The small business size standard applicable to the proposed acquisition is 500 employees. The selected Subcontractor shall provide well drilling services to assist LLNL in environmental restoration of its two CERCLA/SARA sites, the Livermore Site and Site 300. Under LLNL direction, the selected subcontractor shall assist LLNL in its hydrogeologic investigations to determine the hydrogeologic characteristics affecting the water-bearing and vadose zones and to determine the fate and transport of the environmental contaminants. The selected Subcontractor shall provide personnel, equipment and material to drill various rotary (air, mud, and/or water mist) and hollow stem auger boreholes for sampling and coring of sediment and rocks. This includes the completion and development of piezometers, single and multi-level and/or multi-screened monitor wells and extraction/injection wells. Installation of downhole systems to include packers, pumps and pumping systems, pressure transducers, and sampling systems in the wells may also be required. Geologic materials to be drilled are unconsolidated or consolidated gravel, sand, silt, clay, sandstones, siltstones, mudstones, and conglomerates. Depths of boreholes and wells will range up to 500 feet. Unstable hole conditions, such as flowing sands, slow and difficult drilling conditions due to hard rock units, and unpredictable ground water pressure have been encountered in previous drilling efforts at the sites. The selected Subcontractor shall be capable of supplying the following drill rigs and personnel: Four TH60/RO300 or equivalent drilling rigs equipped for all conventional drilling methods to include air, mud, and/or water mist rotary and wireline coring for depths up to 500 feet. An additional capability to utilize hollow-stem augering must be available with the TH60 rigs. Each rig must have 500 feet of HQ/94 mm rod; the TH60 must also have 100 feet of auger flights. Four CME-750 or Failing F-10 or equivalent auger drilling rigs are required for depths of 200 fee or less. Each drill rig shall be supported by an independent grout plant, a mobile tanker, and a 1,000 gallon water tank. Eight lead drillers, each with 5 years of documented drilling experience, with 2 years as a lead driller or equivalent are required. The selected subcontractor shall also maintain a fully equipped office capable of supplying drill rig service and supplies. Response time from this office to the drilling site must be within twenty-four hours. Interested firms should respond with a description of qualifications with respect to the foregoing. Responses are requested only from firms qualifying as a small business with respect to the small business standard specified. Firms responding to this announcement which fail to provide the required information will not be considered further. Those firms deemed to be potentially qualified by the University will receive information regarding additional minimum qualifications. Responses are required on or before January 12, 1996.
