Structural Dynamics reviewed Powder River Construction's (PRC) bid and had a phone conversation with their project manager and determined that a subcontractor bid for the HVAC equipment and work was left out of their bid. Despite this discrepancy, PRC intends to complete all the work in the contract for their bid amount. Structural Dynamics' bid recommendation letter is attached. |
