Colorado's U.S. 6 Closed for Bridge Demolitions.
The Colorado Dept. of Transportation closed Denver's U.S. 6 freeway on the weekend of Feb. 14 to demolish the Knox Court Bridge and part of the Federal Boulevard Bridge over U.S. 6. During the full closure, crews from contractor Edward Kraemer & Sons Inc., Castle Rock, Colo., completed 20 nights' worth of work in 72 hours. Tasks also included a lane shift to allow for additional bridge work, says Kevin Sullivan, CDOT project director. The $98-million project will replace six obsolete bridges on U.S. 6 between Knox Court and Interstate 25 and improve traffic movement in the I-25 and U.S. 6 interchange. The closure marked the start of construction, which is scheduled to be complete in September 2015. The project designer is Felsburg Holt & Ullevig, Centennial, Colo.
Building Exceeds Performance Goals Guaranteed by Team
The 209,000-sq-ft Federal Center South Building 1202 for the Army Corps of Engineers in Seattle has surpassed contractual energy-use targets promised by its performance-based design-build team, freeing $330,000 in fees held back by the U.S. General Services Administration. GSA pioneered the proof-of-performance twist at the fast-tracked project, which opened last year. Led by Sellen Construction Co., with ZGF Architects and WSP/Built Ecology, the team also developed the building's post-occupancy measurement and verification program. Part of GSA's Design Excellence program, it is operating in the top 1% of similarly sized U.S. office buildings, says ZGF.
Big Auction Sets Online Record
The world's largest auction of heavy equipment, conducted by Ritchie Bros. on Feb. 17-22, set records for online sales, which made up about 33% of $166 million in gross proceeds. The annual auction featured more than 8,800 lots. The average price per lot was up slightly since 2013, to $18,864, and 29% of sales went overseas. Sales manager Steve Kriebel says inventory was lower than in recent years, but average sales prices were higher.
