Whilst there is a seismic shift to the 3D Environment when we talk about measured building surveys, frequently particularly on small scale projects the specification from clients often only requires 2D outputs. These outputs are generally presented as Floor Plans, Elevations and Sections to represent the building or structure being measured.
Irrespective of whether a full BIM model or more traditional 2D deliverables are required, our method of data capture remains the same. From one-bedroom apartments to complex retail sites each and every project is now captured using 3D Terrestrial Laser Scanning.
Historical, Rural and Heritage buildings are particularly challenging to model in BIM as walls, floors and ceilings are often deformed both horizontally and vertically. These features are common to these types of buildings and make the process of producing a detailed BIM cost prohibitive.
Detailed Elevations, Cross Sections and Floor Plans when derived from rich point cloud data can show the nature of buildings in a very detailed way. This form of presentation, although simplistic with regards modelling intelligence, can be used very effectively to supplement the BIM model.
All measured surveys follow the professional guidance as published by the Royal Institution of Chartered Surveyors: Measured Surveys of Land, Buildings and Utilities (3rd edition).
