Caroline Hall and Motherhouse Renovation

We converted the 1950’s-era Caroline Hall (32,000 SF) to a dormitory style residence and installed all new central HVAC, plumbing and electrical systems. The work at the historic 1890’s Motherhouse building (200,000 SF) consisted primarily of upgrades to HVAC, plumbing and electrical systems, providing a new electrical service and central air conditioning.

In addition, the campus utility systems had been modified and renovated in various methods over the campus’ history, and there were virtually no existing drawings. Using our skills in fieldwork and investigative analysis, we were able to accurately document the existing systems and make sure the affected systems were addressed appropriately. It was important to us and the owner that there was no loss of utility support to the surrounding buildings. We were very successful at upgrading the systems in these buildings through three phases, without interruption to the surrounding buildings.

Liberty High School

Wentzville School District – Wentzville, Missouri

A New 227,055 square foot high school facility with a master plan of 285,000 square feet.  Athletic fields included tennis courts, baseball field, softball field, football field with track and grandstand, concessions facility, restroom facility, and practice fields. The project included an irrigation well and irrigation for athletic fields and practice fields covering approximately 6 acres.  The design included several innovative energy efficient elements such as high efficiency restroom fixtures, high efficiency domestic water heaters, energy recover and occupancy lighting sensors. Total project construction cost was $40,323,100 (excludes separate site development project cost). Project received a Cuivre River Electric Cooperative Rebate of $30,000 in 2013.

Pattonville High School Classroom Renovations

Pattonville School District – St. Louis, Missouri

A $3.5 Million project which included a 90,000 square foot renovation of existing classroom wings, offices, and locker rooms over two summers.  Renovations consisted of replacing the existing ceiling grid system, lights, and diffusers with new duct branches. The fire sprinkler heads were also relocated as required.  One wing received a new VRF system with fan coil units and a 100% OA unit with energy recovery wheel serving air independently of the VRF system to the rooms.  Large structural beams in the classroom ceiling limited us to a VRF design. New secondary heating hot water pumps were installed and rebalanced after the deletion of the fan coil units serving this space. The locker room’s diffusers were replaced and new plumbing fixtures were installed to meet ADA requirements.

Mascoutah High School

Mascoutah Community Unit School District #19 – Mascoutah, Illinois

A new 250,000 square foot high school was built in Mascoutah, IL which opened in 2010.  The building consisted of classrooms, two gymnasiums, an auditorium, kitchen, and a wood and metals shop.  The building was cooled by a 960-ton water-cooled chiller plant.  Heat was provided by five condensing hot water boilers.  The building was served by a mixture of variable volume terminal reheat air handling units as well as a handful of single-zone variable volume units serving some of the larger spaces.  Several measures were taken to improve energy efficiency of this building beyond what was required by current energy codes.

Hillsboro Junior High School HVAC Renovation

Hillsboro R-3 School District- Hillsboro, Missouri

A renovation of the entire school’s existing HVAC system. This included the replacement and consolidation of rooftop units, ductwork replacement and modifications, the addition of variable air volume terminal units, and installation of a new centrally monitored automated building temperature control system.  The original electric heating equipment was replaced with gas service, high-efficiency condensing boilers, and associated piping for hydronic heating. The renovation also included the replacement of all the light fixtures, the entire fire alarm system, and modifications to the electrical power distribution system.

Edgewood Children’s Center
