Place embankment for trail and construct base for trail on the east side of John Young Parkway. 3. SCHEDULE As of November 30, 2014, the project is ahead of schedule by 9.6 % when comparing dollars vs. time. The revised CPM Schedule indicates the project is slightly ahead schedule. The main span bridge concrete deck placement and pre-cast concrete panels on structural towers are schedule for December and January, See Exhibit A for Schedule and Complete Revenue cost analysis. 4. Issues The Pre-Cast concrete panels production was delayed due to the samples being rejected for Tri-color hand applied stained brick portion. The manufacture did not submit samples with a tri-color hand applied stained brick; therefore, the samples were rejected twice and set back the production. DOT has determined this project the Davis Bacon wages should have been part of this contract and the project is currently out of compliance. It was 4 of 20

5 determined at the beginning of the project that the prevailing wages would not be required on this project. However, DOT is currently discussing this issue with FHWA to determine how to get the project in compliance. 5.

7 6. Change Orders Executed Change Orders: Change Order #1 consist of Foundation 22(A) and 14 (A) overlapping each other and could not be constructed as a single foundation. VHB reviewed the foundation and determined the two foundations needed to be independent of each other. Foundation 22(A) had to be lowered 5.5 feet. The resulting changes did not incur additional compensation. Change Order #2 consist of the following: On plan sheet B1-02, General Notes, Note D-1 states "Contractor is permitted to substitute class II concrete (f'c=3,400 PSI) for CIP substructure construction at no additional cost to the owner. Contractor's Engineer shall verify that proposed substructure dimensions and reinforcing are not adversely affected by the concrete substitution." With the permission of the City, Gibbs and Register retained VHB to provide analysis supporting the class II concrete (f'c=3,400 PSI) for class IV (f'c=5, 5000 PSI) for all CIP substructure elements. VHB concluded that the substitution will be acceptable with the following revisions to the contract plans: Foundation (B1-23 & B1-24) Reinforcing shall be revised from 6 (top and bottom), to 6 (top) and 6 (bottom) Columns (B1-23) Clear cover shall be revised from 2 ½ to 4 Pier Cap (B1-23 & B1-24) Reinforcing shall be revised from Equal Spacing (E.F.) to Equal Spacing (E.F.) Concrete Cover -shall be increased to 4 at all column locations. Change Order #3 consist of the following: Item #1- The purpose of this change order is to remove the language for reimbursing the City for overtime incurred by the City Inspectors from the project manual. The City is under contract with Infrastructure Engineers, Inc. for the inspection services. Item #2- The contract plans specified Fabric Formed Concrete Rip-Rap located around the footers, wingwalls, and side slopes of the box culvert on the upstream and downstream side. However, the Technical Special Provision for the material requirements, installation, and required test procedure for the product was omitted from the TSP. The TSP needed to be added to the Contract in order for FDOT to approve the Fabric Formed Concert Rip-Rap Submittal #13. 7 of 20

8 Change Order #4 consist of the following: Item #1 (revision 3) - On contract plan sheet 32, the toe and heel dimensions of the Box Culvert Wingwalls were reversed. This error was noted by the contractor and reviewed by the EOR. The EOR agreed and submitted revision #3 to correct the error. While revising the wing wall dimensions, other discrepancies of the box culvert contract plans were found with the dimensions and quantities. The concrete quantity decreased slightly and the steel quantity increased. The new concrete quantity is CY, CY less than the final plan quantity and the new steel quantity is 181,764 LBS, 26,198 LBS( TN) more than final plan quantity. Revised Plan sheets 01, 03, 07, 08-09, and Due to the revised quantities, Gibbs and Register, Inc. requested additional compensation for the adjusted quantities. Note G&R is entitled to $22, due to this revision. (-13.63CY x $206.29) + (13.099TN x $ ) = $22, Item #2 (revision 4) - The plan elevations for the Top of the Caps did not correlate to the Finish Grade Elevations of the Eastern and Western Ramps. The EOR reviewed the elevations and concluded the elevations at the Main Pier Caps needed minor adjustments in order to achieve the proper clearance with the main span of the pre-fab bridge with the existing grade of JYP. Revised Plan sheets B1-24, B1-25, B1-27, and B1-47. This revision did not warrant additional compensation. Item #3 (revision 6) - Due to revision 3 request for additional compensation by the contractor, the EOR reviewed revision 3 in order to eliminate the additional cost. Plan sheets 01, 03-09, and 32 was revised to eliminate the additional cost. The EOR removed the skew of the box culvert and proposed the end treatment of the box culvert be perpendicular with the canal and the Box Culvert was shorten by 5 LF. The new concrete quantity is CY, CY less than the final plan quantity, the new steel quantity is 166,837 LBS, 11,271 LBS (5.64TN) more than final plan quantity, and the new length is 175 LF. After all negotiations with the contractor regarding revision 3 and revision 6, all parties agreed to a zero dollar change order. This revision did not warrant additional compensation. Item #4- Additional Weather Days- 14 additional days added to the contract due to inclement weather. Weather days are March 17, 18, 19, & 20, April 16 & 30, May 15, June 11, 12, 13, & 30, July 17, 23, August 8. The new contract days is established at of 20

9 No additional compensation is allowed for inclement weather. Change Order #5 consist of the following: Construct Tower Panel Footers at Footer # 12 and 13 for the metal framing to support thin set tile work around the columns EXCAVATION FOR TOWER PANEL FOOTER. In response to RFI 031- The final grade elevations shown on plan sheets A1-02 & A1-03 was not correct. The architectural units shown on plan sheet A1-01 & A1-03 did not correlate to the engineering units shown in the structural drawings. These plan sheets were revised in response to RFI 27 but the finish grades provided did not match the existing grades in the field. RFI 31 was generated due to the discrepancy between the revised plan sheets and existing field conditions. Please see attached plan sheets A1-02 & A1-03 for corrected elevations in red and concrete support detail for thinset tile and metal framing. In order to meet the design intent of the thinset tile and metal framing, a concrete support footer needed to be designed to support the metal framing. The details on plan sheet A1-02 & A1-03 show the thinset tile and metal framing resting on top of footer #12 and 13 and the thinset tile exposed to elevation and However, the finish grades varies on each column from to Therefore, the thinset tile and metal framing could not rest on top of footer #12 and #13 as shown on plan sheet A1-02 & A1-03. In order to provide the support needed for the thinset tile and metal framing, a concrete footing needed to be constructed two feet below finish grades. Due to the delay of the metal framing, 12 days were added to the contract. Upcoming Change Orders: Change Order #6- Second part of the Tower Panel Footers at Footer # 12 and 13 for the metal framing to support thin set tile work around the columns EXCAVATION FOR TOWER PANEL FOOTER. Change Order #7 consist of Revision 7-added signage and video board. Change Order #8 consist of revised arch anchor reinforcing steel. Change order will be based on time and materials. Change Order #9 consist of added rubble rip-rap underneath abutment #1. 9 of 20
