AI Contract Overview

The contract involves a Construction Management At Risk (CMAR) project focused on modernizing terminal restrooms and making other improvements at Ontario International Airport, one of the fastest-growing airports in the United States. The project aims to enhance key passenger facilities while maintaining uninterrupted terminal operations in an active airport environment. This requires early collaboration between the airport authority, design consultants, and the construction manager to develop phased construction strategies that minimize disruptions to passengers, tenants, and overall airport operations.

Full Description

ONT is one of the fastest-growing airports in the United States. This continued growth, combined with the need to maintain uninterrupted terminal operations, requires a delivery approach that emphasizes early coordination, constructability input, and careful phasing to support both passenger experience and operational continuity. The Program will modernize key passenger facilities while work is performed within an active, occupied airport and terminal environment. The Program will require close collaboration between the Authority, its design consultant(s), and the CMAR to develop efficient phasing strategies, manage operational constraints, and mitigate impacts to passengers, tenants, and airport operations. Through the CMAR delivery method, the Authority seeks to engage a qualified construction partner early in the design process to provide preconstruction services, including cost estimating, constructability reviews, scheduling, logistics planning, and risk identification. This collaborative approach supports informed decision-making, cost certainty through the establishment of one or more CGMPs/GMPs, and successful execution of construction activities. The CMAR will be expected to manage a range of work activities associated with the Program, including coordination with specialty subcontractors as necessary to address site-specific and operational requirements.
