Installers faced material handling challenges with the two-tower Bridgewater Lofts project in Minneapolis, completed in September.
The glazed project includes a seven-story tower and a 10-story tower, both featuring heavy pre-glazed units, says Bill John, president of Minneapolis-based InterClad, the contract glazier.
“One of our bigger challenges was unloading all of the windows,” John says. “They are pretty good sized pre-glazed units that weight 300 to 400 pounds. At the end of the day, [our installers] were pretty worn out after handling those large units individually.”
InterClad had to carefully coordinate with the other construction trades to ensure installers would have enough space onsite to unload and house the large pre-glazed curtain wall units, the 810 series from Efco Corp., a Pella company, of Monett, Mo. “We had to figure out a way to unload loose units, and then develop a plan for what to do with them once they’re unpacked,” John says.
“It took us awhile to get a system in place with the other trades [while working on the seven-story building] but refined things by the time we did the 10-story.”
The project also features Efco’s 5900 inside glazed curtain wall system and its Terra Stile doors for the balconies. The ample glazing provides residents with sweeping views of the Minneapolis skyline and the Mississippi River.
Designers from Oertel Architects in St. Paul, Minn., specified low-emissivity glass for all units, using a gray tint on the seven-story building and a blue tint on the 10-story building. Viracon of Owatonna, Minn., was the glass fabricator.
JE Dunn Construction of Des Moines was the general contractor.
