STATEMENT OF WORK

STRUCTURAL PEER REVIEW PANEL

Airport Traffic Control Tower (ATCT) and Terminal Radar Approach Control (TRACON)/ Base Building

Ted Stevens International Airport

Anchorage, Alaska

U.S. Department of Transportation Federal Aviation Administration

1.0 INTRODUCTION

The Federal Aviation Administration (FAA) intends to replace the existing Airport Traffic Control Tower (ATCT) (otherwise known as ANC ATCT) and Terminal Radar Approach Control (TRACON) facility (otherwise known as A11) at the Ted Stevens International Airport in Anchorage, Alaska. The 2016 Anchorage air traffic operations count was 278,000 for the ATCT and 270,000 for the TRACON.

The ATCT cab will be approximately 284 feet above ground level (AGL) and must be 650 square feet with 12 equally segmented sides. The ATCT shaft must be designed as a non-occupied shaft (no administrative or operational functions). The interior program space for the TRACON is approximately 25,000 square feet (SF).

A unique design is required for replacement ANC ATCT and TRACON due to the seismic hazards in Anchorage. It is critical the structural analysis and design is thorough and comprehensive and therefore, the FAA will utilize a Structural Peer Review Panel (SPRP) to verify the accuracy, completeness, and acceptability of the Engineer of Record’s (EOR’s) submittals.

2.0 STRUCTURAL PEER REVIEW PANEL

The SPRP must provide an independent, objective, technical review of design aspects that relate to structural performance, according to the requirements and guidelines described herein, and must determine if the design generally conforms to the intent of the International Building Code (IBC); ASCE 7, Minimum Design Loads for Buildings and Other Structures; Tall Buildings Initiative: Guidelines for Performance-Based Seismic Design of Tall Buildings (TBI); and the code requirements detailed in the Request for Proposal (RFP) Scope of Work.

The SPRP participation is not intended to replace quality assurance measures ordinarily exercised by the EOR in the structural design of a building. Responsibility for the structural design remains solely with the EOR, and the burden to demonstrate conformance of the structural design to the intent of the specified codes resides with the EOR. The EOR is solely responsible for the construction contract documents.

One member of the panel must serve as the review team chair, responsible for (a) mediating disputes, if any, between the reviewers, and (b) maintaining the peer review record and expressing the official positions and opinions of the review team. The review team chair must be a licensed structural engineer with expertise consistent with the panel members.

2.1 Qualifications and Selection of Panel Members

The SPRP will include three (3) engineers with recognized expertise pertaining to the following items:

(a) Earthquake hazard definition, and selection and modification of ground motions for use in nonlinear response history analysis, including effects of soil-structure interaction

(b) Behavior of structural systems, including foundations and supporting soils, relevant to the building under consideration when subjected to earthquake loading.

(c) Application of structural analysis software for use in nonlinear response history analysis and interpretation of analysis results.

(d) Expertise in the use of physical tests (e.g., wind tunneling) to develop structural analysis models and associated acceptance criteria.

(e) The requirements of the TBI Guidelines as they pertain to design of the type of structure under consideration.

The SPRP will be selected and contracted by the FAA based on their qualifications applicable to the Structural Peer Review of the project. SPRP members must bear no conflict of interest with respect to the project and will not be able to compete for the Architecture/Engineer (A/E) design contract. The SPRP will provide their professional opinion to and act under the instruction of the

FAA.

3.0 SCOPE OF WORK

The SPRP will aid the FAA in reviewing the A/E structural design scope prior to solicitation and provide consultation to the FAA during the A/E design competition. Members of the review panel may be required to attend meetings and presentations during the A/E structural design competition as advisors. After award of the A/E structural design, the SPRP will work with the EOR and FAA to compose scope of objectives based on the services listed below. The SPRP will review the A/E structural design for compliance and must include, but is not limited to the following:

(a) Basis of Design document, including the seismic performance objectives, the overall structural design methodology, and acceptance criteria;

(b) Proposed structural system and materials of construction;

(c) Earthquake hazard determination, and selection and modification of earthquake ground motions for application to the building model;

(d) Modeling approaches for structural materials and components;

(e) Structural analysis model, including soil-foundation-structure interaction as applicable, and including verification that the structural analysis model adequately represents the properties of the structural system within accepted norms for tall building designs;

(f) Review of structural analysis results and determination of whether calculated response meets approved acceptance criteria;

(g) Design and detailing of structural and non-structural components, including structural thermal isolation details

(h) Drawings, specifications, and quality assurance and inspection provisions in the design documents; and

(i) Any other considerations that are identified as being important to meeting the established performance objectives.

3.1 Peer Review Process

The peer review process will be initiated at the time of award and continue through the completion of the A/E structural design. The SPRP must accommodate FAA’s schedule to attend meetings, review documents, and provide feedback in a timely manner. Prior to the first design package review, a kick-off meeting with the EOR, the FAA, and the SPRP will be held to discuss the SPRP’s responsibilities, methods and lines of communication, and the design percentages and schedule for each milestone.

The review of structural submittals will begin with the Basis of Design and continue through the completion of the design. The SPRP is responsible for an in-depth review of the Basis of Design that summarizes the design objectives, methods of analysis, and acceptance criteria.

The SPRP must provide written comments to the EOR and to the FAA, and the EOR must prepare written responses thereto. Review duration and deadlines for retuning comments will be set during the kick off meeting. The SPRP must maintain a log summarizing peer review comments, EOR responses to comments, and resolution of comments with dates attached. The SPRP must make the log available to the EOR and to the FAA as requested. After the review of each design package (10%, 45%, etc.) or significant submittal, the SPRP will lead a design review meeting to discuss their comments and findings. The EOR is responsible for resolving all comments to the satisfaction of the reviewers.

At the conclusion of the A/E structural design review, the SPRP must submit a written report to the FAA that details the scope of their review, to include a comment log and the professional opinions of the SPRP on the design’s conformance to the A/E structural design requirements and guidelines. The FAA may request interim reports from the SPRP.

3.2 Dispute Resolution

If disputes arise between the EOR and the SPRP that cannot be resolved during the review process, dispute resolution will be the responsibility of the FAA. The FAA will provide resolution based on personal knowledge or may retain other experts to review the material and generate a recommended course of action.

3.3 Post Review Revision

If substantive changes to the A/E structural design occur during the design or construction phases, to the FAA may require additional review by the SPRP. Substantive changes include, but are not limited to changes in the seismic-force-resisting system configuration, design, detailing, or materials.

3.4 Post Design Services (Option 1 and Option 2)

After the completion of the design phase, the FAA may require the SPRP to provide onsite structural support during the construction phase. This work may include, but is not limited to, constructability reviews, structural observation and verification, review of shop drawings, etc. If the SPRP finds any work to be unsatisfactory or non-compliant with applicable codes or requirements during construction, they must bring it to the attention of the FAA immediately.

The role of the SPRP does not negate the responsibilities and duties of design structural EOR during the construction phase.
