3.0 Purpose

The contractor shall provide all labor, supervision, professional services, equipment, tools, transportation, testing, and materials necessary to construct a reinforced concrete foundation for a government-furnished 40-foot-long by 8-foot-wide containerized laboratory and to install one government-furnished 18-foot-wide by 60-foot-long pre-fabricated metal carport to the existing carport to create a continuous roof system approximately 18 feet wide by 120 feet long. The completed work shall be weather-tight, structurally sound, code-compliant, and ready for government use.

3.1 Background and site: The work will be performed at the Daniel K. Inouye US

Pacific Basin Agricultural Research Center located at 64 Nowelo St in Hilo Hawaii.

The containerized laboratory will support the rearing of insects imported under an APHIS Controlled Import Permit. The foundation therefore includes a continuous water moat surrounding the container footprint. Hilo’s high rainfall, wind exposure, humidity, and corrosive environment shall be considered in material selection, drainage, fastening, and installation. Figure 1 shows the proposed site location.

3.2 Design verification and submittals: Before construction the Contractor shall verify that the proposed foundation, footing, reinforcement, anchorage, structural connections, and roof continuity are compatible with the government furnished carport manufacturer’s requirements and applicable site-specific conditions.

• Site layout showing the slab, moat, sidewalks, carport, footing, downspout discharge locations, and relationship to existing improvement.

• Concrete mix design; base-course material and compaction requirements;

reinforcement plan; jointing and curing plan; proposed moat waterproofing system.

• Carport manufacturer’s installation documents; engineered anchorage details, connection details for joining the new and existing carports, and corrosion-resistant fastener specifications.

• Product data and color selection for fascia, gutters, downspouts, sealants, coatings, and other exposed materials.

• Grounding and bonding plan identifying proposed improvements and test methods.

• Work schedule, site-specific safety plan, and required permits/approvals.

3.3 Subgrade, base course, and earthwork:

• Strip unsuitable or organic material and grade the work area to the required lines and elevations.

• Provide excavation, structural fill, and compaction necessary to support the slab, footing, and sidewalks without settlement.

• Install a compacted ¾-inch aggregate base coarse beneath the concrete.

Thickness and compaction shall comply with the approved design, geotechnical or code requirements, and concrete industry standards.

• Set the finished elevation high enough to prevent water runoff from entering the containerized laboratory. Grade adjacent surfaces to drain away from the slab and building while maintaining required accessibility and safe transitions.

• Locate existing underground utilities before excavation and coordinate conflicts with the site POC before proceeding.

3.4 Concrete slab, raised container pad, and water moat: Construct a reinforced concrete assembly with the following dimensions. The contractor shall verify the resulting overall footprint and reconcile any conflict with site conditions before placement. The nominal outside footprint is approximately 47 feet by 15 feet: a 40-foot by 8-foot container pad, a 6-inch-wide moat on all sides, and a 3-foot-wide perimeter sidewalk outside the moat.

• Slab and sidewalk thickness: minimum 6 inches.

• Concrete strength: minimum 2500 PSI.

• Reinforcement: welded wire reinforcement.

• Finish: level where required for container; uniformly brush-finished to prevent slipping. Edges shall be tooled and exposed corners finished.

• Raised pad: inner area of 40 ft x 8 ft elevated by 2 inches above the adjacent perimeter walking surface.

• Water moat: Continuous moat around all four sides of the raised pad. The moat shall be 6 inches deep x 6 inches wide and shall retain at least 4 inches of water without leakage (see Figure 2).

• Waterproofing: Form or coat the moat with solid, continuous, impervious, waterproof material suitable for permanent exterior immersion, UV exposure, and anticipated cleaning. Seal joints and penetrations with compatible material.

• Perimeter sidewalk: Provide a 3-foot-wide concrete sidewalk outside the moat around the full perimeter. Maintain positive drainage away from the laboratory.

• Joints and curing: provide construction, control, and isolation joints and cure concrete in accordance with the approved placement plan and applicable industry standards.

3.5 Moat water supply rough-in:

• Install a 1-inch Schedule 40 PVC water-supply pipe beneath the concrete slab. Protect the pipe with a sand base layer during concrete placement.

• Terminate the interior end within the moat area with an accessible riser and hose bib or spigot. The riser shall extend at least 12 inches above the finished concrete surface and shall be securely supported.

• Extend the supply end at least 6 inches beyond the outside edge of the concrete and install a watertight temporary cap until a water source is provided.

• Pressure-test the piping before concealment and provide the test result to the government. Photograph the installed route before concrete placement.

3.6 Carport footing and anchorage: The government furnished metal carport requires continuous footing along the side not supported by existing concrete (see Figure 3).

The nominal footing dimensions are 12-inch-wide x 12-inch-high x 60-feet-long.

• Provide a properly prepared and compacted aggregate base beneath the footing.

• Provide reinforcing steel, including No. 3 and No. 4 bars where appropriate.

• Provide concrete with a minimum 28-day compressive strength of 2,500 psi, or greater where required.

• Provide embedded anchors, base plates, isolation materials, and corrosion protection compatible with manufacturer’s requirements.

Figure 3. Existing carport of the same style/size that will need to be connected to the new carport and will require installation of gutters and downspouts to prevent rain runoff onto existing sidewalk.

3.7 Carport assembly and roof connection:

• Inventory government-furnished metal carport and roof components before installation. Promptly report any missing, damaged, incompatible, or insufficient components.

• Install the 18-foot by 60-foot pre-fabricated metal carport in accordance with the manufacturer’s instructions.

• Connect the new carport to the existing carport of the same nominal style and size to create a continuous roof surface approximately 120-feet-long by 18-feet-wide (see Figure 3).

• Flash, seal, overlap, and fasten the connection so that it is structurally secure and weather-tight. Use fasteners, closures, sealants, and dissimilar-metal isolation materials suitable for Hilo’s wet, corrosive environment.

• Provide all miscellaneous clips, closures, trim, flashing, sealants, fasteners, and accessories required for a complete installation whether or not individually listed.

3.8 Fascia, gutters, and downspouts:

• Provide nominal 2-inch by 6-inch exterior-rated, preservative-treated wood fascia boards suitable for Hawaii’s wet and termite-prone environment. Treat field cuts and penetrations and coat exposed wood with an exterior protective finish.

• Provide continuous 6-inch-wide corrosion-resistant metal rain gutters along the designated roof edges. Select gutter profile, metal, gauge, brackets, and spacing to accommodate the contributing roof area and local rainfall without overflow under normal design conditions.

• Provide six 4-inch nominal-diameter ultraviolet resistant PVC downspouts, including fittings, straps, outlets, and transitions. Securely support all downspouts.

• Locate and discharge downspouts so runoff does not flow onto existing sidewalk, concrete foundation, moat, building, equipment, or areas subject to erosion. Provide splash blocks, extensions, or connections to an approved drainage point as required by layout.

• Slope gutters to drain; seal joints and end caps; and water-test the completed gutter system.

3.9 Grounding and bonding: A qualified electrician shall inspect the existing conditions and provide the grounding and bonding improvements necessary for safe, code-compliant operation of the metal carport and associated electrical system. Bond metal components as required, protect connections from corrosion, and test the completed grounding system.
