STATEMENT OF WORK

Corrosion Control, Coating, and Reflector Panel Fabrication for AN/FSC-78 Terminal in

Guam

1.0 INTRODUCTION

The NRL Code 8124 requires the corrosion control, coating, and reflector panel fabrication for one AN/FSC-78 terminal in Guam.

2.0 SCOPE OF WORK

This Statement of Work (SOW) defines the work effort associated with the required corrosion control, coating, and reflector panel fabrication for one AN/FSC-78 terminal in Guam. The contractor shall independently perform all work and furnish all labor, materials, supplies, equipment, and services to perform the services detailed in Sections 2.1 through 3.0.

2.1 CORROSION CONTROL AND COATING

The scope of work defined in this document is limited to removing any contaminants from the exterior surfaces of the antenna structure including mildew, grease, oil, algae, and other deleterious foreign matter in accordance with SSCP-SP 12 / NACE No. 5, as applicable, repairing superficial damage to those surfaces, and applying a coating system that will protect the antenna surfaces for an extended period of time. In this Statement of Work, superficial surface damage is defined as surface rust and/or peeling paint. It also includes the severely corroded sections of the antenna drum which shall be removed and replaced with new sheet metal where required. This SOW does not address structural corrosion. Structural corrosion is defined as corrosion affecting the integrity of the structure, and logically would require repair or replacement of the structurally corroded portion, itself.

The contractor will be responsible for shipping and handling of all tools, equipment, and potentially hazardous materials required to complete the work.

The place of performance for the corrosion control and coating shall be the location of the one AN/FSC-78 terminal in Guam.

The period of performance for the corrosion control and coating shall be 1 July 2026 – 31 December 2026.

2.1.1 AN/FSC-78 TERMINAL

The exterior surfaces of the AN/FSC-78 terminal include, and are limited to: 1) Reflector support assembly (quadripod, crow’s nest, reflector hub), 2) Ring Girder, 3) elevated Equipment Room (EER) exterior and interior 4) Elevation Wheel and Yoke Assembly, 5) Ladders, stairways, and platforms, 6) Azimuth cone assembly and 7) concrete base. The antenna reflector shall be cleaned but not painted.

The scope of work is that which would be expected of a refurbishment and painting subcontractor. It does not include “putting right” or repairing any components on the antenna.

An example would be the repair or replacement of structurally corroded fasteners or electrical boxes. It does; however, include those tasks described in Section 2, “Surface Preparation Tasks.”

Since surface preparation is limited to preparing the surfaces for painting, as opposed to entirely removing previous coatings, an epoxy mastic system is specified in this SOW. This SOW also specifies the contractor apply a brushed epoxy coating to all deteriorated areas (most commonly found on sharp edges, crevices, weld seams, back-to-back angles and hardware). The process is described in Section 2.1.3

2.1.2 SURFACE PREPARATION TASKS

1. The contractor shall perform the following surface preparation activities prior to touch-up painting:

a) Initial pressure wash all exterior surfaces to remove accumulated mildew, grease, oil, algae, and loose paint, and use a surface cleaner product to provide a clean surface prior to touch-up painting.

b) Removal of any remaining surface corrosion and loose paint by mechanical means, which may include sanding, grinding, or other similar methods.

c) Removal of all evidence of the exterior surface corrosion and recoat as necessary.

2.1.2a REMOVAL OF PAINT CHIPS

The subcontractor shall be responsible for the containment, collection, removal, and disposal of paint chips, or otherwise, in accordance with all EPA requirements. All paint chips and residue will be vacuumed and placed in marked 55-gallon drums for disposal. All processes for the preparation of surfaces and the application of all coatings, including all materials and products used, shall meet all EPA and local requirements.

2.1.3 CORROSION CONTROL AND COATING PROCESS DESCRIPTION

1. The subcontractor’s process shall be designed to ensure the following results:

a) Adequate repair of the existing finish damage.

b) A high probability of compatibility with the existing finish.

c) Applicability to steel, aluminum, hot-dip galvanized steel surfaces and concrete surfaces.

d) A durable finish with an extended time until such time as the next full recoating will be required.

e) Environmental safety.

2. Surface Preparation

a) The subcontractor shall pressure wash to remove dirt, dust, mold, mildew, loose paint, oil, grease, and other contaminants in accordance with SSPC-SP 12 / NACE No.5, as applicable.

b) Corrosion control utilizing SSPC-SP 15 (Bare Metal Power Tool Cleaning). SSPC-SP

14 / NACE No. 8 (Industrial Blast Cleaning) where feasible and permitted. Careful cleaning and surface treatment prior to all painting operations cannot be over-emphasized. This factor is of prime importance in obtaining a satisfactory paint finish. Cleaning shall be done with solvents, detergents, and processes that have no deleterious effect on the surface and that produce a surface satisfactory for receiving subsequent finishes. Loosely adhered paint and superficial rust shall be removed by pressure washing.

c) Dirt, grease, loose chalky paint, or other foreign material that have accumulated on the previously painted or galvanized surfaces shall be removed with a pressure washing or steam cleaning apparatus, which shall precede all other phases of cleaning. It is not intended that sound paint be removed using this process. Any paint that becomes loose, curled, lifted, or loses its bond with the preceding coat or coats after pressure washing shall be removed to sound paint or metal surface level by other means. Hand and power tool cleaning should then be used to abrade remaining intact coatings and establish an anchor profile suitable for subsequent coatings.

d) Application of a Sealer Coat.

(1) A epoxy penetrating sealer shall be applied to prepared surfaces as necessary to assure compatibility with the existing coatings and to seal all damaged areas.

This sealant shall be applied by brush.

e) Application of a two part Epoxy.

(1) Application of a Direct-to-Rust (DTR) fast-cure polyamide epoxy primer, approximately 7 mils DFT, on all compromised metals to ensure corrosion protection. All sharp edges, weld seams, skip welds, bolts, crevices, and back-to-back angles where the existing coating has deteriorated will be brushed coated.

Once DTR is applied a Direct-to-Metal acrylic topcoat paint is used. The application of this coat shall be all that is required to provide adequate finish protection to the touchup areas for at least four to five years.

f) Topcoat application.

(1) The application of a Direct to Metal (DTM), white, high-performance acrylic topcoat, approximately 5-7 mils DFT, to all exterior antenna surfaces excluding the reflector, by whatever means suitable to the site conditions.

2.1.4 CORROSION CONTROL AND COATING PRODUCT DATA

a) The following is a suggested list of products. The contractor shall be allowed to use alternate paints, primers, or washes, as long as they are equal or better in quality, environmental conformance, and properties to the items specified here.
