Q27. The area bound by BL - C to D and 2.3 to 3. The exterior deck in this area needs to be removed for the new footing? What is to happen to the deck that is indicated to remain since it will be affected by the installation of the new footing in this area? Also, what happens to the existing exterior soffit in this area?

A27: See AD101 for demolition notes. See A101 and A201 for plans and elevations of the completed areas, showing (for example) extents of deck re-installation.

Q28. Drawing AD101 – note 12 indicates demolish all ceilings on first floor… and room 109 has a coffered ceiling. Is this ceiling structure to be also removed?

A28: Ceiling structure is not to be removed U.O.N. In addition, Note #12 is revised to indicate ceiling in Room 109 is to remain per Drawing A105 and A106 indications of ceiling changes. See “Changes to Drawings” above.

Q29. Drawing A201 east elevation, BL 1.1 to 2, indicates a new window 04. The demo and rebuild floor plans do not indicate anything at this location. Please clarify.

Q35. S001, Deferred Submittals, #1; S102, HRV-1 Support: In drawing S001 it shows that the contractor is supposed to get engineering for all seismic anchorage of equipment for electrical and mechanical. On drawing S102 it calls out for the structural support for the HRV unit. Does this mean that the contractor is only to get design on items already not specifically called out in the drawings?

A35: Contractor must verify design on S102 is compatible and appropriate if HRV-1 does not match the Basis of Design HRV-1 unit described on Sheet M002, or if Contractor changes mounting provisions in any other way. Otherwise, anchorage may be performed via the seismic support shown on S102. For all other seismic anchorage contractor is responsible for engineered seismic drawings/design.

Q36. Opening 203 is not assigned to any hardware group. Please advise.

A36: Door 203 is intended to be in Hardware Set #12, all items reused except for Wall Stop. See Changes to Specifications, above.

Q38. Are the existing locks being reused a) cylindrical or b) mortise? This will affect preps on new doors and frames?

A38: Existing locks being reused are mortise. Contractor is to verify existing conditions per Specification 08 71 00 – Door Hardware, Paragraph 1.3.B Coordination, Existing Openings, for further information.

Q39. Spec 01 50 00, 2.3, B: This spec says that the contractor is only able to use the HVAC for heating if approved by owner. If not approved we will would have to heat with an external heater. This could cause cost to be much higher. Please specify if the current heating system in the building will be available to contractor for heating of the space?

A39: The current (existing) system is permitted to be used for duration of construction. The intent of this Specification section is to limit and/or prohibit use of the NEW HVAC equipment during construction. See Changes to Specifications, above for revised Specification 01 50 00.

Q40. AD102. At the entrance to the second floor from the stairs located by Grid Line –A there is a window overlooking the entry prior to the corner which has three windows currently. There is also one on the other side reciprocating the first window. Are these two windows supposed to be demoed or do they remain like the other three? Please advise?

A40: This question is best handled as an RFI after contract award. Assume windows are to remain, for bidding purposes.

Q41. On AD101 & AD102 I see 20each “TYPE A” windows. Demo sheet note “A” says to bid option one to replace with new. Are these the Fiberglass windows? And what are the sizes and configurations because there is no schedule and I see multiple configurations on the two demo sheets. There are some windows with 1 section, some with 2 sections and some with 3 sections. Please clarify?

A41: Bid option replacement windows utilize the Fiberglass windows; see A302 for example call out. Sizes to be field verified by Contractor.

Q42. Regarding the reused wood windows, I see 4ea on A201 that are being replaced and 1ea on A202 that are being replaced. Are all the other windows being reused?

A42: Windows remain unless otherwise noted.

Q43. Regarding access hatches. The schedule on A106 calls out 20” x 24” and the description in Stair 100 calls out 22” x 36”. Please clarify?

A43: Remove 20”x24” description from the Legend such that the symbol identifies an access hatch (but does not identify a specific dimension). See Changes to Drawings, above.
