Report

Summary

The purpose of this project is to develop a new six-gate, two-level airport concourse at Terminal 3 (T3) of Phoenix Sky Harbor International Airport to accommodate operations for airlines, passengers and airport staff. The planned work will include an aircraft apron to accommodate six Airplane Design Group III aircraft that may service two Airplane Design Group V via two-for-one exchange; a connector bridge between the existing and new concourse to facilitate passenger movement with moving walkways; and one or more passenger bus lobbies at Terminal 4 north concourses to facilitate a passageway or tunnel for inter-terminal passenger connections between T3 and Terminal 4 (T4).

 

This amendment is necessary to facilitate additional design services for the Terminal 3 North Concourse 2 (T3N2), airside tunnel between T3 and T4, passenger level Video Wall and Mezzannine Level lounge, and associated Construction Administration and Inspection Services. This amendment will provide additional funds to the agreement.

The term of the agreement amendment remains unchanged at five years. 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.

The initial agreement for Architectural Services was approved for an amount not to exceed $30,700,000, including all subconsultant and reimbursable costs.

 

Amendment 1 to Agreement 158106 for Architectural Services increased the agreement by an additional $7,675,000, for a new total amount not to exceed $38,375,000, including all subconsultant and reimbursable costs. This amendment will increase the agreement by an additional $9,825,000, for a new total amount not to exceed $48,200,000, including all subconsultant and reimbursable costs.
