Olin Residence Hall, at Washington University in St. Louis’ School of Medicine Campus, an eleven story high rise building constructed in 1954, was originally a Class III standpipe system with a fire pump but was not sprinklered. McClure designed a wet pipe sprinkler system for the residence floors that included a prefabricated metal soffit to conceal the piping with the exposed structure construction. A replacement fire pump, and fire pump controller connected to a standby generator was designed to replace the original system with an electrical tap ahead of the building main breaker. A new Class I standpipe with valves located within the exit stairwell for fire personal safety was designed to replace the original standpipe that was located in the building corridors.
The first challenge faced by McClure Engineering was the schedule – to provide project documents for rough-in and cabling prior to issuing full bid specifications, before the scope of work was fully determined. Additional challenges were:
- Delivering a control room package that allowed ten of the larger classrooms to be controlled remotely, while having the capability in the future to bring systems on-line from three additional buildings.
- Designing audio-visual systems that were easy to operate for the faculty and staff, but included enough sophistication that allowed the systems to be driven by a technician in a control room located in another building.
- Providing a large number of small systems with automated switching and power “on/off” based on room occupancy conserving energy.
- System needed to support real-time simulcasting between spaces within the facility or between local and remote endpoints.
McClure is currently facing the ongoing challenge of passing real-time large channel count audio between networks. Current hardware is able to switch and/or cascade audio between hardware devices in the control room. However, ideally the control room will be able to accept multi-channel audio packets from different networks, mix, switch and process as required, and then send audio back (between networks).
The control room included a modular switching frame that allows the real-time routing audio and video to pass from local room to control room and back over the campus fiber infrastructure. As additional buildings come on line in the future, fiber cards will be added along with additional control “pods” or stations with supporting electronics where audio-visual or “AV” technicians can jump in and control any room.
Each local system had a dedicated AMX control system processor to manage and integrate communication between all the local equipment, as well as to provide a very user-friendly control interface. Another AMX control system installed in the control room functioned as the “master” controller, sending commands directly to local room equipment when the system was be driven from the control room.
Local small systems included a small form factor controller which was programmed to receive state changes from the rooms occupancy sensor, turning off the local monitor on or off. The system was also set up to pole the AV receiver for the presence of an active input signal, allowing the system to be automatically switched between active inputs, or send a command back to the display to revert back to and show the local PC.
Because the system incorporated a very low-latency fiber optic matrix switcher along with state-of-the-art conferencing codecs, real-time simulcasting and/or video and teleconferencing calls are supported between multiple rooms, or between local rooms and far-end points (such as China). Events can also be recorded and streamed later over the university network or internet.
McClure worked closely with the university, AV Integrator, and the electrical contractor to keep the project on schedule through constant communication with all parties.
The University’s new indoor natatorium was designed as an attachment to its existing Show-Me Center and student recreation center addition. The plans for this state-of-the-art facility provided for: a leisure pool complete with a rock climbing wall built right in; a zip line; a whirl pool; a 6-lane, 25-yard lap pool; wet classrooms; and locker rooms. From the pool observation area, an 80-foot radius infinity-edge pool offers a waterfall effect, spilling over and down the rock wall into the leisure pool. The natatorium was designed to use the existing steam and chilled water utilities, as well as backup systems to help maintain the constant demand.
McClure leveraged the power of the campus utilities’ central steam and chilled water plant to heat and cool the new Aquatics Center. During utility outages at the central utility plant, backup cooling and heating systems maintain the Aquatic Center’s temperature and humidity with a water-cooled chiller. The chiller is piped to use “space reheating” demand for condenser water cooling. However, this energy recovery operation functions in parallel with a dry cooler (used to supplement condenser water cooling) when there is little or no reheating demand. Air is supplied to the natatorium at both the floor and overhead levels. The floor-level supply is ducted through underground fiberglass ductwork while supply air grilles in the top of the bench provide top-down ventilation. Pressure control between the Aquatics center and the remainder of the facility keep the Aquatics center slightly negative to the rest of the facility to maximize year-round comfort.
