This is a drawings file for the Iowa Department of Administrative Services related to the West Parking Lot #2 replacement project at the Hoover Building located at 109 SE 13th Street, Des Moines, Iowa 50319. The drawings document the scope and specifications for the parking lot replacement project, providing detailed visual representations and technical specifications necessary for contractors to understand the project requirements and submit competitive bids.

The drawings serve as essential contract documents for contractors to reference during the bidding process, ensuring accurate cost estimation and project planning. These technical drawings, in conjunction with other bid documents such as the scope of work and project description, establish the baseline requirements for the parking lot reconstruction and allow prospective bidders to evaluate the full extent of work required to complete the project successfully.
