“…Discussion about the emerging 3D terrain measurement capabilities can be found elsewhere (Chemistruck, Binns, & Ferris, 2011;Smith & Ferris, 2010a, 2010bDetweiler & Ferris, 2010), and is beyond the scope of this chapter. However, it is the objective of this section to present the vehicle suspension load analysis based on measured 3D terrain profiles.…”

“…Each method produces a different data representation; therefore, one of the key issues to be resolved is the selection of the gridding method. It is essential to make a good selection, otherwise the results obtained and therefore the diagnosis of the pathology will not be correct (Smith & Ferris 2010). In general, the procedure for levelling interior spaces in a building that is mostly regular produces a homogeneous data set.…”

PurposeGrowing awareness of the importance of preserving the built environment has created an increasing demand for experts capable of performing building inspections to ensure a high level of preservation.Technical surveys include a set of procedures and tests that have become essential tools providing the necessary knowledge required for maintenance, preservation and improvement of buildings.Design/methodology/approach Within this set of inspection techniques, this paper presents a method developed to produce vertical deformation plans from the levelling data obtained from different floors of a building. It also explains how to perform accurate levelling and an outcome analysis to provide displacement maps. Thus, based upon obtained measurements, it is possible to achieve 2D contour maps and 3D surface mapping by means of specialized software that is typically used for cartographic and territorial analysis. The developed methodology provides easier analysis of the deformation of buildings and structures.Consequently, the method produces relatively accurate outcomes that are sufficient to make a proper assessment that facilitates the diagnostic and decision-making process. The case studies analysed show the applicability and usefulness of the procedure. Originality/valueThis sustainable and non-destructive system is an essential instrument for providing valuable and useful information to the specialist. The 2D/3D graphical data displays enable easier analysis of survey results, also aiding comprehension of these results in the context of liability claims.
