Executive Summary Originally known as Assembly Hall, Freeborn hall was constructed in 1961. The structure and the exterior envelop have changed very little since originally constructed. The interior finishes have experienced some minor upgrades, but much of the hall is original. Over the last fifty#two years, there have been many renovations and upgrades. These projects have been cataloged, with a brief description of the work, in Appendix B. The hall is functioning on a daily basis. This report gives the current status of all systems and finishes throughout Freeborn Hall. Our recommendations are based on the program remaining the same in each area. Because it is unknown what seismic solution will ultimately be administered, we have not addressed that part of the recommendations. This assessment of the building Mechanical, Electrical and Plumbing (MEP) systems evaluates the ability of the existing systems to support the proposed building modifications. It is based on a review of the available record drawings, field verification, and discussions with the Building Maintenance Services (BMS) personnel. A list with contact information for BMS personnel is included in Appendix C. It was prepared by in# house, state licensed, professional mechanical and electrical engineers, and is organized as outlined in the Table of Contents. The MEP systems assessment describes the general type, layout and condition of each system and it provides recommendations for work needed under this project. The equipment condition was assessed on a three#tier scale: good, serviceable and poor. The general thought is that equipment in good condition can continue to serve the building and no work would be required under this project. Similarly, equipment in serviceable condition would require some repair and upgrade while equipment in poor condition would require major overhaul or complete replacement. In some cases, where the condition of a system or its components could not be verified, the recommendation is to perform additional verification and evaluation. This applies mainly to underground drainage piping and equipment located in ceiling areas with difficult access. 1

1. Architectural System Exterior 1.1 Roof 1.1.1 Roof Description Building Systems The existing copper roof was installed in 1961. It is an approximately 35,000 sq. standing seam roof, constructed of 16 oz. copper roofing on top of asphalt saturated felt, 1 ½ rigid fiberglass insulation BD., and 1 ½ steel roof deck. The roof protrudes from the building at a distance ranging from 10 2 and to 38, with eves that have plaster soffits on the underside. The roof is complete with a smoke hatch over the stage. 1.1.2 Roof Condition The roof has held up well over the years and has 30 / 40 years of useful life left. However, there are a few minor issues. The solder around the drains has broken/down or cracked at all twelve down spout locations on the building s north and south face (Roof Photo #1 For all photographs Appendix A) There appears to be minor repair work done at the high point between each down spout. There are two known leaks inside the building in the stage area. These leaks are possibly originating at the smoke hatch, located above the stage at the west end of the building (Roof Photo #2). The roof jacks are in various states of repair, but none appear to be letting water into the building. The plaster soffit under the eve is in very good condition with few areas that need repair. 1.1.3 Roof Recommendation 1.2 Exterior Brick Replace and re/solder the down spouts at all twelve locations including seams surrounding these areas. Remove and re/attach smoke hatch with new copper flashing. Check all roof jacks for repair if needed. Clean to remove bird droppings without removing patina. Clean plaster soffit and repair any cracks. 1.2.1 Exterior Brick Description The four corners, and back exterior wall, of Freeborn Hall are fabricated of brick veneer over concrete. The bricks are 12 x 4 x 2. The brick veneers are laid in a stack pattern with a 2 x 1 1/2 reveal every 4, with standard mortar joints. There is an exterior brick screen wall on the north side of the building. The wall is laid in a stack pattern with cross laid area to create other patterns. 2

1.2.2 Exterior Brick Condition Brick veneer exterior appears to be in good structural condition. Bricks are solid with very few cracks. Mortar is intact and does not appear to need pointing up. However, there is effervescence coming out in various parts of the building and screen walls. (Brick Photo #1) There are other areas that have paint overspray and other colored materials on the brink. This is especially evident at the ticket office windows (Brick Photo #2). There are few locations where items have been removed from the surface of the brick and holes remain (Brick Photo #3). 1.2.3 Exterior Brick Recommendation 1.3 Exterior Doors Clean all brick surfaces with an industrial level cleaner. Repair and replace any damaged bricks, especially in the areas where items have been removed from the bricks. Clean off overspray from needed areas. Replace any bricks that are damaged because of other upgrades. 1.3.1 Exterior Doors Description All the exterior doors are hollow metal doors. The exterior doors on the north and south sides of the building are incorporated into the curtain wall. Each side has 3 sets of double doors. The south side has one extra set of doors that goes into the stairway area. The north side has an extra single door also into the stairway area. The east entrance of the building has 4 sets of double doors. The west, back of the building only has one single door and a roll/up door (discussed in a separate section). 1.3.2 Exterior Doors Condition The hollow metal doors around the exterior of the building are in different stages of decay (Ex. Door Photo #1 & 2). The doors at the north screen wall are past their useful life (Ex. Door Photo #3). The main entrance doors are damaged and many are rusting at the base (Ex. Door Photo #4). Some of handles on these doors are mismatched, some wood and some plastic (Ex. Door Photo #5). The aluminum doors appear to be in fair to good condition. 1.3.3 Exterior Doors Recommendation Replace all hollow metal doors on the building. Assess the frames on a case/ by/case basis. If decay is extensive, replace hollow metal frame and door. Replace hollow metal doors and frames at north screen wall with galvanized steel gates with plate stock for privacy. Refurbish and update hardware on aluminum doors as required. 3

