Home My WebLink About2010 10 25 Consent 202 Agreement With Wal-Rose For O'Day Drive Pond Improvements COMMISSION AGENDA CONSENT X INFORMATIONAL ITEM 202 PUBLIC HEARING REGULAR October 25, 2010 MGR /DEPT / Meeting Authorization REQUEST: Public Works Department requesting authorization to enter into a contractual agreement with Wal -Rose, Inc. for construction of the O'Day Drive Pond Improvements (ITB #008- 10 -BF) SYNOPSIS: The O'Day Drive Pond Improvement project consists of the removal and replacement of outfall structures at the O'Day Drive wet detention pond in Oak Forest. Staff recommends awarding the construction contract to the low bidder, Wal -Rose, Inc., in the amount of $47,770.50 plus a 10% contingency. CONSIDERATIONS: • The O'Day Drive wet detention pond is located in Oak Forest Unit 8 between 1132 and 1142 O'Day Drive. The existing concrete overflow spillway and three adjacent circular outfall structures have failed. The three circular outfall structures are known as "vertical volume recovery" structures (or "VVRs ") that use sand media filters to treat stormwater. The VVR structures are difficult to maintain and they do not meet current stormwater design standards. The City's stormwater system has approximately six ponds that currently utilize VVRs, and these are all scheduled to be replaced over the next several years. The O'Day Drive pond is the first VVR replacement project. • The O'Day Drive Pond Improvement project consists of the removal of the failing structures and replacement with a new control structure meeting current stormwater design standards. A baffle wall will also be installed in the pond to improve circulation. The project will restore the stormwater treatment and flood control function of the pond and it will improve the appearance of the area. • The project was advertised for bidding in the Orlando Sentinel on Sunday, August 29, 2010. Bids were received and opened on September 23, 2010 with the results as follows: October 25, 2010 Agenda Item #202 Page 2 of 2 Invitation to Bid #008 -10 -BF - Bid Results Bidder Bid Price 1 Wal -Rose, Inc. $47,770.50 2 Cronin Construction Corp. $51,353.00 3 Atlantic Civil Constructors Corp. $62,242.00 4 CFE, Corp. $65,035.00 5 Estep Construction, Inc. $98,014.00 6 CBC Group, LLC $107,977.00 • Staff has reviewed the bids and recommends that the bid be awarded to the low bidder, Wal -Rose, Inc. in the amount of $47,770.50 plus a 10% contingency. • Construction is expected to begin by November 1, 2010 and is scheduled to be complete by February 1, 2011.
