guarantee Contractor's performance and has no responsibility for Contractor's failure to perform in accordance with the Contract Documents. The Indian River Farms Water Control District (IRFWCD) has requested that the previously permitted canal crossing be modified to separate ownership of the proposed carrier pipes between SWDD and NoPetro. In that process, IRFWCD also requested that the permit be modified to include additional regrading of the canal's north bank within the project extents. The process of splitting the previously issued permit brought to light the IRFWCD's request for the piped crossing to be changed from a 43" elliptical reinforced concrete pipe (ERCP) to 48" ERCP. This supplemental Work Order includes the redesign of the north bank of the project and the associated permitting coordination, as well as the minor regrading of the crossing to reflect the higher pipe. SWDD has also requested assistance with reconfiguring the drainage swale and canal outfall on the north side of the canal along the western edge of the yard waste processing area to resolve the conflict between the current swale and the NoPetro utility easement. This design and permitting is also included herein. SCOPE OF SERVICES Task 1: Leachate Tank Control Panel Prior authorization included the design, permitting, and construction associated with converting an existing centrate tank to a tank suitable for storing leachate associated with the newly completed leachate evaporation system. A mixer was installed in the tank, which has not yet been started up. A control panel for the mixer is included in the construction scope of services. Consultant will provide clarifications and respond to contractor questions associated with the construction and installation of the panel, panel components and fiber optic cable to/from the panel. This task will include coordination with the mixer manufacturer for startup and testing upon completion of the panel installation. This task will also include coordination of pulling the fiber optic cable within the previously installed conduit. The duration of this task is anticipated to be no more than 30 days of active construction, with four site visits included. Task 2: Yard Waste Driveway Improvements The prior authorization for the design, permitting and construction of the driveway improvements included services during construction; however, since the piping components were constructed independently of the driveway improvements, additional services are required to accommodate services during construction of the driveway. This task includes the stormwater, paving, grading and carrier pipe improvements associated with the driveway. This task assumes a level of effort of 4 hours per week of field time for the 80 -business day construction duration (16 weeks) estimated by the contractor, as well weekly progress meetings, shop drawing reviews, regulatory coordination, and permit closeout. Task 3: Automated Scale Improvements The County has purchased an additional inbound scale to allow for automated use by contract haulers. The project is fully designed and permitted (separate authorization). The original authorization included services during construction. Over the course of the year or so since the County purchased the scale, the Consultant partially expended the construction budget for scale Page 2 of 6
