Amendment 2

ITEM DESCRIPTION AND SPECIFICATIONS

For the procurement of (1) a new drill rig with dual sonic and rotary coring dill heads and

(2) associated drilling equipment all to be used by the Columbia-Pacific Northwest Interior Region 9 Regional Drill Crew, Boise, Idaho.

1. Introduction This document provides the detailed information needed for the acquisition of a new sonic drill rig and associated drilling equipment to be purchased for the Bureau of Reclamation’s (Reclamation) Columbia-Pacific Northwest (CPN) Drill Crew inventory.

2. Objective Sub-surface explorations within and around Reclamation facilities are typically accomplished through drilling programs. Drilling programs—written by technical experts from Reclamation’s Technical Service Center (TSC)—are designed to ensure all appropriate data is collected in the field to fully support Reclamation’s mission. Most drilling programs include in-situ soil sampling, rock coring, instrumentation installation, and in-situ material testing. The TCS requires no more than 6.7 PSI ground pressure when working on certain roads or in sensitive habitat areas.

Reclamation has planned projects in remote locations, including overseas, that necessitates shipping the rig in a 20’ shipping container. It will also be flown in to remote sites with a helicopter.

By following the drilling methods described in ASTM D6914-04, sonic drill rig will collect continuous soil core efficiently and quickly regardless of material type or size. This benefit allows a sonic rig the ability to drill through and collect samples of all the various zoned material within Reclamation’s earthen embankment dams.

The sonic drill rig will also core into, and collect samples of, in-situ bedrock which provides invaluable information regarding the foundation and abutments of dams. The ability to switch between soil sampling and rock coring without moving the drill rig off the drill hole is dependent on the dual drilling capacity of the drill head. A sonic drill head that can drill into and sample both soil and rock material will meet most all of Reclamation’s requirements for drilling programs.

The sonic drill rig has the capabilities of collecting samples of earthen materials continuously without the need for introducing drilling fluids in the process. The use of drilling fluids within earthen embankment dams is a prohibited practice as pressurized fluids increase the potential for hydraulic fracturing of the surrounding embankment material. Because drilling fluids are not needed, a sonic drill rig can safely drill through Reclamation’s earthen embankment dams, including the dam’s core, while adhering to Reclamation’s standard Guidelines for Drilling and Sampling in Embankment Dams [2].
