Mumford & Wood sash window

Mumford & Wood product library

Mumford & Wood, the manufacturer of timber windows and doors, has announced compliance with NBS National Building Information Modelling (BIM) Library Data for core Conservation entrance, balcony, bi-folding, single and French doorsets as well as Conservation casement windows, box sash and spring sash windows.

This is in accordance with the Government’s mandate on all publically-funded new-build projects by spring 2016. Architects, specifiers and contractors can now visit the company’s technical page at and download the full Mumford & Wood NBS BIM Library Data.

In this 3D modelling of the company’s core and standard Conservation products detailed specification parameters are shared in relation to thermal performance and U-values, acoustic specifications, PAS24 compliance, product design details, paint, glass and warranties.  Non-standard products can be analysed on request using the same criteria.

“Now all parties, manufacturers, architects and contractors will pool this design information to create the footprint of a building,” says Owen Dare, technical director, Mumford & Wood. “This will effectively lock the specification which will remain unchanged for the life of the building.  It is quite a complex and very sophisticated platform but the benefits are huge.  Once approved, the specification will be carried through to manufacturing making the whole process easier for everyone.”

BIM Level 2 approval

Mumford & Wood has achieved BIM Level 2 approval. At this level the product data using 3D CAD models enables contractors and architects to combine and share their own 3D models, for a specific project, to a minimum Industry Foundation Classification (IFC) or COBie (Construction Operations Building Information Exchange) standard. It is available in a common file format, either an IFC or more probably a Revit plug-in. The core of Level 2 BIM is to provide accessible, up to date, accurate, verified information for use and re-use for all projects.

Asset management and asset construction both need an information management system and process, support by a number of tools to manage data. The data can then be used through many activates to realise and add value.

Level 2 BIM components are information management, classification, digital planning of work and information exchange method COBie. There are many other benefits that will make designing a project with reduced risk and cost which allows management of the building to be controlled through the life cycle of the building.
