E-MAIL: Frances B. Davidson, frances.b.davidson1@jsc.nasa.gov. NASA/JSC plans to issue a Request for Offers for the completion of repairs and modifications to the tunnel system and its utilities. The project includes the excavation, backfill, compaction, and site grading for the installation of two new tunnel exits. Installation of new electrical duct banks will require excavation, backfill, compaction, site grading and pavement replacement. Several new sump pumps will also be installed in the tunnel. Some of these installations will require installing discharge piping to existing manholes. The project will also include cast-in-place concrete construction of two new exit hatches, replacement of existing steel hatch covers with light-weight aluminum covers, waterproofing and concrete repair, installation of additional drainage sumps in the existing tunnel floor. Steps, ladders, and safety cages will also be required. Removal of abandoned communication cables and providing additional cable trays in certain areas is also included. The power distribution system will be reconfigured to relocate existing 12.47 kv cables to duct banks. Twenty-five Gaitronics handset units in Building 24 mechanical rooms will be added to the Gaitronics communications system. This project has a base bid and three additive alternates. Additive Alternate No. 1: Relocation of Feeders 4-6 and 5-6 from the tunnels to the duct banks, the connection of service to the Building 24 South Substation in the new duct bank, and the addition of new duct bank from Electrical Manhole No. 9D south to the east-west tunnel leading from Building 44. The duct bank includes the construction of new electric manholes, two bored road crossings, and asphalt pavement repair in one parking lot. Additive Alternate No. 2: At the completion of construction of Phase III, the contractor will be responsible for detailed cleaning of the tunnel. This includes the removal of discarded construction debris, cleaning of utility surfaces with damp rags and cleaning of the entire tunnel using a HEPA-VAC. There is asbestos in the dust on the tunnel floor, therefore, no cleaning procedures shall be used that produces large amounts of dust. Additive Alternate No 3: A new run of duct banks from the north side of Avenue B through Electric Manhole No. 11L and south to Electric Manhole 105 will be installed. This includes all work to install the duct bank with one bored road crossing and new electric manholes. No cable will be installed in this new section of duct bank.
