Y -- 8GEV BEAM ENCLOSURE CONNECTION Sol FESS-MI-55401-ARF due 111695. Contact A. Richard Farritor, 708/840-4611/Contracting Officer. 8GeV Beam Enclosure Booster Connection - Project No. 6-6-12. Project consists of the construction of the final 215 foot long segment of underground enclosure connecting two existing enclosure segments. Work includes earth retention systems of both sheet piling and soldier piles with lagging, 32'' deep excavations, demolition of existing underground concrete enclosures, pavement removal, support of existing underground utilities to be maintained throughout construction, settlement monitoring of existing structures, approximately 1000 C.Y. of cast in place concrete enclosures, setting of ten (10) Fermilab-furnished precast concrete enclosure elements (10''w x 8 1/2 7.5'1) weighing 36,000 pounds, placing of approximately 2000 tons of Fermilab-furnished steel shielding, underdrains, waterproofing, sump pumps, ventilation system, dehumidifier, electrical work, including convenience power, lighting and grounding systems, painting of enclosure walls and ceiling, floor sealing, hollow metal doors, frames, and hardware and site work including erosion control, road detour, hardstands, storm sewers and structures, underground piping extensions, communications ductbank, berms, final grading and seeding. A portion of the work, defined as Phase A must be accomplished during an accelerator shutdown period tentatively scheduled to begin in March, 1996, and last approximately 16 weeks. Award for the entire work scope will be issued as soon after receipt of bids as possible and pre-shutdown work including earth retention work, excavation and partial demolition is planned to commence in February.
