THIRD AMENDMENT TO AGREEMENT CARSON REDEVELOPMENT AGENCY PARSONS Project No. 919: Wilmington Avenue Interchange Modification at the 1-405 Freeway. 4 Caltrans has offered ars option to eliminate the proposed work along the I-405 southbound off - ramp in lieu of widening the outside lane and shoulder widths on the freeway mainline at the ramp entrance to full standard in addition to constructing the ramp improvements. The widening on the mainline would have increased the cost to the project by approximately $2 million while the elimination of the ramp improvements would result in cost savings of $1 million to the City's project. The work on the ramp is required under the Project Study Report (PSR) and the Draft Project Report (DPR) but Caltrans has offered the City the option to eliminate this work frons the City's project and Caltrans would complete this work in the fixture under a separate contract. Tasks 1, 2, and 3 below show the additional engineering services required to incorporate these changes into the Project Approval/Environmental Document (PA/ED) and the Plans, Specifications, and Estimate (PS&E). Furthermore it was determined by Shell Oil Company that modifications to their utility bridge beneath the existing Dominguez Channel Bridge were also required for the project. This utility bridge is wholly owned by the Shell Oil Company and it carries a number of oil pipe lines over Dominguez Channel. The utility bridge is a completely separate structure and the required modifications to facilitate widening of the Dominguez Channel Bridge became necessary after a complete survey of the existing bridges was performed. Task 4 below shows the additional design services that were required for the modification of the utility bridge. Task I — Revise Project Report ($ 16,693.96) Consultant will update the Project Report to reflect the elimination of improvements to the southbound off -ramp. Consultant will update the project description, update the accident analysis using current data, update the design exceptions description, revise layouts and exhibits, update the transportation management plan, update the storm water data report., and revalidate the CEQA and NEPA documentation accordingly. Task 2 — Revise Design Exception — Fact Sheets ($5,407.16) Consultant will update the advisory and mandatory design exceptions fact sheets to reflect the elimination of improvements to the southbound off -ramp and will maintain coordination with Caltrans towards the approval of the fact sheets. Task 3 — Revise Plans, Specifications and Estimate ($ 42,96171) Consultant will update the project plans to reflect the elimination of improvements to the southbound off -ramp. The following sheets will be revised.

Consultant will update the quantity calculations and the engineers cost estimates accordingly. Consultant will revise the project specifications to reflect the changes described above. Task 4 — Modification of Utility Bridge ($ 59,089. 10) Consultant scope of services includes site visits, meetings with Shell Company representatives and hand measurements of the existing utility bridge. There are no as -built plans for the existing utility bridge therefore, field surveys are necessary. Shell Oil Company has confin- zed the project scope, method of construction, and Shell Oil Company requirements. Shell Oil Company requirements need to be reflected both in the project specifications and the plans. Consultant scope requires the preparation of utility bridge modification plans. The utility bridge design modification process consists of developing constructions plans, modifying Dominguez Channel Bridge Plans, preparing back up calculations, editing special provisions, preparing quantity tape off and marginal estimates, and submittal to Caltrans for review and approval. b addition, Dominguez Channel Bridge Foundation Report requires updates for existing and new pile issues and submittals to Caltrans for review and approval. A total of 4 drawings are required for the proposed modifications. A redesign of the Bent 6 of the Dominguez Channel Bridge is necessary to avoid interference with the existing Beat 3 of the utility bridge. Three Dominguez Bridge Channel drawings need to be revised for this purpose. Task 5 — Potholing all existing Utility limes Since there are numerous sensitive pipelines within Wilmington Avenue right-of-way, Caltrans requested a precise horizontal location and vertical elevation of all utility lines to be shown on a utility map. This task requires potholing of the existing pipelines using special soils vacuum system equipment. The cost associated with this task is estimated at $49,000.00. This project requires a permit from California Department of Fish and Game. The cost associated with this permit is estimated at $4,000.00. Reproduction cost is estimated at $2,500.00 THIRD AMENDMENT TO AGREEMENT CARSON REDEVELOPMENT AGENCY PARSONS Project No, 919: Wilmington Avenue Interchange Modification at the 1-405 Freeway. 7 EXHIBIT B Project No. 919- Wilmington Ave Interchange Modification at the 1-405 freeway An additional compensation not to exceed $179,652.93 to cover the costs for additional services reflected by exhibit "A" above, Original agreement $19804,200.00 First Amendment to the agreement - ---Second 96,972.21 Amendment tothe"agreemen t 329,732.98 Third Amendment to the agreement 1-7--9,652.93 TO FAL $2,410,558.12 THIRD AMENDMENT TO AGREEMENT CARSON REDEVELOPMENT AGENCY PARSONS Project No. 919: Wilmington Avenue Interchange Modification at the 1-405 Freeway.
