y., a certified applicator of the Kemper System, applied the waterproofing system. The two-part resin system is designed to fully adhere to the substrate, and is fully reinforced with fleece. The resulting membrane is completely seamless and unaffected by ponding water and ice. According to the manufacturer, it resists exposure to UV light, chemicals, oils and solvents. It is impervious to bio-deterioration and is both root- and rot-resistant, so it is also ideal for green roofs and landscaped areas.

Roof Report

The supporting structure below the roof was designed to carry the water load, with an allowance for heavy snow or ice buildup. The roof deck is concrete slab and includes a layer of rigid insulation below the waterproofing membrane for added energy efficiency. The gravity-fed drainage system was carefully sized to control the speed of drainage without the use of pumps, sometimes required for rainwater detention systems that use holding tanks. On the roof sections, the waterproofing sections were topped with concrete pavers on a pedestal system.

Construction at the Weill Cornell Medical College, both interior renovations and new construction, is designed to meet a minimum LEED Silver status. This project was designed to achieve Gold certification, the nationally accepted benchmark for the design, construction and operation of high-performance green buildings.

On the south side of the building, Ennead created a double-skinned, fritted glass curtain wall with openings and sun-shading devices that absorb the sun’s heat before it gets trapped inside, which would require the HVAC system to pump out more cold air. Continuous ribbon windows flood the building with natural light, and energy-efficient HVAC, lighting controls and water-conservation systems save on power and resources. The building’s green infrastructure is expected to shrink Weill Cornell’s energy bill for it by about 30 percent and reduce carbon dioxide emissions by about 26 percent compared to a building complying with the minimum requirements set by typical industry guidelines and standards.

The building includes a high-tech, multi-zoned HVAC control system to manage the indoor environment within different spaces. Biomedical laboratories, for example, generally require special air filtration systems supported by high-volume air circulation. Each of the laboratory levels includes four fume vents to the outside, except for the chemistry laboratory on the top floor, which uses 40 vents. In addition to thermostats and humidity sensors, indoor spaces utilize occupancy sensors to assist in regulating the ambient indoor environment and lighting to improve energy efficiency.

Insulated Metal Panels Save Time and Labor in Construction of Inmate Hospital

An insulated metal panel system from All Weather Insulated Panels was chosen for the project because of its durability, energy efficiency and ease of installation.

An insulated metal panel system from All Weather Insulated Panels was chosen for the project because of its durability, energy efficiency and ease of installation.

Under pressure from the federal government, the state of California had to build a new health care facility for its prison inmates—and do it fast. The logistics were daunting.

Planning for the 144-acre construction site that became the California Health Care Facility inmate hospital in Stockton, Calif., had to account for 1,700 personnel on the site at any one time. Physically, it was an imposing project: 23 buildings adding up to 1.2 million square feet, with 792,000 square feet of roofing.

Since there was very little space to store roofing material on site, it became clear in the planning stages that production had to be paced with installation, and a choreographed dance of trucks, forklifts, and installation crews had to be executed well in extremely compact areas.

That’s when using an insulated metal panel (IMP) system from All Weather Insulated Panels (AWIP) of Vacaville, Calif., dawned on the team at Roland Construction in Stockton.

The team realized using IMPs could save in both onsite manpower and installation time. “This being the largest project Roland has ever completed, as well as the demand for over 50 of our workers on site, plus personnel from other companies, the challenges were formidable,” said Jim Hoagland, the owner of Roland Construction.

Roof Materials

Representatives of Roland and the general contractor firm of Clark/McCarthy worked with the California Department of Corrections and Rehabilitation (CDCR) prior to the bid date to make sure that the IMP roof system would be acceptable to the state. Not only was it deemed acceptable, the state considered IMPs an upgraded component in the final design-build package submitted for consideration. The specification was amended to include insulated metal panels for the architectural roofing before sub-contractors submitted bids.

