This is Amendment Number 01 to the Scattered Site Well Drilling project (CA22-D46 / EDO-295-D46) issued by the California Area Indian Health Service on June 17, 2026. The amendment modifies the original bidding documents dated May 2026 and must be acknowledged on Standard Form 1442 to avoid bidder disqualification.
The amendment adds one new bid item and corresponding specification language to the contract documents. Item 12, "14-inch Steel Conductor Casing - Optional," has been added to the bid form (Document C-410) with an estimated quantity of 60 vertical feet. The payment basis includes drilling, reaming, casing, centralizers, drive shoes, fittings and accessories, formation sampling, labor, equipment, installation, and backfilling. A new specification section (33 21 00 – Individual Water Supply Wells, part 3.3 DRILLING, item F) requires the contractor to install steel conductor casing if determined necessary based on encountered geologic formations and to notify the Engineer if such casing is justified. The bid form contains 12 total items covering well drilling services, including mobilization/demobilization, drilling, various casing types, grouting, filter pack, well development, test pumping, disinfection, pump equipment, and drop pipe installation, with quantities measured in vertical feet, lump sum, hours, or each as applicable.
