With just two months until scheduled completion, contractors at the Naval Air Station in Jacksonville, Fla., are putting finishing touches on the U.S. Navy’s largest hangar, which is being built to make room for five squadrons coming from Maine under the government’s Base Realignment and Closure program.
Mortenson Construction Co., Minneapolis, is the design-builder for the $127.7-million project under a multiple award construction contract with the Navy. The scope of work includes clearing more than 40 acres and demolishing base housing that occupied the site, decommissioning three storm water retention ponds and constructing a 275,000-sq-ft hangar, with fire-water storage tanks, 1.1 million sq ft of 14-in.-thick apron paving and a new 10-acre wet detention pond.
