Planning & Design Meetings Facilitites Review Meeting 2/22/2012 - MinutesFacilities and Maintenance Meeting Palo Alto High School 22 February 2012 Page 1 PALO ALTO HIGH SCHOOL Palo Alto Unified School District FACILITIES & MAINTENANCE MEETING DATE: 22 February 2012, 9:30 pm - 1:00 pm SUBJECT: Palo Alto High School Performing Arts Center ATTENDEES: Sign-in sheet (attached) The following are the highlights of the meeting: Introductions: 1. Aimee Lopez (AL) welcomed each facilities and maintenance group and introduced each group to the project through a PowerPoint presentation. She informed each group that the purpose of the meeting was to familiarize them with the scope of the project and it’s intended systems and to receive input regarding those systems and their operation and maintenance. Electrical (Information): 2. Discussion of electrical scope and systems proceeded as follows: • Oscar Louie (OL) reviewed electrical design with group including lighting, power, low-voltage and fire alarm. • Luis Zepeda (LZ) asked about extent of parking lot lighting scope. • OL stated that the only the area of new parking will be included in the PAC scope and that the remainder of the parking lot lighting will be handled as part of multiple other projects. All of the adjacent parking lot lighting, however, will be controlled out of the PAC. • Facilities and maintenance staff stated that parking lot lighting should be on Alerton system (EMS) and not time clocks or photo-sensors. WattStopper controls would be connected to Alerton system for monitoring. • OL stated that parking lot lighting would be approximately 16-20 feet high with pedestrian lighting approximately 12 feet high. Smaller/lower fixtures will require tighter spacing. • OL pointed out proposed location of main switch gear and new transformers (all in Electrical Room except new 1500 KVA transformer that will be immediately outside of electrical room in an enclosure. Transformer will be fed from boxy by Haymarket Theater (on loop 2). OL reviewed single line diagrams with group. • Group discussed ventilation of Electrical Room. Room will need to be ventilated well. Louvers will likely not provide sufficient ventilation and room will likely need to be mechanically ventilated. • OL pointed out location of IDF room. Fire Alarm Control Panel will likely also be in IDF room as well as clock/speaker panel. IDF will be on a rack against the wall. Nonetheless, OL stated that IDF room will need to be larger than is currently shown on the plan. • Group discussed data route to building and it was agreed that data would be Facilities and Maintenance Meeting Palo Alto High School 22 February 2012 Page 2 pulled from the MDF room (located in library) in a new fiber-optic line. • Access to lighting was discussed. Lighting in theater will be wall sconces or accessed by catwalks. Lobby will have LED lighting to make light replacement less frequent. • Group asked about type of emergency lighting. OL stated that emergency lighting would be on an inverter. • Fire alarm system was discussed. OL stated that heat detectors would be used on the stage. OL will coordinate with Shalleck regarding potential use of a beam detector for the house (and whether it would be set off by theater pyrotechnics). OL stated that he is still determining how the new fire alarm system will tie into the existing campus system. • Locations of wheelchair lifts were discussed. LZ asked if he could get cutsheets of proposed lifts. Brad Gunkel (BG) stated that DLM is still looking at lifts but that they will forward cutsheets once they have narrowed in on a make/model. • OL stated that a transformer would be necessary on the roof and asked if it could be covered with a roof overhang. Erwin Lee (EL) and BG stated that this could be accommodated. • Koli Boesch (LB) asked how new pump station in parking lot area will indicate failure. EL stated that there will be an alarm and that back-up will flow into the retention system. LZ asked if another pair of control wires could be run out to the pump for remote monitoring, possibly in conduit already extending to pump. EL stated that he would check into this option and report back. • EL stated that aisle seats in PAC will have integral lights. • Group stated that they wanted wifi in PAC house. • KB asked if site lights will have a bypass. OL says they will be on a separate circuit. LZ asked for a mechanical wind-up for site lights. OL says there will be an override for exterior lighting. Group mentioned a map of existing circuits. OL requested that he be provided with a copy of this map. • AL stated that classroom will need a separate, more local panel. Group agreed that Office 130 would be a good location for this panel. AL also stated that classroom will need local dimmer controls. EL stated that dimmer controls could be accommodated in casework. EL stated that DLM will send casework layout and dimmer location to AL for review. • KB asked for staggering of outlets at concession area to avoid overloading individual circuits. • AL stated that there should not be a range or hood at the concession but only room for a microwave. • EL clarified that smoke hatches will have power. • Mike Jacobs (MJ) asked that T5 lamps be the type that are turned when installed (not just push-in type) if possible. • KB asked for consideration of cost of replacement bulbs/tubes when specifying fixtures. Mechanical (Information): 3. Discussion of Mechanical scope and systems proceeded as follows: • John Chou (JC) reviewed mechanical design with group including unit-types, systems, duct routing, pipe routing and controls. • JC explained that two 100% outside air package units would be used to serve Facilities and Maintenance Meeting Palo Alto High School 22 February 2012 Page 3 stage area. Ducts would run from roof down chases to concrete plenum trenches that would feed stage area from below. AL stated that long trench run appeared costly and asked if an alternative duct route could be explored. EL and BG said that they would explore alternative routing and send AL revised plans. • Group expressed concern about ability to access return air grilles above stage and requested that grille locations be coordinated with catwalk. • JC reviewed house ventilation including duct chases and slot diffusers