Proposal for CMT & SI Services Summit Proposal # T22-0044 <br />Orange County Efland EMS Station July 14, 2022 <br />Efland, North Carolina <br /> <br /> <br />2 <br />compaction testing services during onsite grading activities. We anticipate that the following observations <br />and testing will be required during earthwork and associated construction for the following: <br /> <br />• Site work and grading; <br />• Excavations and foundations drains; <br />• Utility trench backfill; and <br />• Field density testing. <br /> <br />Compaction testing following grading will be performed in general accordance with the project’s <br />geotechnical report and project documents. We anticipate we will be required to perform field density testing <br />using American Society for <br /> <br />Task 002 – Cast-In-Place Concrete Construction and Reinforcement Placement <br /> <br />Summit will provide a Special Inspections Agent or senior engineering technician working under the <br />supervision of a registered engineer for full-time inspection, sampling, and field testing services during <br />placement of structural concrete for foundations, grade slabs, elevated posttension slabs and hardscapes. <br />Prior to the placement of concrete, we will provide a Special Inspections Agent to periodically observe the <br />size, type, and placement (lap lengths, ties, and cover) of the reinforcing steel (rebar) prior to placement of <br />structural cast-in-place concrete. We will also provide a Special Inspections Agent to observe the placement, <br />curing, and protection of cast-in-place concrete. We will perform slump, air content, unit weight, and <br />temperature testing during cast-in-place concrete placement. Concrete batch tickets will be monitored during <br />placement for mix design compliance. <br /> <br />We will mold one set of five (5) 4x8 inch concrete compression test cylinders at frequencies specified in the <br />project specifications, for each type of concrete placed per day. Concrete specimens will be picked up and <br />delivered to our laboratory after the initial on-site curing period. <br /> <br />Task 003 – Structural Masonry and Grout Placement <br /> <br />We will provide a Special Inspections Agent to observe the grout spaces, the size, type, and lap lengths of <br />the reinforcing steel prior to grout placement and perform masonry grout testing. In addition, we will <br />provide a senior engineering technician to assist with grout sampling for during grouting operations. In <br />general the testing will consist of slump and mix temperature testing and molding of one set of four (4) grout <br />samples according to the testing frequencies in the specifications for laboratory compressive strength testing. <br /> <br />Grout samples will be retrieved from the site and transported to our laboratory and placed in the proper <br />curing facilities within 48 hours. A site-curing box will be required to maintain proper curing temperatures <br />during the initial 24 to 48 hours. <br /> <br />DocuSign Envelope ID: 86DCBF93-1313-40D4-B4EA-5885A3D5CEDB
