This is a project announcement by the Brazos River Authority regarding a Request for Proposals (RFP) for preliminary engineering services related to the Lake Limestone Hydrostatic Relief System Assessment at Sterling C Robertson Dam. The project encompasses site reconnaissance, data review, condition assessment of the Hydrostatic Pressure Relief Systems (HPRS), seepage and stability analysis, visual inspection of drainage infrastructure, bathymetric surveys of the downstream river channel, and other services as outlined in the RFP. The Sterling C Robertson Dam, constructed in 1978, features a 400-foot concrete spillway, 3,000-foot east and west embankments, and operates at a normal pool elevation of 363 feet mean sea level with a storage capacity of 208,017 acre-feet. The RFP is estimated to be advertised in August 2026, with all questions during the advertising period to be submitted through the BidNet Direct portal or directed to Allison Sheeler, Purchasing Agent, at allison.sheeler@brazos.org. Interested parties may also contact Steve Hamlin at 254-761-3172 for project inquiries.

The estimated total project budget is $11.2 million, comprising $5.2 million for construction, $3.5 million for design, and $2.5 million for preliminary engineering. The preliminary engineering scope represents the current focus of this solicitation. The estimated scope and budget are subject to change pending review of the published RFP. The HPRS instrumentation currently consists of well point type piezometers, settlement plates, and survey monuments that require assessment and potential repair, replacement, or abandonment based on their condition evaluation.
