Drawing S-102 calls for Pre-Engineers Bldg (PEMB) by others. Please advise if this in GC's Scope of Work.

See drawing S-002 for Metal Building System notes. Also see section 13 34 19 – Metal Building Systems in the specifications, paragraphs

1.2.11 Engineering, 1.4 System Description, and 1.5 Submittals.

We are missing the Drawing E-401 from the above mentioned project.

This drawing is listed in the Title page.

E-401 was part of drawings for previous design dated July 17, 2015.

Drawing was an enlarged plan of the Electrical Room. Drawing E-401 was omitted from the set of drawings dated Feb. 2, 2018, and should have been removed from Title page. See E-201 for layout of the Electrical Room.

The plans do not delineate what percentages of the site work to be divided up in Items 1 & 2 of bid sheet breakdown. Please advise.

See drawing C-101 – Site Demolition Plan, shows area asphalt or concrete being removed for new construction and utility tie-ins, and demolition of building 3326.

The overhead vehicle tailpipe exhaust removal system found in Section 23 35 00.00 10 - Overhead Vehicle Tailpipe Exhaust Removal System(s) of the written specs and Drawings M-101 and M-602 regarding the overhead hose reels. It notes in the hose reel schedule that we must provide high temperature hose. I can't locate anywhere what the continuous temperature you are looking for throughout the hose from the exhaust, so I can quote the correct high temperature hose.

Note below Hose Reel Schedule on drawing M-602 states: Provide with High Temperature hose and vehicle adaptors. See attachment for cut sheets provided by the A/E for hose reels, by Car-Mon Products.

Cut sheet shows hose type HTC is listed as only High Temperature hose with heat resistance of 1000⁰ F.

Reference is made to the experience matrix within specification section 01 45 00.00 10. To retain and have on the GC staff multiple engineers as specified within this matrix will place a large administrative cost on what is a relatively simple project.

Would a QCM with CQC certification be sufficient especially since the mechanical and electrical systems require commissioning?

Perhaps adding the following should suffice:

a) Civil QC could be managed with soil density & concrete testing

b) Mechanical & Electrical l QC managed through on-site verification

& commissioning

c) Structural QC managed by Structural inspections by a structural engineer at material delivery, twice during erection and a final at completion of the building, rather than full time.

See specification section 01 45 00.00 10 Quality Control, paragraph

3.4.2 CQC System Manager, states: The CQC System Manager must be assigned no other duties. Identify in the plan an alternate to serve in the event of the CQC System Manager's absence. The requirements for the alternate are the same as the CQC System Manager.

Paragraph 3.4.3 CQC Personnel and Fulltime Mechanical/Engineer QC, states: These individuals must be directly employed by the prime Contractor and may not be employed by a supplier or subcontractor on this project; be responsible to the CQC System Manager; be physically present at the construction site during work on their areas of responsibility.

Refer to the Experience Matrix on page 5 of this section.

AD-101 shows no removal of concrete floors. In the structural drawings Sheet S-101 shows new 4" Slab in rooms 105 & 112, between Column Lines 8 & 8.5. Please advise.

Please confirm the required window types and locations. Plan sheet A101 does not coincide with elevations located on sheets A-201 and A202. When following the elevations per A-201 and A-202 window types located on A-604 do not include window types 3 and 5. Please confirm if these window type are utilized and where.

Window schedule on drawing A-604, and floor plan on A-101 are correct. Elevation drawings A-201 and A-202 windows labeled as W2 should be labeled as W3 type windows. Window closest to door with awning, labeled as W1, on north elevation, should be labeled as type W2 window.

Drawing A101 references a cross section on sheet A-302. Sheet A-302 is not included in the documents. Please provide sheet A-302 for reference.

Cross section reference on drawing A-101, should have been changed.

Section detail located on drawing A-202, detail 2.

Drawing A502 Wall types #18 and #19 appear to be labeled wrong on the plans. (Wall type 18 should be wall type 19 and wall type 19 should be 18.) Please confirm the required wall types at the perimeter walls of the new PEB. Additionally, wall type 19 shows a stud wall within the PEB but does not provide a desired height for the required stud and sheetrock. Please confirm the desired height for this wall type.

Correct, wall types #18 and #19 are miss labeled on drawing A-101.

Wall type #18 should be for the office area and restroom exterior wall.

Metal stud and sheetrock to be 10’ above finished floor for wall type #18, or 6” above drop ceiling height noted on drawing I-601.

Wall type #19 should be for the new General Service Bay and New Refueler Bay exterior walls. Metal stud and sheetrock to be 8’ above finished floor, as noted in wall type detail #19.

The drawing set references a detail #8 on drawing A-512. This detail is not included on sheet A-512 for the soffit detail as called out within the wall sections on A-321. Please provide detail #8.

Section 4 on drawing a-321, calls for soffit detail 8 on drawing A-512.

Correct detail located as detail 3 on drawing A-512.

Note all other references for detail 8 is for soffit detail for Prefabricated Metal Building, which was not provided.