1.4 Curtain Wall with Insulated Metal Panels 1.4.1 Curtain Wall with Insulated Metal Panels Description On the north and south elevations of the building, the outer envelope mainly consists of aluminum curtain walls with insulated metal panels with porcelain enameled exterior and galvanized sheet metal interior. The east elevation has curtain wall from the ground to the roof for the center section. This curtain wall area incorporates the main entrance. This area is primarily glazed with ¼ inch plate glass. In 1977, the lower level glass was replaced with tempered glass per an OSHA upgrade. 1.4.2 Curtain Wall with Insulated Panels Condition The condition the curtain wall varies. At many locations on the north side, the base is coming apart. There are many locations where the gaskets are coming out (Curtain Wall Photo #1). It appears over the years some of the panels have been replaced with a different white metal (Curtain Wall Photo #2). The south side is in better condition than the north; however it still needs to be updated. The metal panels are intact on the east entrance elevation. 1.4.3 Curtail Wall with Insulated Panels Recommendation Clean all aluminum mullions and muttons. Replace all aluminum panels with insulated aluminum panels. Replace all glazing with insulated glass. Only the east elevation above the exterior canopy would need low/e glass. 1.5 Exterior Concrete North Yard 1.5.1 Exterior Concrete Description The north yard is exposed aggregate, poured in place concrete panels, with redwood dividers. 1.5.2 Exterior Concrete Condition The exposed aggregate concrete in the north yard area is deteriorating (Exterior Concrete Photos #1 & 2).

The condition of the Sanitary Sewer and Storm Drain is currently unknown. The Building Maintenance Services (BMS) personnel have reported that some pipe 25

sections do not drain adequately. A detailed camera inspection should be performed to determine the exact condition of piping and required work scope. 3.2 Site Utilities Recommendations Upgrade the Domestic Water service to current campus/standard configuration. This includes the addition of a backflow preventer and a water meter. These devices should be installed in the landscaped area at the west side of the building. Upgrade the Fire Water service to current campus/standard configuration. This includes the removal of the Post Indicator Valve (PIV) and the addition of a backflow preventer to replace the existing one located in the Basement Mechanical Room # 3. The new device should be installed in the landscaped area at the west side of the building. Perform a detailed camera inspection of the sanitary sewer and storm drain piping to determine the exact condition of piping and required work scope. The pipe sections to be inspected should be selected in consultation with UCD Engineering and BMS. 26

4. Fire Sprinkler System 4.1 Fire Sprinkler System Description Currently there are no fire sprinklers in Upper Freeborn Hall. Lower Freeborn has a standard fire sprinkler system throughout. 4.2 Fire Sprinkler System Condition The existing fire sprinkler system does not comply with NFPA 13/25 and UCD campus standards. The non/conforming items include the type of sprinkler heads and their placement, pipe risers with alarmed checks, seismic restraint at piping system, inspector test and drain risers, and the fire smoke alarm system. 4.3 Recommendations We recommend upgrading the fire sprinkler system to current campus standards. 27

5. Plumbing Systems 5.1 Domestic Water Systems 5.1.1 Domestic Water Systems Description and Condition Refer to the table included in the Site Utilities section for a description of the building domestic water service. Domestic hot water is generated via a storage type, steam to hot water heat exchanger located in Mechanical Room 3. The heat exchanger is original equipment of 1960 vintage, is in poor condition and has far exceeded its economic useful life. The DCW water supply to the heat exchanger is untreated water. Also, there are no tempering/scalding safety controls. The building water distribution piping is copper and appears to be in serviceable condition. The age of the plumbing fixtures located in various restroom clusters varies greatly. Most of them are outdated and worn out, while some are still in serviceable condition. 5.1.2 Domestic Water Systems Recommendations Due to age and condition, the domestic hot water heat exchanger should be replaced. The DCW supply to the heat exchanger should be provided with a non/chemical type water conditioning system (i.e. Scale Blaster). The Heat exchanger controls should have the capability to prevent against scalding conditions. If the restroom remodeling work scope is not extensive, the plumbing fixtures should be surveyed in detail to determine if they can be reused. However, if the restrooms will be extensively remodeled, then new plumbing fixtures should be provided. 5.2 Building Sewer System 5.2.1 Building Sewer System Description and Condition Refer to the table included in the Site Utilities section for a description of the building sanitary sewer service. The building sanitary sewer piping is cast iron and its condition is currently unknown. The BMS personnel have reported that some pipe sections do not drain adequately. A detailed camera inspection should be performed to determine the exact condition of piping and work scope required. A duplex Sanitary Sewer Lift Station (SSLS) is located in the Basement Mechanical Room 3 and collects all drainage from the basement restrooms 28

before pumping it up to the building main sewer system. The SSLS appears to be in serviceable condition and no issues have been reported by the BMS personnel. 5.2.2 Building Sewer System Recommendations Perform a detailed camera inspection of the sanitary sewer main piping to determine its exact condition and work scope required. This should be done by a contractor or consultant with a camera at specific locations to determine the overall system condition. Based on the experience of the campus maintenance personnel it is likely large portions of the system are in too poor of condition to support this facility for the long term. If this is confirmed, we recommended replacing the waste and vent systems in the building with new. Perform a detailed evaluation of the SSLS to determine its condition and work scope required. 5.3 Building Storm Drain System 5.3.1 Building Storm Drain System Description and Condition Refer to the table included in the Site Utilities section for a description of the building storm drain service. The building storm drain piping is cast iron and, while no major problems have been reported, its condition is currently unknown. 5.3.2 Building Storm Drain System Recommendations Perform a detailed camera inspection of the storm drain main piping to determine the exact condition of piping and work scope required. 5.4 Natural Gas Systems 5.4.1 Natural Gas System Description and Recommendations Refer to the table included in the Site Utilities section for a description of the building natural gas service. The natural gas building piping is routed from its point of entry to an Emergency Generator located in an outdoor enclosure at the North/West corner of the building. The gas piping and components are in good condition and no work is required. The generator exhaust system is not low NOx compliant and the exhaust system location does not meet building code requirements. We recommend reviewing the areas of non/compliance with the appropriate Campus department to identify options. 29

