Lincoln Surgical Hospital Surgery Center Addition

Lincoln, Nebraska

Geary Engineering Inc. provided the mechanical, electrical and fire protection engineering services for the addition to the Lincoln Surgical Hospital. The addition connected the existing hospital building to the adjoining medical office building. Three additional operating rooms were added to bring the total to eight operating rooms. The addition totals of 31,000 square feet on four different levels. Renovations were also made in the hospital and office building where the addition connected to the existing buildings.

Geary Engineering, Inc. has been involved with the design of this project since 1992 when the original 28,000 square foot medical clinic was built. A surgery addition with three additional operating rooms was added in 1997. The medical office building completed in 1998 connected the hospital to the medical office building.

The basement level provides a new entrance to the hospital and has admissions and waiting areas for patients and families. There is also a large meeting room used for training and for patient education. The operating rooms on the first level are state of the art, using the latest technology for OR equipment and monitoring systems. The patient rooms are located on the second level. The sub-basement is used for central supply and mechanical equipment.

Site utilities needed to be relocated before the latest addition could be started. The water service, sanitary sewer, fire main, storm sewer, telephone and main electrical services were all relocated.

The plumbing design included domestic hot, cold and tempered water systems. New water heaters for the increased load were provided. Hydronic piping systems included hot and chilled water to the air handling units serving the operating rooms. The closed loop heat pump system, which was part of the original HVAC system was extended to serve new heat pumps in the addition.

The HVAC systems for the addition included constant volume air handling units to provide the specific air flows and humidity control required for the operating rooms. A chilled water system was designed to provide the cooling to the ORs. The chilled water system also provides a back up to the closed loop heat pump system.

A building energy management system provides control for all of the mechanical systems in the building. All new HVAC equipment and the major equipment in the existing building are all connected to this new control system. Information for the building controls is available on the LAN and is accessible to any work station or off site through an Internet connection.

A new electrical service for the addition was required. Due to the size of the building and the size of the electrical service, a second electrical service was necessary. Emergency power is provided by a 400 KVA diesel generator, sized for the entire building, including the medical office building. Three existing engine generators were replaced with the new system. Emergency electrical systems providing power to the life safety branch, critical branch and essential equipment required their own transfer switches and distribution panels. A portion of the existing hospital was rewired to separate the life safety and critical branches.

Security systems designed for the building included a perimeter detection and access control system. The access control system is computer-based and secures the perimeter after hours and will record the person who gains access to the building. Strategically placed cameras are located to monitor access to the building and to monitor secure areas within the building. All video is recorded and is monitored through a local network and off site through an Internet connection.
