BIM

The land surveyor is collecting more data indoors. Not because of climate change, but because metropolises continue to expand and urbanites increasingly live, shop, work and recreate in huge edifices. Outdoor infrastructure has to be monitored and maintained. Indoor infrastructure too requires proper management. A key prerequisite is accurate, detailed and up-to-date information. So facility managers need information on interior space: floor plans, 3D models and other (geometric) data. Integrated drawings, geo-data and non-graphical data in a computer storage medium is a Building Information Model (BIM). A BIM is an n-dimensional digital representation of a building, where ‘n’ may vary... (read more)

BIM: Building Information Model

Standards and Interoperability for the AEC market

A Building Information Model (BIM) is a digital representation of physical and functional characteristics of a building. Construction and management of buildings involves many stakeholders, so that proper sharing of information over the entire lifecycle of a building is very important. The Open Geospatial Consortium (OGC) is developing BIM standards that promote efficient web-based information sharing in the Architectural, Engineering, Construction and building Ownership and Operation (AECOO) markets. BIM standards are crucial for increasing productivity, more and more important in a world struggling to recover from problems related to real-estate financing. Standards reduce costs in design, construction and... (read more)

Bringing BIM Down to Earth

‘BIM’ is a hot topic in the industry, receiving regular coverage at many conferences, seminars and webinars. A lot of companies predict that it is one of the ‘next big things’ for the future, and a not inconsiderable number of companies are already working with BIM today. And that’s a good thing! But it is perhaps wise to look past the hype and keep our feet firmly on the ground. Tomas Sandström from Adtollo brings some nuance into the BIM discussion in this column. BIM stands for ‘building information modelling’, or perhaps ‘building information management’. The best thing about BIM... (read more)

BIM: Steppingstone in Disaster Management

A Building Information Model (BIM) is a digital representation of a building. Such a model acts as a shared database for constructor, owner and operator to aid in managing a building construction and its facilities throughout its entire lifecycle. The geometric and semantic entities of the database describes elements such as walls, slabs, stairs, windows and doors; their materials and relationships between them. In addition to geometric/topological and semantic information, BIMs also provide highly accurate and detailed data about the current state of building elements. BIMs have won much attention recently; their use in the architecture/engineering/construction (AEC) industry is rapidly... (read more)

Collaborative BIM Tools for Crossrail

Bentley Systems, USA, has announced two initiatives to support the construction phase of Crossrail through London - Europe’s largest construction project. The initiatives are aimed at integrating the whole Crossrail supply chain to create best practices in information modelling for construction. They are in keeping with the UK’s Government Construction Strategy, which calls for replacing adversarial cultures in projects with collaborative ones. To get to this stage, Crossrail’s Enterprise License Subscription (ELS) for Bentley’s application software portfolio will be broadened to serve the extended “Crossrail enterprise”, now encompassing its Tier 1 contractors. Crossrail’s ELS connects project participants through the... (read more)

Heritage BIM on the Move

Point Cloud Management Strategies in Cultural Heritage Documentation

Building information modelling (BIM) is becoming a useful approach in the documentation and enhancement of historical structures in a system termed 'historical BIM' (HBIM). It is not easy to convert point clouds into a 3D model since the buildings concerned often have very irregular geometry. Therefore, more semi-automatic parameterisation tools are needed. Portable, user-navigable HBIM databases offer interesting potential to broaden the use of cultural heritage information, as this article shows. Historical building information modelling (HBIM) can be defined as a semantic-aware database of historical buildings, in which the geometric model is connected to descriptive multi-source information. Historical buildings are... (read more)