The distribution system consists of GSM ductwork located above the Projection Room ceiling, ceiling supply diffusers and return air registers. It operates under stand/alone thermostat control and is not controlled by a Siemens Apogee DDC system. This system is original equipment of 1960s vintage and has far exceeded its economic useful life. However, it still appears to be in serviceable condition. The Multi/zone unit (MZU) has supply and return fans, economizer section with power exhaust into mechanical room, primary filters, heating and cooling coils and four pairs of zone mixing dampers. The distribution system consists of GSM ductwork located above the basement ceiling, ceiling supply diffusers and return air registers. The MZU is controlled by a Siemens Apogee DDC system. This system is original equipment of 1964 vintage and has far exceeded its economic useful life. However, it still appears to be in serviceable condition. The louvers (with backdraft dampers) at the west wall of the mechanical room which are connected to the concrete air/way are intended to relief exhaust air from the Multi/zone unit and AHU/2. 31

These dampers are of 1960 vintage and are not in operable condition. It does not appear they are in serviceable condition. All ductwork insulation is un/faced, 1 thick and either in poor condition or missing. Supply and return main ducts (with the exception of AHU/1 (S1) are of 1960 vintage, government clip and flange or slip and drive type. Joints are in poor condition and leak excessive amounts of air. Duct gauge and stiffening are not per SMACNA recommendations for operating pressures at AHU systems. Sound attenuation intended to muffle dynamic noises from mechanical equipment at mechanical room walls is un/faced 2 thick fiberglass insulation. The insulation is of 1960 vintage, is torn and delaminating in numerous areas and generally in poor condition. There are (1) 5/ton and (1) 3/ton condensing units in Basement Mechanical Room 3.

The FCU has exposed ductwork, a dedicated condensate pump, and is controlled by a stand/alone wall thermostat. The equipment was installed in 2003 and is in good condition. The 3/ton condensing unit is paired with a wall/mounted FCU which serves the Electrical Room. The FCU is controlled by a stand/alone wall thermostat. The Electrical Room is located inside the Basement Mechanical Room 3 at its north end. The 3/ton equipment is about ten years old, is in poor condition and it does not appear to provide adequate cooling. The refrigeration lines are not installed per manufacturer s recommendations. 6.1.2 Air Handling System Recommendations With the exception of AHU/1 which has been recently upgraded, the air handling units serving Freeborn Hall are original equipment of 1960s vintage and have far exceeded their economic useful life. They are not energy efficient and are not able to provide adequate temperature comfort for the various types of spaces they serve. However, mechanically speaking, they still appear to be in serviceable condition. This means that, with proper maintenance, their life could be extended for a few more years, but this should only be considered if the spaces they serve will not be remodeled during the seismic upgrade. The exhaust air backdraft dampers and louvers located at west wall of the air/ way should be replaced with new dampers, louvers and controls. All supply and return air ductwork insulation should be replaced with code/ complying insulation. All supply, return, and outside air ductwork located inside Mechanical Room 3 should be replaced with new ductwork constructed with leak/proof joints, 32

seams, and of SMACNA/ approved construction for the service pressure class. All other ductwork that would become exposed during the remodeling work should be evaluated at that time if it can be reused or replace with new. Since AHU/1 has been recently upgraded it will not require a significant amount of work. We recommend replacing or refurbishing all the dampers and actuators associated with the economizer section because they have not been included in the upgrade work. This includes the outside air, return air and exhaust air dampers. Both condensing units installed in Mechanical Room 3 do not comply with the building code. The 5/ton system is in serviceable condition, but may not be worth saving due to the costs associated with relocating the condensing unit and modifications to comply with the manufacturer s requirements. The 3/ton system is old and not worth keeping. We recommend replacing these with chilled water Fan coil Units. The general recommendation is to replace all air handling systems of 1960s vintage with modern, energy efficient systems. The exact system type and configuration should be determined by the design engineer in consultation with UCD Engineering based on space type and usage requirements. 6.1.3 HVAC Hydronic Systems 6.1.3.1 HVAC Hydronic Systems Description and Condition The building is connected to the campus chilled water system via a set of 6 pipes entering the building through the west wall of the Basement Mechanical Room 3. Water is circulated to the air handlers by a set of constant/volume, base/mounted, end/suction pumps located in the same mechanical room. The pumps are old, in poor condition and have far exceeded their economic useful life. Before the building was connected to the campus chilled water loop, chilled water was provided by steam/powered absorption chiller located in the Basement Mechanical Room 3 and a matching cooling tower located outside at the south/west corner of the building. This equipment, including the steam PRV and chemical treatment have been decommissioned. The chiller has been abandoned in place and the cooling tower removed. The building is also connected to the campus high pressure (150 lbs.) steam system via a set of 4 steam and 2 condensate pipes. The steam pressure is reduced by a single/stage pressure reducing station providing low pressure steam for the building. The low 33

pressure steam serves the hydronic and domestic water heating equipment. The condensate is returned to the campus system by a duplex, electric driven condensate return pump. All of this piping and equipment is located in the Basement Mechanical Room 3. While some of the pressures reducing valves are in serviceable condition, the majorities of steam components are in poor condition and have far exceeded their economic useful life. The hydronic heating system consists of one steam to water, shell and tube heat exchanger, two constant/volume heating hot water pumps and supply and return piping to air handlers and zone reheat cols. The system circulates 140 F to 180 F water throughout the building. The heat exchanger is in poor condition. The pumps are old, in poor condition and have far exceeded their economic useful life. 6.1.4 HVAC Hydronic Systems Recommendations Due to the age, condition and configuration of the equipment and systems, we recommend replacing all chilled water, steam and heating hot water equipment and piping within Mechanical Room 3 with new, efficient equipment configured to match the current campus standards. The controls and CHW building valve, CHW bypass valve and BTU meter could remain and be reused. The abandoned absorption chiller (PIC M03) should be removed and sold for its salvage value. This will free up valuable space in the basement, allow an efficient configuration of the mechanical room equipment and possibly return some space for other usage. 34

