C-44 Reservoir/STA Project, Contract 2

H2R provided construction materials testing, materials inspection, and geotechnical services for this new above-ground reservoir and STA project. This project is the primary component of the Indian River Lagoon-South project, which in turn is a key element of the Comprehensive Everglades Restoration Program. The Indian River Lagoon is considered the most biologically diverse estuarine system in the continental United States and is home to more than 3,000 species of plants and animals. The C-44 Reservoir and Stormwater Treatment Area is the first component of the multi-billion dollar Indian River Lagoon-South project. The project is designed to capture 65 percent of the average annual stormwater runoff in the C44 basin. The reservoir component will hold up to 50,600 acre-feet, or 16 billion gallons, of water at an average depth of 15 feet.

H2R served as the quality control representative and geotechnical engineer for the project and performing support services for various dam construction elements. Field services included materials testing and sampling, exploratory drilling, and Cone Penetrating Testing which was correlated to density in lieu of conventional field density tests. In addition, H2R provided multiple quality control inspection staff as well as professional services for engineering including shoring and dynamic pile testing, Contractor Submittals, and project data management services.

H2R developed software to manage the immense volume of data generated for this project. In addition, H2R was able to gain Government Acceptance of CPT testing in lieu of nuclear density testing for the toe trench drain, developing a testing program, developing correlations and a computer program to seamlessly integrate the collection and reporting into the overall quality control program.