This project is a complete renovation of an early 1900’s, full masonry structure, to a modern academic building designed to last another 100 years. The building will be comprised mostly of offices and classrooms. We are providing mechanical, electrical, plumbing, fire protection, and audio-visual design services.
The owner desires to achieve LEED certification under the US Green Building Council LEED Rating System. Therefore, we are providing LEED consulting services related to energy modeling, and enhanced building commissioning. The goal of commissioning is to, in a timely delivery, ensure the successful design, installation, and performance of the proposed system.
The new $10M, 59,500 SF facility includes a 2,100 square foot multi-purpose room, a 3,000 square foot academic support center, 3 computer labs, 2 interactive classrooms, 17 classrooms equipped with advance computer and audio/video technology equipment, a cyber cafe and an outdoor patio.
The building systems were designed for energy efficiency. A dedicated outdoor air unit provides ventilation air to the building, using an energy recovery wheel to reduce the required equipment capacity and reduce the operating costs of providing ventilation air. Common spaces utilize carbon dioxide sensors to reduce ventilation air requirements when the spaces are not used and increase ventilation when spaces are occupied, thus reducing energy usage. The systems are controlled by a complete energy management system for off-site control and performance tracking. The classrooms have indirect light fixtures, which provide more diffused light to the space and a more comfortable lighting design.
The site selected was challenging from a construction and acoustical perspective, with the building located just 20 feet from an active commuter train line, and in the flight path of commercial air traffic to St. Louis Lambert International Airport. In addition, the central plant that serves the building is located on the opposite side of the commuter train tracks.
The $52M, 123,000 SF state-of-the-art performing arts facility includes a 1,625-seat performance hall with orchestra pit (the only performance space of its size in St. Louis), a 300-seat theater, 15 dressing rooms, and a 2,300 square foot rehearsal room. Close cooperation with the acoustical consultant was required to design HVAC systems to meet the strict acoustical requirements. An under-floor distribution system was designed for the performance theater due to its large volume, and floor-to-roof height of 60 feet.
The $40M renovation and addition to the existing student athletic and fitness center (totaling 293,000 SF) included two new natatoriums, 50-meter competition pool and diving complex, indoor and outdoor leisure pool areas, cardiofitness area, 42-foot climbing wall, racquetball and squash courts, and a 2,000 ton chilled water plant.
Due to the owner’s desire for minimal downtime for the existing facility, our planning and foresight was essential to the development of a feasible plan for phasing the construction work. Special attention had to be paid to the routing of all utilities in the early phases, so that there would be no re-working of the utilities during the later phases. We were also able to eliminate antiquated building systems during the project, which provided the owner with additional benefits in reduced maintenance costs for maintaining old equipment.

University of Pennsylvania – Philadelphia, Pennsylvania
This project included renovation of two floors and a balcony. Modernizing this 100 year old historic building posed many challenges. The first floor consisted of a classroom, bathroom, electrical/AV room and mechanical room. The second floor consisted of a speaking hall with a stage, green room and event room for catering. The 8,000 cfm AHU in the mechanical room served both floors and additional provisions were made to serve the balcony by a future AHU in the Labs/Classroom Phase. The chilled water, heating hot water for VAV reheat, and glycol heating hot water for the AHU preheat coil were all roughed-in in the Phase 1 project. A high-end AV system was also installed.
Southern Illinois University – Edwardsville, Illinois
The project consisted of an addition of 50,000 sq. ft. as well as a renovation of the existing Art and Design building. The building housed numerous art studios including ceramics, metals, painting, textiles, printmaking, and a foundry. These spaces required a variety of specialty exhaust hoods in in order to meet the studios’ needs. Each art studio was provided with its own single-zone variable volume air handling unit which was used to both contain odors and fumes inside the space as well as provide the proper amount of makeup air for the exhaust needs of the space. Both the new addition and existing building were re-fed with chilled water from a campus loop. Heat was provided by a new condensing hot water boiler plant located inside the building.