7. HVAC Controls System 7.1 Direct Digital Controls System / Description The building HVAC systems are controlled by a campus/standard Siemens Apogee, DDC EMS system which has been installed incrementally over the past several years. This includes controls for the HHW system, CHW system, and all AHUs with the exception of AHU/5. An air compressor located in Mechanical Room 3 provides compressed air for all pneumatic control devices. 7.2 Direct Digital Controls System Condition The DDC EMS system is in serviceable condition. The control/air compressor is in good condition and with proper service could continue to provide reliable service. 7.3 Direct Digital Controls System Recommendations The recommendations for the HVAC Control system depend on the type of work proposed for the HVAC systems. If the existing air handlers are refurbished and continue to be used in their present configuration, then no controls work is required. If new air handling systems will be provided, these would have to be fitted with new controllers which are capable of implementing the latest Campus Standard control strategies including trending and monitoring. The UCD Energy Management Office should be given the opportunity to salvage any controls components installed on equipment planned for demolition. 35

8. Electrical Systems 8.1 Electrical System Description The Freeborn Hall electrical service is fed to the site from the west via the Campus 12.47KV medium voltage distribution system. The existing facility is served via a 500KVA Dry/type transformer located in the electrical vault on the west side of the building. This service transformer was replaced 10 years ago by the Electrical Improvements Project Phase 2B including a 1600A main distribution board (PIC E01) adjacent to the service transformer in the electrical vault to feed existing bus duct serving the existing main switchboard of the building and electrical services to the utility well pump. The system voltage is 120/208Volts. The main switchboard feeds panel PL1A, distribution panel (DA) and motor control center (MCCA). Distribution panel DA feeds Panels SA, 1A, 1B, BA, BB, BC and BD. Panels SA, 1A and 1B are two section panels. The emergency system consists of a natural gas powered generator on the northwest side of the building. Lighting: The lobby area contains several multi pendent lights with combined controls at the front doors. The lighting in the main assembly hall is 2x8 fixtures above panels that have T12 lamps and smaller bug eye type lights underneath. (PIC E02) These primary lights appear to be controlled from an LCP in the back stage area which is fed by panel SA/1 & 2. The basement corridors have 1x4 surface mounted fluorescent lights, the ancillary areas mostly contain 2x4 fixtures some are surface mounted and newer renovations are recessed. The bathrooms and stair wells were upgraded with multilevel LED lights and motion control in the Smart Lighting Initiative project (PIC E03) that was preformed campus wide. Suite 10 has recessed 2x4 fixtures in ACT grid. Suite 5 has 2x4 fluorescent lights that are surface mounted on ACT ceiling. The radio station lighting consists of 1x4 fluorescents, surface mounted on hard lid ceilings. Areas 7 and 6 pendent mounted focal point lights in main areas, sub/offices have 2x2 light fixtures. The Aggie TV area appears to contain primarily 2x4 fluorescent lights that are surface mounted. 8.2 Electrical System Condition The entire electrical system is more than 50 years old which is past its lifetime and no preventive maintenance has been performed on record, physically they appear in good condition considering their age. In 2009 panel PL1A was added feed from the main switchboard. It fed new panel AV and dimming rack #2. Panel BD appears to have a newer section but no date could be confirmed. Panels NPLAB, P and NA1B appear to be added later than 1960 but no hard dates could be found. The generator was installed in 1975 (project #750102), then replaced in 1993 (project #20805) (PIC E04). 36

Lighting: Lobby lights appear to be installed after the original project; however a definitive date was not found. They appear in good condition. Lighting in radio station (suite 14) was reconfigured in 1967. Current Lighting in auditorium was installed in 1987. 1x4 lights in accessible restroom and storage room on first floor replaced in 1996. Suite 10 was renovated in 1996. The lights in room 22 and 22A appear to have been changed in 2002 with 1x4. The production lighting was upgraded in 2009. 8.3 Electrical Recommendations 8.3.1 Provide a new main switchboard, distribution panel boards including feeders, and branch panels. 8.3.2 Provide emergency egress lighting throughout to meet latest code requirements. 8.3.3 Consider providing a lighting control system to minimize energy consumption. 8.3.4 Consider upgrading all lighting to LED standards. 37

9. Telecommunication System 9.1 Telecommunication System Description The main telecom room is shared with electrical. It is located in the basement on the west side of the building. The primary telecom equipment is in this room. The fiber optic boards are also located in the main electrical/telecom room. The primary feeds come from a vault just north of the building. The building distribution consists of several Telecom cabinets, three of which are located in the basement and the other three are on the first floor. There are several WAP placed on the first floor and basement. 9.2 Telecommunication System Condition The incoming outside plant cabling (copper and fiber) are up to date. The main telecom room has inadequate HVAC. Many of the telecom outlets throughout the building are surface mounted and were installed after the original contract. Almost all of the Fiber Outlets are surface mounted. The Network 21 box appears to be in very good condition and relatively new. 9.3 Telecommunication System Recommendations 9.3.1 Provide a separate room with sufficient cooling to be designated as the main telecom room. 9.3.2 Relocate all primary telecom equipment and cabling to the new main telecom room. 38

