3. Please confirm whether the reinforcement, footing, slab, and anchorage requirements are fully prescribed in the contract documents or whether the contractor is responsible for engineering, design verification, or preparation of any additional structural details.

The attachments provide manufacturer component information and identify the supplied anchorage hardware, including 3/8-inch by 3¾-inch concrete wedge anchors and Z-clip base-rail anchors. However, the attachments do not constitute a complete site-specific structural design for the footing, slab, reinforcement, or anchorage system.

The dimensions and requirements in the SOW are minimum requirements. The contractor shall:

• Follow the Absolute Steel assembly instructions and applicable drawings;

• Verify that the foundation and anchorage are compatible with the supplied carport components;

• Verify that the supplied anchors are appropriate for the concrete thickness, edge distances, embedment, spacing, and site conditions;

• Verify compliance with applicable wind, seismic, structural, and building-code requirements; and

• Provide additional structural details or Hawaiʻi-licensed engineering when required by code, permitting authorities, or the manufacturer’s installation requirements.

Any proposed substitution or modification of the manufacturer-supplied anchors or structural components requires Government approval before installation.

4. Please identify the intended source and tie-in location for the required 1-inch Schedule 40 PVC water line.

The contractor shall connect the one-inch Schedule 40 PVC water line to the existing potable-water PEX line running along the interior of the East-facing side of the building. The approximate distance from the existing PEX line to the moat spigot is 15-20 feet.

The contractor shall provide all labor, equipment, fittings, valves, and materials necessary to:

Verify the existing water source, pressure, pipe size, and connection method;

Connect the new one-inch PVC line to the existing PEX water line using an approved transition fitting;

Provide an accessible shutoff valve at or near the source;

Route the water line from the identified source to the moat spigot;

Penetrate, saw-cut, or otherwise cross existing concrete as necessary;

Install and securely support the moat spigot at least 12 inches above the finished concrete;

Install the pipe on appropriate sand bedding and protect it beneath the slab;

Pressure-test and flush the completed line;

Provide code-required backflow protection;

Restore all disturbed concrete and other surfaces to their original condition; and Obtain any required plumbing permits and inspections.
