09A1L - Multi-Building Exterior Window Repair and Replacement ($895,000): This project removes old sealants, cleans and primes joints, and re-applies sealants in the building envelope, including inbetween areas of the face brick, at aluminum frames, and at operable windows This project will address the sealant joints in the tower portion of the building only, which will require swing-stage access from the roof Interior finishes will be patched and repainted as required Significant areas of existing sealant joints have failed on the exterior of the Educational Sciences Building, a 13-story building with face brick skin Chronic leaks have caused damage to the building envelope and interior surfaces Significant areas of existing sealant joints have failed on the exterior of Van Hise Hall, a 15-story building with brick and precast concrete skin Chronic leaks have caused damage to the building envelope and interior surfaces UW-Madison continues to address building occupants’ indoor air quality concerns due to water leakage OSH - 09D2G - Halsey Science Lecture Hall HVAC Replacement ($765,000): This project replaces three air handling units, and associated controls and ductwork that serve three lecture halls to achieve functional, operational, and energy efficiency improvements Project work will primarily be limited to mechanical rooms and includes replacing air handling units, return fans, ductwork, and temperature controls The air handling systems included in this project provide conditioned air to the three large lecture halls which seat 108-211 students The majority of introductory science classes are held in these rooms, which are heavily utilized throughout the academic year The 45year-old air handling units were not replaced during the 2001 renovation to the Halsey Science Center The units are old, worn out, and inefficient The facilities maintenance staff has responded to numerous complaints about the air quality, quantity, and comfort levels in these lecture halls that are directly related inadequate performance PKS - 08L2Q - Multi-Building Restroom Renovations ($2,427,900): This project renovates 30 restrooms in buildings (~4,826 SF) to repair failed plumbing systems and fixtures, and to meet current building code and ADA standards Restrooms will be expanded as required to meet the current building code and ADA standards, and where possible, to meet current standards for fixture count Project work includes demolition of existing fixtures, floors, wall finishes and ceilings; installation of new tile floors, drywall and tile walls and drywall ceilings; installation of new fixtures, toilet partitions, lavatories and restroom accessories; and installation of new associated steam domestic water heaters The mechanical, electrical, and plumbing systems will be completely renovated in the restroom areas All architectural finishes in project areas will be replaced Where possible, sustainable design features will be utilized such as automatic faucets, dual flush low flow toilets and urinals, occupancy sensors, high efficiency light fixtures, and fixtures and accessories made with recycled materials The restroom configurations and infrastructure are original to building construction, between 1969 and 1973 Most of the existing facilities are not ADA compliant The plumbing systems have failed frequently, in particular the cast iron drains and galvanized supply piping The plumbing fixtures are deteriorated and broken The electrical and mechanical systems not meet current code requirements The architectural finishes are also failing, especially the ceramic tile surfaces The current fixture count in specific locations is not sufficient to serve building use Health, Safety, and Environmental Protection LAX - 09D2F - Multi-Building Fire Alarm System Replacement ($876,900): This project replaces the fire alarm systems in Cleary Alumni Center, Morris Hall, and Murphy Library (236,957 GSF) to improve smoke and heat detection, provide additional audio/visual alarm signals to meet ADA code, and improve maintenance The replacement will ensure greater security for building contents and improved occupant life safety The new fire alarm systems will be of a fully addressable type with one way voice capability A new annunciator panel, new pull stations, new heat and smoke detectors, and new speaker/strobe signal devices will be installed per current applicable codes, including ADA The new fire alarm panels will be connected to the campus central fire alarm reporting network which reports alarm and trouble signals to the campus security office The Morris Hall and Murphy Library fire alarm systems were installed in 1989 The Murphy Library system was expanded in 1995 as part of a library addition Subsequent to the addition project, the main fire alarm panel was replaced with a zoned non-addressable system, but the remainder of the system is original Both of these systems are zoned nonaddressable systems, are several generations old, and are no longer supported by the manufacturers Both systems are obsolete, parts are no longer available, and the manufacturing vendor factory support has been absent for several years The systems are not compliant with current building codes, fire codes, or ADA guidelines The fire alarm system problems are occurring with increasing frequency, and the inability to obtain parts makes it difficult to correct system problems in a timely fashion Campus staff has been able to continually repair the systems using salvaged parts from fire alarm systems that were recently replaced The increased downtime trend for the systems has raised concern regarding the possibility of wholesale