BIM protocol
It is not the role of this book to set out Building Information Modelling (BIM)
processes and procedures in detail, but it is important to recognise the growing
importance of BIM in the construction industry, the importance of BIM as an
influence on the Plan of Work 2013, and the broad activities that are required
during the project process if BIM processes are followed. Evolving BIM technology
is transforming modes of working in the construction industry in terms of
how design data is generated, shared and integrated, which in turn creates a
requirement for new protocols, activities and definitions.
Varying levels of ‘maturity’ of BIM use have been defined. Level 0 BIM is the use of
2D CAD files for Technical Design. Level 1 BIM acknowledges the increased use of
both 2D and 3D information on projects and embraces the need for management
processes to sit alongside design processes. Level 2 BIM requires the production
of 3D information models by all key members of the design team, although not
necessarily using a single project model. Level 3, or iBIM, involves collaborative
use of a single, interoperable digital model by all members of the design team
simultaneously.
The book has set out certain key actions that need to be carried out for projects
where BIM is to be used at Level 2 and above, which require certain protocols to
be followed, including appointing a project information manager and preparing
a project BIM Execution Plan as part of the Project Execution Plan.
Information manager
The information manager has the responsibility of developing, implementing
and updating the BIM Execution Plan; taking a lead in the planning, set-up
and maintenance of the model and leading the design team with regard to
development of the design model and the protocols used.
BIM Execution Plan
This document should set out: the parameters of the project; project team
members; the BIM standards to be used; the deliverables from the model; the
software to be used; the data exchange method; the file naming convention;
a schedule of quality control checks; and a schedule of dates for review of the
model by the design team.
Level of detail
Although CAD information is produced ‘full size’, when drawing are issued,
whether as hard copy or electronically, the level of detail added to the drawing
is dictated by the scale of the output. BIM changes this approach as such outputs
