Recent studies show a great potential of improving construction productivity through using real-time applications to measure change orders and other objects to create as-built. As an enhancement to this promising concept, this paper presents the process of implementation of an efficient framework for as-built Building Information Modelling (BIM) using a new Scan Station that enables contractors to acquire accurate data and create and update the asbuilt models. A novel framework designed and assisted in the conversion of the raw 3D point cloud data from a laser scanner positioned at multiple locations of a facility into a compact and semantically rich model. The result of the study was compared with two other as-built models using mobile and terrestrial lidar scanners to understand the capability of each for building information modelling. It was found that the framework using the new Scan Station has a great potential to collect accurate data that can be transferred to BIM for creating as-built models. The results show that the accuracy of fine objects' dimensions varies from -2% to +2%. The comparison of the test results with our previous experiments using different scanners shows that every scanner has its own advantage for each job in construction.

ABSTRACT:Three-dimensional models with photographic textures have become a usual product for the study and dissemination of elements of heritage. The interest for cultural heritage also includes evolution along time; therefore, apart from the 3D models of the current state, it is interesting to be able to generate models representing how they were in the past. To that end, it is necessary to resort to archive information corresponding to the moments that we want to visualize.This text analyses the possibilities of generating 3D models of surfaces with photographic textures from old collections of analog negatives coming from works of terrestrial stereoscopic photogrammetry of historic buildings. The case studies presented refer to the geometric documentation of a small hermitage (done in 1996) and two sections of a wall (year 2000).The procedure starts with the digitization of the film negatives and the processing of the images generated, after which a combination of different methods for 3D reconstruction and texture wrapping are applied: techniques working simultaneously with several images (such as the algorithms of Structure from Motion -SfM) and single image techniques (such as the reconstruction based on vanishing points). Then, the features of the obtained models are described according to the geometric accuracy, completeness and aesthetic quality. In this way, it is possible to establish the real applicability of the models in order to be useful for the aforementioned historical studies and dissemination purposes.The text also wants to draw attention to the importance of preserving the documentary heritage available in the collections of negatives in archival custody and to the increasing difficulty of using them due to: (1) problems of access and physical conservation, (2) obsolescence of the equipment for scanning and stereoplotting and (3) the fact that the software for processing digitized photographs is discontinued.
