term expectations of their buildings. Taking a complete system approach to rainscreen support provides greater and more readily available technical insight and data, reducing the risk of incorrect specifi- cation or product substitution.
Speeding up the specification process through electronic data
Having clear visibility on the technical data at the design and specification stage to use in BIM is crucial too and this exists in different forms:
RECOMMENDED
Every type of roofing and cladding panel has recommended fasteners to attach it to the structure
Having clear visibility on the technical data at the design and specification stage to use in BIM is crucial too
1. BIM structured product data Structured product data sheets for BIM are available for fasteners which present product information in plain language with simple questions and answers allowing integration into a greater system element, be that data or 3D geometry. They standardise data to enable the comparison and selection of products based on value and life cycle benefits rather than just price.
2. BIM objects
For rainscreen support systems, specifiers can benefit from equally comprehensive information in the form of BIM objects.
These allow for the creation of digital representations of the intended layout together with detailed technical information, accreditations and other background data to provide a relevant information-rich support specification.
3. Bespoke software solutions Unique software solutions provide project-specific cladding solutions to meet precise requirements. After submitting information online, specifiers receive electronic data such as project-specific bracket and rail spacings, guide pricing per m² and a prefilled NBS specification document, with an option to access thermal calculations based on the unique wall build-up configuration.
Higher quality fastening systems and new technology to aid the design and specification of the building envelope is a positive step forward. Switching to more advanced solutions often requires small additional capital expenditure, but signifi- cant savings in operational expenditure can be achieved.
