ABSTRACT

BIM has both advantages and disadvantages to an aluminium systems supplier but the
risk of not adopting the technology far outweighs the disadvantages. BIM is a powerful
tool and can create real value to the industry during the design of a project; however for
this value to be fully extracted, better guidance needs to be given to the suppliers in the
construction chain on how to deliver high quality content. The technology is successfully
forcing collaboration and ownership during design, manufacturing, installing, maintaining
and dismantling of a project, but BIM is only as good as the information fed into the model
from the beginning.
A new work methodology, or set of guidelines, needs to be produced to supplement
existing standards. These guidelines can be used by the aluminium system suppliers to
ensure that the product models they produce are presented and formatted in a
standardised manner. This means that the maximum benefit will be gained from their use
during the design process predominantly, but also in further stages of construction.
These guidelines developed as part of this dissertation give aluminium system suppliers
clear instructions on naming conventions, level of detail and visual content, supporting
parameters, model sizes, and distribution of the content. The guidelines cover the entire
product ranges of all aluminium system suppliers, and give design guides to generate 3D
BIM product models for windows, doors, curtain walling, framing, brise soleil and rain
screen. The guidelines produced in this dissertation are to be seen as creating an
acceptable level of competence within BIM for content creation.
If an aluminium system supplier was in a position to offer all of its product range in BIM
models from using these guidelines then they would have a real competitive advantage
when it comes to getting specified on future BIM projects.

ACKNOWLEDGEMENTS

I would like to express my thanks to both Kawneer UK and Wintech for allowing me the
opportunity to undertake this MSc Facade Engineering Degree, and the support they have
provided me throughout my study.
I would like to thank Dr Steve Lo for providing advice, comments and thoughts on the
further development of the project.
Finally I would like to thank my family, friends and Lauren for their motivation during the
long hours spent preparing this dissertation.
