Håndbok 138 - Modellgrunnlag, Krav til grunnlagsdata og modeller

Håndbok 138 Modellgrunnlag med veileder og vedlegg stiller krav til hvordan grunnlagsdata og modeller skal bestilles, utarbeides og leveres i vegprosjekter. I prosjektbestillingen avgjøres det om planlegging, prosjektering eller bygging skal gjennomføres modellbasert eller tegningsbasert (les mer om prosjektbestillinger i Håndbok 151 Styring av vegprosjekter). Hvis prosjektet gjennomføres tegningsbasert, gjelder ikke kapittel 3 Modeller i denne håndboken. For prosjekter som gjennomføres modellbasert, gjelder hele denne håndboken.
Håndboken beskriver tre roller:
1 Oppdragsgiver:
Statens Vegvesen representert ved prosjekteier, prosjektleder, planleggingsleder, prosjekteringsleder eller byggeleder
2 Rådgiver:
planleggere og prosjekterende som er ansatt i Statens vegvesen, eller ansatte i private firma som utfører oppdrag for Statens vegvesen
3 Entreprenør:
private firma med underleverandører som utfører oppdrag for Statens vegvesen
Håndbok 138 Modellgrunnlag inngår i Statens vegvesens kvalitetssystem. Oppdragsgiveren oppgir hvilken versjon av håndboken som gjelder i prosjektbestillingen eller konkurranse- grunnlaget for prosjektet.

ICE BIM 2012 is the second major event organised by the Institution of Civil Engineers (ICE) on Building Information Modelling.

…01 Introduction
Mike Chrimes
Director of Engineering Policy and Innovation Institution of Civil Engineers

ICE BIM 2012 is the second major event organised by the Institution of Civil Engineers (ICE) on Building Information Modelling. It reflects the ICE’s commitment to leadership in this area. ICE members have devoted many hours working with government, clients and other stakeholders to ensure that infrastructure assets benefit from the capabilities of systems we generally refer to as BIM.
The effective capture and reuse of information or data has long been recognised as a key driver for improvement in organisation and incentive performance. In this interest BIM is just as relevant to assets in the built environment, the economic infrastructure and the building sector alike.
While we are working hard with government to ensure the UK reaps the benefit of the adoption of BIM across infrastructure, it is important that we share the knowledge of best practice in this area.
BIM 2012 is one opportunity, and with it we are encouraging stakeholders to provide us with case studies of their own experience to enable us to support our learned society objectives of sharing civil engineering knowledge for the benefit of society.
Over the next 12 months we will continue our advocacy, working with other professional institutions and stakeholders to ensure optimum delivery of BIM in the best interests of both industry and society. This means an approach that considers the whole life cycle from inception through construction, operation and finally decommissioning
and reuse.
Much of my professional career has been spent in locating data on older structures that had been lost or forgotten. BIM offers the potential for this generation to secure current data for the future.…

GeoDesign provides the third phase of GIS evolution

…Ball: I’m really interested in the combination of the indoor design tools, with CAD tools being the leader there, and the outdoor design tools made available through GIS. It’s also an interoperability story as these worlds come together.
Miller: I think that’s a classical view about the difference between CAD and GIS, that CAD is indoor and GIS is outdoors. I believe both of those premises are being challenged. CAD is moving into site planning, and GIS is moving into the building space. Many large buildings, such as campuses and airports are being managed using GIS. There are also many site design tools being overlaid with CAD systems. There’s an overlay and blur, and a collision zone between CAD and GIS. There are also interoperability questions, if you’re used to working a particular toolset whether GIS or CAD, you want to do everything in that environment because you’ve invested in the skills to work in that area and you don’t want to learn new technology. But I think that this will play out over time, and there will be room for CAD in geographic space, and for GIS in the CAD space.…

Potential for using intelligent 3D city models for airports

…Today there are two key candidate standards for the description of such intelligent city models, namely CityGML (OGC), and IFC (Building Smart). The former is a GML (Geography Markup Language) application schema developed for the overall spatio-semantic modeling of cities, while the latter, IFC (Industry Foundation Classes) is targeted more at the design and construction process for buildings. While we believe that both have roles to play, this article will focus on CityGML and its potential for the modeling of transportation infrastructures, and more specifically that of airports.…

