A 12,500 seat, 405,000 sq ft sports and entertainment facility is designed to replicate the aura and intimacy of "Mac Court" in a modern and sustainable form. The LEED Gold-targeted building includes two practice courts, a weight room, training and nutrition facilities, ticket offices and two retail Duck Stores.

The Mechanical system includes VAV Air Handlers with associated FCU's and VAV's, along with Constant Volume AHU's. The four large Bowl AHU's had Sensible Heat Wheels along with hot water heat. Heating water came from the campus loop system through a large Heat Exchanger with 3 large base mounted pumps. The Chilled water also came from the campus loop system through a large CHW heat exchanger to isolate the pressures of the campus loop from the building system along with 3 large base mounted pumps.

The Plumbing system has a large domestic water booster pump with re-circ pumps located around the building. 3 large heating water generators are located on the concourse level. There are multiple sump pumps and 4 large sewage ejector pumps on the project. The project has large public bathrooms on the concourse and upper concourse levels totaling 195 water closets and 93 wall mounted lavs.

The North Tower Addition in 1984 was the beginning of our relationship with the hospital. Other projects have included extensive remodels within the existing hospital, parking structures, boiler room additions and the construction of the new Center for Outpatient Services (COPS). Some work has been done on a Design/Build basis.

These projects included;

- Steam piping systems
- Medical gas piping
- Hydronic chilled and heating water systems
- Duriron acid waste and vent systems
- Fuseal acid waste and vent systems
- Compressed air and vacuum systems
- Surgical rooms

Our foreman, Jerry Moore received a craftsmanship award from the Salem Contractors Exchange for his work on the COPS Building.




Salem Conference Center   Salem , OR

Project Type   
 Multi-Use Building
General Contractor   
 Rushforth Construction
Mechanical Contract   
 $2,900,000.00

The Salem Conference Center Project utilized state of the art Mechanical and HVAC systems including;

An in-floor radiant heating and cooling system. The in-floor system is used to supplement the heating system in the winter and then automatically switch over and provide supplementary cooling system in the summer. This is one of the first projects on the west coast to utilize an in-floor system for both heating and cooling. The in-floor system required that over 30,000 feet of flexible plastic pipe be placed below the rebar and cast into the concrete floor with no joints made in the pipe in the concrete.

A large air to air Energy Recovery Unit, which utilizes a refrigeration cycle with no moving parts.

The use of natural ventilation and shading; The HVAC control system utilizes information from an onsite weather station to open and close operable windows and shades based on ambient conditions such temperature, wind direction and speed and solar radiation gain.

Two first generation chillers, which utilize frictionless magnetic bearings to reduce noise and vibration while increasing efficiency.

At almost 270,000 square feet this project required two chillers, four boilers, and thirteen large air handlers. The mechanical system included a four pipe heating and cooling system and extensive science lab systems. Once all slabs were completed it took only 14 months to complete the project. Extensive coordination drawings were a large part of the early completion.

The greenhouse environments in this facility are control by a sophisticated computerized control system that includes dedicated air handlers and chiller, a shading system, vent system, unit heaters, exhaust fans and a fogging system.




State of Oregon - North Mall Office Building   Salem , OR

Project Type   
 Office Building
General Contractor   
 LCG Pence Construction
Mechanical Contract   
 $2,363,000.00

Two modular boilers provide hot water heat that is distributed by circulating pumps to air-handling unit coils and perimeter fin-pipe radiators. An underfloor air distribution system delivers tempered air to each workstation via manually operated floor diffusers. The atrium/lobby doubles as a passively conditioned connector and natural stack ventilator. The atrium setpoint temperature range was expanded to reduce mechanical HVAC needs. The atrium is heated by exhaust air and direct solar gain on exposed concrete floors and walls, supplemented by perimeter radiant hot-water heaters when needed.

From the Statesman Journal
September 7, 2007

When Josh Welborn went into his senior year at Sprague High School in 1987, he figured the team would need some kind of a miracle to be competitive. It showed up in the form of new head coach Robin Hill. In Hill's first year, the team went from winning one game to reaching the state playoffs. When the Sprague Booster Club approached Welborn, the owner of Oregon Cascade Plumbing and Heating, 20 years later, to donate his company's time and resources to building a new FieldTurf gridiron for Sprague, Welborn said yes. "He came along his very first year and turned everything around," Welborn said. "Back then, football was my life. My brother, it was his life. I just wanted to give back." Wednesday night, he and some of his six employees who played football for Hill at Sprague came out to eat a burger and marvel at the new surface the team will be playing on.

They'll be back tonight when Sprague debuts the field as the Olympians play McMinnville at 7 p.m. "We feel real fortunate that we've able to get the field done in a tight time frame," said Bill McNutt, past president of the boosters. "We felt fortunate that the school district had confidence in us to let us give it a try because this was the first in Salem-Keizer."

The fundraising started last spring and brought in more than $900,000 in cash and in-kind donations.Tonight will be the payout. "It's a big project," said Chris Roche, the fundraiser on the installation. Quot;The biggest hurdles related to the fact that it hadn't been done before on a private-public partnership. If we hadn't had the support of the district, whose been great.
