P0 I <br />DEPARTMENTAL <br />INDIAN RIVER COUNTY, FLORIDA <br />MEMORANDUM <br />TO: Michael C. Zito, Interim County Administrator <br />THROUGH: Richard B. Szpyrka, P.E., P.E., Public Works Director <br />FROM: Kirstin Leiendecker, P.E., Interim Assistant Public Works Director <br />SUBJECT: Change Order No. 3 <br />66th Avenue Roadway Widening (491h Street to 69th Street), <br />Construction of 53rd Street Signalized Intersection, IRC -1505 <br />DATE: January 19, 2023 <br />DESCRIPTION AND CONDITIONS <br />On April 6, 2021 the Board of County Commissioners awarded Bid No. 2021018 to Halley <br />Engineering Contractors, Inc. (HEC) for roadway improvements for 66th Avenue from 49th <br />Street to 69th Street in the amount of $32,728,137.85. A notice to proceed was issued on June <br />1, 2021 with a contract time of 750 days to final completion. <br />Change Order No. 1 was approved on September 21, 2021 by the Board of County <br />Commissioners. Change Order 1 reduced the Contract amount by $55,000.00 to $32,673,137.85 <br />and allowed for the redesign and construction of a modified bridge design for the 66th Avenue <br />Bridge over North Relief Canal. <br />On April 12, 2022 the Board of County Commissioners approved Change Order No.2 for a <br />modified bridge design to widen 53rd Street Bridge over Lateral A Canal from 3 -lanes to 5 -lanes. <br />The Contract was modified to add 60 -days of Contract time and additional funding in the <br />amount of $841,817.35, bringing the new total contract amount to $33,514,955.20. <br />County staff asked HEC to provide a proposal to construct a signalized intersection at 66th <br />Avenue and 53rd Street, just west of the new 5 -lane bridge section that was modified in Change <br />Order 2. The added signalized intersection will improve safety to this now much larger <br />intersection containing four (4) through lanes on 66th Avenue and multiple turn lanes that will <br />accommodate future anticipated traffic volumes. <br />HEC provided a proposal to construct the signalized intersection for $814,277.14. This <br />represents an increase of $814,277.14 to the cost of the contract. The new total contract <br />amount will be $34,329,232.34. Staff has reviewed HEC's proposal, compared it with an <br />engineer's estimate and found it feasible. <br />Change Order No. 3 is proposed to compensate the Contractor for a new signalized intersection <br />containing four (4) mast arms, pedestrian signals, fiber connection, a CCTV camera and <br />C:\G ran icus\Legista r5\L5\Tem p\96e6db98-f8d0-401c-a 1c8-e415b5cf4caQ241 <br />
