embankment fill, structure and wall backfill, utility trench backfill, subgrade, aggregate
<br />subbase, aggregate base, materials.
<br />Field sampling and in-place density testing will be performed during asphalt pavement
<br />construction. Asphalt production plant inspection and sampling will be performed to
<br />evaluate conformance with project specifications. Laboratory testing of raw aggregate
<br />and completed mix samples will include sieve analysis, sand equivalent, percent as-
<br />phalt, film stripping, CKE, swell, and maximum density per the Construction Manual
<br />and project specifications.
<br />Field sampling and testing of concrete structures and paving during construction. Our
<br />field testing services will include sampling of concrete, and evaluating the temperature,
<br />penetration, air content, and unit weight. Concrete cylinders will be cast during con-
<br />crete placement for structures and will be transported to our laboratory for compressive
<br />strength testing. Concrete beams will be cast during concrete paving and transported to
<br />our laboratory for flexural strength testing. Concrete batch plant inspection and sam-
<br />pling will be performed to obtain raw aggregate samples for acceptance testing and to
<br />evaluate the batch plant operation for conformance with project specifications. Labora-
<br />tory testing of aggregate samples will include sieve analysis, sand equivalent, and
<br />cleanness value per the Construction Manual, Standard Specifications, and project
<br />Special Provisions. Further, specialized tests, such as L.A. rattler, durability index, spe-
<br />cific gravity, etc., will be performed upon request by the Resident Engineer.
<br />Field inspection of the construction materials, both during fabrication/ erec-
<br />tion/construction and after construction completion (finish project inspections)
<br />performed by inspectors registered with the County of Orange and other agencies
<br />(ICC, AWS-CWI). Inspections may include:
<br />• Reinforced concrete, including foundations, cast -in-place concrete structures, and
<br />miscellaneous concrete construction.
<br />• Structural masonry, including retaining walls, sound walls, building and site walls
<br />• Onsite and fabrication shop welding and bolting of structural steel.
<br />• Non -Destructive Testing (ultrasonic, magnetic particle and dye penetrant)
<br />• Roofing, painting and coating
<br />• Laboratory testing on collected construction material samples in accordance with the appro-
<br />priate California Test, AASHTO, and ASTM test methods and utilizing our Caltrans and
<br />AASTHO certified laboratories. Laboratory testing may include maximum dry density and
<br />optimum moisture content of the soils to be placed as fill or backfill; compressive strength
<br />testing of the concrete, and conformance testing (including sieve analyses, sand equivalent,
<br />R -value, cleanness value and durability tests) on the proposed aggregate subbase, aggre-
<br />gate base, asphalt concrete, and concrete pavement. Testing will be performed at
<br />frequencies required by the Caltrans Construction Manual and/or applicable project specifi-
<br />cations.
<br />• Preparation of daily reports and other memoranda to summarize the field operations and
<br />test results. Our reports will include the information required by the review agencies.
<br />• Preparation of a final report summarizing the results of our field and laboratory test results,
<br />including final report on grading and certification of compliance.
