Answer: See construction drawings and Surge Suppression Device Notes for specific information.

Question 2: Note 2 on page E-204 indicates contractor to install new equipment described as single-phase in existing space at B90409. During the site visit, it was discovered that B90409 panel board is three-phase. Please advise on correct phase for B90409 and all other buildings receiving work.

Answer: Existing panel is 120/240V single phase.

Question 3: Is surge protection only specified for the main panels and not for communications or branch panels?

Answer: As shown on drawings, new surge suppression is only required for electric panels.

Question 4: For buildings with narrow driveways, 90413, 90416, 90419, and 90420, would it be permissible to drive a copper ground rod horizontal under the slab to prevent cutting and repairing the concrete?

Answer: Construct as shown on drawings.

Question 5: Once excavations are backfilled, are compaction tests required?

Answer: Compact in accordance with Sheet E-503 details. Test in accordance with industry standards and test reports are not required to be submitted.

Question 6: For 90407’s door bonding run, is connecting to the doors with mechanical connections permissible like the current installation? Typically, exothermic welding overhead, or above ground, is unsafe.

Answer: Door bonding must be in accordance with NFPA and AFI guidance. Bonding other than exothermic is allowed. Contractor can submit alternate methods during submittal process.

Question 7: Whether making exothermic or mechanical connections, the metal will have to be cleaned to base metal on all structures with metal, per NFPA 780-20 4.19.3. Are repainting surface areas required?

Answer: Surfaces must be restored to original condition to prevent corrosion.

Question 8: Per Test Well Detail on sheet E-503 the detail shows a compression connection to the ground rod. Should this be a mechanical connection (2 bolt LPS style) to allow for removal and reconnection during future testing?

Answer: Install per drawings.

Question 9: During the demolition of the integral LPS, are the components glued to the roof required to be removed or just the conductors and air terminals? Typically, once stuck with the M-1 or NP1 adhesives, these components do not want to come off. Prying off these components with priers could also pull the roof finish off.

Answer: Remove in accordance with General Note 6 on Sheet T-002. Do not remove adhesive bases as damage to roof may occur.

Question 10: Please confirm that proposals may be submitted electronically via the DoD SAFE Site.

Answer: Electronic submission via DoD SAFE site is one of three methods authorized. Please see Section L paragraph 2.1.1 for specific details to include requesting DoD SAFE drop.

Question 11: Drawing T-002 bullet 2 and specification section 01 14 00 paragraph 1.1 bullet D describes the contractor delivering a testing report on new lightning protection system to Hurlburt Electric Shop. It also states that the contractor may not begin construction on a new set of buildings until the Hurlburt Electric Shop has concluded testing. There is no defined timeline for the government testing to allow for advanced scheduling. This question is extremely critical to produce an accurate schedule for this solicitation. Please advise on the amount of time that Hurlburt Electric Shop will need to perform testing on each building.

Question 18: Specification section 01 57 19 Environmental Controls require the contractor to obtain a general permit for storm water discharge and create a Storm water Pollution Prevention Plan (SWPPP).

This project will only have incidental digging/ground disturbance and should be under the 1-acre requirement for notification. Will the contractor still be required to obtain the general permit for storm water discharge and create a SWPPP?

Answer: Disturbance under 1-acre does not require a general permit.

Question 19: Specification section 01 57 19 Temporary Environmental Controls item 3.5.1 states to notify the Air Program Manager 6 months in advance of bringing any equipment on the installation so that Clean Air permits can be obtained. This will not work in the allotted time provided for completion of this work. Will the government require this to be completed?

Answer: Notification is only required for stationary power or fuel tanks. These should not be required for this project.

Question 20: The demolition drawings have the contractor removing wooden poles and setting new ones. There is no reference to an engineered lift plan in the drawings or specifications. Is it the intent of the government to have the contractor provide an engineered lift plan?

Answer: A lift plan is not a required government submittal.

Question 21: Drawing E-203 calls for directional bore of conduit under existing asphalt for installation of new secondary feeder. The specific conduit stated in the singe line diagram states a #4 – 1 1/2” rigid galv. steel conduit that is plastic coated. This conduit seems to call out for a plasti-bond conduit, which cannot be directionally drilled. Please advise if there is an alternate conduit for use on drawing E-203.
