Anchorage International Airport Concourse A & B Renovations Phase 2

The Ted Stevens Anchorage International Airport "South Terminal Seismic & Security Retrofit Phase 2" consists of a 300,000 sf remodel and retrofit of the A & B Concourses and the remaining portions of the Main Terminal not completed in Phase 1.  The scope of work included abatement of hazardous materials and demolition of portions of the existing structure, seismic upgrades, interior and exterior architectural finishes, roofing, and mechanical and electrical system upgrades and the installation of a state-of-the-art baggage handling system.  The upgrades were designed to bring the terminal and systems up to code, and to revise the architectural aspects to more closely match the C Concourse.

Longer Description

Preconstruction services on the TSAIA Seismic and Security Retrofit started with the cohabitation of our Construction Manager in the offices of the Architectural Design Consultant. Working in-house with the Architect allowed for a constant flow of information during this critical time in the life of the project. In addition to weekly stakeholder meetings, construction work plans, feasibility reviews, pre bid solicitations, subcontractor prequalification packets and review, the following preconstruction services performed on this project helped make significant impacts in both cost and scheduling savings.

Phasing Analysis - The overall project phasing plan was critical to our success. PCL evaluated and identified eight different phasing options and relocation plans. The single most significant cost savings revolved around a thorough understanding and examination of the airline parking layout and the actual gate usage. PCL demonstrated that 8 to 9 gates could be closed at a time instead of 2 to 4, which opened up a larger work area for construction. This finding lead to decreased disruption on the project, huge cost savings and a significant decrease in the schedule duration.

Detailed Existing Conditions Review - During the schematic design stage on the TSAIA project, a detailed study was conducted by PCL to find the most economically feasible locations for seismic braces, so existing access ways, passenger boarding bridges, fuel lines and other utilities would not have to be relocated. This strategic study evaluated different seismic methods of strengthening the building, their costs and the costs of the relocation of existing utilities, etc. Ultimately the most economical solution was implemented.

Document Reviews - PCL identified a discrepancy between the structural column size and the size of the architectural column wraps months in advance of their procurement. This allowed enough time for them to be resized and the adjacent finishes to be adjusted. Had PCL’s continuous drawing reviews not identified this conflict as early as it did, the column covers would have had to been re-purchased in order to cover the structure. In addition, the soffits would have had to been rebuilt to receive the new column covers. This finding saved time and cost to the overall project.
