Building Information Modelling (BIM) is the process used to create three-dimensional representations of assets, with corresponding information. The concept assists with the visualisation, quantification and simulation of design, construction and other building processes.
3D BIM is one of the most popular BIM dimensions which all construction companies are familiar with. It is a three-dimensional geographical structure of a building, containing the X-axis, Y-axis, and Z-axis.
In 2016, the Government announced that all public construction projects must be built using BIM. This calls for the adoption of Level 2 BIM within all parts of the design and build process. Prior to the creation of a BIM, there are certain considerations that are required. If there is no full understanding of the requirements, then the final deliverables, timescales, and costs could be severely impacted.
Firntec Surveys recommend consideration of the following points prior to finalising the BIM specification:
The Golden Thread
As a part of the governments effort to enhance safety in high-rise buildings, the government are making it mandatory to use Building Information Modelling (BIM) and BIM companies for residential projects with six or more storeys. The consultation document’s Part C, titled “Duties that run throughout a building’s life cycle,” focuses on establishing a “golden thread of information” that will run through the entire lifespan of the building, from the design stage to occupancy. To accomplish this, digital tools and systems will be utilised to store and effectively utilise the essential information.
The Importance of Level of Detail
The level of detail ensures the client is aware of the difference between the model detail and the model information. Below are the definitions for LOD and LOI, at Firntec we have merged these into one to create simplicity and ease for the client.
Levels of Model Detail (LOD) – Description of graphical content of models at each of the stages defined for example, in the CIC Scope of Services.
Levels of Model Information (LOI) – Description of non-graphical content of models at each of the stages defined for example, in the CIC Scope of Services.
