ANALYSIS/ENGINEERING: REPLACEMENT PAGE MAY 16, 2017 AGENDA ITEM 12.G.1. PAGE 173 Masteller and Moler, Inc., (M&M) evaluated four (4) alternatives in the sewer feasibility study for the north Sebastian area. The study recommended the gravity collection alternative as the preferred method for a centralized sewer system in this area. Due to the complexity of the project along US Hwy 1, the technical specifications offered two methods of construction. The first method would be the standard open cut method and the second would be a trenchless method. A non -mandatory pre-bid meeting was held March 22, 2017, at the City of Sebastian Community Centre located on Central Avenue adjacent to the subject project area. Five (5) prospective bidders attended the pre-bid meeting and a site visit of the project area. Although there were twenty one (21) plan holders, only three (3) submitted bids. The bid tabulation of the three bidders, after corrections, are as follows: Bidder Total Price Timothy Rose Contracting, Inc. $2,977,931.58 Blue Goose Construction $3,051482.70* Non-responsive' Pipeline Utilities $3,253,545.35* *Original unit price on line item 60 was revised to comply with Bid Specitication Section 01025 Blue Goose failed to submit a signed, original revision, executed in the same manner as the original bid, to Purchasing. The lowest, responsive, responsible bid, even after the revised submittal, is approximately $1 million, or over 50% the initial estimated construction cost. The Engineer's opinion of probable cost did not include a force account of $200,000. The purpose of a force account is to cover any additional work not covered in the contract drawings per technical Speciation 01024. Therefore, subtracting this amount from the total price results in a 41.2% increase over the Engineer's opinion of probable cost. The lack of participation and higher than anticipated bids could possibly be attributed to the complexity of the project, and the abundance of construction activity available for potential bidders in the Treasure Coast area. The County's Consulting Engineer, M&M, has reviewed the bids and has recommended that the bid be awarded to the lowest responsive, responsible bidder, Timothy Rose Contracting, Inc., for a Total Bid Price in the amount of $2,977,931.58 (See Attachment 2). FINANCING/FUNDING: Staff reached out to the City of Sebastian (COS) on this project as they are a major stakeholder. The COS has voiced their willingness to support the county's efforts for a centralized sewer system. As part of their support, the City has proposed to allocate $10,000 per qualified applicant from the City's CRA funds and $5,000 per applicant from the Indian River Lagoon Council grant for a total of $15,000 per applicant. The subject project also has an existing Cost Share Program grant that is administered by the St. Johns River Water Management District (SJRWMD) that covers 33% of the initial $1.97M construction cost up to a maximum of $649,240, which will expire in September, 2018. Now that the North Sebastian Septic to Sewer Phase I project has actual unit bid prices for construction, staff has re-evaluated the funding mechanism that was approved by BCC on December 20, 2016.
