NIGP 91460: Millwright

NIGP 91460 Millwright, an Item code, covers building systems installation, replacement, and repair work that state and local governments solicit across mechanical, electrical, structural, and infrastructure trades. Recent solicitations show millwrights performing HVAC equipment replacement, roof repairs and replacements, fire suppression and alarm system installation, electrical infrastructure upgrades, sewer and potable water line replacement, elevator modernization, bridge and pedestrian overpass renovation, building remodeling and interior finish work, and structural repairs at correctional facilities, behavioral health centers, and campuses.

Washington State dominates recent activity under this code, with the Department of Enterprise Services (DES) procuring on behalf of community colleges, state agencies, and correctional facilities across the state. Representative opportunities include Bellevue College's replacement of five water source heat pumps at Building R (sealed bid due June 16, 2026), Skagit Valley College's Nelson Hall HVAC equipment replacement (sealed bid due June 18, 2026), the Washington Department of Corrections' roof replacement at the Washington Corrections Center for Women covering six buildings totaling 64,384 square feet (sealed bid due June 9, 2026), Lower Columbia College's renovation of five buildings with mechanical, electrical, and structural work (sealed bid due June 23, 2026, with estimated cost $1.2 million to $1.4 million), and Tacoma Community College's storm sewer improvements including CIPP installation and manhole construction (sealed bid due June 16, 2026, with estimated cost $395,000 to $435,000). One procurement outside Washington—DeKalb County's reconstruction of the DeKalb Tennis Center including IT and low-voltage infrastructure (ITB due July 13, 2026)—appears in the dataset. Washington prevailing wage requirements, 15 percent apprenticeship utilization mandates, and voluntary diverse business goals (10% MBE, 6% WBE, 5% SBE/PWSBE, 5% veteran) are standard across most sealed-bid procurements. Bid guarantees of 5 percent and payment and performance bonds at 100 percent of contract value plus sales tax are typical; estimated contract values across representative opportunities range from $290,000 to $7.66 million.