system failures The Cleary Center fire alarm system was installed when the building was constructed in 1994 It is a zoned, non-addressable, and obsolete system The frequency of system problems has increased and repair parts are difficult to obtain Preventive Maintenance MIL - 08L1Y - Downer Buildings Exterior Envelope Repair ($4,979,000): This project restores the exterior envelope integrity on buildings within the Downer campus historic district (Garland Hall, Greene Hall, Holton Hall, Johnston Hall, Merrill Hall, and Pearse Hall), replaces or repairs deteriorated components, and increases the energy efficiency of the exterior envelope Project work includes sandstone repair and replacement, terra cotta ornamental repair and replacement, masonry tuckpointing and replacement, masonry cleaning and waterproofing, exterior door and window sealant replacement, and masonry paver unit replacement The project scope of sandstone and terra cotta components is limited to those areas which are weathered and worn Previous repair work that is still sound and weather tight, but which does not match the historical character of these buildings, is not included The Downer campus buildings all exceed the age of 100 years require historic preservation work for the exterior envelope Environmental conditions have caused erosion and delamination and require replacing the stone with new material The project scope was developed and determined through comprehensive on-site inspections Programmatic Remodeling and Renovation MSN - 08A2I - University Houses Preschool Renovation ($800,000 increase for a total project cost of $1,600,000): This request increases the project budget to match current design consultant estimates The recent cost estimates significantly exceed the authorized budget and this project budget increase is required to bid the project The project budget increase is needed to complete the originally approved project scope and intent, and to increase the scope to meet current building codes Additional project scope items include construction of a new passenger elevator, separation of mechanical utilities and services, and modification of site access and the associated roadwork OSH - 09C1H - Dempsey Hall Restroom Renovation ($1,354,688): This project renovates approximately restrooms and replaces galvanized and cast iron piping throughout Dempsey Hall Project work includes renovating male/female restroom groups; creating accessible restrooms on the first floor, and replacing selected electric water coolers with new units near the restrooms Janitor closets and pipe chases will be reconstructed to accommodate the rest room space modifications The spaces will be modified to meet current use and ADA requirements This project replaces the cold and hot water recirculation domestic water piping, which is galvanized with copper piping, and installs new insulation and shut off, isolation, and mixing valves The water service from the building to the street will be replaced with appropriately sized piping The cast iron sanitary system will be replaced to include a new connection to the sanitary system at the street The electric water heaters will be replaced with new energy efficient steam to water heat exchanger units to supply hot water New plumbing fixtures, toilet partitions, and accessories will also be installed These modifications will require upgrades of the room finishes, electrical, and HVAC systems to facilitate the work described above The asbestos materials will also be abated as part of a separate contract while the piping is being modified Dempsey Hall is the second oldest academic facility on campus Galvanized pipe was used for the domestic water supply lines – cold, hot, and hot water re-circulating, in both the 1918 and 1969 portions of the building These lines have failed numerous times, and as a result contain many patches Deposits, reducing water pressure in the building, are clogging the lines The domestic water supply to the building is undersized and inadequate to serve the building The building sanitary sewer lines leak and clog frequently, creating maintenance issues The three electric hot water heaters are old and inefficient A replacement steamto-hot water converter will be more energy efficient The public toilet room facilities in the building will be renovated to address backlog maintenance items, gender access issues, and ADA accessibility The men’s and women’s facilities are not uniformly located on all floors, making it difficult to access appropriate facilities The 2nd floor has two separate single-stall women’s toilet rooms, which are inadequate for the ratio of building occupants One of these single-stall rooms is located within an office suite, which makes access by other women in the building even more difficult The population of this building is approximately 80-85% women An appropriate sized women’s toilet room is needed on 2nd floor STP - 09C1I - Multi-Building Restroom Renovation ($3,442,200): This project renovates approximately thirty-six (36) restrooms and eight (8) showers in Collins Classroom Center, Communications Arts Center, Health Enhancement Center, and the Learning Resource Center The spaces will be modified to meet current use and ADA requirements provide new plumbing fixtures and associated piping, modify the plumbing supply, sanitary and vent systems, and provide associated room finishes and electrical modifications to facilitate the work described above The exhaust system will be revised due to its age and increased requirements The asbestos materials will be abated as part of a separate contract while the piping is modified Project work includes