FXSB182423 Repair Tactics/Intel/Mission Planning, H18 Questions and Answers

22 August 2018

Q1: Will you allow another site visit?

A1: Yes, please see amendment.

Q2: Please confirm that new carpet will be installed throughout the area.

A2: Yes, new carpet throughout the project area.

Q3: The (2) existing doors into the area appeared not to have any STC rating labels that show testing in accordance with ASTM E90/99, along with no gaskets on the outside of the door and Auto Door Bottoms. Please verify if these doors will need to be considered for replacement.

A3: Per IC Tech Spec for ICD/ICS 705, paragraph 9.D.1, the finished perimeter must meet “sound group 3 or better standards”. Furthermore, doors must meet the standards of section 3.E of the tech spec. The existing doors may be re-used if they will meet these standards.

Q4: Can AS BUILTS be provided for architectural/electrical/mechanical/fire suppression?

A4: As-builts cannot be shared electronically until the contract is awarded; however, contractors may come in to view as-builts at 7252 Gibson Ave, JBER prior to submitting bids.

Coordinate time with Capt Daniel Koch (552-0086) or Mr. Jerry Romig (552-4884) to view them.

Q5: Will the (2) existing doors need to have the X‐09 upgraded to X‐10?

A5: See answer to Q3. Doors and hardware must meet the tech spec. Contractors should determine what upgrades and/or modifications are required to meet this standard.

Q6: Can it be determined on the existing perimeter walls what STC level these are in case the

(2) doors will need replaced with an STC rated assembly? Also to determine if one layer of 5/8” GWB is on the uncontrolled side and two layers on controlled side for Sound Class 3.

A6: We are unable to find an STC rating specified in the as-builts or on the doors.

However, they are 1-3/4” solid core wood doors.

Q7: The electrical outlets and comm. outlets on the perimeter walls seemed to have a mix of surface mount and flush mount. Is it desired to have all the boxes flush mount to keep a uniformed STC level across entire perimeter or will demo be needed around all flush mount boxes to add extra sound attenuation material?

A7: All conduit and outlets, for both power and comm, shall be surface mounted so tampering can be easily detected.

Q8: A mention of acoustical paneling to be installed on perimeter walls surfaces during the site visit. Please confirm if this will need to be considered or if additional layers of GWB will be needed.

A8: Acoustical paneling shall be installed along the controlled side of the north, west, and south perimeter walls of the work area. The Contractor is required to determine the type of paneling; however, Soundsoak Acoustical Wall Systems was used in a previous contract at another base. The Government is not stating this type is to be used – this is just an example.

Panel selection will be required to be approved through the submittal process.

Q9: Will exposed electrical conduit or wire mould be desired? If exposed will the conduit and boxes need to be painted?

A9: Yes, all power and comm conduit/wire mould will be exposed surface mounted. They shall be painted to match walls.

Q10: Please clarify how many power drops will be needed.

A10: Existing power drops on the remaining walls are adequate. Per the as-builts, that is 49 drops (should be field-verified). Power and comm from walls to be demolished should be coiled, labelled, and left above ceiling for future use.

Q11: Is a freight elevator able to be accessed to get materials to the 3rd floor?

A11: There is not a freight elevator in this building, only the elevator located at the front of the building.

Q12: Please confirm that new wall will terminate at new hard lid ceiling?

A12: Yes, new wall may terminate at hard lid ceiling or higher. Where the wall already continues above where the hard lid will be, the existing wall may remain above the ceiling (i.e. it does not need to be demolished).

Q13: VERSION 1.4 IC Tech Spec – for ICD/ICS 705 Chapter 3.D.1. “Floors and ceilings shall be constructed to meet the same standards for force protection and acoustic protection as walls.” Please confirm that no additional GWB/plywood/ expanded metal or mesh will be needed on the top of the ceiling framing for the controlled side perimeter walls?

A13: No, the perimeter walls currently extend to the building pan-deck, so no additional material is needed on top of those walls.

Q14: Please confirm if contractor will need to supply sound testing/reporting?

A14: No, sound testing will be performed by the government.

Q15: Will new wall layout be confirmed in an amendment?

A15: Yes, see updated attachment with final wall layout. Only change is removal of one interior door.
