- 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 grid 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 cost.
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 catwalk 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.
Considered using blanket wrap for horizontal and vertical ducts because
there is not enough clearance to build a gyp board rated shaft 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 create its own
section.
- Coordinate Telecom Conduits
Robert asks about coordination between Telecom 4" conduits in the 1st
Floor Mechanical Mezzanine at line A.5/4.3, following up meeting with
Teecom at 0830 this morning.
Allen reviewed mechanical drawings for conflicts.
Amit says A&P needs a drawing that shows the conduit runs, so that
ductwork can be layed out to avoid the conduit.
- Elevator Machine Rooms HVAC Equipment
Allen submits a catalog cut of an air handler, that is reviewed during
the meeting for access...
- Needs to hang outside the elevator machine room.
- There will be a supply duct and a return air duct.
- 36" wide access needed on 2 sides.
- Electrical access panel.
- Compressor requires access.
- Filter requires access that can be from
either side.
- Notes on Meetings with Fire Dep and Building Dep
John requested Clonia's notes on meetings with the City building
department and Fire Department, last month.
Clonia gave John notes of meeting with Fire Department.
- KH Preparing Backgrounds for Consultants
A&P will receive backgrounds on 981026.
A&P will not have adequate time to incorporate all of the changes for the
981030 printing.
Amit asks for reflected ceiling showing substructure of Exhibit area.
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.
- Status of Issues from Mech Meeting on 981014
1- Pre Function
Allen asked for a copy of 2 slot louver, following up
discussion at the
meeting
on 9081014.
Clonia gave Allen a copy of the louver information during the meeting
today.
2- Mechanical Shaft in Basement Level
Allen asks if a shaft should stop at the ceiling at line C5?
per
discussion
on 981014.
KH is reviewing this matter and impact on design of stair.
4- Restroom Layout, Coordination with Plumbing, HVAC
Clonia requested concrete curb around restrooms, as discussed at the
meeting on 981014.
Robert advised that there is a terrazzo base.
Clonia said she still wants the concrete curbs.
