BIM (Building Information Modelling)

BIM is the process of collaboration and coordination of project information to provide a single-model interrogative database. The process begins at the start of the design phase of a project and continues through to the handover to the client and may be continued post handover as a FM database.

Included in the BIM are the following components;

Building Analysis and Energy Modelling.
A collaborative process whereby building model data is passed to an energy analysis software to model building performance taking into account the fabric & structure of the building, the finishes, usage and occupancy factors. The results of the analysis are then returned to the building model.

2D Documentation - consisting of drawings, schedules and design specifications. Documents are issued to define design and construction information at key deliverables dates in strict accordance with the Scope of Works.

3D Building Elements modelling.
The 3D model is developed to in conjunction with the design process to provide a fully coordinated solution. During this process component and equipment metadata is added into the 3D model to enable systems design analysis to be performed against the building analysis and energy model requirements.

4D Construction Program scheduling analysis.
Construction planning and design planning information is added to the relevant elements of the graphical model to provide build sequence simulations. These simulations are able to provide to provide a visual timeline of the construction program and also clash detection of concurrent events.

5D Cost Estimating integration.
Materials and equipment costs along with labour rates costs are added to the relevant components within the model to provide an accurate cost schedule of the project. Procurement schedules can be integrated into the construction program to improve the scheduling analysis.

6D Facilities/Lifecycle Management.
The BIM process continues into the Facilities Management/Lifecycle Management of the building. Refurbishment or changes to tenant requirements can be introduced to the model and analysed for compatibility with existing plant or system capabilities. New energy analyses can be run to check compliance or offer improvements utilising newer technologies.