After the bids were opened, Roland Construction and AWIP earned the opportunity. In January 2012, work began immediately on the design of the 23 buildings. AWIP’s 4-inch thick SR-2 standing seam insulated roof panel with a 22-gage outer skin coated in Natural Green Kynar paint became the choice. The excellent insulating properties of the sandwich-style panel with an R-value equal to 32 in the darker color complied with the project’s LEED Silver Certification.

Roof Report

In May 2012, three five-man crews began work on adding the insulated metal panels to the roof. It soon became apparent that each crew could install panels quickly, safely and efficiently.

Over the course of six months, each crew using a small crane could install up to 7,650 square feet of roofing, meaning 15 workers added a total of nearly 23,000 square feet of roofing per day. Following behind the roof paneling crews were several other crews installing AWIP 2-and-half-inch DM40 wall panels, flashings, and trim to encapsulate the 192 fixtures that allowed natural light into the buildings.

The California Health Care Facility in Stockton is comprised of 23 buildings on 144 acres. A total of 792,000 square feet of roofing was installed on the project.

The use of a vacuum lifter provided by Automatic Panel Lifting System (APLS) of Auburn, Calif., proved essential in the installation of the panels. The APLS lifters are designed to be hung from a crane or forklift. With the proper attachment setup, they are capable of raising panels up to 60 feet long weighing approximately 600 pounds each.

With the panels being able to be lifted and released in a matter of seconds, production was increased dramatically to meet the project’s breakneck schedule.

With a total cost of $906 million, the project was California’s largest public works project in 2012. Hoagland points out that the reduction in installation man-hours not only saved schedule time, but more than made up for the additional material cost over a more traditional built-up insulation and metal roof system.

“With all the pre-planning with our supplier, AWIP, and their going the extra mile for us, we could not have accomplished this project in such an efficient and timely manner,” notes Hoagland. “The use of AWIP’s insulated metal roof panels for this project proved to be the decision that made this job feasible.”

AWIP Ready for 2020 Regulations in 2017

Insulated metal panels consist of closed-cell foam composite encased by two pieces of galvanized steel. AWIP’s SR2 roof panel has a trapezoidal design to increase the panel’s overall rigidity.

By 2020, as regulated by the California (CPUC) Public Utilities Commission, all new residential construction in California will have to meet Zero Net Energy (ZNE) requirements. In essence, the regulation stipulates that the amount of energy a residential building takes off the power grid must be balanced by energy the residence generates and returns to the grid.

William Lowery, the president of All Weather Insulated Metal Panels in Vacaville, California, says his company “is ready for 2020 in 2017.”

Lowery believes that insulated metal panels (IMPs)—the “sandwich-style” roofing component consisting of closed-cell foam composite encased by two pieces of galvanized steel—can propel the North American construction industry into a new era.

“Insulated metal panels are better, faster and cheaper, and we’re at the forefront of changing construction in the United States,” says Lowery.

As an example, AWIP’s SR2 roof panel has a trapezoidal design that increases the panel’s overall rigidity, making it safe for longer spans and foot traffic despite using a lighter-than-usual 26-gauge steel, which reduces overall weight.

Furthermore, according to Lowery, insulated metal panels require far less specialized equipment to install than traditional building materials and, due to their self-aligning, tongue-in-groove joinery, they are a snap to fit together. Once assembled, they provide insulating values above R-50, securing the building’s thermal envelope.

William Lowery, the president of All Weather Insulated Metal Panels, believes insulated metal panel systems can help California homeowners meet strict upcoming residential building regulations.

“The SR2, to name one, not only meets the new CPUC energy needs, its means a savings in needing fewer solar panels,” says Kim Harrell, vice president of sales for AWIP. “Roof panels reduce the cost of materials and construction time. They will play comply with the CPUC’s aspirations for California and have significant role in helping new and existing construction projects all over the country.”

Finally, AWIP’s SR2 roof panel with the S-5! Clips makes attaching solar panels quick and easy without piercing the underlying substrate, thereby preventing and air, vapor or water leakage.
