Unøjagtig og manglende ledningsdokumentation er hovedårsagen til graveskader i Danmark. En ledningsovergraving er oftest en dyr og tidskrævende affære, og derfor tilstræber både ledningsejere og graveaktører, så vidt muligt at undgå det.De nye tiltag med LER 2.0 er et skridt i retning mod at skabe sammenhængende ledningsdata til at give et bedre overblik og dermed færre graveskader, men anvendelse af nye teknologier kan forebygge graveskader endnu mere.Denne artikel præsenterer erfaringer med anvendelse af 3D- punktsky teknologi (Reality Capture) til registrering af anlægshuller og dokumentation af ledninger under gravearbejdet. Ved et senere gravearbejde vil punktskyerne kunne visualiseres med Augmented Reality til dannelse af et virkelighedstro overblik i både planlægningen og udførelsen af arbejdet. Målet er at synliggøre værdien af konceptet til ledningsejere og graveaktører i forsyningsbranchen.

This report presents the process, findings and user-guide of the development of a real time Virtual Reality with Auralization system allowing building-designers, owners and end-users to listen to a design proposal and provide such people a better foundation for decision-making and a heightened ability to consider the acoustic IE during building design.

Only limited research has been conducted with respect to the use of Virtual Reality for planning of Facilities Management. Through a case study experiment, using only the early stage architectural 3D model of a test building. A Virtual Environment was then generated allowing test persons evaluation the usability of Virtual Reality as a Facilities Management planning tool. Facilities Management, Building Information Model, Modelling and Management and Virtual Reality are individually widely researched. However, this paper contributes to great amount of scientific literature with respect to Facilities Management, by studying the topics in unison. The evaluation of Virtual Reality for Facilities Management planning was divided into a qualitative phase involving interviewing of the test persons, and a quantitative phase allowing test persons to rate their experience in Virtual Reality in a questionnaire.The study revealed that 82 per cent of the test persons found Virtual Reality usable as a planning tool for Facilities Management. The experiment however also showed a wide range of the degree to which the test persons found the tool usable.

This paper describes the development and initial testing of a Virtual Reality withAuralization system. To facilitate a realistic auralization, sound sources wererecorded in an anechoic room and inserted into a test scenario. The scenario waspresented to test persons in order to evaluate the realism of the system, andprovide feed-back ahead of further development.

Automating the transfer of Building Information Model (BIM) data to assess energy performance is still far from straight forward. The approach of using Industry Foundation Classes (IFC) or Green Building Extensible Modelling Language (gbXML) is only justified if the parametric data is accurate and explicit and if the designers are proficient at console coding. Mapping parameters to rigid schemas and calculating quantities and volumes can be time-consuming and require software engineering knowledge. Using Action Research Methodology, two student groups investigate methods of data transfer and parametric data derivation. To ensure correct data transfer, we propose an API-based proprietary pre-computation which connects Revit objects and parameters with an Excel-based Indoor Environment Assessment tool (IV20). IV20 is currently under development at Aalborg University, and it serves us as a set of Business Rules, defining required inputs needed for an energy assessment.This case study focuses on automating features that perform extraction, calculation, and storage of input data, based on a set of predetermined user requirements. Dynamo VPL is used to extract sample information regarding room and element properties, façade orientations, and building surroundings.We conclude that Revit-Dynamo-Excel (RDE) approach can significantly automate data transfer, but it requires explicitly modelled objects, agreed exchange requirements, and a well-defined and communicated calculation method. Our approach does not eliminate IFC interoperability, but rather enhances the proprietary information advancement, prior to export.
