Q1. In the sow it says they are no bid options, but bid option 1 is listed on numerous pages, but a bid option is not listed on page 3 of 53 in solicitation. Please advise.

A1. Per Statement of Work dated 21 April 2016 paragraph 2(a): There are no bid options associated with this construction project; any references to bid options in the specifications or drawings shall be included in the single base CLIN that will be awarded on this contract (information to be updated in Amendment 0001 to state that any references to bid options shall be included on CLIN 0001 of this contract since CLIN 0002 for fire suppression system was created after SOW).

Q2. I see the specification section for long term base access, but no specific needs for the site visit at 52.236-27. Do I need to only gather the affidavits for base access or are there other requirements for you?

A2. The forms that are required are the affidavit (Attachment K of the solicitation) and the memorandum template (Attachment L of the solicitation). This can be found in section 2.9 of the Section L

Q3. On page A-201, note 11 it shows new led fixtures above the doors, but on the electrical drawings E-5,6 it does not reference any fixtures, nor is it listed in the fixture schedule on page E-6. Please advise.

A3. Approved drawings indicate light fixtures types D & E at exits. These are included on the fixture schedule on page E-6. Please refer to the approved drawings. No fixtures are to be installed at the exterior doors.

Q4. Also on page E-6 top right it references fixture L and M, but these are not in the schedule or on the prints. Please advise.

A4. References to fixtures L and M are incorrect. The correct type of fixtures are Fixtures H and J, respectively and have been corrected on Drawing 14AK Addendum #2.

Q5. Also on page E-6 on the fixture schedule it shows a triangle with no letter? But on page E-5 room 111 it shows 5 of these symbols?

A5. The approved drawings clearing indicate the items. Please refer to approved drawings.

Q6. On page E-5 top left note 4 it calls for dimming ballast in fixtures A,B,F, and G, but nowhere on the prints are there any dimmers shown?

A6. No dimming is to be installed. Delete any reference to dimming ballasts in fixture details per Drawing 14AK Addendum #2.

Q7. On page E-17 panel schedule H2N and H2S it does not show the aic ratings of the panels?

A8. Janitor Rooms 118 and 224 will be fixture type C unless noted otherwise. See Drawing 14AK Addendum #2.

Q9. On page FP-2, re: notes 5,6,11 it shows 2 sizes of hand holes 1 for communications and 1 for electric as shown on details on page FP-9. I only see 1-4” pvc conduit but two different types of work, communications and electrical. Typically you don’t put these two different types of work in same handhole. Are there supposed to be 2 conduits? One for electrical and one for communications. Please clarify. Also the prints read that this work is to be in base bid? Is this correct?

A9. There is only one (1) 4" conduit and a water pipe from Building 421 to the fire pump building. This conduit is for a future fiber optic cable that will communicate between the two facilities. There is no electrical work in this handhole/conduit system. Both types of handholes are for the future fiber optic cable. The traffic rated handhole is for installation in graded areas and the aircraft rated handhole is for installation in the aircraft parking apron. Ignore all references to base bid or options per Statement of Work paragraph 2(a). All work is to be done at one time.

Q10. General—Will the equipment presently contained in the hangar bay remain or will the entire bay be left open when we receive?

Q11. General—Will a fence be required along the West end of the hangar to retain materials and personnel from being in an area that they should not. If so, what height and material should be used—Chain link with slats or polyethylene barrier, etc.

A11. Spec. Sec. 01 14 00 para. 1.2.4 requires the contractor to provide temporary closures as required to maintain security and protect non-work areas. The type and layout of fencing or temporary construction to separate work areas from non-work areas is at the discretion of the Contractor, but may be submitted with the health and safety plan submittals, or as directed by the Government.

Q12. Sheets AD-01, A-103, A -401—The existing floor slab is to be removed (demo note 13) in preparation for the new baths. Since this is an existing hangar, is there anyway the thickness of the slab to be removed may be obtained; it could range from 4” to 1”.

A12. Existing as-builts indicate floor slabs to be 6” with or w/o W.W.M., and some footings 12” to 24” with continuous #5 bars. However, the contractor is responsible should existing conditions differ from this information.

Q13. Solicitation FA2823-16-R-4028, page 42, paragraph 2.2.1----A construction progress schedule can be provided as stated with the exception of being able to express percentages with each item.

A37. Use synthetic stucco finish coat on cementitious stucco on metal lath on air barrier on gypsum sheathing on metal studs, per detail 4/A310.The detail should include "synthetic stucco finish coat", and should not include the "zees".

Q38. The aluminum drip flashing (Key Note 18) is shown to be installed on top of the air/vapor barrier (Key Note 24). It appears with this sequence of installation any moisture could wick between the flashing and air/vapor barrier. We typically see the flashing installed first and the air/vapor barrier would be applied over that. Please review and clarify.

A38. Section 4/A310, : the drip flashing is to be installed after fluid applied air/moisture barrier.

Q39. The demolition notes on sheet FP-2 – Notes 1 and 2 indicate that the existing concrete pavement is to be removed in 10 lf x 10 lf sections and then replaced after the installation of the underground water lines and pvc conduit. Sheet C-501 calls out a concrete pavement detail and notes to utilize 4000 psi concrete. Below this detail is a typical pavement section calling out 12” concrete with a minimum 4000 psi FLEXURAL strength.

Questions:

a) The typical pavement section indicates a 5’0” wide section, yet we are replacing a 10’ wide section of concrete pavement according to the notes on sheet FP-2. Please clarify if the 5 foot dimension should read 10 feet.

b) The typical pavement section indicates an 18” diameter rebar cage with number 3 rebar and a #4 rebar running through it. Where is the rebar to be utilized?

c) Is the concrete strength to be 4000 psi Compressive strength or 4000 psi Flexural strength

A39.

a) Since it's a typical pavement section, the dimension should read "as noted on plans." Refer to revised details in drawing below.

b) The 18" diameter rebar cage with #3 and #4 bars is not required in a typical concrete pavement section. Ok to delete. Refer to revised details in drawing below:

c) Compressive strength is 4000 psi; flexural strength read be 500 psi. Refer to revised details above.

Q40. Reference Section 4/A310 – At the head and sill of the stucco infill a 10 Ga, ¼” continuous plate (Keynote 25) is called out and says to “see structural”. Detail 3/S8 is the structural detail for the LTGA Existing Opening Infill. The structural detail does not indicate the ¼” plate called for in 4/A310. We need to know how to attach the plate (fastener types and sizes as well as spacings). Is the plate steel galvanized or plain steel with primer?

A40. The structural drawings were revised during the design phase and the change did not get picked up on the architectural drawings. The plate, as called out on Note 25 on A310, was eliminated and the studs are to be attached with the clips, as shown on section 3/S-8. This occurs at the masonry infill detail only. The plate is still required at all the openings receiving a new window; however, the plate is 10 gage (per section 2/S-7) and not 1/4" (per note 13 on sheet A-610). The attachment for the plate (fastener types and spacing) is called out on section 2/S-7. The 10 gage plate at the window openings shall be painted, and not required to be galvanized.

Q41. Regarding the past performance questionnaires for the subject solicitation: Will previously completed past performance questionnaires-for separate solicitations-be accepted? The questionnaires are recent.

A.41. No, the past performance questionnaire provided in the solicitation must be used, or a completed CCASS/CPARS evaluation.
