SCOPE OF SERVICES
Casne Engineering, Inc. provided the electrical power and lighting design and construction services for the new 100,000 square foot Dempsey Indoor Practice Facility for the University of Washington Athletic Department. The new practice facility features a full-sized football field with a four-lane running track; all enclosed in an air-conditioned roofed structure.

The primary service is supplied by a 480V outdoor unit substation, which is served by the 13.8kV loop campus distribution system. The unit substations provides the facility through a 1000A, 480V main distribution panel board, which through the electrical distribution system, provides 480/277V and 208/120V power for lighting, HVAC, netting motors, and power boxes at four locations for food vendors, and other ancillary loads.

We provided the infrastructure, including conduit, outlets, and communications room layouts, to support all the Audio/Visual systems and telecommunications needs. Casne Engineering also provided the fire alarm system design. The fire alarm system is a stand-alone addressable panel with a communications link to the campus-wide system. Activation of alarm is by automatic sprinklers and manual pull stations. Occupant notification is by means of a pre-recorded voice announcement and ADA-approved strobe lights.

The lighting was designed to allow athletes and coaches to see comfortably and accurately. This was accomplished with a combination of direct and indirect metal halide downlights complimented by a 6,000 square foot clerestory. Emergency egress lighting was accomplished with "instant-on" quartz lights, which in the event of a power outage are powered by a dedicated 60kW generator set to start immediately upon inception of an outage and light the entire space within ten seconds. All lighting is controlled through a low voltage switch control panel and color-coded legend map. The lighting system is very functional, versatile, and easy to operate.

Casne Engineering provided the electrical design as prime consultant for the replacement of the fire alarm and detection system for the Mechanical Engineering Building and Mechanical Engineering Annex at the University of Washington. The system consisted of an addressable control panel with voice capability, peripheral devices such as speaker/strobe appliances, manual pull stations, smoke detectors, duct detectors and door holders. An audibility test was performed during the design phase to ensure minimum audibility levels in all spaces.

Casne Engineering also designed a 40-ton, air-cooled chiller to replace the existing water-cooled chiller, and a new structural platform to support the new chiller. The electrical design included battery-pack emergency lighting throughout the building.

Built at the beginning of the 19th century, two Seattle libraries were listed as historic preservation sites and required renovation. The project involved a full examination of existing service equipment, existing lighting and power distribution. New raceways were installed to accommodate computer terminal power and data requirements. The West Seattle Library required a handicap ramp with recessed pathway lighting. University Library required the installation of a handicap elevator and surveillance camera system. Both libraries required fire alarm system upgrades.

This project involved a 10,000 square foot subterranean biology building with 10 large pyramid shaped glass skylights for daylighting the trees in the main corridor. Metal halide lighting worked with daylighting through time clocks and photocells. Special lighting controls were installed for growing vegetation. Concealed perimeter lighting was used in the main corridor to emphasize daylighting. This project also included an 18,000 square foot underground biology building with a complete power and lighting system, fire alarm, and communication systems.

Casne Engineering provided the electrical engineering consulting services on Allen Creek Elementary School, a new facility located on the west side of Marysville, Washington. The school is 45,000 square feet consisting of 22 classrooms, media center, gymnasium and administrative offices. The electrical design included interior and exterior lighting; power; fire alarm and detection systems; and premise wiring systems for computer and telephone, intercom, clock, and programming systems. The design included a 100kVA/80kW diesel generator for essential power requirements.

Casne Engineering designed the power distribution upgrades required to provide dedicated computer receptacles, panel boards, transformers, and all other associated power distribution equipment. This work required extensive field investigations to document existing field conditions, close coordination with school district personnel, authorities having jurisdiction, and the local utility company. The work included developing plans, cost estimated, and specifications. During the construction phase of the project, Casne Engineering provided construction assistance to the contractor and school district project manager. Tasks included writing change orders and addenda, answering RFI’s, reviewing submittals, answering contractor questions, attending meetings, taking meeting minutes, and providing punchlist data.
