Copper Canyon, TX

Engineering construction documents were prepared for the layout and construction of an 80 foot span bridge for vehicular traffic. The hydrological/hydraulic aspects of the project included preparing a FEMA Letter of Map Revision (LOMR) associated with the overall design factors of the new bridge. The hydrological modeling employed the use of HEC-RAS software to reflect existing and proposed conditions of the creek's hydraulic profile (Poindexter Branch). The complete scope of engineering services also included geotechnical investigations for roadway designs. The structural engineering portion of our scope included the design of bridge abutments, pier support systems and truss system design.

The overall project design requirements also included the stabilization of the creek embankment. The soil embankment stabilization technique employed the use of "reinforced earth" technology, which utilized geotextile fabrics. Geotextile fabrics were utilized to offer side slope erosion protection. Geogrid material was made a part of the "gabion" retaining wall's anchoring system, which further added to the embankment's stabilization.
