Description

ACTION CODE: P PART: U.S. GOVERNMENT PROCUREMENTS SUBPART: SERVICES CLASSCODE: E -- Purchase of Structures and Facilities OFFADD: U.S. Army Corps of Engineers, Engineering and Support Center, Huntsville, 4820 University Square, Huntsville, AL 35816-1822 SUBJECT: E- PURCHASE OF STRUCTURES AND FACILITIES, FT IRWIN, CA SOL: DACA87-01-R-0051 DUE: 60 Days after the RFP issue date POC: Tonju Butler, 256-895-1166 DESCRIPTION: The U.S. Army Engineering and Support Center, Huntsville, Alabama in support of Fort Irwin intends to privatize its liquified petroleum gas (LPG) tank farms and distribution, water treatment and distribution, and wastewater collection and treatment systems. Fort Irwin is a remote post located in the Mojave Desert approximately 35 miles from Barstow, California. Privatization is the transfer of ownership, operation & maintenance, repair, and improvements of Army owned systems to a non-Federal entity, and the subsequent acquisition of the utility distribution services from the new owners of the systems. This privatization does not include the LPG commodity and does not supplant existing commodity contracts. The Government will retain liability of any pre-existing environmental conditions. The conveyance of the utility distribution systems is authorized and conducted under 10 U.S.C. 2688. The conveyance will transfer all rights, title, and interest of the United States Government in and to the utility distribution systems. The conveyance will not include any land. The contract for the acquisition of utility distribution service will be for a term of 50 years. SYNOPSIS: LPG DISTRIBUTION SYSTEM. The LPG distribution system at Fort Irwin consists of approximately 197,000 linear feet of pipe, not including the service line, ranging from less than 2 inches to 10-inch pipe. The system serves approximately 1220 buildings, has 159 main valves, 12 meters, 15 main regulators, and contains nine (9) 30,000-gallon storage tanks and 3 vaporizers operating from two tank farms. The original distribution system was installed in the late 1950s. A complete change out of distribution and service line was completed during the 1985-1987 timeframe with the exception of approximately four buildings still containing steel pipe. Polyethylene has been added to the system from 1985 to the present. The polyethylene system consists of Drisco 3406, Plexco 2406, and Polaris 2406. The polyethylene was joined by electro fusion, Lyco Permaset, butt fusion, saddle fusion, and socket fusion. WATER DISTRIBUTION SYSTEM. The water distribution system consists of approximately 405,000 LF of distribution line made primarily of asbestos cement (AC) and poly vinyl chloride (PVC) pipe, serving two separate distribution systems, one supplying raw water to the cantonment area for non-potable uses (approximately 390,700LF), another conveys treated groundwater for drinking water needs (approximately 14,300LF). Approximately 12 groundwater wells withdraw groundwater from three separate basins, Langford, Bicycle, and Irwin. Two booster stations bring the raw water from the Bicycle and Langford basins and Irwin basin lies underneath the cantonment area. Raw water is then transferred into one of the 4 distribution tanks. A single well operating at 450 gpm is used to supply a reverse osmosis (RO) plant utilizing specific membranes (Cellulose Acetate) that treat for elevated levels of fluoride. Filtration pretreatment, pH adjustment, and chemical sequester is necessary to optimize fluoride removal prior to RO treatment. The water is pressurized from 200 to 300 psi prior to entering the RO elements. Post-RO treatment includes a scrubber to reduce the carbon dioxide and raise the pH. Further pH adjustment is supplied by adding sodium silicate. Zinc phosphate is added for corrosion control. Finally, chlorine is added just prior to discharge into the RO potable water system through a system of pressure tanks. WASTEWATER COLLECTION AND TREATMENT SYSTEM. The wastewater system consists of approximately 228,000 LF of collection pipe, lift stations, wastewater treatment plant (headworks, pretreatment, oxidation ditch, secondary clarifiers, chlorination), effluent evaporation/percolation ponds, and irrigation discharge originally constructed in 1955. Subsequent improvements have increased the plant capacity to 2.0 MGD. Average plant influent is 1.3 MGD with average biological oxygen demand (BOD) of 200mg/L and TSS nearly 240 mg/l over a monthly operating period. Effluent BOD was 10 mg/l during the same period with waste discharge requirements in place that stipulate a maximum unfiltered BOD limit of 30 mg/l for effluent available for percolation into the surrounding groundwater basins. Plant effluent must comply with state reclamation requirements, including coliform organism limits from bacteriological results. The water and wastewater systems shall be considered as one system for contract award purposes. All responsible sources may respond to this synopsis, and all such responses will be considered by the agency. It is anticipated that the request for proposals (RFP) will be available on or about 8 September 2001 electronically through the Internet at www.hnd.usace.army.mil/contract. The following North American Industry Classification System Code applies: 22112, 22122, 22131.
