They are not intended to go‘in depth’ into practical issues but to act as a basic guide on a particular topic and in particular, on procedures and regulations which may govern how a particular aspect of the survey is carried out.  \n1. What is a Measured Building Survey?  \nA measured building survey is the collection of measured data to enable the surveyor tobe able to produce plans, elevations or sectional drawings of a building. Measured data can be delivered as two dimensional drawings but more commonly three dimensional‘BIM ready’ solid or wireframe models are the requested deliverables.  \n2. Why is a Measured Building Survey required?  \nThe existing detail of a building may be required for a wide range of purposes, most commonly for refurbishment of the property. A measured survey may also be required for historical archiving or lease plans to define a space.  \nMeasured building surveys may also be required for:  \n• Sale, acquisition, letting or land registry  \n• Valuation or taxation  \n• Facilities management or services layout  \n• Redevelopment, alterations or structural changes  \n• Health & safety, e.g. fire plan layout  \n• Interior design layout  \n• Licensing requirements  \n• Modelling, visualization  \n• Rights of light, party wall issues.  \n“Whatever the project, accuracy in planning is  \nthe key.”  \nIt is worth bearing in mind that a survey prepared for one purpose is not necessarily going to be of sufficient accuracy or detail to be used for another. For example, surveying the overall outline of a room to define the lettable area may well be done ata lesser accuracy than when data collection will enable an architect to design structural alterations to the building, e.g. the difference between an unconnected survey and a fully connected survey.  \nWhatever the project, accuracy in planning is the key. A thorough survey will lessen the possibility of making costly mistakes at a later stage, as it will be lessen the likelihood of discovering unforeseen problems.  \n2  \nCLIENT GUIDE TO MEASURED BUILDING SURVEYS ISSUE 4 FEBRUARY 2016 ©TSA  \n4. Factors affecting a Measured Building Survey  \nThe majority of firms who are collecting data within the Geomatics sector will do so according to an industry recognized standard produced by the Royal Institution of Chartered Surveyors (RICS) . The RICS publication is titled ‘Measured Surveys of Land Building and Utilities 3rd Edition’. This document is regarded as the ultimate reference source by measured building professionals as it states from a client perspective what the required specification is with relevance to specific projects.  \nThere is a key section within this publication which discusses types of survey, identifying three distinct categories: ‘Connected’,‘Semi-connected’ and ‘Unconnected’. The classification of the survey will dictate the measurement practices employed to produce the requested deliverable.  \nThe guide states an Unconnected survey is one that using simple methods which do not enable one part of the survey to be related to another. This type of survey is traditionally associated with plans used for the determination of lettable areas, where the area of a specific region is required but its relationship to its surrounding space is not.  \nA Semi-connected survey is where one floor (normally the ground floor) is surveyed with all parts connected by instrumental control. Other floors are matched by assuming verticality of common features.  \nIf major structural changes are proposed then it is usually the case that a . survey maybe requested. This is defined as a survey where all floors are instrumentally related to a common survey control framework.  \n“Which classification of survey requested will dictate the measurement practices employed t","cbCaipYUzZoVsC5V","https://ap.wps.com/l/cbCaipYUzZoVsC5V","pdf",5100616,"English","# What is a Measured Building Survey?\n# Why is a Measured Building Survey required?\n## Common purposes\n# Factors affecting a Measured Building Survey\n## RICS standards and survey classifications\n### Connected, Semi-connected, Unconnected\n## Scale, accuracy and precision","[{\"question\":\"What is a measured building survey used to produce?\",\"answer\":\"It collects measured data so the surveyor can create plans, elevations, or sectional drawings.
