NIGP 75052: Flexible Base

NIGP 75052 Flexible Base, an Item code, encompasses supply contracts for base-course road materials that state and local transportation and public works departments procure for pavement rehabilitation, maintenance, and new construction. Recent solicitations show municipalities and counties buying hot mix asphaltic concrete, cement-stabilized flexible base, cold mix, stabilized sand, limestone chip rock, and recycled asphaltic concrete in volumes ranging from 200 tons per delivery to multi-year supply agreements, typically with specifications tied to state transportation standard specifications and compliance requirements for testing, magnesium soundness values, and moisture-density relationships. Issuing bodies include city and county public works departments (City of Huntsville and Denton County, Texas; City of Austin; Santa Clara County, California; Barrow County, Georgia), state military installations (Texas Military Department), and regional transportation authorities. Award criteria consistently emphasize price, vendor proximity and delivery capability, past performance, and compliance with material specifications; contract terms typically run one to three years with optional renewals at the jurisdiction's discretion.

Recent activity clusters heavily in Texas and California. The City of Huntsville issued Bid No. 24-25 Road Materials (ITB, due June 25, 2026) for road maintenance materials with an estimated annual expenditure of $100,000 and contract term through September 30, 2031 with optional renewals; the Texas Military Department solicited Type A Grade 1-2 road base material (IFB, due June 3, 2026) for delivery to five installations statewide on an as-needed basis with estimated 2,000 tons per order and pricing subject to Producer Price Index adjustment caps; Denton County issued Invitation to Bid 26-2913 (ITB, due June 4, 2026) for Flexible Base Grade 1, Type A material with delivery commencing within five days of purchase order at a minimum of 200 tons per day; and Barrow County, Georgia solicited resurfacing services (sealed bid, due March 18, 2026) including approximately 5,230 tons of recycled asphaltic concrete patching and topping materials over 2.56 miles. California saw comparable activity: Santa Clara County issued two major IFB solicitations for pavement rehabilitation projects including flexible base and asphalt materials, with sealed bids due May 21, 2026 and April 23, 2026, requiring 142 and 45 working days to completion respectively. Wisconsin procurement activity also appears: Portage County sought flex patch leveling and sealing services (sealed bid, due March 31, 2026) across five county roads with completion by September 1, 2026.
