2017 – 2019


The carbon steel piping installation for the heated and chilled-water HVAC system on this project had fallen badly behind schedule


Switching to Aquatherm polypropylene-random (PP-R) pipe allowed the installation crews to move, mobilize, and fabricate the pipe quickly and efficiently, and moved the project ahead of schedule


  • The speed with which aquatherm polypropylene-random (PP-R) pipe can be heat fused compared to welding steel was crucial on this project

  • The ability to fabricate piping assemblies and deliver them to the site allowed the contractor to maximize the amount of fusion work completed each day
  • The durability and longevity of PP-R pipe were key in a facility that is operational 24/7/365


On a project as highly anticipated as the expansion of the Seminole Hard Rock Hotel & Casino in Hollywood, FL, the ability to stay on schedule is paramount. Guests are awaiting twice the amount of casino space, a Bora Bora-inspired pool paradise, an iconic hotel tower in the shape of a giant guitar, a new Hard Rock Live arena, and much more. It will be the ultimate venue for accommodations and entertainment when Super Bowl LIV comes to Miami in February 2020, so it must be good to go well before then.

With so much on the line and no time to waste, Suffolk-Yates, the general contractor, decided to regroup after an HVAC contractor struggled and fell behind on the carbon steel piping installation for the casino’s heated- and chilled-water systems. Suffolk-Yates brought in Kirlin, a construction company that had bid on the project, to see if they could get it back on track.

Kirlin Senior Vice President Troy Norris said the company knew the solution would have to be as innovative as the Seminole Tribe’s $1.5 billion project itself, and they were ready to take on the challenge.


Kirlin needed to fabricate and install a piping system to connect a central chiller plant to all of the casino’s outlying buildings, including the iconic guitar-shaped hotel and spacious pool area. The company had originally planned to use carbon steel joined with mechanical couplings for the casino expansion and remodel, but when asked to take a second look at the jobsite setup they decided that the situation called for a more innovative approach. 

To that end, Kirlin consulted with Ferguson, the largest wholesale distributor of residential and commercial plumbing supplies and pipe, valves and fittings in the U.S., to get Ferguson’s thoughts on how to remobilize the job and get it back on schedule.

Kirlin liked what they discovered about aquatherm polypropylene-random (PP-R) pipe, including weight up to 70 percent less than metal pipe, which allowed the installation crews to move, mobilize and fabricate the pipe quickly and efficiently with less fatigue and risk of injury; an anticipated life span of 60 or more years; resistance to corrosion and scaling; and virtually leak-proof heat-fusion connections that require no welding, open flames, or fire watch.

After seeing what it offered, Norris said Kirlin abandoned the conventional welded system and adopted the fusible PP-R piping system as its new build strategy.


But Kirlin had another challenge to face — fusing large-diameter (24-in.) pipe with heavy fusion equipment that didn’t seem ideally designed for working in tight spaces. Kirlin discussed this with Ferguson, and Ferguson was able to offer a prototype butt fusion machine from McElroy, a longtime fusion machine manufacturer based in Tulsa, OK. The prototype was lightweight and designed specifically for work in close quarters.

Once Kirlin tried the prototype machine, Norris said they didn’t look back. It was unobtrusive to work with, easy to handle on a scissor lift, and featured a lightweight, modular carriage. After successful field testing on this project and others, the prototype became the Acrobat™ 630 featuring a QuikFit™ carriage. It was launched in the summer of 2018. Duane Hettich, Category Sales Specialist for Ferguson, said that the Seminole Hard Rock Hotel & Casino project was the first opportunity to use the new Acrobat 630 on an indoor install of large-diameter PP-R pipe.

“Some of the installation felt like we were in a phone booth,” he said. “They had already installed stud walls so we didn’t have an open space to work.”

According to Hettich, the machine worked very well right out of the gate. Almost all of the work on the 24-in. pipe was overhead and between walls; that meant nearly all of the fusions on the 24-in. pipe were done in the air on a scissor lift. But instead of having to lift the fusion machine’s entire carriage, Kirlin’s crews were able to remove the top jaws and place the cylinder assemblies, lower jaws and guide rods on the pipe first. The top jaws and other components were then assembled around the pipe by hand. For smaller pipe on the project, Kirlin purchased from Ferguson two Acrobat 250 models, which butt fuse up to 8-in. pipe. For socket fusion, they used hand tools and leased several McElroy Spider™ 125s.


Kirlin’s fusion operators were new to PP-R pipe and there was admittedly a learning curve. It was a product that changed their entire build modality, so good training was crucial. 

“Ferguson did a phenomenal job of putting on numerous trainings,” Norris said. “They also were instrumental in having McElroy’s team engaged with us onsite.”

According to Norris, although Kirlin’s installation crews had to get used to working with a new pipe material and different fusion equipment, they were able to be very productive once they got to fusing.

“I know we’re getting more proficient with the more time the guys spend working with the product,” Norris said. “When we initially started out, we were approaching building strategy similar to carbon steel. Now we’re seeing more footage of PP-R pipe going up every day.”


There were multiple construction projects going on simultaneously at the Seminole Hard Rock Hotel & Casino, and Norris said the light weight of PP-R was instrumental in keeping things moving on the piping end. He noted that handling and transporting the PP-R pipe is dramatically easier than steel would have been. “aquatherm allowed us to hang long runs of it overhead and get more pipe in the air quickly,” Norris said.

A significant portion of the fusion was completed offsite at Kirlin’s shop in West Palm Beach, about 20 miles north of the site, and Norris said that sped up the schedule greatly. The company scheduled pipe deliveries for nights and off hours, allowing them to maximize the amount of fusion work completed during the day.


Hettich said Ferguson supplied about seven miles of aquatherm blue pipe in various sizes from .-in. up to 24-in. for the expanded Hard Rock. “We ran around 700 feet of 24-inch pipe in about eight days,” he said.

In addition, about 3,000 ft of aquatherm green pipe, SDR 11 and SDR 7.4 MF, 2-in through 8-in., was used for the domestic water mains in the casino expansion.

Though not Ferguson’s biggest project to date (hospitals typically require the most pipe), it was more than they supplied during the massive renovation of the Hard Rock Stadium, home of the NFL’s Miami Dolphins. Hettich said his customers like PP-R pipe for its durability and longevity.

“You have data centers that want aquatherm because it’s not prone to leaking. If you have a leak, it could wipe out 5,000 computers,” he said. “The same philosophy falls over to gaming. If you have a leak in the casino and gaming goes down, the loss is astronomical. People in gaming want it.”

Thanks to the low weight of the polypropylene material, which is up to 70 percent lighter than comparable metal pipes, assembly teams can easily move and process even large pipes.

In total, around eleven kilometers of aquatherm blue pipe in various sizes was delivered for the Hard Rock project.

“I’ve been in construction for 30 years and I’ve never seen anything like that, and aquatherm was a big part of it. It exceeded all expectations.”
