Contract value

$500,000

The solicitation does not disclose the engineering services fee. However, the construction portion of the bridge is estimated at $5 million (see the “Construction Cost Estimate” in the specifications). Engineering design contracts for a bridge of this scope typically range from 5 % to 10 % of construction cost, depending on the depth of design and study requirements. Assuming a mid‑range 7 % fee, the engineering services would be roughly $350,000. Adding possible overhead for project management, travel, and contingency could bring the total to about $400,000‑$500,000. Therefore, a reasonable ball‑park for the overall contract value (engineering services only) is approximately $500,000, while the overall project (including construction) is $5,000,000.
