(TCCM). Staff forwarded these proposals to Geosyntec for review and recommendation on the lowest most qualified contractor to perform this work on the landfill property. ANALYSIS: Geosyntec has provided a bid evaluation report considering Comanco, Golder and TCCM for this project. The total bids (without any contingency) are: (i) $289,975.00 for Comanco; (ii) $142,200.00 for TCCM; and (iii) $151,435.26 for Golder. The Engineering Construction Estimate (ECE) for the Ditch Work is $149,975.00. According to Geosyntec, the unit costs from Golder were comparable with those within the ECE, TCCM did not provide unit costs, and the unit costs from Comanco were significantly higher than the ECE for various items. The lowest bid is from TCCM in the amount of$142,200.00 followed by Golder in the amount of$151,435.26. Geosyntec further reviewed the two lowest bidders in terms of qualification and experience. TCCM did not provide any qualification and relevant experience on earthwork and landfill-related construction. Based on Geosyntec's limited internet search, they could not find that TCCM had any project experience related to landfills. On the other hand, both SWDD and Geosyntec have worked with Golder as they are the current landfill gas operations and maintenance subcontractor to Republic. In addition, Golder provided landfill construction related services in their proposal and has direct construction experience working on the Indian River County landfill site as they recently completed the flare relocation project on schedule and under budget in 2012. Overall, prior experience working on an active landfill site is key to maintaining the safety of employees, residents, equipment and facilities. Geosyntec recommends SWDD utilize Golder through Republic as the general contractor for the ditch enhancement project. Geosyntec further recommends a 20% contingency on the project. Also, Republic has requested a 10% administration fee which is allowable within their contract subject to SWDD Board approval. The total cost of the project utilizing Golder as a subcontractor under Republic is approximately $199,894.54 which includes a 10% administration fee and a 20% contingency fee. This total is less than the available contingency fee of$364,734.58. Staff recommends approval of an amendment to Republic's landfill contract to utilize Golder as a subcontractor that based on their qualifications&their reasonable price proposal. ACCOUNT INFORMATION: Funding for the Ditch Enhancement work as a sub-element of the Segment 3 Cell 1 Phase 2 lateral expansion project is budgeted and available in the SWDD landfill account WIP number which is funded from SWDD assessments and user fees.
