Revit & BIM

3D MODELS & CLASH DETECTION

Need to resolve potential conflicts with other trades in your project?

Welcome to the wonderful world of BIM!

Building Information Modelling (BIM) is an intelligent digital process used to plan, design, construct, operate and maintain buildings and infrastructure. Revit is the industry standard software for BIM, and is Drawable’s preferred tool for the 3D BIM drafting we provide for construction projects of all sizes along Australia’s eastern seaboard.

Build, develop & maintain models

In the BIM process, models comprise both geometry (the physical representation of elements) and data, which enables construction teams to confirm and coordinate design information within a virtual environment.

We guide our customers through the process by building, developing and maintaining Revit models to help the construction keep to timeline, from Shop Drawings to As Built stage. Our BIM specialists support project managers by attending design coordination meetings – either in person or remotely – making changes flagged by the project BIM coordinator and rectifying clashes.

Fill in our one-page Revit Specification Sheet and we will help you determine complex requirements such as Level Of Development (LOD) or other terms that may be a source of confusion. (For a detailed explanation of LOD, read our blog Find Your Level.)

From site establishment to client handover, the Revit technicians at Drawable can lead electrical, air conditioning, plumbing, fire (wet and dry) security, data/voice and audio visual contractors through the entire delivery of projects by generating elements of the model for all trades up to LOD 500.

After installation is complete, Drawable also has the expertise to assist with Facility & Asset Management, which involves maintaining the operation of buildings and infrastructure, plus long-term Lifecycle BIM of the facility.

BIM coordination

Another service we offer is to lead the BIM coordination on behalf of the builder to ensure the modelling philosophy and management is maintained throughout the project. However, the primary purpose of this process is clash detection.

Within the model, clash or collision detection predicts conflicts between trade services – such as a mechanical duct running through an electrical cable tray, for example – allowing contractors to resolve potential conflicts at design stage. This is an invaluable cost and time-saving tool for trade professionals working to the accelerated schedules of modern construction.

Our technicians analyse and assess the client’s requirements, ensuring they are incorporated into the Revit model. We utilise web-based management systems for file distribution and to maintain communication throughout clash detection and resolution, design changes, and the construction/installation process.

Drawable’s fully equipped boardroom is ideal for hosting coordination meetings to resolve clashes between the trade, architectural and structural models on our wall-mounted screen. The Drawable team will also chair, lead and direct meetings if required, in order to achieve a fully coordinated model. We then provide detailed minutes and illustrated reports (including jpegs of clashes) within 48 hours of meeting close.

Benefits of BIM

Even though the Australian market is relatively new to the BIM environment, we find our customers see a significant return on their investment in this model-based approach:

  • Shared Revit models mean less duplication and reworking of drawings between trades through regular collaboration, which ensures that designs, systems and structures are coordinated.
  • By ensuring all the contractors on a project have this consistent access to the same detailed models, BIM dramatically increases time efficiency.
  • If BIM Coordination starts from site establishment, issues or sizing problems with elements (such as fire service pipes, for example) can be resolved before their manufacturing deadlines.
  • Navisworks clash detection means conflicts can be detected and resolved during BIM coordination meetings, well before construction and installation on site.
  • BIM coordinators, builders and contractors can view projects in incredible detail, zooming in on areas of limited space and even spying through walls to see if a potential change will affect services on the other side.
  • Model elements are able to carry extensive data including make, model, specs etc, so they can be selected, ordered and tracked automatically.
  • Contractors have a better understanding of the job and enhanced scheduling of labour requirements and material delivery.

Put simply, BIM improves the transition between design and construction, which leads to greater cost predictability – and, of course, savings.
