- 2nd Floor Mezzanine Grids F 2 Layouts
Restroom Piping, Elevator 5, 6, Janitor Closet, Machine Room
Janet asked about changing the plumbing to accommodate space for a
Janitor closet that was formerly used for plumbing vents, above and
north of elevator 5, at the entry to the elevator equipment room.
Janet has confirmed with the elevator consultant that the elevator
shaft can be vented high on the wall at the ceiling rather than in
the ceiling.
The vent is located above the new janitor closet.
The elevator consultant has layed out the elevator machine room.
Robert notes that 3' - 4' working clearance is needed around the
elevator equipment.
- Fire Damper Access Ducts at E.5 - E.7 South of 2, Level 2 Mez
KH proposed design provides a catwalk access to the fire dampers.
Janet proposes putting a ladder in the Operable Wall enclosure.
Catwalk is at 27'4" above floor.
Need head clearance under ducts -- 6'8" +
No access is possible through the elevator equipment room.
Allen says ducts clear the beams.
Clonia says acoustical door is needed if access from moveable partition
storage enclosure.
Running the duct down to the ceiling of the toilet rooms, then back
up the roof (???) deck, was discussed.
This was not acceptable because of acoustic and ................
Clonia says okay.
Janet submitted to A&P a copy of the KH drawing showing the catwalk
and access to the fire damper.
Following the meeting it was decided to locate the catwalk access
from the mechanical penthouse above.
- Ivan advised of having submitted a design package to A&P on elevator
7 and 8.
KH is revising sketch that was included in the design package.
- Gas Meter Room Studied to Resolve Location/Space Issues
Allen advised that A&P is meeting at 1330 tomorrow with the City and the
Utility consultant.
Allen indicated that the design scheme for the gas meter room may
not work.
Clonia noted there is no place for a louver in the side wall -- ducts
must terminate in the soffit above.
This requires...
- 95' of exhaust duct.
- 75' of supply duct.
Allen noted that the duct length is too long.
Clonia proposes moving the room to the ground floor.
- Kitchen Grease Duct, Fire Rated Blanket Wrap, Cost Reduction
Allen suggests avoiding blanket wrap on vertical ducts per
discussion on
cost reduction at meeting on 981014.
Allen indicates a single layer wrap costs $5.50/SF for material, so a
double wrap costs $11.00/SF for the material.
Installed price is estimates to cost $19.00/SF.
Ivan asks if it is not necessary to extend the 2 hour shaft because
the ducts will be wrapped?
Michael discusses using duct wrap on long runs.
There is not enough clearance for the duct wrap.
Mentions "critical dimension" and "shaft wall."
Discusses using duct wrap horizontal and vertical because there is
not enough clearance to build a gyp board rated wall.
Allen notes that 4 grease ducts need wrap.
It was decided to use the grease duct wrap vertically due to area
constraints.
Clonia discusses writing a specification. It is a grey area whether
to specify duct wrap in the mechanical section or ..... (maybe
insulation)
- Coordinate Telecom Conduits
Robert asks about coordination between Telecom 4" conduits in the 1st
Floor Mechanical Mezzanine at line 4.3 and A5, following up meeting
with
Teecom at 0830 this morning.
Allen reviewed mechanical drawings for conflicts.
It appears that conduit clears ducts; not enough room for sweep to clear
the ceiling.
The telecom fiber optic conduit will have 2 bends in the
mechanical room.
Amit asks if the conduit can be put in a chase?
John says no.
Robert says conduit will be sealed.
Amit says A&P needs a drawing that shows the conduit runs, so that
ductwork can be layout to avoid the conduit.
- Access to Equipment - Catwalk; Elevator Machine Rooms
Allen submits a sketch of a typical detail for ......................
- Needs to hang outside the elevator machine room.
- There will be a supply duct, so there are 2 ducts.
- A&P needs access around it .............................
Robert asks Allen to point out on the drawings and in the A&P sketch
where access is needed.
Allen says normally need 36" all around.
- Electrical access panel is on the back side.
- Need access to a compressor.
- There are many things on the unit that require access.
Robert marks drawings to show where access is needed.
May need a catwalk because duct is high.
Allen says access for the filter can be from either side.
Allen draws a sketch in elevator mechanical room. Shows supply and return
ducts to illustrate access requirements.
Clonia asks why a catwalk is needed?
Allen suggests locating ...................... in mezzanine fan
room.
Robert says KH needs to provide plans of mechanical equipment rooms
for the elevator.
- Notes on Meetings with Fire Dep and Building Dep
John requests that Clonia submit notes of meetings that were held with
the City building department and with the Fire Department, last month.
Clonia recalls that the notes of these meetings were submitted to
A&P.
John does not recall receiving the notes.
Clonia asks Angelica to give A&P a copy of meeting notes #7.
Angelica says John should have gotten these notes.
Before the meeting today ends, Clonia submits notes of meeting with
Fire Department, to John.
John needs notes of meeting with Building Department.
- Notify Project Manager of Changes to Drawings
Restore Details on Drawings Requested by Project Manager
Clonia says some drawings have been changed without telling her.
Seems to instruct don't do anything on design of
elevators.........?
Clonia advises that backgrounds need to be revised.
Information needs to be restored to drawings that was removed.
Operable Partition Enclosure at F and 4.6 has been removed.
[Unclear if this is detail that needs to be replaced on
drawings.]
- KH Preparing Backgrounds for Consultants
There is discussion that A&P will receive backgrounds on 981026.
A&P will not necessarily fully apply all of the new information in
these backgrounds for the 50% CD set by the target date of 981030.
Amit explained the need to take the time required for careful
professional work that is well coordinated.
Robert explained that close coordination is needed between KH and
A&P.
Clonia advised that backgrounds on the west mezzanine will be
submitted to A&P prior to 981026, if they are available.
Amit asks for reflected ceiling showing substructure of Exhibit area.
Allen needs structure on B?
Allen asks about louvers for the 50% CD?
- Status of Issues from Mech Meeting on 981014
1- Pre Function
Amit discusses 2 slot and single slot diffusers.
Discusses need to pick a louver and submit it to A&P.
Amit says A&P needs diffuser types for Pre Function, per request at
meeting
on 9081014.
Clonia reports on having submitted a detail of a diffuser to
A&P, and that a copy was provided to Robert Rudeen.
Clonia indicates this needs to be in the 50% package.
Robert says KH has not received the submittal.
Clonia consults with Angelica and a copy is provided to KH
during the meeting.

per
discussion
on 981014.
Discussion about a stair.

4- Restroom Layout, Coordination with Plumbing, HVAC
Clonia wants concrete curb around restrooms.
This seems to have been discussed at the meeting on 981014...
ref SDS 14 5256
Robert seemed to explain there will be a terrazzo base, but
maybe not a concrete curb.
7- KH Reviews Detail to Solve Vent Shaft Elev 1 - 4
Pending????

Janet shows John a detail of solution from
meeting on 981014.
Allen is concerned about a code issue.

Robert seems to report on discussions with elevator consultant that
indicate vents can be on the side.
Vent is at ceiling in side wall.
8- Ductwork at Penthouse on Roof at Elevators 7 and 8
