Whether using topographical surveys for the design of new build developments, laser scanning for measured building surveys and the creation of BIM ( Building Information Modelling) of existing buildings prior to refurbishment and modification, or for as-built survey of completed buildings – Merrett Survey Limited provides all of these services.
This type of work has been completed across all sectors and all size of projects including:
Commercial sites, housing, inner city
In the public sector
Building Information Modelling
Of course BIM ( Building Information Modelling ) is often involved on these projects and we can provide scan to BIM of existing building archicture, structure and MEP – services. But we can still provide the standard 2D floor plans, elevations and sections together with lettable floor plan calculations if required. BIM modelling can be provided in Revit format or other 3D model formats suitable for input to a variety of BIM software types.
The UK Government mandated the use of BIM under the 2011 Construction Strategy, which mandated its use at the maturity level 2 on all HM / Central Government procured projects by April 2016. Since then we have found many clients, even on non central Government and even private sector projects requesting data suitable for use in BIM. The most basic reasoning is to greatly improve the efficiency of the UK construction sector but it should create savings throughout the lifetime management of a building or other element of the built environment. BIM can be applied to any project – it is not restricted to buildings.
BIM level 2 can be described as;
“BIM Level 2 maturity encompasses the generation and management of structured information models comprising all named data-sets used throughout the lifecycle of a built asset.
Information models will include a series of domain and collaborative federated models. The models, consisting of both object-oriented 3D geometrical and non-graphical data, are prepared by different parties during the project life-cycle within the context of a common data environment. Using agreed information exchanges, project participants will have the means necessary to provide defined and validated outputs via digital transactions in a structured and reusable form. Appropriate and proportionate measures will be applied to manage the security risks that affect a built asset, asset data and information.”
BIM Level 2 requires all project and asset information, documentation and data to be electronic, which supports efficient delivery at the design and construction phases of the project.
