Cost of Construction

The table below summarizes the results of the Engineer’s Opinion of Probable Cost (EOPC). The full EOPC is available in Appendix S of the final design report. Costs are estimated using previous ADOT bid tabulations and by referencing local projects of similar scope. Costs include material and labor for the demolition, roadway construction, and hydraulic structure construction scopes of work. Contract prices are also included. Two alternative costs are provided for each alternative structural section as outlined in Section 4.2 of the final design report. Major cost items include the aggregate base course and paving scopes of work. The cost for alternative 1 is approximately 6.7 million dollars. The cost for alternative 2 is approximately 6.5 million dollars.
