Construction of the Marriott Atlanta Airport Getaway Hotel focused on two factors when building began: Finding an efficient boom pump for a restrictive site and receiving LEED certifi cation for efforts in green energy.

Construction of the 400,000-square-foot site started in September 2008. It was particularly difficult because the site was adjacent to another construction project. There were only two possible places to set up boom pumps: The first location was cramped because of construction for a monorail at the Atlanta Airport, and the second location required a versatile boom pump that could fit tightly between two buildings.

Because of the limited space to pour concrete, contractors from Brasfield & Gorrie, Kennesaw, Ga., chose Pioneer Concrete Pumping, Smyrna, Ga., as their concrete pump supplier. “The pumping company has reliable service and equipment, and has a superb record on past projects they’ve worked on with us,” says Ben Norton, senior project manager of Brasfield & Gorrie.

Every pour needed a strategy, according to Cory Postlewait, account representative for Pioneer. The pumps needed the ability to move over and under the monorail and between the two buildings. “We needed to be sure to get the most reach out of every boom for every pour. In some situations, we needed a boom to reach up and over a 12-foot structure,” says Postlewait.

To make construction more complicated, the hotel is octagonal in shape, which forced the boom pumps to work around the slab foundation in six phases, even forcing the pumps onto roadways.

All of Pioneer’s boom pumps were used at the construction site, but one in particular was considered the most valuable—a Putzmeister 63ZMeter. According to Postlewait, the 63Z pumped about 90% of the concrete. Although it is the largest of Pioneer’s boom pumps, their five-section Z-fold boom provided the versatility needed for the project. The pump’s 203-foot, 9-inch vertical reach was important when getting above structures.

The pump also helped with the other goal for the project—the effort to qualify for LEED certification. Postlewait says the pump maintained smooth and efficient pumping, completing most pours in less than three hours.

Other efforts toward LEED certification included onsite construction trash diversion and the use of recycled materials in the finish of the hotel, including the carpet and small amounts of recycled materials in the concrete.

After two years of construction, the hotel will be complete in summer 2010 and will open to the public at the end of 2010. Putzmeister America Inc. 800-884-7210.
