- Description
- Subcontract Description 116-N &184-N Explosive Demolition: Washington Closure Hanford (WCH) is seeking qualified subcontractors to provide demolition services to the River Corridor Closure. WCH is a prime contractor to the Department of Energy at Richland WA. WCH intends to award a minimum of two master agreements for explosive demolition services to support the RCC contract. WCH strongly encourages small businesses to participate and encourages teaming arrangements to meet the qualification criteria. WCH will determine (following review of the prequalification questionnaires) if the RFP will be set- aside for small businesses. Description of Work: The 116-N Stack and 184-N Powerhouse are located within the Hanford Site in the 100-N Area on the south bank of the Columbia River. Approximately 38 river miles upstream and 32 road miles from the city of Richland, in the southeastern corner of Washington state. 116-N: The 116-N Exhaust Air Stack (also called the Ventilation Stack) is a reinforced, monolithic, 69.5-m (228-ft) tall concrete structure that discharges ventilation exhaust to the atmosphere. It stands on an octangular-shaped below-grade base that measures 1.4-m (4.5-ft) in height and 10.2-m (33.5-ft) across. Top of stack is 61-m (200-ft) above grade. It is fed by a below-grade air exhaust tunnel that originates in the 117-N Exhaust Air Filter House. SUBCONTRACTOR shall be responsible for explosive demolition of the above-grade portion of the stack to include mobilization, dust and fragment projectile controls, drilling, falling the stack to a predetermined location, waste handling (excluding demolition rubble), demobilization, and other work necessary to demolish the 116-N in accordance with this contract. The CONTRACTOR will remove demolition rubble. 184-N: The 184-N consists of 4 attached structures; the 184 N Power House, the 184 NA Power House annex, the 184-NE compressed gas sheds, and the 184 NF chemical injection pump room. The 184 N Power House is a 34 m by 29 m by 21 m (112 ft by 96 ft by 70 ft) reinforced-concrete and structural steel building with channeled steel siding on the above-grade portions of the facility. There is a steel stack 21-m (70-ft) in height from the 17-m (56-ft) roof level. The facility housed a 15,000 kilowatt turbine generator that was driven by reactor generated steam or by a 575,000 Btu/hr boiler contained in the facility or by associated auxiliary equipment, air compressors, and compressed air receivers. Chemicals used for water quality control were stored in the facility, and contamination of the facility occurred from pump/equipment leaks. There is an adjacent facility approximately 15-m (50-ft) to the west. The 184 NA Power House annex is a 418.5 m2 (4,500 ft2) metal on metal frame building that housed two boilers serving as backups to the main boiler in the 184 N Facility. The structure shares a common wall with the 184 N Building on the west side. The boiler steam drums and piping received radioactive contamination from recirculated reactor secondary system water. East of the 184-NA is an associated steel stack that extends from grade to a height of approximately 24-m (80-ft). There is an adjacent active power line approximately 13-m (40-ft) east of the stack. The 184-NE compressed gas sheds consist of two small sheds each approximately 7-m2 (75-ft2) used to store compressed gas cylinders. Gas piping ran from the gas cylinders inside the sheds into the 184-N Power House. The sheds share a common wall with the 184 N Power House and are located on the south side of 184-N. The 184 NF chemical injection pump is within an approximately 9-m2 (96-ft2) pre engineered, single story steel frame building with metal siding and roofing. The facility housed the aqueous ammonia injection system that injected ammonia for water quality into the 109 N Facility?s secondary water system. SUBCONTRACTOR shall be responsible for building implosion, felling the stacks, fracturing concrete foundations and pedestals, and large component size reduction of the 184-N, to include mobilization, dust and fragment projectile controls, drilling, waste handling (excluding demolition rubble), demobilization, and other work necessary to implode the 184-N, fell the stacks, size reduce specified components, and fracture heavy concrete material into no larger than 0.9m (3ft) in dimension in accordance with this contract. The CONTRACTOR will remove demolition rubble. ::: Construction drawings for 116-N and 184-N will be provided as part of the subcontract documents. The primary pay item within the Subcontract will be lump sum. The subcontractor will be expected to provide a full-time on-site site superintendent, a full-time on-site health and safety/IH representative, and a project manager. The subcontractor will also be expected to have engineering resources available. PLEASE SEE 'WWW.WASHINGTONCLOSURE.COM/PROCURE/90-DAY.HTML' FOR PRE-QUAL QUESTIONAIRE AND DETAILED CONTACT INFORMATION.