10. Fire Alarm System 10.1 Fire Alarm System Description The current fire alarm system contains a Silent Knight 5820 panel, power module 5895XL and a voice evacuation system; these are located on the first floor. The remote annunciator panel is located in the lobby near the manager s office. A music relay was installed that overrides the sound system when an alarm is triggered. There are many dedicated speakers for the voice evacuation system throughout the building. The basement overhead doors have dedicated addressable area smoke detectors located adjacent to them. Each of the exits has pull stations, and there is duct detection in the assembly hall. The basement halls and rooms have horn/strobes and area smoke detectors. 10.2 Fire Alarm System Condition The existing fire alarm panel appears to be in good condition. The Fire Alarm renovation project (#842) in 2000 upgraded many of the fire alarm implements. 10.3 Fire Alarm System Recommendations 10.3.1 Upgrade the fire alarm panel to the latest version to accommodate additional device required during renovation. Expander boards and power supplies will be required to add more devices. 10.3.2 If required for freight elevators, provide elevator recall during alarm and re/wire system for all existing devices to send signal to the fire alarm panel. 10.3.3 Provide additional detection and notification devices in areas to be renovated. 10.3.4 Upgrade all smoke detectors located inside AHUs and FCUs. 39

11. ADA Compliance The accessible path of travel and ADA compliance report is done on a set of drawings included here in Appendix D. 12. Hazardous Materials Hazardous material could be part of the renovation project based on what areas are impacted. The current UCD hazardous reports for Freeborn Hall are attached in Appendix E for both asbestos and lead. Before any project begins, all affected areas would need to be tested. All of lower Freeborn has 9 x 9 VAT tile that usually tests positive for asbestos. 13. Acoustical and Production Systems There was an acoustical study done in 2004. The preliminary report dated 07/26/2004 and recommendation dated 09/09/2004 are included in Appendix F. There was also a report dated 10/12/2004 titled Preliminary Recommendations for Audio/Visual System Design at U.C. Davis Freeborn Hall. From these reports a Production System Improvements Master Plan was developed. Attached is the work scope key from that master plan with a check next to the completed items. 40

The Group The Acoustics & Vibration Group 5700 Broadway Sacramento, CA 958201852 916#5?4.444' FAX: 916-457-1475 Consultants tn Acoustics, Vibration & fioise Control Acoustics (The Acoustics & Vibration Group) July 26, 2004 Adam Shalleck The Shalleck Collaborative, Inc. SUBJECT: Preliminary Results of Acoustical Analysis and Evaluation of U. C. Davis Freeborn Hall Dear Adam, This letter documents the initial results of acoustical testing and analysis of Freeborn Hall at U.C. Davis. Freeborn Hall was originally designed to be used as a concert hall for the University=s orchestral group plus for use for conferences and pop concerts. Today it serves as a multipurpose room for lectures, banquets, pop music concerts, and more. The orchestra no longer uses Freeborn Hall for performances, since they have the new Mondavi Center. Changing the main role of Freeborn Hall requires changes to the acoustics and audiovisual system. This process starts by identifying existing acoustical conditions at the site and then doing acoustical modeling of the space. Sound tests were performed on May 28, 2004 at the project site. Tests include measurement of the reverberation times in the hall using impulsive balloon pops and pink noise, background sound level measurements with the HVAC system operating, and sound distribution tests of the installed loudspeaker system. Each of these test types are discussed. Architectural Acoustics The results of balloon pop and pink noise reverberation time tests indicates that while the decay times are closer to ideal for natural music enhancement, they are too high for amplified music, lectures, banquets or dramatic performances. Displayed in Figure 1 is a sample of sound decay test results using balloon pops as the source of sound. The reverberation times varied at each position, although at higher frequencies the variation, was less. Also shown in Figure 1 are the ideal design goals for the new uses of the assembly hall. Both upper and lower goals are used to provide a range of acceptable sound decay times. Again, as apparent in Figure 1, there is not enough absorption in the middle frequencies and too much sound absorption in the upper frequencies above 4000 Hz. During the tests a slap echo was heard between the parallel walls on either side of the front of the stage. A person speaking on stage would likely hear themselves a second time after their initial word is spoken. The side walls at the front of the stage should be redesigned to eliminate the apparent echo. In addition, it is unclear whether the diffusions panels along the sides and rear of the assembly hall are doing much to diffuse the sound. For amplified music and lectures, these panels will not be needed and should be removed as part of the redesign. 17

