APTIM will perform site visits on days of active construction, which are assumed to be 5 days per week, and will provide up to eight (8) hours of observation per visit. It is assumed that one (1) site visit per week will be scheduled on the same day as the weekly progress meeting described in Task 1. APTIM will coordinate with the Contractor to perform site visits on days when on-site construction activities are scheduled. The activities, observations, photographs, discussions with the Contractor, and other issues will be documented in a daily observation report and submitted to the County. APTIM's on-site representative will: • Observe all aspects of construction activities at the beach including periodic beginning of the day and end of day beach fill operations and periodically visit the project sand source • Visually assess the quality of fill material delivered to the project site and placed on the beach • Observe the Contractor's work for compliance with the contract documents and permits • Photograph and document the project as the work progresses • Communicate issues, deviations, and/or consistencies that may arise • Attend progress meetings The proposed budget for this task includes up to 108 days of construction observations, based on the tentative schedule. Upon completion of sections of constructed beach, two (2) duplicate sand samples will be collected at each FDEP Reference Monument profile line to assess the grain size, silt content, gravel content, and Munsell color for compliance, in compliance with the approved Sediment QA/QC Plan. One (1) sample will be quantitatively tested and the other archived for 120 days after project completion. Deliverable APTIM will prepare observation reports summarizing each site visit, which will be used to document the project progress and events and will be provided the following day after construction activities. APTIM will prepare a summary table of the sediment samples and test results for the sediment compliance parameters, and a complete set of laboratory testing results as required by the approved Sediment QA/QC Plan. The sediment testing results will be included in the Project Completion Report. Schedule A fixed timeline cannot be provided because it is dependent upon the Contractor's progress and construction schedule. Cost The lump sum cost for this task is $225,162.60.
