The following have been added by full text:

AMENDMENT 0004

Questions that may be of general interest to all Offerors and/or the Government and that are not readily answered by the proceeding changes will appear below. These questions may have been paraphrased or altered to represent several questions regarding the same subject and/or simply revised to clarify and simplify the question(s). Questions and answers are issued to the Offerors “for information only” and do not revise the solicitation, plans or specifications.

Question 1. Demolition plan states to demolish existing concrete pavement. Is any rebar or wire mesh in existing concrete pavement?

Answer 1. Available information on existing pavement does not indicate reinforcing in the pavement section.

Question 2. Detail A1 and A2 states to "Compact top 12" to 100% maximum dry density" This is practically unlikely. Will government allow compaction for top 12" above 95% maximum dry density?

Answer 2. Refer to Revised detail A1 and A2 on C-502 to state “Compact top 12” to 95% maximum dry density per ASTM-1557” as issued under previous amendment #3.

Question 3. Detail shows to "relocate existing conduit, equipment, and fixture as required for installation around new overhead door." Are these conduits required to be explosion proof?

Answer 3. The existing hangar bay is a Class I Div. 2 hazardous area and therefore seal off conduit fittings are required.

Question 4. Note on EP100 states to run conduit tight to structure along ceiling of existing hangar bay. Please provide height of roof steel in existing hangar.

Answer 4. The height of the roof steel in the existing hangar is 80’-8” AFF to the bottom of the structure.

Question 5. Section 08 11 13, on the door schedule it says to use hardware set 715 which isn't on there and I can't find it on any other plans. What should be done?

Answer 5. Door hardware is indicated with a “BT” prefix in the submitted door hardware group number 715.
