Del Valle High School Drainage and Pavement Rehabilitation
The Del Valle High School Campus is situated in eastern El Paso, Texas.
The project encompassed drainage and pavement rehabilitation in the area in front of the campus, which included the construction of sidewalks, curbing, ramps, flumes, driveways, athletic enhancements, drainage improvements, utility line extensions, concrete, and asphaltic paving. Earthwork requirements also entailed on-site soil improvements in various areas within the project site.
CQC provided engineering evaluation services, including soil sampling and evaluation during the design stage. This provided an accurate assessment of the condition of the subsurface soils and offered clarity regarding expectations. CQC also collaborated with the design team in reviewing structural plans, details, and specifications for the concrete roadway improvements.
Project Manager Rojas and CQC engineers closely collaborated with the design team to prepare the testing scope of work and the CMT (Construction Materials Testing) proposal based on findings collected during the project's initial stages. Testing and monitoring services included performing soil moisture-density relationships for both on-site and imported soils used during construction, verifying soil compaction testing on existing subgrade soils, base course, and cement-stabilized soil materials. Results were consistently provided under the direct supervision of CQC’s Project Engineer, facilitating the Contractor's uninterrupted fieldwork and avoiding disruptions to the overall schedule. Additionally, CQC conducted testing on the asphaltic-concrete pavement placed at the project site, which included density tests, thermal profile tests, and pavement observation reports. All laboratory tests were conducted in accordance with City and TXDOT test procedures.
CQC supported the design team in developing subsurface soil improvements. Soil-Portland cement mixtures were implemented in sections where high plasticity clay soils were encountered during the geotechnical engineering evaluation phase. Recommendations and guidelines were promptly communicated to the project civil designer and General Contractor to properly address the stabilized subgrade soils.
