E. Approval of Old Pool Roof/AHU 95%
SA turned the discussion over to KS who gave a brief overview of the project.
PM Is this an all new roof and AHU?
KS yes. A1202 shows roof above the Commons where windows will be
removed and a curb put in.
PM The intent is to remove the windows, resize the opening and replace the
windows? Will they be fixed windows?
SA It's not really clear from the drawings.
PM See detail 4 on A1801 and A1802?
SA There are no dimensions on the windows.
PM There's a plus or minus 4 ft. to concrete.

SA I'm not really impressed.
PM I can understand why it would be hard to determine the size.
PM On 1802-see the existing insulation. They've raised the height of the sill
and reduced the size of the window. Must be leaving the size up to the
Contractor.
SA Yes, but the window is just sitting on shims.
PM I think we need to have Tony Yorba spell it out.
SA I'm having issues with the way the window is sitting there.
PM Is there a top view?
SA I don't see one. I want to see one.
KS It says it's approximately 2'4" wide, shortening the window a foot, 4'7" to
sill.
PM Here's the head detail. That has a better attachment than the bottom.
SA on 182 demo-remove the existing insulation-I'm not seeing what goes
back into the space.
PM Welding together, but what's the void?
GH It has to have something in there. See detail A1802, Detail 1 Insulation,
better ask Tony. A1802 Detail 4, the sill detail-between aluminum mullion and
structural sill, needs to show attachments, better detail.
KS calls Tony Yorba.
SA Tony on A1201, please walk us through.. .
TY I have to boot up my computer. Call me back in 5 minutes.
SA OK.
SA I'll read Scott Bonney's comments...
A801, Section 1 he is questioning the use of OSB. TY has allowed the
use of Versaboard instead of OSB. We need to have TY spec this instead of
OSB.
A801 Section 4 he's questioning the clip type. Afraid that it will leak.
Wants better detail
PM I don't think that's an area to be concerned about. It's usually done in a
way that it's really tight.

GH There's no insulation at all?
PM There should be some in the void.
SA Ken please try to call TY again.
TY back on telephone
SA Let's start at A1201- it shows window wall. There's no frontal view.
TY There's a section view.
SA A1801
TY Detail 1 is typical demo, drawings indicate that the exterior slab is sloped.
It will be taken to bare concrete. Detail 2 is the roof to wall on the auditorium
side. There's 1 1 /8" plywood over a concrete deck. That will remain. The old
EPDM flashing needs to be removed. The wall panel will be cut in order to
raise the roof deck. Detail 3 is the side facing the alley between the
maintenance building and the pool. I will have to check the asbuilt regarding
the void. Detail 6-there's a serious problem that is basically unsolvable
regarding the existing wall panel. The wall panels all leak because of vertical
joints. There is nothing that can be done. Can't put a spring lock regulator on,
it will still leak. The plan is to cut it off at the bottom of the panel and re-
stnacture to stop the leaking. A1802 Detail 1 & 4- head and sill condition at
the window-the original neoprene windows. Disassemble a short section of
wall panel. Need to raise the sill. There's a steel angle on Detail 1, to the
inside face of the wall panel. Vertical steel mullion and aluminum to remain. It
keeps the window assembly in place. Detail 2 shows the neoprene frames
with a "U" shaped piece of steel structure. It's identical to the Library. Detail
5-the drawings indicate that the lower section of the louver is a dummy piece.
GH That's correct.
TY So we'll take that out and have room to attach to the roof with no leaks.
There will be a little inside demo to get access to the window framing. A201
Detail-Overall roof demo plan. Reuse all roof drains, assumed that sloped
concrete deck will work for drainage. Also shown are the dimensions of the
louvers and rectangle for new AHU. There's an expansion joint at gridline 16.
Gridline 15 is the gym, there's no expansion joint.
SA No questions
TY A201 is the plan view of the windows. I detailed a typical mullion. A801
Detail 1 is the typical roof assembly. Concrete deck, hot mop with asphalt,
vapor barrier, covered with two part epoxy.
SA What kind of paper?

