incorporating comments and suggestions from local authorities in the initial design, the team minimized any changes needed at the permitting stage, which was essential in keeping to the necessary schedule and avoiding unnecessary costs. chAllenges MeT AnD surMounTeD The size, scope and time constraints were challenging, but when the project began, new and unanticipated problems emerged. A month-long hold due to hurricanes was not exactly unexpected in Florida, but that delay made it hard to schedule the project. Conflicts with underground utilities and problems with local work force productivity also proved to be stumbling blocks. In addition, the project floor plan had to be reprogrammed. All of these challenges were met without exceeding either time or cost requirements. Mortenson did anticipate setbacks and had mechanisms in place to deal with them as they arose. One important factor was the use of Building Information Modeling (BIM) and creating a threedimensional model during the design phase. This allowed the designers to coordinate the large, complex structure with correspondingly complicated utilities and mechanical and electrical systems before construction began. With the designers, contractors and subcontractors sharing information electronically, the team could spot conflicts and correct the design before construction began, all without having to wait for shop drawings to be drawn, redrawn and distributed. The Mortenson team also kept schedules electronically, allowing the team to update them as changes occurred while keeping workers coordinated. In addition to the electronic coordination, the team used the model to prefabricate much of the mechanical piping and ductwork off site. Pipe tees and elbows were pre-welded and valves were fitted in the fabrication shop. That not only saved time, but provided higher quality products as well. During the construction phase, the Nav y awarded a contract for a small building to another contractor. This building fell within the footprint of the Mortenson team’s work area. Continuing with the established cooperative team approach, the design-build team integrated the contractor and his work into their sequence of operations so that the smaller building could be completed without incident. MIssIon coMpleTe As with any highly successful design-build project, the Jacksonville NAS Type II Hangar and Aircraft Parking Apron was completed on time and within budget and to the owner’s complete satisfaction. As the owner, the Navy appreciated being involved in the process. The design-build team accommodated the Navy’s specific wishes and needs and was available to the owner as needed. The Navy lauded the Mortenson team for “going the extra mile” in creating the best end product for which it could hope. Recognizing this, the 2011 Design-Build Awards jury honored the team with a National Design-Build Award in the Transportation category (see page 33). / snApshoT project: Jacksonville NAS Type II Hangar and Aircraft Parking Apron location: Naval Air Station (NAS), Jacksonville, Fla. owner: U.S. Navy Design-Builder: M.
