Are pipe schedule systems commonly used in new construction?

Pipe schedule systems are not commonly used in new construction projects today, particularly because they have largely been replaced by more flexible and efficient design approaches, such as hydraulic calculations that take into account the specific requirements of the installed system. While pipe schedules were once prevalent, modern methods allow for more precise sizing and ensure that water delivery is both effective and efficient.

In contemporary fire protection design, systems are usually tailored to the building’s unique layout, height, and occupancy type, which leads to a better overall use of materials and a more effective system. This move away from standardization makes pipe schedule systems less relevant in new construction.

The other statements about the use of pipe schedule systems in specific types of buildings do not hold true as they imply limitations that do not align with current practices. Both residential and commercial buildings benefit from customized design approaches that are more appropriate for today's code requirements and safety standards.
