Summary Explanation and Background:
The County authorized Jacobs Engineering Group, Inc. to perform engineering design services for the Sea Ray Drive Bridge Replacement. Upon completion of the design, the project was competitively bid and awarded to SEMA Construction, Inc. The length of pile needed for the replacement bridge is determined at two times, once during design and then again after the test piles are driven. During construction, it was determined that the length of piles needed for the replacement bridge would be significantly greater than what was estimated during design. Data from the test pile process, which was analyzed by a 3rd-party geotechnical and testing firm, determined that 12 of the production piles in the Sykes Creek channel should be 130’ in length; 6 of 12 production piles in the creek’s shoreline should be 90’ in length, and the remaining 6 of 12 should be 89’ long. The design team calculated production pile length at 99’ long in the channel; 62’ at the shoreline, hence the sizable difference in quantity. The difference between the design lengths and actual lengths is borne from differences in presumed and actual soil behaviors. SEMA’s proposed unit cost per linear foot is below the 6-month FDOT average pile cost. Additional costs will also be incurred by the use of a larger crane with the capability of moving the heavier pilings. This Change Order will result in an increase of $245,700 to the contract, but no additional contract time is needed.
In accordance with Board Policy BCC-27, Construction Change Orders over the thresholds established by Board Policy BBC-25, “Procurement”, which is currently at $200,000, require Board approval.
