Virtual Building TimeBuilding Process Real Time

The Project Management System (PMS) will integrate Virtual Building models, Site Processmodels, and external information containers. It will also manage matching and updating of the VBsub models as well co-ordination with building site activities. BPrt = Building Process real time, VBt= Virtual Building time to describe time points in life of Virtual Building (sub)models

- Collaboration subject/context & Form of interaction; design, reviews, purchase, learning, brainstorm, negotiation, discussion,

- Communication content to support interaction; e.g. speech, sound, images, music, video, whisper, body language, 3D objects, control information;…..

- Meeting spaces and room definitions; physical, virtual, static, dynamic, mobile and combinations.

- Collaboration artefacts; communication channels, user applications, and information containers

Communication -New Players

Communication is supported by IT-tools.

Artifacts may be project, organisations, software (also embedded).

Context is the building life cycle (from idea to re-cycling).

The Virtual Building Model.

The virtual building contains all documentation of the buildingincluding drawings, models, documents etc. It will normallycontain redundant information and temporal informationdescribing discipline models and sub models of the buildingover time.

Virtual Workspace

-VW is a set of interconnected design rooms that supports innovative(but also “classical”) design procedures.

-software and hardware Infrastructure supporting the design andconstruction process (access to relevant visualization andcommunication IT-tools)

DIVERCITY - Virtual Workspace

ECPPM Portoroz September 9-11 2002 Prof. Per Christiansson  IT in Civil Engineering  Aalborg University http://it.civil.auc.dk

DIVERCITY -Virtual Workspace definition

'The Virtual Workspace, VW, is the new design roomdesigned to fit new and existing design routines. VW maywell be a mixed reality environment. The VW will host alldesign partners from project start with different access andvisibility (for persons and groups) in space and time to theproject, and will promote building up shared values inprojects. The VW thus acts as a communication space withproject information support in adapted appearances. VWgives access to general and specific IT-tools '

DIVERCITY GOALS

-To improve the process of building design and construction byenabling stakeholders(clients, architects, engineers, contractors,sub-contractors) to operate more efficiently and with betterinteraction

- Research and Develop a Distributed Virtual Workspace that:

Supports Continuous Design between different phases of theprocess (and different technical domains) by using a ModelDriven (integrated) approach

Allows multi-disciplinary project team members to share thesame view about the project through a Visual representation

Supports Collaboration between geographically distant sites

ECPPM Portoroz September 9-11 2002 Prof. Per Christiansson  IT in Civil Engineering  Aalborg University http://it.civil.auc.dk

DIVERCITY GOALS

- bring important added value by integrating, into one seamlessenvironment, recent breakthroughs in different (and for themoment separate) technological domains (global illuminationsimulation, multiresolution techniques, constraint based modelling,acoustics simulation, etc.)

DIVERCITY aims to develop a "shared virtual constructionworkspace" that will allow construction companies to conductclient briefing, design reviews, simulate what if scenarios, testconstructability of buildings, communicate and co-ordinate designactivities between teams. Both synchronous and asynchronousinteraction will be emphasised in this software framework.

THE AEC SECTOR

-Complexity due to a high number of mostly small, and usuallygeographically distant, companies working on one single project

-A major industrial sector in Europé (7% of working population +14% indirect jobs in related sectors)

-Stakeholders (clients, architects, local authorities, residents, etc.)have, on the basis of 2D drawings, different and incompleteunderstandings of the planned construction….

-Life cycle thinking and seamless transition of information andprocess between life cycle phases.

-Complexity due to a high number of mostly small, and usuallygeographically

DIVERCITY - Methodology

A)user requirements capture, user environment design and early prototyping;

B) implementation of DIVERCITY and end user alpha test (done within theDIVERCITY consortium) of basic functionality of the DIVERCITY products(applications);

C)continued implementation and end user beta tests/evaluations of basicfunctionality of integrated framework and DIVERCITY products;

D)final end user evaluation of DIVERCITY, and prototype refinement.

Contextual DesignConceptual Work Models

–Flow, structure representing communication and co-ordination necessary to dothe work (roles, responsibilities, actions / communication topics, and spaceswhich in Divercity are regarded as project internal or project external memoriesand virtual/physical spaces);

–Sequence, showing the detailed work steps necessary to achieve user intents.Sequence models can reveal alternate strategies to achieve the same intent;

–Artefact, showing objects created to support the work;

–Culture, representing constraints on the work caused by policy, culture orvalues, formal and informal policy of the organisation, business climate, self-image, feelings and fears of the people in the organisation, possibility for privacy;

Physical, showing the physical structure of the work environment as it affects thework.

COWI EXPERIENCES

Divercity is an example on a end-user co-defined developed workspace and,to our knowledge, one of the most coherent at the moment and might be thefuture platform for further plug-ins.

The pro-active end user involvement have made significant modifications tothe software architecture as well as to the individual products.

The end-user involvement in the preparation and the planning of testscenarios contributed in ensuring that the VE will meet the requirements ofthe industry.

The IFC-standard which is a core component in the Divercity framework isprogressively been introduced to the Danish construction industry. At themoment COWI is participating in a test of the standard on the new head-quarters for the National Broadcasting Company (DR)

Future Virtual Workspace features

Based on this definition, the future distributed workspaces will have thefollowing features:

-The advanced administration tools for distributed personal, team, and projectinformation repositories;

- accessibility to virtual building models and collaboration environments throughwireless networked workspaces and low cost virtual reality environments;

-appropriate security levels for sharing the information over the inter/intranets;

-process and workflow management tools to support variations in workingpractices between different projects;

-definition and design of new ICT tools to support collaboration andcommunication with end-user.

Divercity has created a virtual workspace for construction, which includessome of the features listed above. The details of Divercity’s CollaborativeWorkspace are discussed later in this handbook.
