Why is it included in the project?
The rainwater management design determines how rainfall will be handled. A roof system can be one part of the selected approach. To understand the requirement for a particular roof, the project design and specification need to be reviewed.
What does passive mean here?
The water-retaining approach relies on the material and layer build-up rather than commands from a connected controller. The required build-up and performance data must be identified for the particular system and project.
When should we talk?
Early coordination helps account for area, heights, access and interfaces before other rooftop equipment is installed. If construction is already approaching, start with the specification and roof plan you have.
What needs to be coordinated?
The rainwater requirements, available area, permitted loads, waterproofing, drainage outlets, other rooftop systems and access during installation and later use.
Product data and system data
A board is one component. The installed system includes a specific build-up and installation detail. A component test result should not be treated as the performance of the complete installed system.
Preparing an enquiry
A roof plan, rainwater management requirement or specification can help us understand the project. An initial question is also enough to start the conversation.
