One way to understand your impact on the overall performance of the system is to be involved in the design stages of smoke control systems and to flag an issue when you feel a change will affect that design. Knowing that your discipline can impact the performance of a smoke control system becomes more important as the design of a building is being finalized.
Such features can be affected by the architectural design or the interior design. These may include the location of walls, soffits, draft curtains, and openings in walls and floors. However, architectural features impact smoke control systems as well. They include mechanical and electrical systems, such as fan systems, dampers, ductwork, controls, and monitoring systems. Many disciplines influence smoke control systems. Proper coordination among members of the design team is crucial to ensure that design changes do not impact the smoke control system design. These changes can occur during the design and construction phases. But sometimes changes are made to the building design that are not carried forward to all disciplines involved in the smoke control system design. Hopefully, any inconsistencies in the smoke control system design are identified during the design process. Performance criteria are set early in the design phase so other disciplines can work toward providing design documents that conform to these performance criteria. Many of these pertain to coordination during design and construction as wholesale changes late in construction are not feasible.ĭepending upon the size of the project, the design concepts for smoke control systems often are completed several years prior to final occupancy. The following sections address ways to limit the impact of smoke control system operations. Can changes be made to the approved design criteria to match the installed system, or will wholesale changes be required?
Minor adjustments can be made in the field, but major changes are often impractical this late in construction. What happens next often is based on how far apart the operation of the installed system is from the approved design criteria.
