Roofing

Drawing A-191, detail 3 shows a new slate tile roofing to match the existing, however no information about slate tile is given in the specifications. This appears to conflict with Drawing A-442 which calls for “Slate Look fiberglass roof shingles (match existing Ecostar empire Slate, Solor to match existing, or approved equal.)” Please confirm we should follow direction provided on A442, and not provide natural slate, or provide alternate direction.

Follow direction on A-442 for the roofing material on the elevator tower. This note includes the product information from the client on the slate-look fiberglass shingles that are currently being installed on an adjacent building. - SMDK

Metals

Several notes in the drawings still state that the contractor shall remove exterior handrails for stockpile and reuse; for example, see note 2/AD-130 for example. Please confirm that all railings and railing components will be moved by others prior to the start of this project and we should price furnish and installation of all new railings (see note 2/A205 for example).

The Contractor will be required to remove the existing railings that remain, and add them to the stockpile of railings that have been previously removed under the on-going project (Phase I). Based on the amount and quality of the handrail pile, the Contractor and the Contracting Officer will collaborate on a path-forward for use of the rails. For the proposal, the Contractor shall price the procurement and installation of all new rails. See Spec section 01 05 00, paragraph 1.4.

General

RFP Section 5.1, FACTOR 1 states relevant projects must “demonstrate…completion…within six years of the original date of issuance of this RFP.”

Is it permissible to submit a project currently under construction as long as it is more than 75% complete?

No. The project must be "physically and successfully" complete (100%) within six years of the original date of the issuance of the

RFP. (TML)

Specification 087100 part 2.5 Finishes calls for stainless steel hinges for exterior doors.

Unfortunately all hardware sets have ANSI BB8111 listed. This is for steel based ferrous hinge. It is our understanding that the model number takes precedence. If stainless steel hinges are required, model number should be changed to BB5111 where required. Please clarify with a list of doors where stainless steel hinges are required.

All new exterior doors should have stainless steel hinges per 2.5 Finishes. This effects all exterior door sets including HW-51, HW-1A, HW-16, HW-16A, HW-51A, and Hardware sets at the Condenser yard, Generator Enclosure, and Doghouse Door at Fire Pump Room as shown in Amendment #1. Per 3.6 Hardware Sets (second paragraph) "The door hardware sets listed below are provided to establish a general intent to develop the final submittal for review." Per this statement, please consider the model numbers within the hardware sets as a guide only and take the requirements for individual components in Part 2 of the specification as requirements.

52, HW-53, HW-53A, HW-56 and HW-56A have no means of stop listed. Please provide missing information.

Door Closers are required for all Fire Rated doors to meet code. Blast-resistant doors need them as well. Please add closers to the following sets: HW-1, HW-16, HW-16A, HW-16B, HW-26A, HW-26B, HW-

27, HW-27A, HW-38, HW-51, HW-51A, HW-52, HW-53, HW-53A,

HW-56, HW-56A.

Add Floor stops for all remaining non-fire rated hardware sets listed, unless closer is needed to provide a complete tested sound assembly on STC rated doors (provide closer if needed for STC tested assembly): HW-1A, HW-26C

Doors

Every lockset/latchset is bored except one in Set HW-15 that has ANSI 36 which is for preassembled (passage) latchset. This appears to be a possible error. Please confirm this is correct or provide additional information.

Also set has electric strike. Why? You can just open the door since it is passage function. Please confirm electric strike is required.

Per responses above included in this RFI, HW-15 is no longer in use on any doors in this project. Please delete set.

Doors

Sets HW-15, HW-31, HW-31A, HW-31B and HW-40A have automatic flush bolts but no dust proof strike which we believe is required by code. Should dust proof strike be added?

Add dust proof strike if required by code. Per spec section 3.6 Hardware Sets (second paragraph) "The door hardware sets listed below are provided to establish a general intent to develop the final submittal for review." The sets shown are a guideline. Please submit hardware sets for Designer to review that meet required codes and intent for the door operation.

Set HW-40 has no means of securing inactive leaf. Is this the intent? If no, please provide additional info.

Add 1 PR of automatic flush bolts to HW-40.

Doors

Set HW-40A has automatic flush bolts but no means of closing both leaves. Is this the intent? If no, please provide additional info.

Add 2 closers to set HW-40A. Closers are required for the fire rating and will provide closing for both leaves.

Doors

Set HW-56 and HW-56A are for fire rated doors but have closer with hold open arm.

Labeled doors cannot be held open by code.

Please clarify.

Hold-open feature on closers can be eliminated in sets the contractor sends in to the designer for review for these doors.

Doors

Set HW-30 has kick plates but no closers.

Kick plates are normally used when door have closers. This appears to be a potential error. Please clarify. Also the Cipher model number listed in 087100 part 2.3.16 requires a cylinder but no cylinder is listed. Please provide missing information.

Closers should be added to this set. Per previous responses, this is a fire rated door set and closers are required per code.

Doors

Sets HW-31, HW-31A and HW-31B are pair of doors but only one means of stop is listed.

Please provide second means of stops.

Provide 2 floor stops foreach of these double-door sets instead of the currently-shown 1 floor stop at each set.

Doors

Door 001A has door type G (Non-blast) but has Blast listed in door schedule notes.

Should blast be deleted in notes or should blast be added to door type G like door type C and D?

Door type for 001A should be revised to "E", which should be a "DBL

UNEVEN BLAST".

Frame type 4 does not provide transom height just “see sch.”. Please provide transom height.

Transom height shall be field verified as we are placing the blast doors into existing openings.

Doors

Hollow metal spec only lists Level 1 for frames. Interior doors are 18ga and exterior doors are 14ga, but all frames are 18ga?

Please confirm. Also spec lists both KD frames and welded frames. May knock down frames be used at all HM doors?

Exterior door frames are all blast-resistant assemblies that should be built to withstand the blast pressures for the project. See Blast-resistant Doors spec. At a minimum, exterior doors and frames should both be 14 ga, welded frames - but the tested blast assembly requirements shall be met for each of them.

Doors

029B is a cased opening (no door) but is STC50 and 90 min. Should STC & fire ratings be deleted or door added? If door requested to be added, please provide hardware and other missing information.

Cased opening 029B will not have STC or Fire ratings. Ratings should be removed from door schedule for this door.
