Stafford High School

This project consisted of the construction of a new three story, 288,000sf high school. This multi-phase project consisted of the construction of the new high school, a bus loop, a 162-space west parking lot, two site retaining walls, site utilities (storm sewer, sanitary sewer, water), a 555 space north parking lot, lighted tennis courts, multi-purpose fields, and tennis court retaining wall.

Froehling & Robertson, Inc. provided construction materials testing services to assist the contractor in completing the project in accordance with the project requirements, drawings, and specifications. The specific services F&R provided on this $60 million project included:

Soils – Moisture content analysis, soil classification, observation of subgrades, and use of a nuclear density gauge to perform density testing of compacted soil fill.

Cast-in-place Concrete – Monitoring the placement of concrete as well as the slump, air content, compressive strength, and temperature of the concrete.

Steel – Checking assembly for completeness and alignment, inspecting and testing all main stress carrying elements, and checking field-welded and field-bolted connections for workmanship and quality.

Welding – Verification of welder certifications and spot visual inspection of welds.

Masonry – Inspection of reinforcing steel, grout and mortar sampling, compressive strength testing, and reporting of test results.

Asphaltic Pavements – Performing roller patterns, control strips, test sections, and density testing of compacted asphalt.

Aggregate Base Coarse – Performing compaction density testing using a nuclear density gauge.
