NIGP 91216: Boring, Drilling, Testing, and Soundings, Including Concrete Coring

NIGP 91216 Boring, Drilling, Testing, and Soundings, Including Concrete Coring is an Item code that encompasses subsurface exploration, well installation, horizontal directional drilling, and specialized bore work performed for state and local agencies managing water infrastructure, transportation corridors, environmental remediation, and utility systems. Recent solicitations show state and local governments buying stock water well drilling and installation (Boulder County Parks and Open Space, RFP30026, due September 4, 2026, $350,000); geotechnical drilling and sampling for landslide remediation and highway design (Oregon DOT, multiple RFCQs through April–May 2026); directional boring and hand trenching for conduit placement (Pinellas County School District, ITB 26CD024, due June 12, 2026, approximately $250,000); production well design and construction (City of Palm Bay, RFP 30-RFP-26, due April 28, 2026); and jack-and-bore installation for utility relocation beneath railroads and expressways (Fort Valley Utility Commission, RFP for effluent pipe installation, due July 24, 2026). Issuing bodies span county parks departments, state departments of transportation, county and city public works and utilities divisions, school districts, utility commissions, and regional water authorities. Counties and cities in Florida, Georgia, Oregon, Colorado, Utah, and California have posted recent opportunities under this code.

Recent activity concentrates in the Southeast (Florida, Georgia) and Pacific Northwest (Oregon, California), with notable water infrastructure and highway/bridge projects. Boulder County Parks and Open Space issued a non-mandatory pre-proposal meeting for August 17, 2026 (RFP30026) for four stock water wells on agricultural properties with solar-powered infrastructure, requiring 100 percent performance and payment bonds. Oregon DOT released rebid RFCQ S-73000-00016742 for emergency geotechnical drilling at three landslide sites on Highway 227 in Jackson County, with bids due May 1, 2026, seeking hollow stem auger drilling, HQ wire-line rock coring, Standard Penetration Testing, and vibrating wire transducers across 540 feet of subsurface work. Fort Valley Utility Commission requested proposals for 4,000 linear feet of 20-inch fusible PVC effluent pipe installation using open-cut and jack-and-bore methods beneath a Norfolk Southern railroad, with a 40-foot launching pit and 15-foot receiving pit, proposals due July 24, 2026 (responses must come from entities pre-registered on the List of Proposers). Pinellas County School District issued an ITB for directional boring and hand trenching on an as-needed basis with a mandatory pre-bid conference May 28, 2026, requiring Florida Underground Utility Contractor licensure, 24-hour emergency response, and pricing on a per-linear-foot basis by conduit diameter and run length. City of Palm Bay's production well RFP requires four 17.4-inch diameter wells to 850 feet depth with geophysical logging, video logging, step-drawdown testing, and 8-hour constant rate discharge testing.
