Over the coming weeks we will look at several scenarios relating to the Design and Building Practitioners Regulation implementation which are likely to be reflected in real world jobs.
Consider the following;
The project is a Mixed-use building (with Class 2);
a) Building work all approved and underway
b) S4.55 modification for the addition of 1 apartment, or other change, soon to be issued, IE after 1 July 2021
c) The Construction Certificate (CC) application for the S4.55 modification is post 1 Jul 2021
It is clear that the work to be approved by the new CC needs a Design Compliance Declaration, but how far does the declaration need to go?
Let’s look at this example:
Part of the new works to the Mixed-use building (with Class 2) will be a modification for the sprinkler system design, to capture the new apartment, amongst other changes.
The sprinkler design for the new apartment is captured, however, to declare that the new piece of work complies, it is my interpretation of the regulations that the entire sprinkler system needs to be looked at from the point of the new work, all the way back to the street connection.
The new part of the sprinkler system cannot be compliant if some part(s) of the entire system supporting that new part is not compliant.
This will potentially affect every part of the building. Not just relating to fire safety, but from structure, to weatherproofing, to drainage systems, etc. as the Design Compliance Declaration needs to cover the new work and anything supporting it.
Whatever the scenario, Credwell can assist with finding the path to compliance and achieving a Design Compliance Declaration and/or a Building Compliance Declaration.