for front of house and fan coil unit location and vents at rear plenum; air supply will be under the seats. • JC stated that lobby will be fed from sidewalls from space above storage. • JC stated that ticket booth will be served by a separate small split system. Georgia Tolland (GT) stated that pipe routing would need to be coordinated, running on roof if necessary or in a furred out space so as to avoid its visibility in the lobby. • Group asked if dimming room would be separately ventilated and JC stated that it would need to be. • OL pointed out to JC that electrical room will need to be separately ventilated. • LZ requested that JC coordinates with Alerton to verify that EMS programming communicates properly between various systems. • AL requested that JC study means of reducing the longer runs and the number of different systems used on the building. JC agreed. • JC reviewed restroom exhaust fans. LZ asked that exhaust fans be on ceiling mounted occupancy sensors and that each restroom has its own fan. • Group stated that units should be Trane and not Carrier. • Group asked that convenience outlets and key-operated hosebibs be provided on the roof. • Group pointed out that another global controller may need to be added. JC to coordinate with Syserco and coordinate location with electrical. • Group reminded JC to coordinate diffuser locations with heat detectors so that fire alarm system is not triggered by HVAC. • Group asked JC to look at option of changing Green Room to a roof-top unit (instead of ceiling VRFCs that JC currently shows) for ease of maintenance. • GT asked if copper condensate lines on the roof are acceptable and group stated that they are. • Group expressed concern about VRF’s filters and the film replacement process. It can get messy when they are located underneath the unit and when the units are located in a location that can be obstructed by classroom furniture. Plumbing (Information): 4. Discussion of Plumbing scope and systems proceeded as follows: • GT reviewed plumbing design with group including fixtures, hot water heaters and pipe routing. • GT stated that there will be hot water in the restrooms including the multi- occupancy restrooms. • LZ stated that he does not want hot water heaters on EMS. • GT stated that hot water heaters would have a 7-day digital timer for circulation • AL asked about a shower in the Green Room. GT stated that, if there is to be a shower in the Green Room, she would likely use a gas-fired tank-less hot water Facilities and Maintenance Meeting Palo Alto High School 22 February 2012 Page 4 heater. • Group stated that either small (20 gallon) tank-type hot water heaters or 220V insta-hots be used for back area if no shower. Of those options, Joe (from goup) would prefer a 20 gallon tank-type hot water heater. • AL stated that drinking fountain at lobby should be chilled but not drinking fountain in back area by Green Room. GT stated that she will need a thicker wall behind the lobby drinking fountain to accommodate chiller. • GT reviewed fixtures. She stated that Chicago faucets are currently specified. Group stated that faucets at public restrooms need to accommodate adults better (greater depth). GT stated that all restroom faucets are shown to be metered. • Joe stated preference that urinals have strainer baskets if possible. • Group stated preference for adjustable in-wall primers for floor drains. • AL stated that public restroom isolation valves should be located in Custodial Room 132 and that isolation valves for back restrooms should be behind access panels in restroom walls. • Joe asked about cleanout locations and asked if more can be added to the project. • GT reviewed the sanitary sewer drain connections and explained there may not be enough fall on the system to accommodate the building’s systems. GT to review and calculate the current conditions and determined if a pump may be required. LZ explained that he preferred it if this was not pumped. Fire Suppression (Information): 5. Discussion of Fire Suppression scope and system proceeded as follows: • Moon Kang (MK) reviewed fire suppression design with group including fire riser location, site routing, hydrant locations and tie in to Media Arts Building backflow preventer. • AL and BG agreed that a follow-up review of the fire access and fire hydrant location plan should be scheduled with the Fire Department as soon as possible. BG said that he will prepare a Fire Access Plan, send it to AL. AL will set up a meeting with the Fire Department. • EL stated that DLM needs to send updated site plans to MK (MK’s drawing background was not current). • Fire Sprinkler zones was evaluated, and it was recommended that the PAC be on 2 zones (one for house and one for everything else). • AL requested that DLM investigate option of deleting one of the two new fire hydrants currently shown in the plans. Door Hardware (Information): 6. Discussion of Door Hardware proceeded as follows: • EL stated that hardware manufacturers and models have not changed from those reviewed by District in previous Schematic Design package. • Ken Culp (KC) requested that construction cores be left in place by contractor and that finish cores be delivered to District for installation (and that contractor cut keys). • BG stated that DLM is still updating door schedule and hardware groups and will provide District with revised schedule and groups as part of Schematic Design Facilities and Maintenance Meeting Palo Alto High School 22 February 2012 Page 5 package. KC stated that push-button hotel-style hardware should be used for the single-occupancy restroom. • KC stated that the IDF should have storeroom-type hardware. • EL stated that the roll-up door will only have a slide bolt on the interior side – no exterior lock. Finishes (Information): 7. Discussion of finishes proceeded as follows: • BG presented an exterior color diagram showing District Standard colors. • EL asked if public restrooms could be tile. • AL stated that they could not be and that they needed to be epoxy. • EL stated that carpet tile will be used in the Lobby. • EL stated that carpet will be in the aisles of the house and that sealed concrete will be elsewhere. • AL stated that louvers should be painted the same colors as walls and not accent colors.
