POC: Dennis G. McGrath (914-641-2818). The schedule for procurement of drilling services as originally published in a notice on January 4, 1996 and indefinitely delayed in a notice published on January 23, 1996 has now been finalized. Sealed Bids for the drilling and sampling of sixty-three (63) soil borings; the drilling, sampling and installation of sixteen (16) monitoring wells; the excavation of six (6) test pits; installation of one (1) geoprobe groundwater sample point; and the performance of a step drawdown and 72-hour pumping test at the Li Tungsten Site, a Superfund (NPL) hazardous waste site in Glen Cove, Nassau County New York, will be received by the ENGINEER, Malcolm Pirnie, Inc., 104 Corporate Park Drive, White Plains, NY 10602, until 2:00 p.m. local time on Tuesday, March 5, 1996 at which time and place, the bids will be privately opened. Bids received after the stated date and time will not be considered consistent with the application of FAR/EPAAR provisions. Bids received through the mail shall be made in accordance with FAR 52.214-7 and will be accepted by the Engineer in accordance with FAR 52.214-7. FAXED Bids will not be accepted. A Mandatory prebid site visit will be conducted at 11:00 AM on Thursday, February 15, 1996. Directions to the site are contained in the Bid Documents. Forty three (43) soil borings will be drilled and sampled around suspected source areas to a average depth of 10 feet. At each soil boring location, split-spoon samples will be collected from the ground surface to the specified depth, using ASTM Standard D 1586.84. Twenty (20) soil borings will be advanced for the purpose of down hole gamma logging to be performed by the ENGINEER. These soil borings will be advanced to 15 feet and a 2.5 inch diameter hollow PVC pipe, capped at the end will be temporarily inserted into the borehole by the SUBCONTRACTOR to facilitate the logging. After gamma logging is completed, the borehole will be grouted by the SUBCONTRACTOR. Nine (9) shallow and seven (7) deep monitoring wells will be installed in the overburden material. It is anticipated that the shallow wells will be approximately 25 feet deep and the deep wells will be approximately 100 feet deep. The wells will consist of a 10 feet length of four-inch diameter Schedule 40 PVC screen and casing. Properly sized gravel pack will be installed to two feet above the screen. A two foot thick bentonite seal will be installed on top of the gravel pack and cement bentonite slurry will be tremied to the surface. A six-inch diameter steel outer protective casing, with locking cap and vent hole will be installed over each well. Test pits will be excavated to provide detailed information on the vertical limits of the buried waste in an on-site disposal area and to collect soil samples for chemical and radiological analysis. The backhoe will excavate the test pit in one foot lifts of approximately two feet wide by ten feet long. Samples for laboratory analysis will be collected by the ENGINEER directly from the backhoe bucket. One soil boring will be advanced by the SUBCONTRACTOR for the purpose of installing a geoprobe sampling point. As an alternative, a separate boring may be drilled adjacent to the geoprobe location for sample collection. At this location, continuous split-spoon soil samples will be collected from the ground surface to the water table. The geoprobe will be hydraulically driven no more than five feet into the saturated zone. The ENGINEER shall be responsible for the sample collection. An aquifer test will be conducted by the SUBCONTRACTOR on one monitoring well. The aquifer test will include a step drawdown pumping test, followed by a 72-hour constant rate pumping test.
