Tempe Municipal District Complex

Project Description: Midstate Mechanical was selected with D.L. Withers for the Tempe Municipal Complex. Midstate’s roll included performing the central plant upgrade for the sensitive, high security Tempe Municipal Complex.

The project scope called for removing and replacing the cooling towers, pumps and chillers. Temporary chillers were utilized to keep the 911 call center on-line which also houses the City’s computer system and various other buildings including in use courtrooms. Considerable coordination and extensive preplanning occurred to keep the building functioning. Crews worked in the occupied building while adjusting schedules to accommodate court sessions, judges and the moving of inmates.

The entire project was completed without affecting the daily operation of the building. Effective communication was paramount to the success of this project. Midstate worked closely with the owner and contractor, communicating daily.

Scottsdale Fire Station

Project Description: The $4 million project includes 12,372 square foot of space for the Scottsdale Fire Station #602, the first Green station for the City of Scottsdale. The environmentally friendly building has many unique features including a cooling tower designed inside a bell type structure of block with a fan and high pressure misting system. This system will remove heat from the beams and blow it down to heat the bay areas.

The mechanical systems were designed with energy efficiency and minimal impact to the environment as highest goals. The HVAC system includes a DX split system AC with a solar heating hot water system. The Demand Ventilation system incorporates CO2 sensors and individual zone temperature control. In addition, ozone friendly 410 refrigerants that are free of ozone depleting chlorine molecules were utilized.

The cooling tower and HVAC equipment are designed to operate at extremely high efficiency levels day and night since the fire station is operational 24/7. The individual zones allow temperatures to vary during demand-based times. Renewable energy strategies such as solar panels were incorporated to reduce energy use and advanced electronic monitoring of the building system ensures peak performance while decreasing consumption.

The goal for the project was to recycle as much as possible of the construction waste. 75% of the construction waste produced was recycled for other uses, never reaching our landfills. Gray water tanks are used to collect water from the sinks and shower drains to be reused for water outside vegetation.

Maricopa County Human Services Campus

Project Description: The Maricopa Country Human Services Campus project was so far over budget that Midstate Mechanical was called on to redesign the entire mechanical system. With Midstate’s expertise in design/build, the project was completely redesigned saving the County $300,000. The campus provides shelter and services for the homeless, including many children. The campus consists of three (3) one-story buildings covering 135,000 square foot. These buildings are for Central Arizona Shelter, Healthcare for the Homeless and St. Vincent de Paul. The $1.7 million (mechanical) scope of the project included the installation of an air cooled chilled water system utilizing both constant and variable volume air handlers, split systems, and evaporative coolers.
