- Description
- The purpose of this Amendment is to add additional information for potential sources to consider, prior to expressing an interest in providing a response to a Request for Quotations that Reclamation proposes to issue. All sources are advised that Reclamation's contemplated RFQ will stipulate that Contractor shall complete six (6) BPT borings 30 to 95 feet deep; (6) BSB borings 30 to 95 feet deep; and (6) additional borings, 30 to 95 feet deep at the government's option. The drilling equipment furnished by Contractor shall consist of a Model AP-1000 drill rig manufactured by Drill Systems, Calgary, Alberta, Canada (403) 295-7676. The rig shall be equipped with an International Construction Equipment (ICE) Model 180 Diesel Pile Hammer. The hammer shall be equipped with a Gardner-Denver rotary blower supercharger Model No. 3PDR-9 connected to one of the inlet ports of the diesel pile hammer combustion chamber. The Becker Hammer drive casing outside diameter shall be 6.6 inches. The BPT soundings shall be advanced with a 6-5/8-inch O.D., 8-tooth crowd-crow-out, closed -end bit with a machined end plug for the purpose of collecting blow counts to specified depths and for subsequent tremmie backfilling. A ?-inch NPT T-fitting from the bounce chamber pressure gage, which is to allow for the connection of an electric transducer and automatic data collection system, shall be provided by the government. Contractor shall provide pullback force and displacement measurement equipment for Standard Penetration testing developed by GRL, Inc., for the Federal Highway Administration. The strain (force) transducers will be monitored by signal conditioning units and fed into a laptop computer. The displacement will be monitored with a string/tape extensometer/potentiometer. Contractor shall provide PDA equipment suitable for obtaining continuous data to estimate the energy transferred to the top of the Becker Hammer drive casing and to correct Nb30 for each one-foot drive interval. PDA measurements are to be taken with force and acceleration transducers on the drill string by an instrumented pope section with a Pile Dynamics, Inc. pile driving analyzer. Contractor shall provide equipment and labor to perform CAPWAP analyses, using the recorded PDA data from each respective BPT borehole sounding. CAPWAP analyses shall be presented within the report, including the rationale for selecting the BPT hole intervals for which the CAPWAP analyses are performed. Results from the CAPWAP analyses will be used in the conversion of Becker Hammer penetration resistance data into equivalent Standard Penetration Test (SPT) resistance N1 (60) values.
