Division 28 31 76 includes Fire Alarm and Mass Notification and does not contain a specification on Security Systems. It is the only specification in Division 28.

AF A: Spec 28 10 05 – Electronic Security Systems (ESS)

On the drawings, there is a ‘CR’ on sheet T-134 in two locations, however they appear in multiple hardware groups while none were noted as existing at the site visit.

AF A: There is no sheet T134

Please confirm: Are upgraded door access cards required? If so please provide specifications, installation details, product data, and interface with other systems AF A: Designer needs to answer, could be that they missed this and did not include in specs

24. Please consider moving the bid date for Solicitation FA500419BA006 farther from Memorial Day. We are concerned about subcontractor coverage as so many people take more than a 3 day weekend for this holiday. We believe moving the bid date to the week of June 3rd will result in more competitive proposals A: Bid date has been moved to 26 June 19.

25. Do you have the 3D model the engineer and architect used to create these drawings available?

It would go a long way in making clear what is new and how it incorporates to the existing.

A: No

26. Has a Hazardous materials survey been conducted for this existing building?

A: Yes, See LBP Attachment

27. It appears that there will be significant upgrades to steel members. Are these existing steel members painted with Lead Paint?

28. Is there any known hazards in the existing dust in areas not routinely cleaned such as structural beams?

A: See LBP Survey and Response # 28 of other Q&A Sheet

29. Is there any asbestos containing materials anticipated to be disturbed by this project?

A: See LBP Survey and Response # 28 of other Q&A Sheet

30. Section A1/A-402 indicates a wall type 5 between the stairs and the Fan Room at the mezzanine level. Plan views of the stairs do not appear indicate any new walls at this location. Please clarify.

AF A: Need clarification from designer (Refer to answer provided to question 47 in previous question set.)

31. Please clarify wall type on office side of section A4/A-303. This section indicates wall type 3.

Enlarged Plan B1/A-401 indicates a type 2 wall.

AF A: Need clarification from designer (Refer to answer provided to question 12 in previous question set.)

32. Please confirm mezzanine walls between fan room and Bays terminate and connect at bottom of existing joist structure as shown on A1/A-302 and are not required to extend to roof deck. Stair at Vestibule 107 similar.

AF A: Confirmation needs to come from designer (Refer to answer provided to question 48 in previous question set.)

33. Please confirm if firestopping is to be applied both sides of the wall per detail C1/A-503. There may be inadequate access to effectively apply firestopping due to proximity of existing roof steel.

AF A: Complete work according to design

34. Please clarify 1 hour horizontal assembly indicated from grid A to A.6 + on sheet G-103. There is a one hour ceiling indicated above Hall 1148 but no other rated assembly locations in this area. Ceiling type 2 for rooms in this area is not a rated ceiling. Spray fireproofing is applied from A.6 + to west of B.3 only per A-123. Is additional type 1 ceiling required in this area or is this location not required to be rated ?

AF A: Needs to go back to designer to confirm which areas are to be rated and with what type of rating.

(Refer to answer provided to question 49 in previous question set.)

35. Will there be a walkthrough for the EIE-F35 Weapons Load Training project?

A: No, a site visit was conducted 10 May at 1400. No other site visits will be provided.

37. Sheet A106 seems to point us towards epoxy floor (EPX-1) for the hangar bays, the finish schedule on sheet A602 has clear concrete for the floor finish. Are we just place epoxy on the areas that we place new concrete in the hangar bays? Please clarify the extents of epoxy in the hangar bay AF A: There is a discrepancy in each drawing and designer needs to clarify what it needed and clarify EPX-1 means epoxy. Did not see in abbreviation legend on A001.

38. Please provide an anticipated NTP date so we can develop a schedule for the project to help with our pricing efforts. We need to understand what work will be taking place during what time of the year (for instance the roof) to determine if temporary heat and cover will be required.

A: See Question 33 from other Q&A Sheet

39. Section 01 11 00, item 1.1.2 Location. States, “The work is located at Building 1340, Eielson AFB, approximately as indicated. The exact location will be shown by the Contracting Officer.” There is no information in the documents that indicates exact location and/or access routes, or site laydown area and location. Please provide a civil drawing for these items.

A: See Vicinity Map and Haul Route document available on FBO.

40. Will Civil sheets be provided? There is a reference and line diagram to a new electrical service on sheet E111 and E211, without civil layout drawings there’s no way to understand the site conditions.

A: As builts were uploaded to FBO

41. Per section 02 61 13, Item 1.2 Description of Work, references “excavation and temporary storage of approximately 60 cubic yards of contaminated materials are shown on the drawings in the Appendices.” Where are these appendices? Where is the storage area to be located Please provide.

AF A: In the drawings (drawing set), if not, then error in omission

(Refer to answer provided to question 22 in previous question set.)

42. Has Hazardous material sampling of the existing structure been conducted?

A: See LBP Survey and Response # 28 of other Q&A Sheet

43. Per the solicitation, Page 10, 52.236-1 Performance of Work by the Contractor. 1984-04, States, “Performance of Work by the Contractor (Apr 1984) The Contractor shall perform on the site, and with its own organization, work equivalent to at least __ONE HUNDRED (100)__ [insert the appropriate number in words followed by numerals in parentheses] percent of the total amount of work to be performed under the contract. This percentage may be reduced by a supplemental agreement to this contract if, during performing the work, the Contractor requests a reduction and the Contracting Officer determines that the reduction would be to the advantage of the Government.”. Is this correct? Usually, there is only a 15% of self-performance requirement.

A: Has been updated to 15% with amendment 2 of this solicitation.

44. According to the SF1442 block 13.b the contractor is required to hold our offer for 217 calendar days for Government acceptance after the date offers are due. This assumes that the project would have a January 2020 start date which is in the middle of the winter. This would be an impactable time to start a project in that environment, with the earliest physical start date being late spring. Would the government consider a late spring NTP?

A: That date is to ensure full funding is received prior to project start. The building will remain heated through the winter, so work should be able to occur in the winter if its interior based construction

45. Will the sign-in sheet from the site visit be provided?

A: No

46. Will the contractor be provided with a laydown area for administration and material receiving, and storage? If so and where and what size?

A: Yes,

47. Section 01 14 00, item 1.2 Special Scheduling Requirements, Item (b) states, “The building heating and electrical systems will remain in operation during the entire construction period.” Does the government understand that due to the major structural upgrades, roof replacement, power service and systems upgrade this may prove to be impactable? What is expected of the contractor to achieve this?

A: Specific portions of construction that require power and heat to be out, will be coordinated through the base at that time. Primarily due to winter conditions the heat cannot be turned off throughout the entire project.

48. Section 01 14 00, item 1.2 Special Scheduling Requirements, Item (b) states, “The Contractor must conduct his operations so as to cause the least possible interference with normal operations of the activity.” Please define normal operations.

A: In the unlikely circumstance that any Air Force Operations have to occur in or near the construction site, the contractor needs to be able to work along side the govt. to allow for mission and work continuation.
