NIGP 76020: Earth Boring Machines

NIGP 76020 Earth Boring Machines, an Item code, covers directional boring and horizontal directional drilling (HDD) services for underground utility installation, extension, maintenance, and repair. State and local governments procure this work on as-needed and project bases for water, sewer, natural gas, electrical, and telecommunications infrastructure. Recent solicitations show municipalities and regional authorities engaging contractors to bore under roadways, taxiways, and intersections using unit-price and fixed-price contracting structures. Issuing bodies include city procurement offices (Milton, Florida; Marietta, Georgia), county transportation authorities (Santa Clara County, California), and airport authorities (Draughon-Miller Central Texas Regional Airport in Bell County, Texas). Contractors must hold state-specific underground utility and excavation licenses, carry commercial general liability and contractors pollution liability insurance, and comply with bonding requirements scaled to project value. The work demands bore path and profile documentation, frac-out prevention planning, traffic control coordination, and as-built verification.

Recent activity concentrates in Florida, Georgia, Texas, and California. The City of Milton, Florida issued ITB 2026.05 for directional boring services on an as-needed purchase-order basis with bids due July 22, 2026, requiring fixed unit pricing per linear foot by pipe diameter and material type (steel, HDPE, PVC ranging two to twelve inches) and mandatory 24-hour emergency response capability. Draughon-Miller Central Texas Regional Airport solicited bids under BID360326 for approximately 336 linear feet of steel encasement installation under a taxiway with an engineer's estimate of $135,000 and a 45-day completion window, bids due August 5, 2026. The City of Marietta, Georgia's roundabout construction project (RFB 26-53444, bids due June 26, 2026) incorporated utility bore and relocation work as a component of broader infrastructure construction, though that solicitation carried a Georgia GDOT certification eligibility restriction. Santa Clara County's pavement rehabilitation project (ITBRDAFY260694, May 21, 2026) did not emphasize boring as a primary scope but included related underground work.
