Also present were Woody Koning, Ken Smith and Jessica Wolfe representing the KIB; Tony Yorba, Jensen Yorba Lott, Inc. C. Approval of Agenda GH made a motion to approve the agenda. PM seconded the motion. Roll call vote was unanimous. D. Approval of Minutes GH motioned to approve the minutes of 1/28/09 as submitted. PM seconded the motion. Roll call vote was unanimous. E. 95% Review East Elementary Windows/HVAC SA turned the discussion over to TY. TY The report developed on the cost of adding roof top vents showed that this will be cost prohibitive. It was then decided to add the existing CAB unit vents to the window project. This project includes replacement of windows on outside wall; new windows will be of reduced size with operable lights; windows will be vinyl, one opening per classroom. The durability of slider windows offset the extra air infiltration. SA asked for clarification on window size and what advantage there was to using 6 foot versus 5 foot. TY this will cut down on the framing costs to fill the existing hole. SA small windows are very expensive. PM said that slider should be kept small. He also commented that it is necessary to keep as much natural light as possible. ARB Minutes 090225 East95%, Old Harbor 65%,Larsen Bay roof report.docx Page 1 of 9 JF asked about the U Factor? He suggested that we go with a window with a .30 U Factor. TY agreed with JF. JF discussed not caulking the complete bottom of the slider window due to the fact that all windows leak and this allows for drainage and helps alleviate rot problems in the sill. TY I will add an isometric detail that will show that. SA What about an additive alternate for pricing out triple pane? TY I can't see that that would be cost effective. SA What brand of windows are you looking at? TY Something generic. Alpine, CertainTeed or Milguard JF I didn't see anything adding low expanding foam after the installation TY I'll add that. TY As far as I can tell these windows seldom, if ever, get water on them due to the overhang. There is significant dry rot under the windows on the addition wing. Those are more exposed to water. We are looking at adding those windows to this project. JF I see that the trim is painted 1 x 4? TY That's to match the existing. SA Are you spec'ing out cedar? TY Dougfir JF Maybe cement board? SA I've had good luck with spruce/fir. WK Not cedar! Our best bet would be shop primed lumber; kiln dried, primed on 6 sides, delivered. TY Spec. section 09912 should be the paint specs. I will specify shop primed. SA Will there be siding work to do to replace these windows? TY No, not on the sides. The panels below will have to be removed for the louvers. JF Didn't Mike Sweeney have to do a lot of rot repair the last time he painted the building? SA Yes, he did. KS the windows we're adding will have siding that will need to be replaced. WK Do the remainder of the classrooms that are not in the project have the same windows? GH No, but we didn't look at them. TY The windows on grid line 20 are all steamed up and the seals are gone. We'll check the rest of them tomorrow. ARB Minutes 090225 East95%, Old Harbor 65%,Larsen Bay roof report.docx Page2of9 TY We did check on the roof and I don't see that the water damage to the windows is coming from the roof. GH The gutter on the roof is bad. TY It's a 15 year old EPDM roof. Adhesives are in acceptable condition. The seams are starting to crack at the overlaps. I found a few soft spots where water is getting in and on active leak. The gutter is a bad configuration. The mansard on the raised area, I've never seen anything like that before. There are some roof issues, but nothing that has to be done now. It should be put on the list to be done within four years or so. You should put it on the CIP list. GH The last work done was in 1994. The whole roof on the original building was replaced. TY M001 shows the typical unit. GH Should there be protection put around it? GH Is the information about horsepower and cfm a typo? It needs to be checked because of the new electrical panel connection. TY do you want to do the bathroom fans? GH I'll get with you tomorrow about that. TY M201 new installation, there's a problem with the layout of the circuits. There's a conflict between what's on the panel and what's on the electrical schedule. I'll have the engineer fix that. KS The load calculations list UV1 twice. TY I'll have the engineer fix that. GH The amp draw is matching with the lower horsepower unit. TY I'll have the engineer check on that. GH In specification 15510-5 it speaks to flushing and refilling with glycol. It's not a glycol system. It's just treated domestic water. The filter units are a MERV7. We think that's a HEPA which we don't need. GH We need to see if TRAN units are designed for glycol or water. Do the louvers "fail" to closed position? TY I'll check on that. SA We're replacing the actuators on dampers on the roof? GH There will be two systems. SA Are we moving towards standardizing? GH Not really. SA What's the budget for this? KS $137,000 for the seismic and $250,000 for the HVAC. WK The rotten windows seem more important. SA I was just wondering if there would be enough money to do all the unit heaters. ARB Minutes 090225 East95%, Old Harbor 65%,Larsen Bay roof report.docx Page 3 of 9 KS How will we price