DocuSign Envelope ID:34CC7277-FDAE-4FDE-B006-5BD22283431D ECS SOUTHEAST, LLP • Continuous observation of fill placement activities for conformance with the project geotechnical report. • Perform in-place density testing of fill materials to verify the percent compaction/in-place dry density is in compliance with the project geotechnical report. Shallow Foundations—Chapter 17,Section 1704.9 • Periodic inspections and testing by Dynamic Cone Penetrometer of soils at footing bearing level to verify that the soils encountered are satisfactory for the allowable design pressure recommended. • Periodic observations and documentation of reinforcing steel. Concrete—Chapter 17,Section 1704.2 and 4 • Collect and review concrete batch tickets to confirm compliance with the approved mix design(s). • Observe reinforcing steel prior to concrete placement to confirm bar size, grade of steel, lap splices, clearances, support methods, and cleanliness. • Anchor bolts shall be observed prior to concrete placement to confirm proper placement and embedment. • Document general curing procedures. • If extreme weather conditions are apparent, document that hot or cold weather procedures are followed • Visually check the concrete in each truck as it arrives on site for proper slump and observe general placement procedures. • Sample and test plastic concrete to include slump tests,air content, unit weight of lightweight concrete, and temperature. • Make and cure 4.0 inch by 8.0 inch concrete cylinder test specimens for compressive strength testing per specifications. (two 7-day breaks,three 28-day breaks,and one reserve) • Deliver test specimens to ECS' laboratory within 24 hours after casting. • Laboratory curing, compressive strength testing and report of concrete cylinder test specimens. • ICC reinforced concrete inspector to observe reinforcing steel. Wood Construction—Chapter 17,Section 1704.6 • Verify that the fabricator maintains detailed fabrication and quality control procedures that provide a basis for inspection control of the workmanship and fabricator's ability to conform to approved construction documents and referenced standards. • Review the procedures for completeness and adequacy relative to the code requirements for the fabricator's scope of work. • Verify any wood structural panel sheathing to ascertain whether it is the grade and thickness shown on the approved building plans. • Verify the nominal size of framing members at adjoining panel edges,the nail or staple diameter and length,the number of fastener lines and that spacing between fasteners in each line and at edge margins agrees with the approved building plans.
