Building Information Modeling (BIM) for existing buildings — Literature review and future needs
TL;DR: Results show scarce BIM implementation in existing buildings yet, due to challenges of (1) high modeling/conversion effort from captured building data into semantic BIM objects, (2) updating of information in BIM and (3) handling of uncertain data, objects and relations in B IM occurring inexisting buildings.

Mobile 3D mapping for surveying earthwork projects using an Unmanned Aerial Vehicle (UAV) system
Sebastian Siebert,Jochen Teizer +1 more
TL;DR: The performance evaluation of a UAV system that was built to rapidly and autonomously acquire mobile three-dimensional mapping data and its execution for the generation of 3D point clouds from digital mobile images is presented.

BIM implementation throughout the UK construction project lifecycle: An analysis
TL;DR: This research demonstrates via 92 responses from a sample of BIM users that collaboration aspects produce the highest positive impact and is most often used in the early stages with progressively less use in the latter stages.

Automatic Creation of Semantically Rich 3D Building Models from Laser Scanner Data
TL;DR: A method to automatically convert the raw 3D point data from a laser scanner positioned at multiple locations throughout a facility into a compact, semantically rich information model that is capable of identifying and modeling the main visible structural components of an indoor environment despite the presence of significant clutter and occlusion.

Model-based interpretation of range imagery
Darwin Kuan,Robert J. Drazovich +1 more
TL;DR: A model-based approach to interpreting laser range imagery using a viewpoint-independent volumetric model based on generalized cylinders to give guidance for goal-directed shape extraction from low level image features.

Deriving construction features from an IFC model
TL;DR: This paper describes the reasoning process implemented to extract construction-specific design conditions from a BIM model based on user-defined queries, and provides a critique of the IFC’s to support the querying process.

CSG-based object recognition using range images
Wei-Chung Lin,Tsu-Wang Chen +1 more
TL;DR: A CSG (constructive solid geometry) -based system to recognize 3D objects from range images by segmenting an object in a range image into primitive surface patches with the simplest geometric characteristics.

Symbolic signatures for deformable shapes
Salvador Ruiz-Correa,Linda G. Shapiro,Marina Meila,G. Berson,Michael L. Cunningham,Raymond W. Sze +5 more
TL;DR: This work develops an algorithmic framework for recognizing classes of deformable shapes from range data using a newly introduced symbolic-signature representation that is robust to deformations, as opposed to a numeric representations that is often tied to a specific shape.
Semi-automatic building reconstruction integrated in strict bundle block adjustment
TL;DR: In this paper, a new approach for semi-automatic building reconstruction integrated in hybrid photogrammetric adjustment is described, which uses a unique way of modelling building primitives by boundary representations (B-rep), making use of a special way of formulating surfaces, thus getting rid of the overhead parameters usually connected with B-rep models.
