17-Attachment CC - Preliminary Engineering Report.pdf

This Preliminary Engineering Report is a technical document prepared for the Harris County Flood Control District in Texas to support professional architectural and engineering services for the South Mayde Creek Bypass Channel and Stormwater Detention Basin project. The report provides detailed engineering analysis and recommendations for the proposed improvements to manage stormwater in the project area. The document establishes the technical foundation for the scope of work that qualified architectural and engineering firms will be expected to undertake, including design development, permitting support, and construction administration services. The preliminary findings and recommendations outlined in this report will inform the basis for proposals submitted in response to the request for qualifications.

The report contains essential project data including site conditions, hydrological analysis, preliminary design parameters, and estimated project costs that firms should review prior to submitting qualifications. As a preliminary engineering document, it identifies the key technical challenges, environmental considerations, and regulatory requirements that will govern the design and construction phases. The information contained herein establishes the current baseline conditions and anticipated project scope that responding firms will use to develop their qualifications, proposed methodologies, and fee structures for the professional services required to advance this flood control improvement project.
