a mature design methodology in the building and manufacturing industries. The
application of BIM is rapidly accelerating as owners and engineering service
providers are increasingly recognising the benefits of the intelligent data
that can be used within 3D modelling.
product, this is not necessarily true. It is a process and a way to manage information
efficiently. It is a way for information to be collated, shared and stored
using 3D modeling, this information becomes intelligent data which can be used
to consult, design, build and maintain assets.
– dynamic engines help define relationships between
objects and keep changes consistent and coordinated
- Knowledge based – can
be constrained by things like regional design codes and criteria as well as company
- Scalable – able to
aggregate huge amounts of data from multiple sources
- Visual – enable better
analysis, simulation and communication
The benefits of BIM are being recognised globally as
governing bodies are beginning to implement regulations and standards to
encourage the use of BIM on building and civil infrastructure projects.
are a lot of factors that are incorporated during the progression of the
project. Such as:
conditions – ground surveys, utilities and services, geotechnical
investigations, property surveys.
– watersheds, drainage, structural, utilities, estimates, traffic, sight lines,
– NZTA, Austroads, regional authorities, company, drainage, lighting, etc.
& Consultation – multiple concept designs.
– 3D design model and calculations
– materials, time management, staging, quantities, etc.
Control – reports, drawings, revisions, etc.
– on-site changes, as-built surveys, etc.
– asset management.
especially when clients, consultants and contractors are in different offices
or on site. BIM is designed to make these factors manageable and collaboration
becomes a constant throughout the lifecycle of the project. This makes the ability
to spot design problems at the early stages of a project easier and allows
changes to be made in the office rather than on-site.
and all this information is located in various places within an office or in
several offices, sometimes that information can be lost or hard to locate. BIM has the ability to store, record and issue all the
information as a 3D model and with data management tools such as Vault.
maintain the assets, as long all the information has been entered correctly
throughout the project. Bad data in = bad data out. Autodesk has various cloud
based tools that can be used for site inspections. Analysis and simulations can
be run using information such as traffic data to show potential future needs.
project execution plan. For smaller projects, such a plan might be fairly
simple. On a large project with many stakeholders, a highly detailed plan may
be necessary to keep everyone pointed in the same direction. Why do you always
need a plan? With BIM, you design with intelligent objects. You need to know
what intelligence the objects should have from the start of the project. Also,
when you share designs that are based on intelligent objects, a change can
ripple through the whole design.
how much intelligence to add to key model objects; for instance, a grading
plan that will be used for GPS-guided grading will require a higher degree
how and what data will be used over the life of the asset
how and when data will be transferred between project participants
uses over the life of the infrastructure asset. Because the data can be used
for so much more than traditional 2D or 3D CAD data, you may find yourself
asking new questions at the beginning of projects. For instance:
the model be used for fabrication in addition to documentation?
will the model be used in construction?
else can I use the model for? Analysis, simulation, optimization? What
have I always wanted to do that I couldn’t with
2D or 3D CAD-based design approaches?
and how will we share data with other disciplines on the project? Daily?
frequently should we coordinate models contributing to the project?
as they master BIM. Consider enhancing your project plan with a process for
capturing and sharing milestones in the BIM implementation process. When your
team sees and shares the benefits of BIM, it will be easier for them to appreciate
the work they put into defining standards and processes up front. For instance,
the first time an engineer moves a profile and the related model elements and
subsequent documentation updates automatically can be a transformative moment.
No matter how much you understand and read about BIM, it’s those “aha moments”
that drive home why the industry is moving to using intelligent models.

infrastructure successfully. The steps to help you should include:
- Plan to educate staff on BIM; implementing BIM
will require a new way of thinking, as it differs significantly from a traditional
- Identify the standards and rules that need to be
- Account for software and hardware needs; to make
the most of a move to BIM, consider technology that allows you to move project
information from planning to preliminary design to detailed design to construction
without rework or redundancy
- Establish a project plan for each BIM
infrastructure project that outlines lifecycle data needs and processes for
sharing the model
- Document and refine processes
