In the blogs in this series, we look at the structure of the BIM Model Level of Definition Table
- What the Model can be Relied Upon
- Output
- Parametric Information
- Critical Interfaces and Logic
- Construction Requirements
- Project Costs
- Project Logistics and Offsite Activities
- Project Facilities Onsite and Offsite
- Notes and Associated Project Documents Based on Model Information
In this blog, we have a look at what Critical interfaces and Logic is required. As a side note, the Employer Activities are not listed here. Typically, the Client BIM Consultant will evaluate the Stage Complete data drops to give the go-ahead and authorize payment.
During the Definition Modelling, the Conceptual Model is developed to conform to the spatial and environmental constraints. Tolerancing is important for foundations for assembly of modular systems, and movements of the building are considered. Thermal expansion can be significant, as are responses to natural disasters like earthquakes.
The Design Model finalizes the dimensions of the systems.
The Build and Commission Model captures the actual dimensions on site and starts tracking the assets. Smaller unmodelled items like conduits and small pipes are scanned during construction as their placement might be lost during concrete casting and other construction.
During Handover the systems are tested, and transducers installed to monitor performance. This information is also captured in the model.
Lastly, during operations, any modifications or maintenance activities are tracked and monitored.
