About this file
This is a Bid Tabulation Report for a federal construction project involving culvert replacement work in Washington State. The project, identified as WA FLAP JEFFER 134309(2) for the Two Trout Creek Culvert Replacement, was solicited under Solicitation No. 69056725B000014 and opened on April 21, 2026, by the Federal Highway Administration (FHWA) in Jefferson County, Western Federal Lands Division. Two contractors submitted bids: Conway Construction Co at $3,057,355.00 and Highline Construction LLC at $2,499,980.00, compared to the Engineer's Estimate of $2,080,000.00. The report was generated on April 22, 2026, by Haydar Mohammad and was certified by Marino Chea, the official who opened the bids. The project lead designer is Thinh Phan.
The detailed line-item breakdown comprises approximately 40 pay items covering mobilization, survey and staking, quality control, testing, erosion control measures, clearing and grubbing, excavation, riprap placement, roadway aggregate and reconditioning, and the primary work item of precast reinforced concrete box culvert installation (18-foot span, 12-foot rise) at 52 linear feet. Additional work includes guardrail systems, temporary traffic control measures, temporary stream diversion, turf establishment, plantings, and environmental design elements such as rock weirs, log barriers, root wads, fish passage boulders, bank stabilization, and streambed material installation. Unit prices vary significantly between contractors on major items; for example, the precast concrete box culvert ranges from $15,000 to $35,000 per linear foot, and temporary stream diversion ranges from $35,000 to $331,500 in lump sum pricing.
