Per the Design Guide the only fire panel manufactures acceptable on WAFB are Siemens, Simplex or Notifier. Are we to use the manufactures listed in the project specifications or are we to use those listed in the Whiteman AFB Design Guide?

It appears that if we are to use both resources, the only manufacturer that we could use would be Notifier as it is listed in both publications.

ANSWER: The manufacturers shall be in accordance with “Whiteman Fire Emergency

Services Design Guide” dated 4 May 2017, Amendment 0003 attachement. Section 281111, Building Fire Alarm system and Mass Notification System, Para 2.1 shall be changed as follows:

44. QUESTION: How many cables will be in each faceplate? 2, 3 or 4?

ANSWER: Four (4)

45. QUESTION: Does the Government intend on issuing any Division 1 specifications prior to the bid? Division 1 specifications are critical to the preparation of a project schedule. Normally, Division 1 provides information regarding preconstruction activities and meetings, the construction document / materials submission process and government review/approval durations, and project close out and acceptance procedures required by the CO for final acceptance. All of these activities take time and are critical to establish the necessary task durations in order to achieve the contract completion date prescribed by the contract proposal.

ANSWER:

46. QUESTION: Please confirm that the Government will retain the services of the project

Commissioning Agent, (CxA) as stated in specification section 230800.

48. QUESTION: What permits and fees are applicable to this project?

ANSWER: There are no additional fees required for any permits. The only permits required are local permit for “Excavation.”

49. QUESTION: We have found 2 ½” Type K waterline and fittings to be difficult if not impossible to obtain what alternatives will the Government accept?

ANSWER:

Recommend staying with 2 ½ Type K. May be modified during construction if not available.

50. QUESTION: What is the deadline to submit additional RFI’s?

ANSWER: Deadline for additional questions will be provided in Amendment 4.

51. QUESTION: Due to the small scale of this project, will an AISC certified fabricator and erector be required per the specs (051200-1.6)?

ANSWER:

Most reasonable size shops are AISC and this does help establish a qualified contractor.

52. Please issue any available as-built drawings to better aid us in our proposal, especially related to

MEP items.

ANSWER:

53. After reviewing the Phasing plan, it appears swapping Phase 1 and Phase 2 will provide a better work flow, especially for the Mechanical items. Will the swapping of these phases be acceptable?

ANSWER:

Contractor to set up detailed phasing plan.

Original concept was to have Smitty move once and that is how Phase 1 was decided.

Temporary heating and cooling was discussed. Option for contractor to provide switchover between phases during tenant move also discuss.

Swapping Phase 1 and 2 per the question above would be less problematic since Phase 1 areas

(Current Shop and Storage) are conditioned with Roof Top Units. Smitty would move to the existing Shop and Storage prior to start of construction. After the Phase 2 areas (built as the 1st

Phase) are complete, Smitty would move into the Classroom areas. Smitty would need to move once more after completion of Phase 1 (Built as Phase 2).

LACK OF EXTERIOR REPAIR:

The original budget during design for this projects was about 2.1 million and we were minimize design scope creep that would increase the budget. Replacement of the aluminum entrance, new roof and an exterior facelift were not included in our scope of work. Exterior work was limited to only what was necessary to accommodate the interior remodeled spaces.

The primary public faces of 527 (North and West) are basically brick and prefinished metal storefront and fascia. The East and south faces at the service drive is where most of the older components needing repainting are located. Sheet A-201 General Finish Notes and the notes on the elevations call out what is to be painted and its need for preparation.
