Guam (ZUA) Airport Traffic control Tower Cab Replacement

JCN: 20012097

1. PROJECT DESCRIPTION:

This is a “Design-Build” project to replace the existing Federal Aviation Administration (FAA) owned Guam (ZUA) Air Traffic Control Tower (ATCT) Cab complete with new structural components and architectural features, to include new roofing system, windows and window washer sprinklers, and slat-wall consoles. The replacement will be based on the existing approximate square footage of 166 square feet with eight column supports.

The FAA acquired the existing facility from the US Navy after the 1995 Base Realignment and Closure (BRAC). The Guam ATCT Tower/Cab and adjoining Center Radar Approach Control (CERAP) facility were constructed in the 1950s and has gone through various modifications including the addition of an exterior flight of stairs from the 5th Floor to the Cab, see Figures 1 and 2.

Figure 1 CAB and Enclosed Exterior Stairs Figure 2 CERAP and CAB

The Cab structure has suffered from severe corrosion from the extreme environmental effects of the salt air that has infiltrated into the Cab window framing and structural supports. Replacement will meet current codes and will address the increasing wind and seismic events.

2. PROJECT LOCATION:

This project is located at the FAA Guam CERAP (ZUA),1775 Admiral Sherman Blvd., Barrigada, GU

96913-1612 USA.

3. SCOPE OF WORK:

Provide all necessary labor, materials, transportation, equipment, and supervision, engineering design, certifications, permits and other incidental work required for this project.

Other incidental work required includes all items and considerations necessary to ensure a complete and usable final product, including, but not limited to, the necessary design and construction considerations not specifically stated elsewhere in this statement of work. Complete and usable final product means that the completed final product can be used to fully satisfy the requirements and the intended purpose of the project.

The existing line of sight (LOS) and eye elevation height will be designed to the current elevation. The Cab windows will be designed to the current dimensional shapes and angle. The mullions and roof support are internal structures to the Cab and will be assumed that they too will be designed similarly. These are attached to the 10” concrete wall, atop of the 5th Floor Roof, see Figure 3.

Figure 3, 10” Concrete Wall

The Design-Builder will be required to submit an Architect-Engineer Qualification Standard Form 330-

Pre-proposal Site Survey – It is highly recommended that all interested Design-Builder Contractors attend a pre-bid site survey at the Guam ATCT to see firsthand the condition of the facilities, and the conditions under which the construction work will need to be completed. The pre-bid site survey date(s) is scheduled for October 30 and 31, 2024. Both days are available. Questions arising from the pre-bid survey must be submitted to the FAA CO within ten (10) business days. FAA will consolidate and address all questions, then disseminate the final responses to all the bidders. Bidders that choose not attend the post-site survey conference do so at their own risk and may miss valuable information.

Facility Drawings – A number of existing facility drawings (PDF format) are included with this SOW and photographs are subdivided into three separate categories Site Drawings, as-builts and redrawn (Attachment J-2), Photographs from previous survey conducted on ATCT Cab windows noting the corrosion Building (Attachment J-3), and Guam ATCT Presentation (Attachment J-4); however, some drawings may contain information for more than one category. The drawings contain information pertaining to the building envelope work included in this call order. While the drawings generally depict the existing conditions, some of the drawings are old and likely outdated; therefore, the Design- Builder Contractors are hereby cautioned that some of the information/details may not be completely accurate. The pre-bid site survey may be used to validate the information contained in the provided drawings. If some information cannot be validated via visual inspection during the pre-bid site survey, each Design-Builder contractor shall make and document their assumptions. If it turns out that the successful bidders’ assumptions were incorrect, a contract modification will be issued by FAA to address the differing conditions.

11. PERFORMANCE PERIOD:

Normal work hours are between 7:30 a.m. and 4:30 p.m., Monday through Friday, excluding Federal Holidays. No work will be performed outside normal duty hours unless authorized in writing by the

Contracting Officer. Any work outside normal work hours must be requested at least 3 days in advance.

Total performance period is 300 calendar days commencing on the date of contract award. Full cessation of ATCT Cab operations shall only be authorized for a maximum of 120 calendar days to allow the removal of existing tower Cab and installation of the new tower Cab where lowest operational impact occur. The Performance Period includes all required design, reviews, approval of final design, procurement of long lead materials or items, construction, testing, corrections, if required, final testing, acceptance, and other requirements necessary to deliver a complete and usable ATCT Cab.
