Transcription

1 MUKWONAGO SCHOOL DISTRICT ARCHITECTURE PARK VIEW MIDDLE SCHOOL The original school building was dedicated in 1954 as the High School, with an addition in 1959, a library addition in 1970, and an addition/renovation in The 1993 addition demolished the 1970 library addition as part of the renovation. The building currently contains approximately 114,000 gross square feet on the first floor, with a partial basement area of nearly 5,900 gross square feet. The exterior walls of the 1954 and 1959 buildings are load bearing masonry walls, while the 1993 buildings are load bearing masonry cavity walls. There appears to be no air space or insulation between the brick and block of the 1950 s era buildings. The roof structure for all of the additions consists of steel joist, metal deck, and a built-up roofing system. 1.

8 ELECTRICAL PARK VIEW MIDDLE SCHOOL ELECTRICAL SERVICE AND DISTRIBUTION The main electric service is 3000A, 120/208V 3-phase, 4-wire. The GE Spectra Series service entrance switchboard appears to have about half of its useful life remaining. The main service should be able to accommodate any lighting, bleacher, boiler and circulation pump, water heater, and elevator replacements that have been identified. 1.1 Minor power distribution modifications will be required for bleacher replacement. 1.2 Minor power distribution modifications will be required for (3) boiler and circulation pumps replacement. 1.3 Minor power distribution modifications will be required for (2) water heater replacement. 1.4 Minor power distribution modifications will be required for elevator replacement. SURGE SUPPRESSION The main service does have a TVSS unit to provide surge suppression. EMERGENCY GENERATOR AND TRANSFER SWITCH The emergency generator is a Kohler 135kW diesel set. It is located outside near the utility transformer with an above ground diesel storage tank. One 600A transfer switch that serves both the life-safety and non-life safety loads. This violates current Code, but this installation is grandfathered in so separating the loads is not required unless a new generator is installed. The generator and transfer switch both appear to have about half of their useful life remaining. They also appear to be in good operating condition. LIGHTING The majority of the lighting is T8 fluorescent. Typical classrooms have 2 x4 3-lamp acrylic lenses troffers on 8 x10 centers. 1.5 Corridors have 1 x4 2-lamp acrylic lenses troffers on 10 centers. Some corridors have 2-lamp 18 DTT compact fluorescent fixtures as well. Building staff indicated the desire to relight these corridors to provide better lighting. Exterior lighting is HPS.

9 ELECTRICAL FIRE ALARM The existing fire alarm system in this building is an addressable Simplex 4100 type which was recently installed and can be assumed to comply with the current Code. 1.6 The only work which may be required if a new elevator is installed, is minor modifications for elevator recall. CLOCK SYSTEM A new Primex wireless clock system was installed in No work required. INTERCOM SYSTEM There is a Simplex intercom system with speakers in corridors, classrooms, and offices. It appears to be in good operating condition. Building staff has requested that volume control be provided for the speakers. There are two options for providing volume control on the existing system. They are as follows: DATA DISTRIBUTION 1.7 Option A: Provide attenuator at punchdown blocks in intercom rack. This would allow a one-time volume control adjustment, not daily adjustments. Estimate includes 75 rooms. $4,000 Option B: Provide volume control at individual rooms. This would allow volume adjustment at any time. However, pulling new cable from each room requiring volume control would likely be necessary. Estimate includes 75 rooms. $8,000 The data distribution was completed in the late 1990 s as part of the TEACH telecommunication systems program. Cat 5 outlets are provided in each classroom. TELEPHONE DISTRIBUTION The telephone distribution was completed in the late 1990 s as part of the TEACH telecommunication systems program. Cat 5 phone outlets are provided in each classroom. TELEVISION DISTRIBUTION The television distribution was completed in the late 1990 s as part of the TEACH telecommunication systems program. Television distribution outlets are provided in each classroom. PRA Project No Park View Middle School Page 9
