Hanscom Field Reconstruction of Taxiways E, M, & G
Hanscom, Bedford, MA | Massachusetts Port Authority
Hanscom Field is owned and operated by the Massachusetts Port Authority (Massport) as part of the network of regional airports servicing the Greater Boston area. The airport services a variety of users including: general aviation, corporate, commercial service and cargo aircraft. McFarland Johnson and Massport have a long-standing relationship that includes many successful projects at Hanscom Field. MJ was selected by Massport to provide design and construction administration services associated with the Taxiway E reconstruction project. During the design phase of Taxiway E, Massport was notified that they were eligible for additional funding through the American Recovery and Reinvestment Act (ARRA), also known as the economic stimulus program. The ARRA program included very tight scheduling requirements including the need to have bid results in hand within 120 calendar days from the date of notification of funding. MJ was entrusted to deliver an additional bid package for the reconstruction of Taxiways M & G within this timeframe.
Through careful coordination, diligent project management, and attention to detail, both projects were bid on time and within budget and allowed Massport to capture the available funds for both projects. The contract documents included the use of pavement reclamation techniques to grind, blend and re-utilize the existing asphalt pavements and base course materials a as the new pavement section base course. The projects also incorporated "warm asphalt" technologies to decrease the environmental footprint of the project. Warm-mix asphalt allows the producers of asphalt pavement materials to lower the temperatures at which the material is mixed and placed on the road. A reduction of approximately 50 degrees Fahrenheit was specified for the asphalt batching temperature, and a paraffin wax additive was utilized to provide the additional workability required at these lower temperatures. Such drastic reductions in asphalt batching and placement temperatures have the benefit of cutting fuel consumption at the asphalt plant and decreasing the production of greenhouse gases. Recycled asphalt was also specified for use in the batching process, further reducing the environmental impact associated with these projects.
These projects are evidence of not only the commitment that MJ provides to our clients for completing projects to the highest of quality standards, on time and within budget, but also for completing our projects in an environmentally responsible manner.
