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)

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. 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 usually examples of stratified... (read more)

Joint RICS/CICES lecture – Survey4BIM

Joint RICS/CICES lecture – Survey4BIM – speaker: Barry Gleeson , UEL University Square Stratford campus (https://goo.gl/maps/DWF6xdhw3AB2) Speaker: Barry Gleeson MRICS is Programme Engineering Manager for BIM and a stalwart member of the Survey4BIM group. Survey4BIM has successfully highlighted several (5) key geospatial elements that will derail adoption of level 2 and 3 BIM and this joint lecture will focus on the groups work to date (on Accuracy) and its future work programme (Interoperability). Although it might seem that BIM has gone off the boil in the UK of late this is not the case and BIM has essentially started to... (read more)

Software Platform Accelerates As-built BIM Workflow

ClearEdge3D has announced the release of its newest software platform, EdgeWise BIM Suite, which can make the process of creating Revit building models considerably faster than traditional workflows. The platform, which consists of the company’s EdgeWise MEP and EdgeWise Building software, uses new technology developed through a National Science Foundation research grant to automatically extract piping, conduit, round ducting, walls and windows from laser scan point cloud data. During the software’s development phase, the ClearEdge3D team worked closely with the Revit product team to fully integrate the EdgeWise technology with Revit, creating a powerful as-built modelling toolset within the Autodesk...
