wardrobe instead of a standard finished cabinet top. There is also a note for PLAM

on moisture-resistant core (which is what we’d use for a shop-made laminate

countertop that had a sink in it). This is very unusual & also unnecessary for the

top of a 7-foot-tall cabinet. Is this correct or is it an error? Note that specs in 06 40

SUBJECT: Access Control Wiring


DWG./SPEC. REFERENCE: 28 13 00

QUESTION:

Spec Section 28 13 00 - Access Control (3.2A & 3.2B), states to the access control

integrator that cabling has been provided and installed by others and is coiled up in

the respective MDF/IDF room at the junction box at each door. This leads us to

believe that composite cables called for on the symbol legend found on drawing Y-

001 dated 7/27/18, are to be furnished & installed under BP#16. See attached

drawing Y-001, dated 7/27/18. The description for "CR" (card reader) included on

the security symbol legend, provides direction for installing composite cables to

each card reader, however goes on to state that "conduits and back boxes" shall be

provided & installed by the contractor awarded this project and refers us to

drawing T-200. The description does not state that the contractor awarded this

project is to provide and install the access control cables, as it does for other

symbols on the legend such as cameras. Lastly, the access control details found on

drawing Y-200, as referenced on the symbol legend on drawing Y-001, do not

show any cables in the conduits to accessible ceilings as the details for items where

cabling is clearly to be provided by BP#16 do (please see attached). Please clarify

if access control system cabling is to be furnished and installed under BP#16.

Access control cabling, backboxes, and conduit are to be furnished and installed by

QUESTION:The 3" CHWS&R and HWS&R lines in the Lobby (C105) have symbols on the pipes that seems to be tees, however, no piping is coming off of them (See area near the center of the oval X-Ref background)?

SUBJECT: Phasing of Sprinkler System

DISCIPLINE/TRADE: BP#13 – Fire Suppression


QUESTION:

Various sections of the building will be completed at different times. It is expected

that the sprinkler system will be tested but not live in the earlier phases of the

project or are their plans for temporary removal of ceilings to create access from

the sprinkler riser room to the second floor during phase 2 to allow the system to

be live at the completion of phase 2. (There were no plans in the phasing to include

the ceiling removal work.) Since there are currently no sprinklers in the building,

will the Fire Marshall allow occupancy in areas with inactive sprinklers?

ANSWER:

The Fire Marshall and the Building Official will require that as sections are turned

over that the fire sprinkler systems be activated in those areas. This is based on the

Ct Fire & Building codes that stipulate fire sprinklers in "E" use buildings, as they

will fall under the CT Fire & Building Codes for alterations and new

construction/renovations.