the following: Collins Classroom Center Renovate male/female restroom groups; create an accessible unisex restroom on the first floor, and create a high/low electric water cooler grouping near the restrooms Communications Arts Center Renovate male/female restroom groups to create accessible restrooms on each floor that are stacked to take advantage of plumbing piping efficiencies and replace the existing electric water coolers near the restrooms Health Enhancement Center Renovate male and female restroom/shower groups, male/female restroom groups and replace the existing galvanized piping through out the Berg and Quandt sections of the facility The showers, water heater, and storage tank will be replaced New shut off, isolation, and shower tempering valves will be provided to accommodation future connections to a thermal solar pool heater system Due to the removal of the existing piping, many ceilings and walls will require repair and/or replacement of the room finishes as well as modification to the adjacent electrical and HVAC systems Learning Resource Center Renovate male/female restroom groups and create a high/low electric water cooler grouping near the restrooms Most plumbing fixtures and room finishes are original to the facilities, Communications Arts constructed in 1928, Collins Classroom Center in 1966, the Learning Resource Center in 1970, and the Health Enhancement Center - Berg section in 1952 Temporary measures have been taken to minimize the leaks yet some cannot be specifically located, or patched, or repaired without partial demolition of interior partitions throughout the floor levels Plumbing chases are either non-existent or not easily accessible, and the sanitary waste piping cannot be replaced unless the existing plumbing fixtures are removed Floor urinals drains are beginning to leak and water stops are in disrepair and in some cases not hold Any and all galvanized piping within the buildings will be removed and replaced with copper Restroom fixture count does not reflect current gender mix of Communications Arts building occupants The classrooms in the three buildings have benefited from the many State Classroom Project and Lab Modification funds over the year yet the restrooms have gone untouched as these monies are not allotted to repair or replace them Utilities Repair and Renovation MSN - 09B2R - Pit 18/10 to 31/10 Steam and Condensate Repairs ($650,000): This project will replace box conduit from Pit 1/10 to 26/10, which is from Holt Commons east along Kronshage Drive, and then north on Babcock Drive to the northwest corner of the Agricultural Bulletin Building The compressed air, steam, and condensate lines will be replaced with larger sized pipes to bring all fittings up to a minimum of Class 150 rating MSN - 09A1P - Walnut Street Heating Plant Switchgear/Transformer Installation ($644,000): This project installs a medium voltage switch, feeder, third transformer Select loads (approximately 35%) from the existing switchboard to the new switchboard will be re-routed to reduce the existing loading to a safe, stand alone condition Load demands on the two switchboards have exceeded each of their individual current capacity limits The 480-volt tie switch has needed to be closed to supply enough current to the growing number of circuit loads Closing of this tie switch parallels the two existing transformers and has essentially doubled the available fault current at each feeder breaker Except for the two main breakers, no feeder breaker is rated to be able to withstand a solid bolted fault on its load side This operating condition creates a potentially severe safety concern and is considered a noncompliant code issue If a fault situation would arise, it would disable the plant for an indeterminate amount of time 9 PKS - 09C4Q - Campus Primary Voltage Conversion ($2,572,300): This project converts the primary electric distribution voltage from 8,320-volt to 12,470-volt The 30KV incoming switchgear line-up will be replaced with a new 25KV metal enclosed switchgear The 10 MVA, 24.9KV/8.32KV transformer will be replaced with two 5/7 MVA, 24.9KV/12.47 KV transformers The 8KV distribution switchgear will be replaced with a new 12.47KV sheltered aisle switchgear The equipment will be located in the switchgear yard located just north of the Heating and Chilling Plant The 8KV capacitor bank in the switchgear yard will be replaced with a 24.9KV capacitor bank The campus substation was constructed in 1972 There have been no substantial modifications since construction In 2002, the transformer tap was changed to accommodate a Wisconsin Electric Power Company (WEPCO) regional distribution voltage change from 26.4KV to 24.9KV The switchgear equipment is over 30 years old and is reaching the end of its useful life The medium voltage cabling between the campus substation and the building service transformers was replaced under State Project No 94114 New cable was 15KV rated to allow future conversion to 12,470V service WEPCO is eliminating its 8KV distribution voltage from its service areas As this process proceeds the utility will retain less 8KV equipment for temporary service in the case of transformer failure This is a problem in the case of a campus building transformer failure The utility will have less equipment available to help us on a temporary basis We may need to find a transformer from an electrical supplier that stocks replacement transformers This can also be a problem since the availability of 8KV replacement transformers is decreasing due to the elimination of 8KV distribution on a national level This problem was evident when a 2000 KVA transformer