the rot? Unit prices? TY I'll try to spec it out in detail. SA What was the estimated cost for the original scope? TY I don't remember. KS $137,000 SA It seems like we should put the rest of the windows in as an additive alternate in case there's enough money. KS/WK That's a good idea. JF What kind of insulation? TY Fiberglass batt. I'll show it on the details on A1302. JF I suggest R13 high density instead of R11 regular fiberglass. TY I'll also change to friction fixture. WK What about this cutting and patching of carpet? TY I assumed you had some extra carpet. GH No we don't. TY We took some ACM samples for testing. We're waiting for the results. WK Is there a way to nail that down? GH It should be in the HERA report. TY There were other sealants. Some of the sealants at KMS had ACM. We might need to test the sealant on the windows. WK What condition is the carpet in? GH It's pretty bad. SA It's carpet over VCT/ACM. JF What about'/" plywood with vinyl over it? TY I'll look and take measurements of the existing heaters and see what we can do. SA Can you have these things done by next Wednesday? TY Yes I can. SA I would feel more comfortable approving a 95% design with these corrections made. TY OK, I'll do it. F. Old Harbor 65% drawings 6:50 pm Old Harbor 65% TY There's a 2000 gallon oil tank that's scheduled for removal. A shed to be demolished. SA Change from slab to shop and remove basketball court. TY At the backside of the gym there's a drainage issue. The manhole is a storm water lift station that drains under the building and off site. I need to show where it goes. ARB Minutes 090225 East95%, Old Harbor 65%,Larsen Bay roof report.docx Page 4 of 9 KS It goes into the berm in the back. TY We'll re-grade the back of the building and add a catch basin. WK It shows removing the old tank. Can we decommission it in place instead of removing? PM It would be much better to leave in place and a lot cheaper. TY A100a shows a new catch basin and culvert to the existing manhole. SA If it freezes where would the water go? TY It would pond in the same spot. 1 could possibly change the slope of the drain. I could put a heat trace on it to keep it thawed. It's four foot right now. WK What's the expense of heat tape? SA A lot. TY The shop is a slab on grade with a ramp leading out to 3 Saints Ave. We will be gutting the VocEd room and the toilet rooms. The operable partition and floor in the gym will be removed along with the overhead track. The gym floor has two layers of underlayment. The subfloor will be removed down to the original subfloor to get a good substrate then add new underlayment and new sheet floor. JF Do you use the expanding foam before putting the underlayment down? It's a drywall subfloor adhesive called ProFoam. It's an expanding foam adhesive. SA How would you get full adhesion on a sheet of plywood. PM It works really well. When it compresses it fills the gaps. JF It won't come apart. TY Maybe we shouldn't use it then. GH I remember two layers of carpet, not one layer of vinyl and one layer of carpet. TY I'll have to check that. There is ACM in the shop only. The floor will be mondo-synthetic the same as North Star. It will be a sole source manufacturer for the gym flooring. TY We will demo the existing vestibule. Detail #3 is an aluminum vet for the existing crawlspace. I'll make sure it is replaced elsewhere for the crawlspace ventilation. I'm going to remove the wooden decking outside and overlay with plywood. A102 Shows the existing fan room with mechanical equipment to be removed and doors to be taken out. We are not re-using the mechanical equipment. The specs describe re-using mechanical equipment, I'll have that fixed. The specs describe the demolition and disposal in Division 1. The CAM will need to come back to the landfill in Kodiak. SA I see one existing flue. Are there three or four? Do they all go? TY They all come out. We'll correct that on the mechanical demo page. GH The flooring is fuel soaked in that room. What should we do about that? ARB Minutes 090225 East95%, Old Harbor 65%,Larsen Bay roof report.docx Page 5 of 9 TY I'm not sure what to do exactly. If it's structural and it's cut out you'll lose the integrity. Maybe put a layer over the top of it. Just put down plywood and paint. All the fuel equipment is coming out of there. There will only be the air handling equipment it the room. PM There may be code requirements. WK There may be a sealer that can be put on it. JF An oil based paint will probably work. TY I'll check with the structural engineer to see what the implications would be. PM You might be able to put a hardi board underlayment. That would give you fire protection. TY The first choice would be to remove and reinstall. If we can't do that then seal or block it. The first concern is fire, the second concern is smell. TY The roof: leave the existing EPDM and remove the exposed insulation. TY The existing VocEd is divided into a training room, mechanical room and Industrial Arts storage. Scott Williams has been working with the Old Harbor people to maximize the functionality of the space. We will need to install welding booths, hose and electrical reels overhead and hose bibs inside and outside. SA Reels would be 110 volt so you will need a 220 volt area for the welding equipment. TY That's on the