Drilling - CA BR NCAO SHAS(1) UPPER VISTA HOUSE ROAD

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the "DRILLING – CA BR NCAO SHAS(1) UPPER VISTA HOUSE ROAD" opportunity.

• Drill Rig Type: A drill type producing the same results as an auger is acceptable. The 6-inch diameter constraint must be met due to environmental hole size limitations. The drilling is intended for sample collection of approximately 50 lbs or 3/4 of a 5-gallon bucket.
• Track-Mounted Rigs: Track-mounted drill rigs are acceptable if they are of sufficient size to meet the requirements for drilling a 6-inch boring to a 5 ft depth through an estimated 6-inch asphalt depth and fill soil. The distance between boreholes is short enough that a track-mounted vehicle can drive between locations without needing to be loaded onto a trailer.

This Q&A clarifies equipment specifications and acceptable drill rig types, potentially impacting how bidders prepare their technical proposals.
