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.
ANSWER:
Access control cabling, backboxes, and conduit are to be furnished and installed by
the contractor awarded this project per Y-001.

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.
