Modelling for construction, interpretation and coordination.
Modelling to interpret IFC drawings and to aid coordination prior to construction is the ‘fruit that hangs’ even lower than clash detection:
I have been thinking since yesterday if I should pre-empt likely comments on my column post – or column-column and explain myself further...(I can also call it a column on the post too if we assumed that columns and posts were interchangeable in construction jargon as well as journalism...)
Or should I just move onto something more exciting, getting a bit flat here?
Apologies for being a bit of a broken record – but there is really no way forward for BIM (I believe) until the need for basic modelling in construction is eliminated, i.e. there is a meaningful design model in existence and available to contractors prior or at least at the start of construction.
A digital model that is capable of replacing or at least being totally in sync with IFC drawings
(IFC = Issue For Construction).
Currently (often) GCs foot the bill for construction modelling and it is a costly exercise.
The major factor of cost is not what is being modelled but how many drawings and other documents need to be found, opened, interpreted for a competent modeller to be able to model it;
Hard to call this BIM, really – building owners please, demand pre-construction, digital design models from your consultants!
