692-22-105 Renovate space in Buildings 217A and 218A for Mental Health Q&A

1. Use of Previously Submitted PPQs:

· Can we use PPQs that we have submitted for other bids, provided they are in the same format and dated within the last year?

· Will using these previously submitted PPQs deem us non-responsive?

You can use previous PPQs as long as they are relevant and within the past five years Hydronic System Water Treatment

2. Missing Specification Section:

· Spec section 23 21 13-19, 20 refers to section 23 25 00 for water treatment procedures and products, but section 23 25 00 does not exist. Can clarification be provided or an RFI issued for this missing section?

Section 23 25 00 has been attached/provided Scope of Work on Frames, Doors, and Hardware

3. STC Rated Doors:

· The required STC 55 sound rated doors are specified to be 3" thick (A/E has not specified 3” door panels), but the current specs list a 1-3/4" door thickness. Can this discrepancy be addressed?

There are numerous products/systems that utilize 1 ¾” door panels that meet or exceed the STC 55 rating. (i.e. Assa Abloy, CECO, etc…) Doors to align to specification documents provided.

· Will the STC door manufacturer supply the frame, door, hinges, and gasketing?

Not necessarily – Depends on how contractor procures and organizes the components.

· Will the locksets specified require a special backset and modifications due to the door thickness and gasket requirements?

N/A, the doors will not be 3”

· Are doors constructed with metal and wood veneer applied acceptable?

Yes

· Will there be a requirement for thresholds and automatic door bottoms if the manufacturer performs the door undercut?

The hardware will be required as specified. Once the door manufacturer is engaged and if they recommend an alternative in lieu Auto door bottoms / Thresholds the A/E would consider a change at that time. As of now, thresholds and automatic door bottoms are to be included as specified.

· What is the current lead time for STC 55 doors after approvals?

A/E cannot answer this inquiry. This depends on manufacturers utilized, the market, supply/demand and time of construction.

We just heard (a current project being constructed) had a 20-week lead time for standard fire rated doors and frames.

4. Shingle Specifications:

· AE102 - Notes #2, 3, and 4 refer to new shingles, but there are no specs for new asphalt shingles. Can those be provided?

We are patching a section of an existing roof and tying into an existing shingle. We would like the new to match the existing. We will attach a spec section for reference and bidding, but this will need to be evaluated and verified in the field to match existing when project is awarded/started.

5. Sound Membrane Specification:

· AE-101.3 Note #4 refers to a sound membrane. Can the VA provide the specification section for this? A/E will provide a basis of design for this product. A performance specification is not available.

Product Basis of design:

Mass Loaded Vinyl Sheet, install per manufacturers installation instructions.

Commercial Acoustics, Wall Blocker Sound Membrane Acoustimac, Soundlock

6. Resin Panels Specification:

· AF601 calls out for 3 Form and Lumicore resin panels. Can the VA provide the specification sections for these?

There is not a specification available. The resin panels are part of millwork components. Refer to the finish schedule for selections.

7. VA Logo Lobby Sign:

· For the VA Logo Lobby Sign, 1/4" deep seems thin for a pin-mounted logo. Can we propose using 1/2" brushed aluminum instead?

The larger part of the Logo (VA) can be 1/2” thickness and would benefit because of the mounting type. The 4” lettering can remain ¼” thickness

8. Underground Piping Demolition:

· PD100 - Is the sawcut, excavation, and demolition of underground piping only in the un-hatched area per the legend, or does it include the hatched area as well?

The hatching does not represent where to demolish the piping. The hatch is to illustrate what areas are slab-on-grade or if a basement is below.

Demolished piping and fixtures are illustrated in dashed bold linework on PD100 Sheet AD101 Detail 2 does illustrate estimated areas to demolish concrete/excavate to remove piping as required on PD100.

· How deep can we expect to find the items for demolition?

2’-5’ below slab (depending on location)