Ro4i4 2: Shalleck Collaborative, UCD Freeborn Hall, Remedial Acoustic Design, July 26, 2004 frsshb The computer model is showing that insufficient sound is being absorbed on the ceiling. Most of the additional acoustical treatment will be added to the ceiling. The fine print of the PDF drawing file indicates that the perforated board along the side should be pegboard rather than asbestos boards I assume that this is what James Monday found. We will send you additional treatment options later this week. This may include removing the perforated board. Let us know what your thoughts are for treatment that fits with the aesthetics. Mechanical Acoustics Background sound levels of Freeborn Hall were measured with the HVAC system operating. Figure 2 shows the results of background sound measurements at various positions throughout the assembly hall compared to Room Criterion, RC, curves published by the American Society of Heating, Refrigerating, and Air-Conditionirig Engineers (ASHRAE)[i]. Ideally, the sound from the HVAC system in the hall should fall in the range between an RC 25 to 30. Under ideal conditions, this equal an A-weighted sound level of 32 to 37 db(a). Background sound levels currently fall between an RC of 32 to 37 depending on the location with A-weighted levels of 32 to 44 db(a). The highest levels were measured on the main floor on the right side of the room. Higher levels would have been measured if the tests had been done closer to the returns mounted in the side wall between the main floor and mezzanine. While the sound levels are higher than ideal, the background sound at least follows the slope of the RC curves very well. That is, there are no pure tones or substantial peaks or valleys across the frequency range. Further evaluation of the mechanical system is required to provide any recommendations for improvement. Subjective evaluation of the room showed high vibration levels on the stage. As a minimum this would be a distraction for those performing on the stage. The vibration appears to be related to the mechanical equipment. Further analysis is required to find the source and develop a fix. Finding a fix is recommended. Sound Distribution The house sound system was evaluated for frequency response and sound distribution as part of the acoustical tests. Figure 3 gives a set of frequency response curves for the sound reinforcement system. First of all, it is evident in the graph that the system was not properly equalized. There is a substantial dip in the sound levels around 315 Hz at every position. Secondly, the variation in sound levels at the measurement positions is higher than our typical performance specification for sound systems. Sound levels varied by 7 db(a) throughout the seats in the hall. This translates into a distribution of V 3.5 db(a). Ideally, the distribution should be V 2 db(a) or better. As part of our analysis, we are looking at corrections to the sound system. This will be a general overview of what type of system should be installed, where speakers should be placed and what kind of video system will be required. 18

Ro414 2 - Shalleck Collaborative, UCD Freeborn Hall, Remedial Acoustic Design, July 26, 2004 OTOUD Please call if you have any questions regarding these results and comments. Let us know what additional information you need. We have received verbal authorization for doing the sound system, but no mitten confirmation for either proposal. Because of insurance requirements, we need some letter of authorization. I would appreciate it we could receive such a letter. Thanks. Sincerely, Brian R.

Acoustics, Vibration & ttolse Control Adam Shalleck The Shalleck Collaborative, Inc. 203 Randall St. San Francisco, CA 94131 SUBJECT: Recommendations for Architectural Acoustic Treatment of U.C. Davis Freeborn Hall Dear Adam, Documented in this letter report are the results of acoustical modeling and analysis of Freeborn Hall at U.C. Davis. Sound tests were conducted at the end of May in Freeborn Hall to learn the existing acoustical conditions within the space. Results of those tests were presented and discussed in a previous report dated July 26, 2004 [i]\ A computer model was developed for Freeborn Hall and compared with measured results. Once an accurate model was constructed, acoustical treatment was added to the various room surfaces to reduce the reverberation times in octave bands to acceptable levels. As stated in the previous report, insufficient sound is being absorbed by the ceiling. The existing glued-on thin acoustical ceiling tile is inadequate in quantity to absorb enough of the sound energy. Because the ceiling tile is thin without insulation or an airspace behind, the ceiling tile absorption is skewed toward the high frequencies. The side walls appear to have plenty of absorption from the curtain treatment, with the exception of the slap echo between the parallel walls at the front of the stage. Currently, these wall surfaces are covered in wood. paneling. The rear wall has a slat absorber/diffuser tuned to approximately 350 Hz, as calculated from the slat design. Absorption of the rear wall is therefore most prominent in, the 250 and 500 Hz octave bands. Further sound absorption in the current space comes from the upholstered seating, even with the riser-style seating folded down and stacked in the retracted position. Additional acoustical treatment is needed to lower the reverberation times to acceptable levels as shown in Figure 1. Both an upper and lower design goal is given to designate an acceptable range of sound decay times. Two conditions were modeled. One condition leaves the current ceiling system as is except the ceiling tile and angle sound diffusersq would be removed while for the second condition, the ceiling or a false ceiling would be dropped. Ideal for acoustics under the second condition is providing better diffusion using a random a semirandom pattern or a barrel/convex shape from side to side to distribute the sound better. We have not heard back regarding structural limitations or seen any proposals for changes, so have limited ceiling changes to these two conditions. Acoustical treatment of surfaces remains the same for both options. * - Number in brackets refers to references listed at the end of this letter report. 24

R04142.2: Shalleck Collaborative, UCD Freeborn Hall, Remedial Acoustic Design^ September 9,2004 The The side and rear wall reflective panels should be removed to allow more sound to reach the draperies on the side and the wood-slat rear wall.[the rear wall works well at absorbing mid frequencies and does not need to be replaced. If atlifferent look is desired for the rear wall, the slat absorbers can be redesigned or replaced with l-inch. thick fiberglass panels over a hard surface or several other options are available..the ;pegboard can be replaced as it is having no acoustic influence. If sound absorptive material, i.e., regular building insulation were installed behind the peg board, the acoustical value would increase. However, the model is suggesting that additional sound absorption is not needed on this surface. An assumption was made that the number and size of the windows would not change and, therefore, the square footage of drapery would remain the same. The draperies are important to the total sound absorption provided by the sound walls. Thus, if these are to be replaced, the acoustical sound absorption quality of the material is an important issue. This must be part of the criteria for any changes that are made. The stage area has not been completely evaluated, pending proposed changes to this space. The existing ceiling system can be replaced with one that is better for the proposed uses since symphonic groups are not expected to play at Freeborn Hall. Several treatment options were modeled, with most of the treatment on the ceiling surface. Both Two of the treatment possibilities are provided for review, one is a fiberglass panel system and the other is a spray-applied acoustical plaster. Figure 2 displays the effects of the two acoustical treatment options compared with the design goals and current conditions in the hall. The fiberglass panel treatment works a little bit better in that it requires less material and does not have excess absorption at 4000 Hz. Unfaced fiberglass insulation can be substituted for the panels depending on cost or aesthetics. Either acoustical treatment will be a vast improvement to the current design. The square footage of material required for each treatment option is listed below along with acceptable product manufacturers; 1. Option 1: 2" Thick Fiberglass Panels or Exposed Insulation 1. 2 inch cloth or vinyl wrapped or painted fiberglass panels or 2-inch thick insulation with a minimum Noise Reduction Coefficient (NRC) of 0.85 when tested per ASTM C423 using a mounting Type A per ASTM E795. 2. Approximately of 5700 square feet of 2" thick fiberglass panels or insulation should be applied to the underside of the ceiling. 3. Acceptable suppliers - panels, the following or equal: 1. Wall Technologies 2. Conwed 3. Decoustics 4. Lamvin 5. LBI/Boyd 4. Acceptable suppliers - unfaced insulation: 1. Owens Corning 2. Knauf 3. CertainTeed 25

