What needs to be agreed before SIP manufacture starts?
A frozen design package, full construction drawings and system information must be agreed before manufacture begins. Engineered line and point loads and preliminary drawings are issued for review and approval prior to production.
Upon receipt of your frozen design package, we review the content to ensure it matches our scope of supply and estimate documents, at which point our design team commences work on the project.
Drawings required are typically Building Regulations standard or construction issue in both PDF and DWG formats, including:
-
Plans showing full build-ups and SIP positioning
-
Sections showing full build-ups and SIP positioning
-
Build-up details and specifications
-
Information on utilised systems such as MVHR, underfloor heating and Solar, including locations, weights and specifications
This information allows us to accurately set design parameters and value engineer the project by allowing for the loadings required.
The first issue of design coordination is the engineered line and point loads, which must be issued to your structural engineer and catered for within the foundation and substructure arrangement.
Once line and point loads are completed, we apply these to our initial designs and issue preliminary drawings (P1) for review, comment and approval.
Each document is reviewed individually and marked for comment, amendment or approval using status A, B or C.
