STATEMENT OF WORK (SOW)

Project Title: Billboard Structure Procurement and Installation

1. Project Overview

1.1 Objective

Turnkey procurement, structural engineering, delivery, and installation of a freestanding billboard framework designed to support aluminum panels, including UFC-compliant concrete pad construction.

1.2 Location

181st Intelligence Wing, Terre Haute Air National Guard Base 800 S Peterchef St.

Terre Haute, IN 47803

1.3 Period of Performance

Negotiable. Contractor to propose timeline required to procure and install.

2. Technical Specifications The contractor shall ensure all materials and installations meet the following exact structural and physical criteria:

· Display Area Dimensions: 32 feet (width) by 12 feet (height).

· Ground Clearance: The bottom edge of the structural framework shall sit no higher than 1 1/2 feet above finished grade.

· Concrete Pad Geometry: A ground-level concrete pad must outline the perimeter of the billboard structure, featuring a one-foot offset extending outward from all outer edges of the billboard's footprint.

· Concrete Pad Finish: The surface must be finished to a flat, smooth, level profile (such as a hard steel trowel finish) to facilitate the future bonding and adherence of brick and mortar.

· Concrete Compressive Strength: Minimum 4,000 PSI compressive strength at 28 days, strictly conforming to UFC 3-301-01 and ACI 318 structural standards for exterior slabs on grade.

· Concrete Durability & Mix: Air-entrained concrete (5% to 7% air content) to withstand localized freeze-thaw cycles and weather exposure.

· Steel Reinforcement: Reinforced with ASTM A615, Grade 60 deformed rebar or structural welded wire reinforcement (WWR) as designated by structural wind-load engineering.

· Subgrade Preparation: Compacted base/subgrade quality matching UFC 3-250-04 parameters to prevent slab cracking, settling, or shifting.

· Panel Mounting Capacity: Framing designed to securely and seamlessly affix twelve (12) factory-coated aluminum panels (4' x 8' dimensions, 1/4" thickness) with zero structural warping. See Figure 1 for further dimensional details.

· Wind Loading: Structural framing and foundation must be engineered to withstand regional wind loads per UFC 3-301-01 (referencing ASCE 7 structural design loads).

3. Scope of Work & Deliverables The contractor is responsible for completing all actions within the following project phases:

Submittals Submit structural drawings detailing concrete pad dimensions, reinforcing steel schedules, footing depth, and wind load compliance matching local parameters.

Construction Clear utility conflicts, excavate the designated area, prep the subgrade per UFC standards, build the formwork, place the Grade 60 steel reinforcement, and pour the 4,000 PSI concrete pad with the required 1-foot offset. Finish the concrete surface to a flat, smooth trowel finish ready for masonry work.

Procure and deliver the structural framing, mounting brackets, and hardware to the site location.

Securely install the billboard framework. Verify that the maximum ground clearance does not exceed 1 1/2 feet.

Completion Conduct final clean-up, strip concrete forms, dress the soil around the new concrete pad, and perform a joint final quality inspection with the Contracting Officer Representative.

4. Contractor Responsibilities & Quality Control

4.1 Quality Testing

The contractor must provide concrete delivery tickets verifying the mix design meets the 4,000 PSI minimum and is air entrained. Field slump and cylinder break tests may be requested by the Government inspector.

4.2 Safety Compliance

Adhere to all OSHA safety rules and Department of War based-specific industrial safety standards.

4.3 Warranty

Provide a comprehensive warranty covering concrete cracking/spalling, structural steel deformation, and foundation shifting.