failed recently at the Heating and Chilling Plant A replacement 8KV/480V transformer could not be found so WEPCO installed a 25KV/480V temporary pad mounted transformer until a replacement could be manufactured The temporary transformer was in place for an extended period of time until the new transformer was installed It was fortunate that a 25KV WEPCO overhead service line was located in the vicinity of the plant An alternate service line source is not available for most campus buildings WTW - 09C4P - Campus Substation Switchgear/Transformer Replacement ($3,554,600): This project replaces the 25KV outdoor overhead structured substation, two MVA oil filled transformers, and the indoor 5KV circuit breaker distribution lineups with new modern equipment to improve the electrical distribution system reliability, redundancy, and capacity to serve future campus loads The project also installs new cable and pad mounted switches to provide redundant loop feeder distribution to existing radial circuits in the north-west and north-east portions of the campus The campus electrical service consists of two MVA, 13.8-4.16 KV power transformers connected to two line-ups of metal clad switchgear Each transformer is connected to one line-up with a buss tie connection between the lineups One transformer and associated switchgear lineup is over 40 years old The other transformer and associated lineup is over 35 years old This equipment is beyond its useful life and repair parts are becoming difficult to obtain Oil samples were recently taken from both power transformers for analysis The test results indicated an elevated level of hydrogen gas in the north 10 transformer This may be an early indication that this transformer is beginning to fail The current campus demand load of 5,125 KVA exceeds the capacity of one power transformer It is anticipated that the demand will increase by approximately 1,800 KVA with the operation of a new 1400 Ton campus chiller, the construction of a new 217,000 GSF business school and the construction of a new 160,000 GSF residence hall If one transformer were to fail during a period of high demand, the campus would need to reduce load to avoid over loading the operating unit WTW - 09C1O - East Residence Halls Steam Distribution Renovation ($250,000): This project replaces approximately 525 LF of 10-inch steam and 5-inch condensate piping enclosed in a concrete box conduit with new steam and condensate piping within a new concrete box conduit on the east side of Prairie Street between Steam Pit 33 and Steam Pit 36 Project work includes excavation and removal of steam and condensate pipe, asbestos abatement of pipe insulation, repair and reconstruction of concrete box conduit as necessary, installation and insulation of new piping, enclosing and waterproofing the box conduit, and restoration of the site, including restoration of concrete sidewalks and curb and gutter disturbed by excavation for this project The steam and condensate lines in this area and the steam pits to which they connect were installed in 1966 to serve Knilans, Tutt, Wellers, and Wells Halls Approximately 300 LF of the piping is located below a service drive The steam and condensate lines are encased in a concrete box conduit below the service drive where it is suspected that salt infiltration has deteriorated the condensate piping Condensate piping under roadways and sidewalks is susceptible to corrosion due to de-icing salt leaching into the soil In 2003 the condensate line from Steam Pit 32 to Steam Pit 33, in this area, was found to have corroded so badly that sections of the condensate piping were gone entirely In the late 1980’s the condensate line from Steam Pit 34 to Steam Pit 35 was sleeved with stainless steel piping (approximately 115 LF) because of corrosion and consequent leakage This reduced capacity to Tutt Hall, Wellers Hall, and Wells Hall Justification of the Request: UW System Administration and the Division of State Facilities continue to work with each institution to develop a comprehensive campus physical development plan, including infrastructure maintenance planning After a thorough review and consideration of approximately 450 All Agency Project proposals and over 4,500 infrastructure planning issues submitted, and the UW All Agency Projects Program funding targets set by the Division of State Facilities (DSF), this request represents high priority University of Wisconsin System infrastructure maintenance, repair, renovation, and upgrade needs This request focuses on existing facilities and utilities, targets the known maintenance needs, and addresses outstanding health and safety issues Where possible, similar work throughout a single facility or across multiple facilities has been combined into a single request to provide more efficient project management and project execution 11 Budget: GFSB – Facilities Maintenance and Repair [Z060] .$ 4,604,300 GFSB – Health, Safety, and Environmental Protection [Z100] 876,900 GFSB – Utilities Repair and Renovation [Z080] 5,436,100 GFSB – Programmatic Remodeling and Renovation [Z065] 4,796,888 GFSB – Special and Movable Equipment [Z051] GFSB – Preventive Maintenance [Z350] 4,979,000 GFSB – UW Infrastructure Maintenance [Z450] 2,427,900 PRSB – Facilities Maintenance and Repair [T550] PRSB – Health, Safety, and Environmental Protection [T560] 10 PRSB – Utilities Repair and Renovation [T570] 11 PRSB – Energy Conservation [WS10] 2,339,300 12 Program Revenue Cash [AGFU] 2,234,800 13 Program Revenue Cash [AGF0] 14 Gifts/Grants Funding 800,000 15 Building Trust Funds [BTF] Total Requested Budget $ 28,495,188 Previous Action: 02/20/2008 MSN -
