Q09: The provided drawing (atachment 2) calls for a New Service Disconnect. Please confirm that this is a disconnect for the equipment and not a New Service Disconnect.

A09: confirmed. This is intended to be a service disconnect for the equipment. Per the SOW, contractor shall provide/install electrical panels, switches, and connec�ons needed to power control cab, distribu�on box, electrical starter unit, and fuel system as shown on the atachments.

Q10: Op�on 003 call for the installa�on of approx. 1000’ of fiber to building 15437. Can the government confirm that there is a spare innerduct and adequate space in the exis�ng raceway from MH237A all the way to the communica�ons hub in Building 16430?

A10: For op�on Bid Item #2 the government confirms that there is space in the innerduct from building 16430 to MH E237A. The contractor will be responsible for installing innerduct from the manhole to bldg. 15437.

Q11: Please confirm if structural drawings will be required for the canopy and concrete foo�ng and stamped by an Alaska engineer?

A11: The government confirms that new structural drawings need to be stamped by a Professional Engineer.

Q12: Please confirm that no soil analysis is needed for the concrete pad and foo�ngs and that the new concrete pad and foo�ng will reside on compacted na�ve soil.

A12: To be determined by the contractor.

Q13: Please indicate any test requirements for concrete, compac�on, welds, cabling, or other special inspec�ons.

A13: All work shall be in accordance with UFC criteria, building codes, local direc�ves, and standard prac�ces.

Q14: Please confirm that the Instrumenta�on and Control Cab with dimensions of 8’x8’x20’ is not part of the equipment to be placed on the new concrete pad.

A14: The government confirms that the control cab will not be placed on the new concrete pad. The new concrete pad is intended to support the fuel skid.

Q15: Please confirm that the proposed loca�on of the concrete slab and foo�ngs will not impact the exis�ng building concrete foo�ng.

A15: The government confirms that the concrete foo�ngs and slab are not intended to �e into or impact the exis�ng building founda�on. The contractor is responsible for ensuring new founda�on and canopy systems do not degrade the exis�ng structure.

Q16: Please confirm if mil cer�fica�ons will be required for canopy and rebar.

A16: No requirement.

Q17: A painted plywood board with ground connec�on and 4” PVC pipe in the floor is next to a steel column on the North Wall. Please indicate if this is the loca�on for the new Comm Panel.

A17: Use of the exis�ng plywood board for the new comm panel is acceptable.

Q18: Please confirm that a new 4” PVC pipe will need to enter the building in proximity of the exis�ng, through the concrete founda�on and that the concrete slab will need cut and removed for this and new concrete placed back for slab will need rebar doweled and concrete painted to match?

A18: The government confirms that this is an acceptable loca�on and method for installing the new innerduct building entry. The government notes that op�on bid #1 requires the installa�on of two (2) 4” PVC ducts.

Q19: Please confirm if new electrical conduit will need to install behind interior metal paneling.

A19: No requirement.

Q20: One of the duct openings that was laid out with blue tape is in the path of the building brace rods. Please confirm if this opening can move up without interfering with steel girts above. If moving the opening up interferes with the steel girt can the steel girt loca�on be altered, and will this require any modifica�ons to the structure of the building? Also, will the exterior metal siding panels need replaced due to exposed fastener holes?

A20: The loca�ons of the vents and service disconnect are es�mates. Openings may be adjusted to allow for clearance from building structural systems. If contractor’s solu�on creates exposed fastener holes, the contractor will submit a correc�ve ac�on plan to be approved by the Govt.

Q21: Please confirm if a dig permit is required for any comm trenching and hyrdo-boring.

Q28: Atachment 2 shows a New Service Disconnect, will there be a separate service run to the building for the work desired?

A28: No. This is intended to be a service disconnect for the equipment. Per the SOW, contractor shall provide/install electrical panels, switches, and connec�ons needed to power control cab, distribu�on box, electrical starter unit, and fuel system as shown on the atachments.

Q29: Can a basis of design or any relevant informa�on from another engine test facility be provided? Also, use of silencers or other equipment in conjunc�on with the duct was men�oned in the site visit. May we ask for any informa�on on that as well?

A29: The solicita�on has been amended (amendment 3) to add pictures and drawings for similar roof vented systems. They will need to be adapted for wall vents, but this should provide a beter picture of what we are looking for. No silencers will be required in conjunc�on with the duct system.
