The compaction of soils for 12" Water Line, South of Buildings 1 and 2 from STA 1+00 to 3+00. Please see the attached sketch. Utilizing the nuclear test method to check the compaction of soils; test results indicated that the compacted material, at the areas and elevations tested, met or exceeded the project requirements of 95% of the maximum dry density with a moisture content above optimum, as obtained in our laboratory using the Standard Proctor Method (ASTM D-698). Locations and elevations of all tests are based on stakeout provided by others. We cannot be responsible for structures located off of the observed engineered pad, misaligned utilities or stakeout errors causing uncontrolled fill to be placed in structural areas. 2. The placement of 4000 psi concrete for Lot 2R Storm Drain Line 6 Y-Inlets at STA 2+67, STA 1+78, STA 0+67, Storm Drain Line 3 Grate Inlet, and Storm Drain Line 2 Curb Inlet. Please see the attached sketches. The required test limits were determined to be a slump of 3-5 inches, air content of 3-6 %, batch to placement time of 90 minutes, and concrete temperature range of 55-90 degrees Fahrenheit. Concrete observed on this date appeared to be placed in compliance with project specifications with regard to temperature, slump, and air content. THE BATCH TO FINAL PLACEMENT TIME EXCEEDED THE 90 MINUTE DESIGN PARAMETERS. 77°/ Cloudy 45.00 2.25 0.25 0.00 12:45P 03:00P WL BF and Inlet Conc Location On-Site Time Lab Time Client Grapevine, TX Arrival Departure Summary of Services Performed (field test data, locations, elevations & depths are estimates) & Individuals Contacted.
