EXPLANATION:
On May 6, 2011, the attached Request to Advertise was approved and filed with the Clerk of the Board. The project was advertised on June 21, 2011, and on August 10, 2011 five engineering contractor firms proffered bids for the subject project. The lowest bidder, M & J Construction Company of Pinellas County, Inc., proffered a base bid of $4,274,066.81, sixty-five percent over the County's cost estimate. The second lowest bidder, Kiewit Infrastructure South Co., proffered a base bid of $4,638,674.70, nine percent over the lowest bidder. The third lowest bidder, Coastal Marine Construction, Inc., proffered a base bid of $4,828,196.76, four percent over the second lowest bidder.
Given that the low bidder�s price exceeded the County�s cost estimate by more than fifteen percent, PWWMD recommends rejection of all bids received. The difference can be attributed in part to inherent difficulties in estimating this type of work due to its uniqueness. There was also an apparent reversal in the downward trend of construction prices evidenced when comparing selected items for this project with the prices in other recent similar projects. PWWMD will also explore modifying the Scope of Work and the use of Value Engineering to reduce the project cost.

Background

The Miami Avenue Bridge provides a vital link to the Downtown Miami area. As a result of the FDOT inspections, the PWWMD performed a Load Rating Analysis of the bridge and concluded that due to the condition of the existing deck, it was necessary to place signs on the bridge limiting the weight of the vehicles that can safely cross it until the bridge is rehabilitated. The Twin Bridges, (No�s 874663 and 874664) were built in 1985 and have major deficiencies identified in the Florida Department of Transportation (FDOT) Report, including the following:
a. Deck corrosion is advanced and section loss and/or connectivity is sufficient to warrant analysis to ascertain the impact on ultimate strength and/or serviceability of either element of the bridge.
b. Main steel girders require painting. Because surface corrosion is prevalent, there may be exposed metal but there is no active corrosion which is causing loss of section.
c. Locks are operating poorly, therefore, replacement is required.
d. Trunnion: Major misalignment, wear or corrosion is extensive and operation of the drive system may be affected.