TY It's a roofing type, not regular. I think this will work really well with the
concrete deck. Then EPS, then OSB and membrane.
SA We have a problem with OSB. You have allowed Versaboard before.
TY Yes, but all the manufacturers are going back to OSB.
SA It (Versaboard) absorbs no water.
TY All the roofing guys are going back to OSB, but I'll check and if
manufacturers still support I'll spec it out.
PM The roofing manufacturer warranty will drive what the roofing contractor is
will to install.
TY There are a couple of products I will not allow.
SA I'm uncomfortable with OSB.
TY OSB is actually performing better than plywood.
SA Roof membrane?
TY 80 mil PVC.
TY On some other projects I have been allowing TPO, but I don't think you
want that.
SA Correct, PVC.
SA The existing hat channel, you show it being re-used. How flexible is the
siding?
TY They just have to back the screws out until they can get it in place to hold
the membrane. Maybe we could put a neoprene closer strip in there?
SA Yes that's a good idea.
TY They will paint the raw end of the steel wall panel.
KS Is that a 4 x 8?
TY Yes, pressure treated.
KS How is it connected to the plywood?
TY I don't know.
SA Depending on how it's anchored, you could have them screw into the
plywood.
PM You could use A35 clips.

SA Insulation over 1 1/8"? 1 1/8" is only 4 foot out. What about the transition?
TY I thought I'd just have them shave it to taper.
TY Detail 3 is the revised parapet. I am calling out a plywood subbase. I am
trying to get more height on the parapet then install flashing on it.
SA Cedar shims?
TY It will be solid.
PM Like a continuous cant strip?
SA How thick?
TY I was thinking of beveled cedar siding.
TY I'll call out 5/4's.
SA It looks like the membrane and flashing are pretty heavy duty.
TY OK, detail 4-curb for new AHU. I tried to build up something to support the
unit and tie down to solid roof.
PM That void in detail 4 page 801?
TY That should be insulated. I'll change that. Maybe I could use apre-
manufactured header that is pre-insulated?
PM Actually the plywood details look very strong.
SA SB notes question about gap around bolt in the insulation.
TY All voids will be filled with foam or something cut to fit.
TY Detail 5 is a short section of wall by the dog leg on the auditorium side. It's
a place for flashing. Detail 6-cut back insulated wall panel. The intention is to
replicate the original design on the other side of the building. Install a
structural pony wall underneath the wall panel when cut, for added structural
integrity. Pony wall on top with a continuous steel angle helps transfer load
from panel to pony wall.
SA Are we putting foam insulation in?
TY Yes, I will show that.
SA Foam rather than fiberglass because of losing the R-value.
TY It will be hard to push rigid insulation into that space.
PM Yes it will.

GH You said 4", but it comes in 2" panels.
TY I'll have to re-draw that. I'll have to talk to Chris Gianotti about that. The
original design was to have steel angles quick bolted back to the curb. It will
still have plywood. I'll have to solve the insulation issue. I'm trying to avoid
any kind of sill issue. The problem is that the insulation has to be wrapped
because of the fire issue.
GH The CMU's won't allow you to get there on the backside. The details all
show 4" Robertson panels instead of 2".
SA 6a for curb and louver detail is missing?
PM It will be the same.
TY Yes I need a new detail at the louver.
GH On A802?
TY Yes.
TY Windows-have to verify front end? Detail 1-concrete spandrel is notched
around the steel framing.
SA You're intending to fill the void above the window?
TY Yes, I missed that. I'll fix it.
GH Detail 1 shows spray on insulation on the red iron. We could have
asbestos issues.
TY I don't think so. I won't be opening anything up. I'll check it again.
TY KS you gave me some .pdf's of abatement drawings?
KS Yes.
TY I'll modify that detail a little, adjust the angles in field to support window
head. Detail 4 shows the bottom of the window opening.
SA The window sill-the window is flat with the neoprene shim. What's the
connection?
TY I'll double check the connection. The aluminum windows are all flat. We
do need to allow for water to weep. We used the shims to do that. We will
line the bottom with PVC membrane welded to flashing and anchored to
treated sill below.
PM All the new windows are like that now.
TY I wont' about moss build up in there. I need to re-draw the sill to widen it
for proper bearing.

Everyone agrees.
SA What's your thought? Should we approve tonight or do you want to bring
the revisions in May for approval?
TY I'd like to finish tonight.
KS Let's look at the mechanical.
SA We're tying to the existing? With an AHU similar to the rest of the
District's?
KS I found the specs for the existing. We're just upgrading.
KS Ventilation requirements for the pool and the gym are the same.
TY Yes.
GH the insulating value of the box itself, the AHU?]
TY I'm not seeing it. I'll have to check on that.
GH I don't see the exterior finish spec either.
PM I found it on M001.
GH There's the insulation too.
TY The polyurethane is great. I'd rather have a Kynar finish, but I don't think
it's available. Any other questions?
All say no.
TY leaves the meeting.
SA I would entertain a motion to accept the 95% plans.
GH So motioned.
PM Second.
Unanimous vote.
