5. Please provide structural details for the concrete work at 64 Nowelo St, Hilo, HI 96720, including reinforcement for: Slab, Footings, Any placed concrete rebar Stamped drawings or engineer markups appreciated if available.

The concrete slab, footings, reinforcement, and carport anchorage are contractor-designed elements. Quoters shall include all required engineering, drawings, calculations, permits, and associated costs in their proposed price.

6. Please identify the applicable building-code editions and required site-specific structural criteria, including design wind speed, exposure category, risk category, seismic criteria, and allowable soil-bearing capacity. Please also confirm whether the contractor must provide Hawaiʻi-licensed, signed and stamped structural drawings and calculations for the foundation, reinforcement, anchorage, and carport connection.

Apply the federal, state, and local codes in effect at award. The Government has no separate site-specific structural criteria. No stamped drawings are required by the Government unless required for permitting.

7. Does the Government have geotechnical information, underground-utility drawings, surveys, or other subsurface information for the project location? If not, please identify the soil-bearing, base-course, and compaction assumptions bidders should use. Please confirm that materially different concealed conditions encountered after award will be handled under the Differing Site Conditions clause.

The Government has no geotechnical report, subsurface survey, or additional utility drawings. Base the proposal on ordinary competent soil, the specified 3/4-inch aggregate base, and standard concrete-industry compaction practices. Any materially different concealed condition will be handled by the CO under the applicable contract terms.

8. Please confirm whether one new carport base rail will be anchored to existing concrete and the opposite base rail will be supported by the new continuous footing. Has the Government verified the existing concrete’s thickness, reinforcement, condition, and capacity to support the new carport anchorage?

If the existing concrete is later found inadequate, please confirm that the additional corrective work will be addressed as changed work.

One base rail will anchor to existing concrete; the opposite rail will be supported by the new 60-foot footing. The Government has not independently tested the existing concrete. The contractor shall visually inspect and field-verify it before installation.

Unforeseeable deficiencies requiring work outside the stated scope must be reported to the CO before proceeding.

9. The SOW describes the new footing as 12 inches wide by 12 inches “high,” while the manufacturer’s instructions refer to a 12-inch-deep footing. Please confirm the intended minimum footing depth below finished grade and identify the minimum reinforcing-bar size, quantity, spacing, lap, and concrete-cover requirements bidders should include.

Bid the minimum footing shown in the SOW: 12 inches wide by 12 inches deep by 60 feet long, with a minimum concrete strength of 2500 psi. Provide No. 3 and No. 4 reinforcement as necessary to meet applicable code and accepted construction practices. The Government is not providing a separate rebar schedule or engineered design.

10. Please provide the anticipated operating weight, maximum loaded weight, and concentrated bearing loads of the 40-foot containerized laboratory. Please clarify whether container anchorage, tie-downs, embedded plates, corner-block connections, delivery, craning, setting, leveling, and securing of the container are included in the contractor’s scope or will be performed by the Government.

Container delivery, craning, placement leveling, tie-downs, and anchorage are not included in this contract. The contractor's scope is construction of the specified slab and moat and assembly of the carport. The anticipated operating weight of the

40-foot containerized laboratory is approximately 35,000-40,000 pounds. Offerors shall use 40,000 pounds as the maximum loaded weight for bidding and construction. The contractor shall account for the concentrated loading at the container's corner castings and longitudinal bearing rails. The completed 40-foot by 8-foot pad shall be level and sufficiently flat to provide uniform, stable support without rocking or twisting the container. The stated 6-inch slab thickness is the minimum; the contractor shall provide any additional reinforcement, localized thickening, or subgrade preparation necessary to support the stated load and comply with applicable codes and accepted concrete contrsuction practices. The contractor shall construct the slab to the required dimensions, elevation, flatness, and load capacity and shall leave it ready for subsequent container placement by the Government.

11. Will the Government provide a benchmark, finished container-pad elevation, precise slab and carport control points, and the required alignment relative to the existing building and carport? If not, please confirm that the contractor is responsible for establishing these through the required site layout and design.

The Government will identify the approximate slab and carport location during the site visit. The contractor shall field-verify dimensions, elevations, drainage, alignment with the existing carport, and final layout with the COR before beginning work. No surveyed benchmark is available.

12. Please confirm whether the new carport must be structurally connected to the existing carport or whether the connection is limited to a weather-tight roof transition. If structural attachment is required, please provide the required connection criteria and clarify responsibility for verifying the structural adequacy of the existing carport. Please also confirm whether the contractor may drill, cut, remove, or modify existing panels, trim, framing, or other carport components as necessary.

The new and existing carports are not required to function as one structurally integrated frame. The contractor shall provide a secure, continuous, weather- tight roof transition and flashing, trim, closures, fasteners, sealants. Limited drilling, cutting, or removal of trim and roof panels is permitted only as necessary for the connection and must be coordinated with the COR.

13. Please identify the exact roof edges requiring the specified fascia, continuous six-inch gutters, and six downspouts. Does this work apply only to the new 60-foot carport or to portions of both the new and existing carports? Please also identify the approved discharge locations and whether connection to underground drainage is required or whether above-grade extensions and splash blocks are acceptable.

Gutters and downspouts are required along the outside drainage edges of the combined roof area to prevent runoff onto the sidewalk and laboratory area. The six downspouts apply to the completed 120-foot roof system. Final locations shall be coordinated with the COR. Above-grade extensions and splash blocks are acceptable where they discharge away from the building, sidewalk, slab, moat, and erosion-prone area.

14. The moat must continuously retain at least four inches of water, but the project is located in a high-rainfall environment. Is a controlled overflow, drain, cleanout, or other means of preventing uncontrolled overflow required? If so, please provide the required discharge location and configuration.

The moat shall include a controlled drainage system for maintenance and cleaning.

Install a drain at the moat's lowest point with a removable strainer, normally closed valve, and capped outlet. The valve shall be accessible, clearly labeled, and secured against accidental opening. Drainage shall be directed through a hose or pipe to a Government approved collection or disposal location and shall not discharge directly to the ground, storm-drain system, or adjacent sidewalk.

15. For the potable-water connection identified in the previous RFI response, please provide the existing PEX pipe size and type, normal operating pressure, required backflow-prevention device, and any allowable shutdown windows.

Please also clarify whether wall or concrete penetration is anticipated at the identified tie-in point.

The source is the existing PEX line along the interior side wall of the existing building, approximately 15-20 feet from the moat. The contractor shall field- verify its size, pressure, precise tie-in point and required transition fittings. Concrete crossing or penetration is anticipated. Provide an accessible shutoff and any backflow protection required by code. Coordinate shutdown timing with the COR.

16. Please provide the normal work hours, facility-access or badging requirements, staging and material-storage limitations, shutdown restrictions, and any ongoing research operations that could limit excavation, concrete placement, lifting equipment, or carport erection.

Normal work hours are Mon-Fri, 7:00 AM to 3:30 PM, excluding federal holidays, unless otherwise approved. Coordinate site access, staging, material storage, excavation, concrete placement, lifting, and temporary shutdowns with the COR.

Maintain access to occupied research facilities.

17. Please confirm whether the Notice to Proceed will be issued before or after approval of the structural design, permits, and required submittals. If these activities must occur within the 90-calendar-day performance period, please provide the anticipated Government review duration for structural, product, and safety submittals.
