Fire Sprinkler Systems

Wet and Dry Pipe

Lakeview Building

Viking worked to complete the Lakeview Building, a four-story, 73,000 square foot medical facility located at 1001 East Superior Street, Duluth, Minnesota.

The Lakeview Building includes a cancer care center, infectious disease level, outpatient services, and an internal medicine floor.

Viking was in charge of designing and installing wet and dry pipe automatic fire sprinkler systems in the Lakeview Building.

The wet pipe fire sprinkler system protects all four levels. Each level has its own floor control valve assembly connected to a vertical standpipe, located on the stair landings. This allows individual draining, testing and monitoring. The system also has a hose valve at each level for Fire Department use.The system is supplied by a central valve assembly, located in the basement mechanical room.

A dry pipe fire sprinkler system is one in which pipes are filled with pressurized air or nitrogen, rather than water. It provides protection in spaces where freezing is possible. This system is used to protect the area below the attached drive-thru canopy and the unheated basement level parking ramp. Both areas are supplied by a dry pipe riser located in the basement mechanical room.

In order to maintain a smooth ceiling appearance semi recessed sprinklers were used in the suspended ceiling areas. Fully concealed sprinklers with a flush cover were used in the drywall ceiling areas and soffits.

The coordination of the systems began during the budgeting phase of the project. This resulted in the most efficient use of materials and labor.

Viking shared CAD drawings with The Jamar Company thru APi's network. This allowed them to closely coordinate space requirements and locations of piping runs within the ceiling plenums. Working with APi Electric, Viking was able to coordinate the automatic sprinkler system with electrical and fire alarm wiring interfaces.
