Executive Summary:

NAVFAC Atlantic completed preliminary site investigations at multiple Marine Corp Air Stations due to prior failures of Vertical Lift Fabric Doors (VLFD). The investigations identified the need for the following:

1. Repair by replacement of several critical door components.

2. Performance of additional comprehensive inspections by individuals with expertise in the design, construction, and operation of Vertical Lift Fabric Doors.

MCAS New River / Building AS890 has been identified as a facility requiring this work. This Executable Scope focuses on the following with detailed scope descriptions for each included herein under Scope of Services section:

1. Inspect and Analyze Lift Arms

2. Replace Door Wire Rope Lifting Cables

3. Replace Door Guide Roller Assemblies

Refer to the Price Schedule attachment for Base Price and Option Items.

Performance of additional comprehensive inspections, O&M preventative maintenance service, additional maintenance service, door tilt sensor testing and other related work will be accomplished later by the government after completion of the work identified in this scope.

Hazardous Materials Notes:

1. Hazardous materials testing has not been conducted at the facility. The scope of work is not expected to disturb hazardous materials, if present. Report discovery of hazardous materials to the Contracting Officer immediately.

2. Dispose of materials, whether hazardous or non-hazardous, in accordance with applicable federal, state, and municipal laws, rules, and regulations, and as directed by the installation hazardous waste/water media managers.

General Notes:

1. Dispose of items indicated for removal offsite unless otherwise noted.

2. Provide new materials unless specifically noted as existing to remain or as provided by the Government.

3. Field verify existing conditions and dimensions prior to proceeding with the work.

4. For bidding purposes, assume sequence of work will be Module D, Module A, Module B, and lastly Module C. Refer to VLFD Number Key attachment.

5. Comply with Marine Corps Order (MCO) 3070.3 regarding Personal Portable Electronic Device use near flightline. Personal portable electronic devices including cellular phones, laptop computers, tablets or e-readers, smart watches, digital cameras or camcorders, and other devices with the capability to store, record, and/or transmit text, images/video, or audio date are prohibited from areas that are actively involved with Marine Corps aviation operations: the hangar, the flightline, aircraft maintenance spaces, briefing areas, and in the aircraft. Submit request for exceptions to this policy to the Contracting Officer for routing to appropriate reviewers/approvers. Unless approved by the Contracting Officer, request COMMSTRAT Marines on-base to take photos/video required to complete the scope of work.

Scope of Services:

1. Inspect and Analyze Lift Arms

A. The purpose of the inspection and analysis is to ensure the Lift Arms, where attached to the mullions, are not defective or damaged and are structurally capable of resisting the forces imparted to the lift arms during the operation of the doors.

Follow steps in O&M manual for inspection procedures including the following:

a. Verify that mullion operation is smooth and unobstructed.

b. Verify that electric winch and chain-fall for mullion are fully operational.

c. Visually inspect Lift Arms, including attachment to the mullion.

B. Prepare a written report to document and include the following:

a. Defects and damage identified during the inspection

b. Results of structural analysis

c. Information on inspection with a detailed description of the defect or damage and details of the structural analysis

d. Recommendations for corrective action, if any, with cost and timeline to execute

C. Upon MCICOM and Navy review of the report, the Contracting Officer may negotiate a contract modification for some or all recommended / required corrective actions.

2. Replace Door Wire Rope Cables

A. Visually inspect the existing wire rope cables and connections to become familiar with existing conditions prior replacing components. Prepare a written report to document conditions.

B. After completing visual inspections, replace wire rope cables on each door panel regardless of condition.

1) Replace wire ropes in kind to match nominal diameter, wire rope type, material standard, and wire rope grade.

a. General description of wire rope is standard type used for crane service.

b. Hot-dip galvanized non-rotation-resistant crane-type wire rope.

2) Use a swaged termination with 90% or higher connection efficiency at lower connection to door truss.

3) Reuse existing steel thimbles from door truss, where present. Swaged termination may need to be installed with steel thimble in place (Contractor to verify).

4) Use a termination compatible with the existing drum with 90% or higher connection efficiency at upper connection to drum.

5) Field-verify the wire rope’s upper termination type at the drum / motor / gearbox.

6) Inspect the removed wire rope cables for damage / wear and document results of inspection.

3. Replace Door Guide Roller Assemblies

A. Visually inspect the Door Guide Roller Assemblies (Beam Guide Roller Assemblies and Bottom Beam Guide Rollers) to become familiar with existing conditions prior to replacing. Prepare a written report to document conditions.

B. After completing visual inspections, replace, in kind, Door Guide Roller (Beam Guide Roller Assemblies and Bottom Beam Guide Rollers) regardless of condition. Door manufacturer (International Door, Inc.) Part Numbers are as follows:

1) Beam Guide Roller Assemblies: 16A-R and 16A-L

2) Bottom Beam Guide Rollers: 16B-R and 16B-L

Warranty:

1. Provide a three-year warranty for new mechanical and electrical components against defects in material and workmanship beginning on the date of Project Acceptance. The manufacturer is responsible for items requiring adjustment, repair or replacement for the three-year maintenance-free warranty period, or 1500 door cycles, whichever occurs first, as counted by the door close limit switch.
