Building Information Modelling at MFA
We use BIM to streamline the production of drawings and information to provide quality and efficiency within our work streams. We offer our clients this service giving them the opportunity to improve their management systems, integrating BIM for the whole lifecycle of the building.
The Building Information Model, which encompasses the digital description of every aspect of the building is defined in the following levels: –
• BIM Level 1 comprises a mixture of 2D and 3D at Concept Stage. A common data environment, such as cloud based storage, is required at this level.
• BIM Level 2 requires collaboration and all parties to be able to export data in a common file format, which is accurate and efficient when combined together. This as a minimum level for all public-sector work in the UK.
• BIM Level 3 aspires to manage the whole life cycle of the building including concept, construction, use and decommissioning within a single central model. It involves all parties related to the design, commissioning, maintenance and running of the building to utilise BIM technology.
Survey
Accurate ‘Point Cloud’ laser scanned surveys are commissioned at the outset of the project to assist in setting up our BIM model this allows the design to develop smoothly from concept design onwards without the need to input survey data in the later stages which can delay the design process.

Central Model
A central design model allows different construction phases of the project to be held in the same model. ‘Phasing’ can assist in the production of existing, demolition, and proposed drawings simultaneously which can be useful in working with historic structures and listed buildings. The model can be interrogated in 2 and 3D and create plans, sections, elevations and views assisting the design process. ‘Plan Regions’ assist in simplifying views when dealing with complex layouts or neighbouring buildings with multiple floor levels creating easily legible drawings.

Collaboration
The BIM environment means that all stakeholders can follow the design progress at any time, by means of a fully interactive 3D model. It means less room for error due to a seamless collaboration between the design team; we can view structural and mechanical updates in real time and advise on issues. Consultants can see the design development as it happens allowing full co-ordination.

Quality
Working with BIM also provides embedded quality control when it comes to the detailing of construction elements with functions such as clash detection. The specification and schedule of work becomes integral part of the BIM model. The process is thus not only very transparent, but also more comprehensive and less prone to error. The production of drawings becomes more efficient as all the information can be drawn from the central 3D model.
Due to a restriction with access during construction we were asked to alter the structural frame from concrete to steel on a project whilst the contractor was on site. Working with BIM allowed a smooth transition to the new design whilst communicating effectively with the structural engineer.
The Future
MFA continue to develop its use of BIM technology and ensuring all team members develop appropriate skills allowing full collaboration within the design team. It is hoped as our clients become more familiar with the technology they will utilise it to benefit their businesses and building management during the lifecycle of the building.
