LOD 300 BIM Modelling Services Australia
Industry: Construction and Engineering Industry Location: Australia
Technology & software used
- Autodesk Revit, Autodesk NavisWorks
- An Australian based construction and engineering company approached Australian Design and Drafting Services with a project, to create information rich intelligent BIM for a residence in a 6 storied building with a basement for car parking. The construction area, spread across 10,500 sq. ft. The client wanted BIM with LOD 300, for architectural, MEP and structural disciplines. The primary reason of outsourcing BIM services was to avail detailed documentation, to detect and mitigate clashes at an early stage and make the construction process efficient and cost effective.
Outcome & benefits
- Engineering assumptions made by the BIM experts, for the missing structural data, were 90% accurate.
- Even after the delays in receiving structural details and input files from the client, the project was successfully executed within the set time frame of 6 weeks.
- Clash detection helped clients detect and mitigate clashes at an early stage, and save the massive costs of mitigating these clashes at the time of actual construction.
- The material takes offs, and project scheduling estimates provided, reduced the overall time and cost of construction, and made the process seamless, coordinated and error free.

What LOD 300 BIM modelling actually commits to
LOD 300 BIM modelling means every modelled element is accurate in quantity, size, shape, location and orientation — a contractual commitment, not a style preference. Our LOD 300 work defines the element matrix up front: which categories are modelled to 300, which remain at 200, and which are excluded, so the coordination and quantity workflows downstream know exactly what they can rely on. Elements are modelled with real products where specified and generic placeholders where design is unresolved, flagged as such.
Where LOD 300 pays off
The value shows up in coordination and quantities: clash detection against an LOD 300 model finds real clashes rather than placeholder noise, and quantity surveyors can take off structure and major services with confidence. For contractors, the model becomes the single reference that subcontract shop drawings are checked against, which is where documentation disputes go to die quietly instead of expensively.
We deliver LOD 300 modelling as standalone scope or as an uplift of existing design models, with the element matrix and QA evidence included so your BIM execution plan obligations are met with documentation, not assertion.
The commercial reality is that LOD commitments increasingly appear in consultant agreements and contractor BIM obligations without the signatories fully pricing what they promised. We help clients on both sides of that: authors who must deliver a contracted LOD economically, and recipients who need an independent check that the model they were handed actually meets the level its transmittal claims. Both engagements start with the same element matrix conversation.
Pricing follows the element matrix directly: LOD 300 across every category costs real money, while LOD 300 on structure and major services with LOD 200 elsewhere often serves the project identically at two-thirds the fee. That conversation — what actually needs the commitment — is where we usually save clients more than our margin.
For teams new to formal LOD frameworks, we also provide a short definitions briefing with the engagement — fifteen minutes that aligns everyone on what 300 does and does not promise, and prevents the mid-project dispute that misaligned expectations otherwise guarantee.
