17 A501 detail 2

A501 detail 2 - where plates are to be installed at removed piping locations, confirm thickness of deck system. Is there concrete or just terrazzo above the steel deck. Confirm there is no concrete at locations above steel deck - only finish flooring (or provide location / conditions that there is concrete above steel deck)

AOC Response:

Detail 2 on Sheet A501 shows a condition where 3/16" metal plate can be used to cover each side of a hole in the existing steel plate deck floors when existing sprinkler piping is removed from the decks. The existing steel plate deck is between 1/4" to 3/8" thick and may have cork composition tile or vinyl composition tile on the top surface. Contractor shall verify steel plate deck thickness in the field before installing covers to the holes in the decks. Cork composition tile or vinyl composition tile is the typical condition at the deck floors.

18 A501 detail 2

A501 detail 2 - to install new metal plates, will it be required to chip back the terrazzo flooring for the minimum 1" overlap.

AOC Response:

There is no terrazzo on the steel deck floors where this detail applies. When the piping is removed requiring the hole to be covered, no cork composition tile or vinyl composition tile needs to be chipped back. Any existing fire stopping that remains will likely need to be removed before covering the hole.

19 NA

Does the terrazzo flooring at standpipes have a setback from the existing opening / riser in the deck or does the pour abut the pipe?

AOC Response:

The existing conditions have firestopping between the visible flooring and the pipes. Most of the stairs within the stacks do not have terrazzo flooring at the landings; they have cork composition tile and vinyl composition tile as the floor finish. For the stairs that have terrazzo flooring, it is presumed that the terrazzo goes up to the opening as it may have been cut after the terrazzo was installed.

20 NA

Provide thickness of current terrazzo flooring.

AOC Response:

The thickness of the terrazzo floors is not known and is not identified in the Building Preservation Guide. Historic terrazzo systems could be up to 1/2" thick. Terrazzo is typcally poured over thick mortar beds or concrete. Terrazzo would not be power over the steel deck. While we do not have existing info on the terrazzo, we believe the terrazzo and concrete that is in the corner stairwells could be between 3" to 6".

21 NA

Is the terrazzo poured directly on the steel deck or is there a concrete sub straight

AOC Response:

Historic terrazzo systems could be up to 1/2" thick. Terrazzo is typically poured over thick mortar beds or concrete. Terrazzo would not be power over the steel deck. While we do not have existing info on the terrazzo, we believe the terrazzo and contrete that is in the corner stairwells could be between 3" to 6".

Attachment 4

Bid Pricing Schedule

What size pipe fittings are we to base our price for the Unit Price No. 2?

23 017419-3.03A

Advise location that a dumpster noted in 017419-3.03A or confirm it will be allowed on site or are we to use the existing facilities

AOC Response:

The project specification does not specifically indicate the use of a dumpster or the location. The contractor has been provided with staging areas. The contractor shall be responsible to develop appropriate means and methods to accomplish the work.

24 NA

Confirm we will be allowed to use the freight elevator to access all the decks. - The construction access plan only show the cellar and Deck 1 for material access / distribution. Also, please confirm we will be allowed to use the roll up door at Deck 2 to direct access the freight elevator as well.

AOC Response:

Yes, freight elevator is accessible to all deck levels. Rollup doors at Basement level (can be utilized provided that sufficient planning/coordination is provided to minimize garage access interruptions) and Ground level (permited with appropriate scheduling as this is a shared space) are available to the project team for loading/ unloading of materials. No storage is available for deliveries at the Ground level rollup doors. Deliveries will need to be staged and stored in the designated basement areas per plan.

25 NA

The technical proposal states an option to propose a better schedule.

Please clarify if the awarded Contract will be based on the offerors proposed schedule for performance or the schedule of performance in the Contract Documents / RFI responses.

AOC Response:

The QCM shall not work on another contract simultaneously with any other project. The AQCM shall not work on another contract when stepping in to fulfill the duties in QCM's absence.

30 NA

Clarify if there is any loading restrictions on the decks for material.

AOC Response:

Per the original building design load letter for JAB, the stack floors are rated at a uniform design live load of 120 pounds per square foot (psf).

Any concentrated loading would need to be looked at on a case by case basis by a Structural Engineer. To avoid a detailed structural analysis, the contractor could detail concentrated loads to be spread out over an area (with a base plate, cribbing, etc) so that the load applied to the floor would equate to the rated 120 psf allowable uniform load.

31 Factor 3

Factor 3: Prime Offeror Past Performance references an enclosed "AOC Past Performance Questionnaire for Prime Offeror," but we were unable to locate this document in the proposal attachments. This applies to both the prime offeror and the subcontractor. Could you kindly provide the PPQ form so we can distribute it for signatures.

AOC Response: The PPQ was incorporated and uploaded to SAM.gov as Attachment 10 via Amendment 03.

32 NA

Please consider granting an extension to the bid to allow sufficient time for the Past Performance Questionnaire (PPQ) form to be sent out, signed, and submitted to the contracting team (this form has not been issued yet).

AOC Response: The PPQ was incorporated and uploaded to SAM.gov as Attachment 10 via Amendment 03.

Phasing Note 4 on

A501

Detail 4

Terra cotta blocks in stairwells 1, 4, 5 and 8 at locations above deck 12 are lead containing as described in H112 and the Hazmat Report. Because of the lead, these blocks will need to be removed by an abatement subcontractor, not a masonry subcontractor who has expertise in the salvaging of existing material. Because these are to be ‘salvaged for reuse’, and considering the means/methods of how these will be removed due to the hazmat element, they are likely to be damaged in the process.

Would the AOC consider having the contractor plan on using attic stock at these locations in lieu of salvaged block – and should the existing block be able to be removed without damage, it could then can be reused.

AOC Response:

Per project details, the general contractor shall make all reasonable efforts to salvage the exisiting terra cotta block. There is limited attic stock available, therefore care must be taken in the removal of existing blocks so they may be reused to the greatest extent feasible. In the event a block is damaged, attick stock can be used.
