Mr. Himanshu Mehta, P. E. 15 November 2022 Page 6 site on a weekly basis (or as requested by the contractor) to collect soil samples from the off-site borrow source soil stockpile for laboratory conformance testing (see below), monitor construction progress, and conduct in-situ nuclear density and moisture content testing to evaluate the adequacy of compaction of the subgrade. Soil samples from the off-site borrow source will be tested by an independent geotechnical CQA laboratory for conformance with the Technical Specifications and CQA Plan. The CQA Technician will be responsible for CQA activities throughout the Project including monitoring construction, coordinating soils testing (if needed), and maintaining documentation of CQA activities at the site. Any non -conforming or questionable practices observed by Geosyntec will be brought to the attention of the concerned parties for review and correction. Task 4.2: CQA Surveying Geosyntec will subcontract the services of a Registered Land Surveyor to provide the surveying required and prepare the as -built record drawing of the Cell 3 subgrade construction. Geosyntec has selected Peavey & Associates (Peavey) of Fort Meade, Florida to provide surveying services. Peavey will assist SWDD staff in the subgrade preparation work and provide data to check material quantities for measurement and payment purpose. A copy of Peavey's proposal is enclosed as Attachment A. Task 4.3: CM and Engineering Support Services Geosyntec will provide CM and engineering support services throughout the duration of the site preparation work. Construction management activities will include conducting pre -construction and monthly construction progress meetings with the entity selected by the SWDD to prepare the site for the construction. Geosyntec will evaluate Contractor payment requests, verify quantities and conformance with the plans and specifications, and provide contract administration. As part of this phase, Geosyntec will review laboratory conformance and field performance tests results (performed through the Contractor) and as -built record drawings for inclusion in the Cell 3 construction certification report. Geosyntec will therefore review all test results and drawings to ensure compliance with the project specifications and FDEP-issued permit for the Class I Landfill. Phase 5: Abandonment of Existing Monitoring Wells Construction of Cell 3 will require abandonment of two groundwater monitoring well clusters (MW41 and MW -42). In addition, LFG migration monitoring probe GW -00011 that is located close to the flare station would have to be abandoned and replaced with a new probe in order to NCP2022/XL222460/1L2072 Segment { Cell 3 lite Prepurution doe
