Report
Summary
Currently, the City of Phoenix is under contract with Kimley-Horn and Associates, Inc. for design services associated with the Dobbins Road Project. This Project will modernize Dobbins Road by widening the corridor with essential infrastructure upgrades. Resulting from an evaluation of project coordination between the Dobbins Road Project and a General Obligation (GO) Bond drainage project, a recommendation to combine project elements was identified for efficiency of labor and cost. The integration of these projects not only reduces the financial burden on the GO Bond fund, but also ensures a cohesive infrastructure design, minimizing potential conflicts during the construction phase.
Project Efficiency Analysis
The consolidation of the GO Bond drainage project (ST83140147) into the broader Dobbins Road Project scope provides significant fiscal and operational advantages. By integrating these efforts, the City expects to achieve the following:
- Design Cost Savings: approximately $700,000.
- Management Efficiencies: Project management fees will be streamlined through combined oversight.
- Technical Synergies: Additional savings are realized by eliminating redundant efforts in several key technical areas.
Kimley-Horn and Associates, Inc.’s services will include topographic surveying, utility coordination, two-dimensional flood modeling, hydraulic modeling, and the preparation of final construction documents.
Contract Term
The term of this amendment is three years from the issuance of the Notice to Proceed. Work scope identified and incorporated into the agreement prior to the end of the term may be agreed to by the parties, and work may extend past the termination of the agreement. No additional changes may be executed after the end of the term.
Financial Impact
The initial agreement for Engineering Services was approved for an amount not to exceed $1,847,573.87, including all subconsultant and reimbursable costs. This amendment will increase the agreement by an additional $600,000, for a new total amount not to exceed $2,447,573.87, including all subconsultant and reimbursable costs.
Funding for this amendment is available within the Street Transportation Department's Capital Improvement Program budget. The Budget and Research Department will separately review and approve funding availability prior to the execution of any amendments. Payments may be made up to agreement limits for all rendered agreement services, which may extend past the agreement termination.
