RIGHt While full credit goes to the crew, advanced planning tools such as the floor installation analysis helped make things flow smoothly. This two-year project ended with only a very small punch list—the sign of a very successful operation! epoxy resins and other chemical compounds. "Those rooms needed Koster Vap I 2000," says Sacks, "but the kitchen was fine because our Poly-Crete system is designed to handle up to 99 percent RH." In the mechanical rooms, the CEI crew put down Koster Vap I 2000. Atop that they installed Elast-O-Coat Waterproofing Membrane, a 100 percent solids, two-part, elastomer-modified, high-build epoxy. The crew achieved 30 mils/762 microns (DFT) by using 1/4-inch (0.64 cm) v-notched squeegees. Fiberglass shreds were shot onto the epoxy using a chopper gun. Shreds were back rolled for additional crack reinforcement. It was quite a show when the crew shot the fiberglass. "We had half a dozen guys in Tyvek suits shooting fiberglass," says Gillman. "One guy with the trigger, two guys jockeying hoses to keep out of wet epoxy, two other guys on rollers to embed fibers into Elast-O-Coat, and one guy mixing. The fiberglass strands come on a big spool and the chopper gun pulls them through. Razors chop them and shoot them out of the gun. We had 100 to 200 feet (30.48 to 60.96 meters) of air hose hooked up to the compressor outside the mechanical room. Two guys were holding the hose in one hand and had their other hand on the fiberglass strands." The crew trowelled Shop Floor epoxy on a four-inch (10.16 cm) cove base around pads and perimeter. Dur-A-Glaze #4 Cove-Rez contains silica sand to help it hang on walls. The Dur-A-Glaze Shop Floor system was put down to 16 mils/406.4 microns (DFT) with a v-notched squeegee and back rolled. After a full broadcast of sand to excess, the process was repeated with a flat squeegee for the epoxy and rebroadcast of sand. Sand was swept and vacuumed and then back rolled and cross rolled. A final coat of Armor Top to 3 mils/76.2 microns (DFT) was applied by dipping and rolling and cross rolling with short nap rollers.

Not everybody likes hospital food, but this 9,900-square-foot (919.7 meter2) kitchen definitely needed a good floor. The crew attacked the chore in two phases, starting with a Dur-A-Flex Poly-Crete MDB system that is moisture tolerant and can go on seven-toten-day old concrete. "There was a lot of hand work involved," says Sneath. "We had to slope to some drains and grease traps and we formed a 6-inch (15.24 cm) cove base out of epoxy aggregate to install on the walls. The Poly-Crete MDB is installed with a ½-inch (1.27 cm) notched squeegee followed by back roll with texture roller and broadcasted with aggregate to rejection. This is followed by two pigmented topcoats of epoxy." Operating rooms and seclusion areas were next, 25 in all that covered about 15,000 square feet (1,393.55 m2) on various levels of the building. The crew organized themselves to do six rooms at a time, each of which took about seven days. The Koster Vap I 2000 for moisture went down first followed by a five-coat, flaked floor system with integral cove base. "The biggest challenge with these areas was the level of cleanliness and detail required," says Sacks. "There could be no areas that would harbor bacteria or dirt." SucceSSFul oPeration With hard work and attention to detail, the CEI crew finished the project on time. While full credit goes to the crew, advanced planning tools, such as floor installation analysis, helped make things flow smoothly. "Knowing as much as possible up front helps eliminate big surprises," Sneath says. "There are always little surprises, but you expect them." For Gillman, ramrodding CEI's first major new build project for HBE was a challenge, but he and his crew managed to complete this two-year project with a very small punch list, which they quickly dispatched. Now that's the sign of a successful operation! cP
