BID QUESTIONS:

Project Name: Arapahoe Community College Project #: 2015.016

Walkway Renovation Date: September 8, 2015

RESPONSE:

1. On Sheet M2.1, “Ground Floor HVAC Plan at the left hand end, there is a rectangle drawn on the plan next to the RG-1. What does the rectangle represent?

That was a drafting error, please disregard.

2. Is Kawneer the only supplier that is approved for the metal and glazing system on this project?

Kawneer is the only approved manufacture for the storefront system.

3. Confirm that drawing sheet G1.2 is not included in the plan set.

G1.2 was inadvertently left out of the Bid Set, see attached.

4. Hardie Reveal Panel System: Specify the wind load design for steel, i.e. ‘Z’ girt spacing.

See S1 for design wind loads.

5. Specify material ‘1/2” exterior sheathing’ in various details sheets A5.1 & A5.2.

The exterior sheathing needs to be an exterior gypsum board product in order to meet the UL requirements.

6. I don’t see a spec for the wall base and the plans say “match existing.” It appears to be a black 4” vinyl cove base. Do you have a particular manufacturer, style, or color that is campus standard that we need to use?

4’’ ROPPE rubber-black.

7. Are there any Temperature Control specifications, or sequences of operation?

This fan coil unit shall be independent of the buildings temperature controls system. Standalone control. The sequence shall be:

1. Local wall mounted temperature sensor shall automatically start the supply fan in the FCU and modulate the normally closed two-way control valve (either heating or chilled water coil control valve) to maintain space temperature set point.

8. Do you know who the fire alarm company for the building is?

9. How firm is your dates to be substantially complete by November 30, 2015 and final completion December

31, 2015? For it usually takes one month to get a contract fully executed by the State so the potential start date would be October 14, 2015, which would leave 45 calendar days for the project, and not accounting for holidays during this period.

10. Partition Types on A1.1 indicate 5/8” exterior sheathing. The details on A5.1 indicate ½” exterior sheathing. Please verify the thickness of the exterior sheathing. Also please verify the material for the exterior sheathing.

Walls should be built per details and UL requirements.

11. Section 4 on S1 indicates 1” 26 gage Type E metal deck for the roof. Sections B and C on A3.1 indicate ½” sheathing as well as detail E on A5.1. Please clarify the roof substrate material.

Metal deck is required per the structural drawings.

12. The detail for the column that is beyond the glazing shown in L A5.1 shows outside corner trim for the hardie panel system. The columns between the storefronts shown in B on A5.2 do not indicate outside corner trim but the detail N on A5.1 for the lower portion of the column between storefronts does show corner trim. Please verify this is the intent.

The intent is to have the full Hardie board system including the trim pieces.

13. Detail C on A5.2 has a note for prefinished metal flashing, but I can’t quite figure out the intent. Should the

Hardie system have J mold at this location?

This flashing is designed to separate the window system from the rain screen, sealing the window off from any moisture penetration. The Hardie J-trim would allow moisture behind the rain screen and into the window system.

14. Please clarify if Hardie soffit is to be place on the underside of the columns shown in detail N and O on A5.1.

Yes there will be a 3 ½” wide strip of Hardie board on the underside of the pilaster overhang.

15. It the hardie system to have J mold where it abuts to existing construction?

Yes

16. Structural S1 shows the smaller walls as 4”. The partition schedule on A1.1 calls them out as 3 5/8” please clarify.

These will need to be 4” studs per structural drawings and details.

17. Section 4 on S1 shows a diagonal kicker. Section B on A3.1 does not show this. Can the drywall be placed on the angled stud kickers or will it need to be cut in around it.

Yes, as part of the structural system the kickers will need to be part of the UL system.

18. All the details on A5.1 and A5.2 show multiple layers of drywall but the partition schedule on A1.1 calls only for 5/8 gyp. Please clarify.

All construction will need to meet the proper UL rating and listing, with multiple layers on gypsum board per the details.

19. The gypsum board spec section requires using USG brand primer, while the Interior Painting spec section requires Diamond Vogel brand primer. Please advise.

Diamond Vogel is to be used.

20. Please indicate where section 6 on sheet S1 is cut.

Typo this is section 5 on the plan

21. The specs indicate 5/8” Glass mat gypsum substrate board at the roof, while the drawings state ½” exterior sheathing. Please advise.

½” exterior gypsum sheathing is acceptable to meet the required UL rating.

22. The section cuts in the A-sheets do not show the metal deck above the roof joists. Please verify that there is metal deck above the roof joists.

See question #11.

23. The parapet cap is to match existing, but there is no visible parapet cap near the work site. What is the existing color that we are to match?

The top of the adjoining Annex build has a parapet cap, use this to match.
