About this file

The document is a Quality Control specification section (Section 01400) for the Thomas Mitchell Stream Restoration Project in Polk County, Iowa, intended for contractors performing work on the project. The specification outlines comprehensive quality control requirements for the project, including monitoring quality across suppliers, manufacturers, products, services, site conditions, and workmanship to ensure specified work quality. Key requirements include complying with manufacturers' instructions, adhering to specified standards, performing work by qualified personnel, and securing products with appropriate anchorage devices.

The specification details testing protocols, with specific mention of testing for cast-in-place concrete, and establishes guidelines for manufacturer field services and reports. Contractors are required to submit test reports to the Engineer, indicating test observations, results, and compliance with contract documents. The document emphasizes that testing does not relieve contractors of their responsibility to meet contract requirements, and mandates cooperation with independent testing firms. The specification serves as a technical guideline to ensure high-quality execution of the stream restoration project, which involves stabilizing and restoring approximately 3,500 linear feet of stream within Thomas Mitchell Park between July 10th and October 31st, 2025.
