About this file
This is an Earthwork Summary report prepared by the City of Kingman, Arizona for the Stage IV submittal of the Kingman Crossing Boulevard Traffic Interchange project (H7147). The document presents detailed excavation and embankment quantities organized across five project phases. Total excavation quantities amount to 378,466 cubic yards, with roadway excavation comprising 313,225 cubic yards, drainage excavation at 41,591 cubic yards, pipe excavation at 9,814 cubic yards, structural excavation (bridges, walls, and box culverts) at 10,712 cubic yards, and riprap excavation at 3,124 cubic yards. Corresponding total embankment quantities are 72,493 cubic yards, plus an additional 8,699 cubic yards accounting for a 12 percent shrink factor, resulting in total embankment with shrink of 81,192 cubic yards. The project includes waste quantities of 297,274 cubic yards distributed across phases. Work is segmented into five phases, with Phase 1 and Phase 3 representing smaller scale activities, while Phases 2 and 4 contain the largest quantities associated with the northbound and southbound I-40 interchange improvements, respectively. Phase 5 contains no quantities. The report includes detailed breakdowns for pipe culvert installation (50 pipe references totaling 9,814 cubic yards excavation and 2,204 cubic yards backfill), box culvert work (9 structures with 340 cubic yards structural excavation and 449 cubic yards backfill), bridge structures (two overpass structures with 3,190 cubic yards structural excavation and 1,920 cubic yards backfill), and wall structures with 7,182 cubic yards structural excavation and 2,402 cubic yards backfill.
The project encompasses major infrastructure improvements including the construction of a traffic interchange at Interstate Highway 40 and Kingman Crossing Boulevard, completion of Kingman Crossing Boulevard design and construction, and development of approximately 128 adjacent city-owned acres. Ground compaction work totals 2,312 cubic yards across all phases. The City of Kingman issued a Request for Qualifications (2026-RFQ-019) seeking qualified master developers with documented experience on similar large-scale infrastructure projects. Responses were due by 5:00 pm Arizona time on Thursday, November 19, 2026, with questions to be submitted by 5:00 pm Arizona time on Friday, November 6, 2026 through the OpenGov procurement portal at https://procurement.opengov.com/portal/cityofkingman. The project involves retail, commercial, and complementary uses on city-owned property south of I-40 at the Kingman Crossing Boulevard intersection. Responses must be submitted through the OpenGov procurement portal, and the City reserves the right to reject any non-compliant response or any response when cancellation serves the city's interests.
