DocuSign Envelope ID:34CC7277-FDAE-4FDE-B006-5BD22283431D ECS SOUTHEAST, LLP • Observe and document the control joints are installed per the approved plans for spacing and installation. • Observe and document the specified control joint filler material is being installed as specified. • Obtain samples of masonry mortar for mortar/aggregate ration testing in accordance with ASTM C-480 and C-270 note as specified. • Fabricate mortar cubes and grout prisms for compressive strength testing. • Obtain samples of CMU materials for compressive strength testing. • Observe the fabrication of structural masonry prisms. Aggregate Base Course • Observe proofrolling of soil subgrades to receive stone and paving. • Observe proofrolling of ABC stone elevations. • Analyze the Aggregate Base Course stone for optimum moisture content and maximum dry density utilizing the specified Proctor method and conduct thickness measurements. • Conduct in-place density tests on aggregate base course to verify compaction. Asphalt Quality Control • Review Job Mix Formula data for proposed bituminous pavement materials. • Monitor temperature and density of asphalt pavements during installation and provide information as to the performance of these materials during installation for the purpose of quality control. Understanding Construction Materials Testing Construction Materials Testing (CMT) are performed to help provide the project's contractors, designers, owners and local code officials some indication of the level of compliance obtained by the installing contractors with the project specification. These services are provided at periodic intervals which typically are defined by the project specifications and on some occasions by the applicable building code. Test locations for most materials, i.e. soils, concrete and fireproofing, are generally based upon random selection; as such not all materials incorporated into a construction project are tested or observed. Obviously the greater the testing frequency, the greater the confidence level that the test results are representative of other untested areas, however, no amount of testing can assure 100% compliance. Testing and observation services provided by ECS do not relieve the installing contractors from their obligation to install all materials in accordance with the applicable project plans and specifications. ECS makes reasonable effort to test in accordance with the applicable project requirements and to identify areas of materials that may not comply with the project specifications. However, due to the periodic and random nature of our testing, we cannot guarantee that all materials have been installed in accordance with the specifications. The responsibility to correct or remediate non-complying conditions, even non-complying conditions discovered after testing or during subsequent phases of construction remains solely with the installing contractors.
