CPD 7 RAINWATER OUTLET DESIGN AND SPECIFICATION

摘要

Efficient water management is critical to the longevity of a building. Rainfall onto flat roofs needs to be correctly managed to protect the structure against ingress of water, but the consideration and design of rainwater outlets is often left too late in the design process. It is common practice to defer it to the roofing contractor to address at a far later stage of the specification. This CPD shows how the choice and specification of the roof structure and its finishes can make a significant impact on the capacity required for surface water drainage.
