Hotel Project Seeking LEED® Certification
Hotel Project Seeking LEED® CertificationPutzmeister boom pumps place 20,000 cubic yards on restrictive job site
STURTEVANT, WI (October 22, 2009) – Brasfield & Gorrie, the general contractor of The Marriott Atlanta Airport Getaway Hotel at the Georgia International Convention Center (GICC), is showcasing its effort in being “green” by seeking Leadership in Energy and Environmental Design (LEED®) certification of the project. In addition, Pioneer Concrete Pumping’s (Pioneer) Putzmeister boom pumps are showcasing their maneuverability of pumping and placing concrete for the 70-foot (21m) high structure.
What it Takes
“A lot of the projects we’ve worked on in the past few years are LEED certified,” says Ben Norton, senior project manager of Brasfield & Gorrie. “Several of the projects have achieved different levels of certification. We think it’s important, no matter what the job is, to find a way to be greener in our construction processes.”
According to the U.S. Green Building council, LEED is an internationally recognized green building certification system which provides third party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.
“We were provided a concise framework that allowed us to identify and implement practical and measurable green building design, construction, operation and maintenance solutions for the project,” adds Norton. Norton says his team has been doing a number of things to strive for the LEED certification.
“The main component of our effort towards LEED certification has been on-site construction trash waste diversion,” explains Norton. “Basically we sort out the different materials so they can be recycled. Materials are sorted by metals, wood and dry wall. We’re able to tell how much we’ve recycled by a report the waste company submits to us every month.
“We’ve tried to incorporate recycled material into as many of the finished materials for the hotel as well, such as carpet. There is also a small amount of recycle content in the concrete being pumped and placed.”
A voluntary certification program, LEED certification focuses on key areas, including:
• The sustainability of the job site
• Water efficiency
• Energy and atmosphere
• Materials and resources
• Indoor environmental quality
• Locations and linkages
• Awareness and education
• Innovation in design
• Regional priority
Efficient on a Restrictive Job Site
Breaking ground on the 400,000 square foot (37,161m2) site in September 2008, Brasfield & Gorrie chose Pioneer as their concrete pump supplier.
“The pumping company has reliable service and equipment, and has a superb track record on past projects they’ve worked on with us,” comments Norton.
Because of the extremely restrictive job site, right next to another construction project, Norton and his team needed versatile pumps to get the job done.
“There were only a few set locations where we could set up the boom pumps due to two construction projects being conducted side by side,” says Norton. “At one of the setup locations, a monorail for the Atlanta airport was being constructed in the vicinity of where we needed to place concrete for the hotel. And at the other location, the booms needed to set up snug in between two buildings.
We needed to make sure we were using boom pumps that had the maneuverability to navigate over and under the monorail, and in between the two buildings.” Pioneer’s fleet of boom pumps, ranging from the 20Z- to the 63Z-Meter were on site to place the 20,000 cubic yards (15,291m3) of concrete throughout the project. In addition to the boom pumps, the pumping company also had their City Pump CP 1409H on site for miscellaneous concrete placements.
“With every pour, we strategized to determine what would be the best way to set up the pump and which pump to use,” notes Cory Postlewait, account representative for Pioneer. “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 (4m) structure.”
The hotel rises seven levels high, with an additional three levels sitting beside the hotel.
Because the hotel is being constructed in an octagon-like shape, the boom pumps needed to work around the hotel’s slab foundation to place the concrete in six phases, sometimes forcing the pumps to set up on public roads.
Each of the levels of the hotel ranged from about 1,000 to 1,800 cubic yards of concrete (765 to 1,376m3) with about 300 to 400 cubic yards (229 to 306m3) of concrete on average per pour.
Although all of the pumping company’s boom pumps were used on site, it was the company’s 63Z-Meter that was the workhorse on the project. “The 63Z did about 90 percent of the concrete pumping on this project,”
says Postlewait. “Even though this boom pump has the largest footprint of all of our boom pumps, it was still able to set up easily in the confined environment.
“It’s five-section Z-Fold boom configuration really kept the project moving with its ease of flexibility to maneuver in the most unique environments. And the 63Z’s 203-foot, nine-inch (62.10m) vertical reach was crucial when reaching above the obstructing structure to the point of placement.”
In addition to the boom’s reach the pump’s output capability also came into play.
“It pumped on average up to 100 to 120 cubic yards per hour (77 to 92 m3/hr),” explains Postlewait. “The pump was able to maintain its smooth and efficient pumping even when set up in the restrictive environment. Most pours were completed in less than three hours.”
The hotel is set to be complete in summer 2010 with it open for the public in late 2010.
