Taxiway Whiskey Repair Joint Base Andrews

The USACE-Baltimore District has been tasked to solicit for and award construction services for the repair of Taxiway Whiskey Phase Three at JBA. • The project consists of the construction of the Third Phase of a four phased project replacing an existing deteriorated taxiway without interrupting the airfield mission. This Phase will be aligned with Phases I and II “as built” conditions. The contract will include revising parking rows on the West Ramp, match existing conditions and revise striping plans accordingly. The contractor will be required to prepare at least two or potentially more “mix designs” to identify different sources of “fly ash” to insure sufficient quantities to complete the project. The RFP for the construction contract will request the proposals to detail their plan to handle the approval requirements of the concrete mix design. • Structures penetrating Paver Compacted Concrete (PCC) pavements are typically isolated by the use of expansion joint materials. Unsuitable soil removal is necessary in significant quantities. Relocation and/or moving sub-drain manholes will be part of the contract scope. Provision and installation of proprietary controllers will be required foradding lights to the line circuits and continue operation of the SMGCS and ALCMS systems. The proposed contract execution schedule will be condensed and strictly enforced. • Constant coordination with several authorities is a pre-requisite for the safety and security at the airfield and inclusion of planned as well as un-expected “ramp freezes” will require close attention to accurate and constantly updated schedules to assure on time delivery of the project. • The contractor must supply all necessary security personnel, utilities, transportation and sediment and erosion controls as necessary for the successful completion of this project. The contractor will comply with all security and operational requirements of the Air Force Operational Command (i.e. “ramp freezes”, “dig permits”, etc.)