OGC City Geography Markup Language (CityGML) Encoding Standard

…0.1 Motivation
An increasing number of cities and companies are building virtual 3D city models for different application areas like urban planning, mobile telecommunication, disaster management, 3D cadastre, tourism, vehicle and pedes- trian navigation, facility management and environmental simulations. Furthermore, in the implementation of the European Environmental Noise Directive (END, 2002/49/EC) 3D geoinformation and 3D city models play an important role.
In recent years, most virtual 3D city models have been defined as purely graphical or geometrical models, neglecting the semantic and topological aspects. Thus, these models could almost only be used for visualisation purposes but not for thematic queries, analysis tasks, or spatial data mining. Since the limited reusability of models inhibits the broader use of 3D city models, a more general modelling approach had to be taken in order to satisfy the information needs of the various application fields.
CityGML is a common semantic information model for the representation of 3D urban objects that can be shared over different applications. The latter capability is especially important with respect to the cost-effective sustain- able maintenance of 3D city models, allowing the possibility of selling the same data to customers from different application fields. The targeted application areas explicitly include city planning, architectural design, tourist and leisure activities, environmental simulation, mobile telecommunication, disaster management, homeland securi- ty, real estate management, vehicle and pedestrian navigation, and training simulators.
CityGML is designed as an open data model and XML-based format for the storage and exchange of virtual 3D city models. It is implemented as an application schema of the Geography Markup Language 3 (GML3), the extendible international standard for spatial data exchange and encoding issued by the Open Geospatial Consor- tium (OGC) and the ISO TC211. CityGML is based on a number of standards from the ISO 191xx family, the Open Geospatial Consortium, the W3C Consortium, the Web 3D Consortium, and OASIS.
CityGML defines the classes and relations for the most relevant topographic objects in cities and regional mod- els with respect to their geometrical, topological, semantical, and appearance properties. “City” is broadly defined to comprise not just built structures, but also elevation, vegetation, water bodies, “city furniture”, and more. Included are generalisation hierarchies between thematic classes, aggregations, relations between objects, and spatial properties. CityGML is applicable for large areas and small regions and can represent the terrain and 3D objects in different levels of detail simultaneously. Since either simple, single scale models without topology and few semantics or very complex multi-scale models with full topology and fine-grained semantical differenti- ations can be represented, CityGML enables lossless information exchange between different GI systems and users…

INSPIRE Infrastructure for Spatial Information in Europe D2.8.III.2 Data Specification on Building – Draft Guidelines

.…Building – Executive Summary
This document presents spatial data specification for European data related to the theme “Building”. Finding a common definition for buildings in Europe is challenging. Some entities may be considered as buildings in one country, and not in another one. The definition proposed in this document is the following: A building is a construction above and/or underground which is intended or used for the shelter of humans, animals, things, the production of economic goods or the delivery of services and that refers to any structure permanently constructed or erected on its site.
Relations with other themes
Several other INSPIRE themes describe real world constructions (like network infrastructures). Some of them could be seen as buildings depending on the point of view (like for example a bridge). This document mainly focuses on the physical description of real world entities seen as buildings. It also includes other constructions required for environmental applications that are not already described by other themes. An important characteristic of buildings is their capability to provide services. Because this information is covered by other INSPIRE themes related to facilities (Utility and governmental services, production and industrial facilities, agricultural and aquacultural facilities), this document provides only a simplified classification of building services. Furthermore, building theme classes share relations with addresses, cadastral parcels and geographical names themes.
Existing data and standards
There are nowadays many databases describing buildings. These databases are mainly produced by well identified organisations, usually cadastral and mapping agencies of each member state. Most of these data are vector data, mainly 2D, with comparable levels of details. In order to encourage the publication of these data as INSPIRE data, the specifications of these existing data have been considered. Future need for building data, like for example for 3D representations, have also been considered. Finally, existing standards on buildings, mainly related to specific thematic aspects, have been integrated within this data specification, when appropriate. Main concepts of the the OGC standard CityGML have been adapted and adopted to design the various profiles of the data model of theme Building.
Use cases
Building data are often base data required for thematic applications. The main ones identified for this data specification document are census and statistics, risks management, environment, urban expansion, infrastructures management and mapping. The intention of this data specification is to cover most of these use cases, depending also on the existing data.
This data specification addresses the Noise Directive, the Air Quality Directive, the Energy Performance of Building Directive and the Population and Housing Census Directive. The Flood Directive and the project of Soil Directive have also been taken into account.
Data model
The main objects represented in the data model are buildings, other constructions, building parts and building units. These objects can be characterised by geometrical representations (2D, 2.5D or 3D, with different levels of detail). Temporal attributes allow to describe their life cycle (construction, renovation and demolition dates). Buildings are characterised by an attribute describing their physical aspect and another one related to their use. Many other thematic attributes have been included. In order to improve the usability of the data model, four profiles have been defined:
- TheCore2Dprofilecontainstheelements(classesandattributes)themostcommonlyusedand present in existing datasets. Geometrical representations are various 2D representations, with a possible elevation value. The information included in this profile is intended to be part of the implementing rules.
- The Extended2D profile is a semantic extension of the previous one with additional attributes (material of construction, etc.), classes (building units) and references to other data (like cadastral data).
- The Core3D profile is has same semantic as the core2D profile and enables simple 3D representations.
- Finally, the Extended3D profile is an extension of the core2D profile to rich 3D representations at different levels of details. It also includes the possibility to represent facade textures.

SmartMarket Report: The Business Value of BIM for Infrastructure (2012)

Building Information Modeling (BIM) is having a profound affect on construction industry project delivery and processes. Previous MHC research has shown that within the commercial building sector, the use of BIM is rising rapidly especially among the contractor community. The new SmartMarket Report, The Business Value of BIM for Infrastructure, examines how BIM is being used on infrastructure projects including roads, bridges, dams, water treatment facilities, power plants and transportation facilities. The report examines the use of BIM on these projects, the drivers and obstacles to future use and the impact that BIM is having on infrastructure project teams as well as internal and external collaboration. The study also looks at BIM’s impact on building processes including the increased use of prefabrication and modularization as well as the overall affect that BIM and these processes have on improving productivity factors including schedule, cost, quality, sustainability and safety.

The 60-page report contains new market research data as well as several cases studies highlighting the use of BIM on different infrastructure projects and thought leader interviews that demonstrate the differing perspectives around infrastructure BIM. Download your free copy today.