Ro4i4 2 2: Shalleck Collaborative, UCD Freeborn Hall, Remedial Acoustic Design, September 9,2004 5. Aesthetics 1. Panels are either wrapped in breathable cloth, perforated vinyl or painted surface with almost limitless variety of colors and patterns 2. Unfaced insulation that is 2-inches thick would probably be a black duct liner. Cotton is also available as a substitute for fiberglass in a variety of colors 2. Option 2: Spray Applied Acoustical Plaster 1. 1V4 inch thick spray-on acoustical treatment with a minimum NRC of 0.70 when tested per ASTM C423 using a mounting Type A per ASTM E795. 2. Approximately 7200 square feet of 1V4 inch thick spray-on acoustical plaster should be applied to the underside of the ceiling. 3. Acceptable suppliers - spray applied plaster 1. Pyrok 4. Aesthetics 1. A variety of finishes are available including a rough plaster look similar to stucco and a semi-smooth finish 2. Color can be mixed into the product or the product can be painted with up to 4 coats of latex paint without affecting the acoustical properties of the plaster. In addition to the options listed above, absorptive or diffusive products or both should be incorporated on the side walls of the stage to eliminate the slap echo. This can be done with simpler-inch thick cloth wrapped fiberglass panels for absorption, or with specially designed Barrel or random diffusion panels. If you can provide us with proposed changes in the shape and finishes for the room, we can provide additional analysis of the acoustic influences of these changes. The shape and the finishes are both important. We have not done any further analysis of the mechanical system as it was not part of the scope-of-work. Vibration problems on the stage should be addressed along with some of the high sound levels near the return air openings on the main floor. Both the background sound levels and the vibration levels exceed recommendations exceed guidelines published by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) [2]. Let us know if additional information is required to address these issues. Please call if there are any questions or comments regarding the results of this report. We look forward to working with you as this renovation project moves forward. Sincerely, Brian R.

Acoustics, Vibration & Motse Control Audio-Video Systems (The Acoustics & Vibration Group) October 12, 2004 Adam Shalleck The Shalleck Collaborative, Inc. 582 Market St., Suite 2002 San Francisco, CA 94104 SUBJECT: Preliminary Recommendations for Audio-Video System Design at U.C. Davis=s Freeborn Hall Dear Adam, This report documents the preliminary remedial audiovisual system design a:t Freeborn Hall on the U.C. Davis campus. As the needs and uses of Freeborn Hall have changed over the years from an orchestral performance space to an events center, an upgrade to various systems within the hall is needed. After the lighting system has been upgraded, next on the list of items that need modernization is the video presentation system. Once the lighting and video presentation systems have been upgraded, the audio system can receive a makeover. This report is intended to provide an unbiased design and cost estimate for the video and audio system upgrades. Equipment is listed by type without brand names, along with an estimated cost for each item. Existing Systems Currently, the video presentation system is composed of a portable projector and screen that are set up and torn down by support staff after every event. A presenter plugs directly into the stand-mounted projector. The screen is typically positioned at the center of the stage. The video system is currently not integrated into the house audio system. The audio system consists of permanent and portable speakers, amplifiers, processors, microphones, source devices, and a mixing board. Two equipment racks in the control booth house the amplifiers, electronics, and various tape/cd source devices. An assisted listening system exists as well, fed by a microphone at the back of the hall. Main speakers are arranged in left, center, and right clusters above the front of the stage. The speaker system performance, documented in a previous report by TAVG, does not provide even sound coverage throughout the hall. The main speakers are from a company that specializes in guitar amplifiers and other systems meant for individual instruments, and are not ideal for the space to serve as a main reinforcement system. Ancillary speakers for the lobby and control booth are fed by the microphone mounted to the rear wall of the hall, the same microphone used by the assisted listening system. The assisted listening system and the lobby speakers should not be fed by 30

