#RESIDENTIAL FIRE SPRINKLER SYSTEM DESIGN GARAGE INSTALL#
This will also drive up labor costs with the added time to install and trim out the extra sprinkler heads and the larger pipe which is heavy and increasingly difficult to work with. While the material costs of the sprinkler heads might not be as significant in the big picture, it does mean that the pipes feeding the sprinkler heads will need to be larger to meet water flow and pressure requirements, thus driving up costs. These classifications are important because they dictate how close the sprinkler systems need to be, along with the amount of water that will be demanded. The higher classifications, ordinary group 2, and extra hazard groups 1 and 2 are the next levels of hazard in fire ratings, each one is the next step based on the amounts of heat that could potentially be given off in the given area. An example of an ordinary hazard group 1 includes restaurant serving areas, bakeries, and car parking areas. Ordinary hazard group 1 is for areas where materials combustibility is low, but the measure of combustibles is moderate. The next level of occupancy is an ordinary hazard that is broke down into two groups. Light hazard, the least restrictive occupancy rating is used for buildings with conditions like churches, schools, and offices. NFPA 13 has different occupancy classifications based on the measure and combustibility of the materials that are in the protected space.

This code gives guidelines for the spacing of sprinklers and how much water they must provide to the building. The code that dictates the installation and design of sprinklers is the National Fire Protection Association 13 (NFPA 13).

To understand why mixed-use buildings are potentially problematic, it is first important to understand the basics of how to design a sprinkler system for buildings. The other option is to use code 302.3.3 by separating the different classifications with fire separations so that different parts of the building are designed like they are separate buildings. A fire separation is a wall or floor which is designed to stop the spread of fire to adjacent spaces for a certain period allowing occupants to escape to safety. The building does not need any added fire separations except where they are specified elsewhere. The code allows the spaces to individually categorized themselves by the level of hazards and then the entire building is designed based on the most restrictive provisions. The International Building Code (IBC) gives many guidelines for mixed occupancy buildings in section 302.3. The spaces with different uses may need different sprinkler types and spacing based on occupancy.

Mixed-use buildings have special challenges for the design of an automatic sprinkler system. Even many small towns have an old main street building that is restored to have a business at street level with apartments above. Many downtown metro areas have mixed-use buildings, which serve more than one purpose - such as a building with a parking garage in the basement, a retail or restaurant on the ground level, and apartments or offices on the upper floors. This article will cover mixed-use building sprinkler requirements and how to effectively design a building so that it meets fire code but is also cost-effective. An important part of safety equipment is the automatic sprinkler system in buildings, which may be a small part of the budget, but if it is not accounted for, could result in significant costs. This added challenge can result in costs being much higher to design and build the building. Because of this, many buildings are built for more than one purpose, making them non-traditional when it comes to design.
