EF Knapp State Airport Environmental Assessment, Bid, and Construction Phase Services

 

As a result of the American Recovery and Reinvestment Act (ARRA), the State of Vermont was presented with an opportunity to advance $6-million of improvements at the EF Knapp State Airport. Airport improvements included: parallel taxiway extensions, runway 5-23 reconstruction, terminal apron area reconstruction and expansion, and runway lighting and signage improvements.

To meet the aggressive deadlines established by the funding requirements, the Vermont Agency of Transportation (VTrans) had to devise a method to fast-track the NEPA clearance, complete the contract documents, prepare the front end documents, and bid and award the contract.

VTrans utilized DuBois & King to provide services typically provided from within the Agency. VTrans was able to satisfy ARRA requirements, fulfill its FAA obligations, and meet its own requirements for construction oversight by using D&K for resident engineer and inspector, and for construction administration services. This project delivery method was a first for the Agency.

DuBois & King provided services to fast-track the completion of the Environmental Assessment (EA) under the National Environmental Policy Act (NEPA). The Environmental Assessment was completed within 5 weeks. The FAA issued the FONSI 3 weeks later.

The project was the first to use FAA specifications and front end documents for a state aviation project; the first to use a consultant to prepare front end documents, advertise, distribute plans and specifications, review bids, recommend for award, and prepare the notice of award and notice to proceed; and a the first to use a consultant for full construction phase services, including resident engineering, inspection, and administration.

Burlington International Airport

 

The Burlington International Airport needed to expand its general aviation and cargo carrier area at the southern end of the airport, which would impact existing wetlands. DuBois & King was selected by the Airport to provide environmental services to locate and design a compensatory wetland site.

A 49-acre site along Muddy Brook in the City of South Burlington was selected by D&K in consultation with the US Army Corps of Engineers and the State Wetlands office for use as a compensatory wetland mitigation area. The site restored 4.9 acres of degraded upland habitat and 12.5 acres of degraded wetland habitat, and created 2.9 acres of marsh from existing upland. The mitigation site includes 21 acres of high quality forested wetland, shrub wetland, upland forest, and 1,200 lf of the Muddy Brook Corridor.

The site design was reviewed/approved by the FAA, US Army Corps of Engineers, and State Wetlands office. DuBois & King provided resident services during the construction phase of the project and provided monitoring/reporting over the five-year establishment period. Services include:

Site assessment
Wetland mitigation services
Construction phase services
Post-construction monitoring