Ro414 2-2: Shalleck Collaborative, UCD Freeborn Hall, Remedial Acoustic Design, September 9, 2004 f this microphone as it results in poor intelligibility through these systems. The position of the microphone results in a large portion of the sound being affected by the reverberant field. Proposed Systems and Components Video Freeborn Hall will accommodate a variety of events ranging from award banquets to touring concerts.. As such, a permanently installed video system needs to be easy to use and setup while providing a high quality picture in varied lighting environments. A mirrored pair of video projectors and screens is proposed for visual presentations. Each screen will be positioned in the stage wing areas so the center of the stage remains clear, hung from above by a new support structure. The screens will be motorized to tuck away when not in use and tensioned to provide a flat surface for showing data and video. Both screens will be a minimum of 10 feet tall by 13 feet 4 inches wide, a 200-inch diagonal viewing area. The projectors will be either based on Liquid Crystal Display (LCD) or Digital Light Processing (DLP) fixed pixel display technologies with a light output of 6000 ANSI lumens or more each. The high brightness will allow images to be clearly visibly on the large screens with normal lighting conditions in the hall. Other features of the projectors include a native SXGA resolution, horizontal and vertical lens shift, network connectivity, and various lens options. The projector will be mounted to a motorized lift to help align the projector with the top of the screen and to allow the projector to retract when not in use. Both the projector lift and electric screens can be raised or lowered with wall-mounted buttons or a key. A matrix switcher/scaler will be at the heart of the video system, allowing up to 8 different sources to be directed to 2 independent outputs scaled to the native resolution of the projectors. Each of the two projectors can show separate sources simultaneously with this device. The matrix switcher also routes the audio corresponding to each of the video sources to the outputs. Source devices include a DVD player, a VHS player, motorized video cameras, a document camera, and two computer connections. The outputs of the matrix will be sent to a distribution amplifier to transmit the video signal over Category 5 or 6 cable. A receiver at each projector separates the data back into computer video signals. Distribution of the video through Cat'5 or 6 cable simplifies the conduit and decreases the cost of cable. In addition, multiple video output locations can be wired with the low cost cable for immediate or future needs. Audio The audio system redesign focuses on improving the signal routing and overall audio quality in Freeborn Hall. Problems such as the poor intelligibility in the assisted listening system need to be addressed. Changes in the audio system need to reflect the new architectural acoustic design of Freeborn Hall. One of the main portions of the audio system that should be changed are the loudspeakers. The loudspeakers should come from a company that manufacturers numerous products for permanently installed sound reinforcement systems such as JBL, Electro-Voice, Renkus-Heinz, EAW, or one of many others. The speaker drivers should be horn-loaded to provide a tighter pattern control, keeping sound where it is needed and away from reflecting surfaces and open microphones. The speakers should be capable of full frequency range sound to handle the various music and speaking formats. 31

R04142.2: Shalleck Collaborative, UCD Freeborn Hall, Remedial Acoustic Design, September 9,2004 A Digital Signal Processing (DSP) based audio signal routing system is proposed for the hall. The DSP unit-not only handles most of the signal routing, but also replaces equalizers, crossovers, limiters, and any other processors in the equipment rack. One set of mixing board sends can be input into the DSP and routed to not only the amplifiers and on to the loudspeakers, but also to ancillary speakers and the assisted listening system. A direct output from the mixing board will solve the intelligibility issues with these systems. The basic DSP unit is an 8-input and 8-output module, expandable by adding additional modules. Another feature of the DSP is that it clan store scene@ settings recalled at the touch of a button depending on the type of event at the hall. A simple three-button programmable control panel with an LCD screen can be remote mounted in a one-gang wall box in multiple locations within the hall. The control panel is programmed to control any of the DSP parameters including volume level and scene recalls. One other item that the staff of Freeborn Hall wants to see added is a new 24 channel analog mixing board. The microphones probably do not need replacement, although a new wireless system and accessories could be added to the existing system. To power the new loudspeakers, the existing amplifiers may need to be supplemented with additional amplifier units. Other Equipment A floor-standing equipment rack will be needed to house the new audio and video components. The equipment rack will be positioned in the control room adjacent to the existing racks. A new power sequencing system is recommended to turn on and off all equipment. Currently, staff must follow a set procedure for turning on each piece of equipment manually. With an automatic sequencing system, the operator initiates the on@ command with a button or key and the equipment powers on in a predetermined sequence with adjustable delay between sequences. A rack-mount sequencer and remote sequencers at the projectors will be required. On the electrical side, it is recommended that all of the existing and future audio/video equipment be powered by circuits on an independent 10-circuit technical power isolated ground panel. The panel should be on an isolation transformer sized per the equipment load to prevent drawing from other building systems and to reduce noise. The equipment racks will need 3 or 4 20-amp circuits, with an additional 20-amp circuit at the mixing board location in the control room. A 20-amp circuit should also be used for the video projectors. Another 20- amp circuit should be used for the mixing location on the assembly hall floor, and at least a pair of a/v 20-amp circuits should be used for the stage area. Cost A cost analysis is provided at the end of this report. The estimate shows the main components broken out and a price associated with each item. Specific brands and models are not listed. Only list prices are given, actual street prices vary from product to product and will be less than the prices shown. The highest cost item for the video system is the projector. Projectors that meet the design criteria vary greatly in list price, ranging from $20,000 to more than $50,000 per projector. Typically, the higher cost projectors will produce better quality images, but this is not always the case. For this application, we feel that anything much more than $35,000 list price per projector and lens is not worth the additional cost Many other 32

R04142.2: Shalleck Collaborative, UCD Freeborn Hall, Remedial Acoustic Design, September 9, 2004 products in the a/v system vary greatly in price from manufacturer to manufacturer as well, although not typically as drastically as the projectors. An estimate for labor, installation, and programming is also included. Costs associated with the electrical infrastructure changes recommended for the a/v system is not included and should be sought from an electrical contractor based on our recommendations. An estimate of the projector screen support structure is not included as well. Please call if there are any questions or comments regarding the audio-visual system design presented in this report. Although this is a preliminary system design, we would be happy to develop a more detailed design as this renovation project moves forward. Sincerely, Brian R.