back wall. TY The door 110A & 111A are just wide enough for the'/2 diagonal distance that is required. It was really close. GH hands out a Scott Williams drawing for the space. SA Asked TY if he disagreed with the proposed configuration of the space? TY The use of VocEd funds to enlarge the training room is not a proper way to use those funds. It will not enhance the VocEd opportunities for the students. TY There will be a new structural wall between the new and existing building to alleviate problems. JF Are there any specifications for installing a pan under the thresholds on the exterior doors? TY I will need a detail...l'll look into it. TY We intend on putting a sink on the outside of the Industrial Arts office. Also a plastic eye wash station and eye protection cabinet and hooks for clothes. That will be under the mezzanine. We will also provide a storage cabinet for flammables. SA The storage mezzanine should show access to some of the space where the ceiling is 20 foot. TY Yes, that's a good point. I'll have to figure that out. GH How close are we to the maximum allowable square footage? TY I'm sure the mezzanine puts us over. I'll have to check. ARB Minutes 090225 East95%, Old Harbor 65%,Larsen Bay roof report.docx Page 6 of 9 TY The roof replacement: I looked at metal on the whole roof, but decided to do membrane after looking at Larsen Bay. JF A203 is showing two stacks? TY That needs to be moved. The drawings are not quite there yet. GH A301 shows the two stacks also. The mechanical drawings show side stacks. TY They should be side wall penetrations. I'll get that fixed. TY We're using vertical metal siding. I haven't speed it yet. SA What gauge are you planning on? TY 24 gauge at least. TY I need to check with the structural engineer on A301 about the lower back of the building. I didn't think it was necessary. Also, existing stacks will need to be patched after demo. GH It looks like the supply air is coming through the side wall. TY The roof penetrations much be from the bathrooms? I'll see if we can eliminate any roof openings. GH Let's pull the existing fuel pipe off the building. TY I'll have to check that. TY I'll need to check on where the tank is in relationship to the new building/slab/backfill/over excavation. A303 needs to show a footing detail where the old meets the new. JF The minimum insulation for the roof is R42, but I recommend R60. Also it should get some fiberglass put under the existing gym floor if possible. TY It can't be done because of a bunch of exposed piping. There is already perimeter insulation. JF Perimeter insulation doesn't matter if there's an exposed floor. If you insulate the floor you slow down the thermal transfer into the crawlspace. WK Metal buildings with overhangs get pitting under the overhang. TY I'll have to have 2-3" for the attic ventilation, but I'll do it that way if it's better. Everyone agreed to remove the overhang. TY A803-the parapet detail 1 needs to be fixed. It will be a cripple wall. SA I have a problem with zee flashings. TY I could put plywood behind the zee flashing then bitchethane on the face, no nailing into the face of the zee flashing. I think I need to move the siding out and drop it down. SA The roof vent against the existing gym wall: we should put new siding on that wall. TY That would make that detail a lot easier. That's a good idea. SA The existing roof sheathing: I see that you're leaving the existing foam. ARB Minutes 090225 East95%, Old Harbor 65%,Larsen Bay roof report.docx Page 7 of 9 Ty I believe that the EPDM was installed over an original torch down/built up roof. I believe it is solid enough to install over it. I have drawings that show an original asphalt roof. SA The bathrooms are gross. TY I could assume that the underlayment/structural plywood is bad. TY I don't want to put a drain in the slab. We have some coordination to so with the mechanical and electrical. SA We're going to stop the meeting at 9 pm. WK What does that do to the schedule? TY If we make the changes from Scott Williams' drawings we will be way behind. TY I am trying to have the 95% done by the 15tH TY A801 shows the demo and existing gym floor and roof details. GH There's two layers of carpet. TY The mechanically fastened PVC roof has the same warranty as the fully adhered. TY M101 detail 2 shows demo the existing vent piping, but the drawing looks like it stays. I'll have that fixed. M201 shows modifying the piping to relocate the sink. I'll remove the floor drain in the shop. SA Are there double doors in the mechanical room? TY I will change that to a single door if the equipment will fit. I'll put the double door from the mechanical room to the storage room with an in-swing. WK What about art equipment? A kiln, etc? TY There's been no discussion of it. TY M302 is missing. M401 has the new air handlers. I'll check on the wall exhaust in the bath. M301 shows the unit heater in the new VocEd room. M401 something isn't quite right about the drawing. I'll check with the engineer. I see some real problems and would also like to get rid of the roof hoods. The eyewash sink is going away. GH Please show a better detail of the fuel oil connection where it ties into the existing. TY Yes I'll have him do that. SA We will stop for now and continue next Wednesday, March 5, at 5:30 pm. G.
