Hydrostatic Pressure Relief System (HPRS) Assessment & Seepage Analysis

The contract entails a technical evaluation of the Hydrostatic Pressure Relief System (HPRS) at a dam facility to assess risks associated with internal erosion and piping. The scope includes detailed analysis of piezometer data to understand seepage patterns, interpretation of hydraulic gradients, and evaluation of embankment stability under varying water levels. The work is focused on identifying potential failure mechanisms related to seepage-induced degradation and determining the effectiveness of the HPRS in mitigating these hazards. Field and archival data will be used to model flow paths and pressure responses within the embankment structure. The assessment aims to provide actionable recommendations for risk mitigation and structural integrity improvements. The solicitation is open as a subcontract under NAICS code 541620 for environmental engineering services, issued by the Brazos River Authority in Texas. Interested parties must submit responses by August 14, 2026, and performance is expected to occur at the dam site, with no specific location details provided beyond the state jurisdiction. The evaluation will inform operational decisions and long-term maintenance planning for the dam’s safety and compliance with hydraulic infrastructure standards.
