From: Robert Rudeen

Date: November 19, 1998
 

Subject:  Moscone Center Expansion, Phase III
                Mechanical Meeting Notes of November 12, 1998

Below are my comments regarding the Mechanical coordination meeting of November 12, 1998.

First question: Why is Kwan Henmi abbreviated to KHA when the other JV Team members are spelled out? It would be great to be on equal terms with the rest of the team.

Further, I was unaware that the meeting notes were being done by someone else until I received these notes on my desk, Monday. This is evidently a change to what had been agreed to in the past. The meeting notes that I had prepared were near completion. This duplication of effort is causing a delay in our work.

[On 981123 this concern is reviewed and aligned in the project record.]

Item 1:

Meeting notes should be clear on the location of a problem and what the problem is. This should be clarified. KH was directed to provide a section of the duct clearances at the ceilings as they meet grid F. A&P is changing the duct layout in this area and will submit a new plan.

[On 981123 this concern is reviewed and aligned in the project record.]

Item 2:

The reason for the drawing, which was given to the attendees of the meeting (not attached), was to confirm fire damper access to the ducts coming out of the duct shaft near the level of the elevator equipment room.

Item 4:

A&P was requested to confirm the dimension from grid line A to their equipment. The sketches of the area were handed out at the meeting. See attached.

Item 5: Clarification - The plumbing "shaft" is located in the west wall of the elevator vent shaft for elevators 7&8, at the same level as the elevator equipment room. No shaft was needed. KH to provide 6" studs in the west wall of the vent shaft.

Item 6:

KH did not request information about the elevator equipment room HVAC equipment. KH requested A&P to review the 50% set and confirm the location of the HVAC equipment for the elevator equipment rooms. During the meeting, we presented a plan of the equipment at elevator equipment room at elevators 5&6.

Item 7:

See item 1:

Item 8:

See item 1:

Item 10:

Just to clarify; this is a concrete shear wall. Plans were given to A&P during the meeting.

Item 12:

Clarification - These intake shafts are along Minna Street, grid 1. A two hour shaft bottom is needed at the bottom of the shaft that does not extend to the floor of the Basement Mechanical Room near grid C.5. A&P was requested to confirm the free area needed for the shafts along Minna Street.

Item 13:

Clarification - The new room will be taken from part of Area 003, grids B to B.3/2.6 to 3.

Item 14:

Please clarify. I don't recall discussing this, nor do I know where it is located.

Item 15:

Please clarify. I don't recall discussing this, nor do I know where it is located.

Item 16:

A&P requested support for an 18" water line, not an 8" water line. A&P should coordinate with Structural and confirm to us that the piping is adequately supported.

Item 17:

CC said she would review this with Structural.

Item 18:

Clarification: A&P requested the invert elevations of the drain lines so they can complete the Basement drainage.

Item 22:

The telecom conduit information was sent to A&P. No further action required from KH other than to backcheck A&P's drawings.

Item 23:

Please clarify where the fire damper access was discussed. I thought this item was resolved.

Item 24:

The curbs around the perimeter of the toilet rooms issue was for information. The curbs will be shown on the Structural Drawings. A&P will have piping that conflicts with the curbs and will require special details to get through or around them.


Previous Items

(Previous) Item 1:

I could not find this on the previous meeting notes. Gensler needs to identify the date and para of the document to which each previous reference pertains.

(Previous) Item 3:

Clarification - This is the Gas Meter Vault.

(Previous) Item 4:

I could not find this on the previous meeting notes.

(Previous) Item 5:

KH is studying the access to all fire dampers.

(Previous) Item 6:

I could not find this on the previous meeting notes.

(Previous) Item 8:

Please clarify the location of the Emergency Generator Exhaust. I could not find this on the previous meeting notes.

(Previous) Item 9:

KH is studying the location of the elevator exhaust vent for the elevator shafts of elevators 1,2,3,&4. I did not understand that we were to study shaft vents that did not terminate at the roof.

(Previous) Item 10:

I could not find this on the previous meeting notes.

(Previous) Item 11:

I could not find this on the previous meeting notes.

Item discussed that was not included in the meeting notes:

Water supply pipe locations for the Fire Hose Cabinets.

Recommendation: Number the "previously discussed items" differently than the "new" items. Example: 10-21.3 (This is the third new item that was discussed at the October 21st meeting.) Otherwise, it is difficult to track the "previous" issues when they keep changing numbers from week to week.
