concur project summary
CONCUR was aimed at exploiting the developments that were made in Product Data Technology specifically for the construction industry during the mid 1990s. Mechanical, aeronautical, automobile and maritime engineering were successfully exploiting the STEP advances of the 1980s, AP225 and CIMsteel had made a start, but here were technologies aimed specifically at the wider construction industry. In particular, the CONCUR partners wanted to exploit the IAI-IFCs in the processes that were used in the pre-tender phases of construction.

The CONCUR partners examined the processes and the information flows with the aim of using ICT and open standards for integration. The project looked at the project inception stage, the concept design phase with links to power engineering processes, the scheme design phase and estimating. A common thread through the project was the desire to use product models and 3D modelling throughout the process and to move the start of modelling higher up the chain.

Where possible, established commercial software was used so that the project results could be deployed for commercial use. Technical assistance was both received from and given to software vendors. A number of vendors were involved as associate partners and undertook major enhancements to their software to support the goals of the CONCUR project.

Technically CONCUR has made major advances in: inception modelling, using web based Information Management Systems, linking these systems to advanced object oriented Product Data Technology, a method for PDT model merging, a method for using XML to interface with a PDT database, a metadata schema for the IAI, a set of derived attributes for the IAI-IFCs, driving forward the creation of a lexicon of construction terms which will support the needs of both PDT and eCommerce for construction, showing that IFCs can be used for storing models as well as exchanging them, and in methods for browsing and adding to the the contents of IFC models.

CONCUR has helped to move the IAI-IFCs closer to widespread use by using them on industrial information and by critiquing the IFC translators developed by the major vendors of modelling systems.

CONCUR has demonstrated that IFCs can integrate the processes of different companies using different software applications being used for different purposes.

CONCUR partners are deploying the results commercially and have a clearer vision of how to profitably extend the use of PDT further into their businesses.

CONCUR has identified weaknesses and gaps in these technologies and has helped initiate work to improve and strengthen them – The Way Forward.

CONCURProject Summary
concur industry need why undertake the project
Client Demand

Clients are demanding: higher quality, greater predictability of time and cost, faster project delivery, better documentation and better value for money.

Market Differentiation

The construction industry needs: greater involvement in client planning, faster response to client requirements, better defined processes and MOST OF ALLSATISFIED delighted clients.

Increasing Regulatory Drive

Society is expecting: increased safety, improved sustainability, reduced energy consumption, reduced waste, greater accountability and better documentation.

Quantifying Risk

The construction industry needs to: reduce the cost of tendering, improve the accuracy of tenders and quickly quantify the risks associated with a new project.

Integrate the Extended Enterprise

The construction industry needs to: integrate the use of information in a dynamic supply chain, support concurrent working in the supply chain, speed up the processes supporting tendering.

Review Industrial Practice

The partners rigorously examined the processes undertaken by commercial construction organisations when preparing a bid. The results were presented in the form of IDEF0 diagrams with notes. The processes include: client brief, inception design, concept design, scheme design and preparing estimates.

Implement File based Architecture for Tendering

CONCUR prepared a mid-term demonstration which linked the software applications using file tranfers between the applications. The transfer files used comma separated variable, STEP Physical files (IAI-IFC). STEP Data Access Interface was also used. This demonstrated that interoperability was possible but was not commercially robust and flexible.

Implement Client/server based Architecture for Tendering

The second half of the project concentrated on using a web based IMS system to support realistic exchanges including an integration with a STEP database to provide a model server. Significant advances in using IFCs were also made. The results demonstration supported a realistic business scenario and is described in this web site.

Implement Enhanced Production Software Applications

The project encouraged the development of IFC translators by major software vendors to the industry, encouraged the enhancement of existing software to support the new ways of working required by the CONCUR partners, initiated the development of new commercial software applications to support the new ways of working and created prototype software for inception modelling and browsing IFC information models. New approaches for capturing and manipulating construction industry terms were also initiated.

Deploy in Trials

The CONCUR industrial showed a realistic exchange in a demonstration and are starting to implement the technology in their businesses. Taylor Woodrow are using the approach in their supply chain to integrate with architects, structural designers and steelwork fabricators; Fortum Engineering are integrating their internal use of information and Skanska are implementing an integration of 3D modelling, cost estimation and time programming systems using information from a company database of resources.

concur client brief
CONCURClient Brief
  • Determining the client brief is a key role for the principal contractor. The client does not always know how to do this and usually requires assistance to do this. The client will have a business plan within which the new project will perform in terms of finance, operating costs, generating revenue and delivering a profit. The client requires input from the supplying contractor to support his business plans.
  • When the client brief is fully understood and agreed by the client and supplier, the supplier can develop the scheme and prepare a bid and programme for delivering the project.
  • There are systems for capturing client requirements and recording requirement revisions and the supplier response options. One such system is called Dynamic Object Oriented Requirement System (DOORS). This system was trialled in the first half of the CONCUR project and featured in the Mid Term Review Demonstration. DOORS, from Telelogic UK Ltd, can support the whole life cycle of a project. The mid term trial showed how information exported from DOORS could be imported into corporate systems
  • The development of the client brief takes place concurrently with the Inception modelling of a project, the assessment of risk to the supplier and the effect on the potentially new project on the supplier business plan. Currently information is manually transferred between client brief and into inception modelling.
concur inception modeller
Inception Modelling

The developing of an Inception Support Modeller was one of the most research oriented parts of the CONCUR-project. At the start of the project it was quite clear that the inception stage of large-scale construction projects involves a number of heavy and interrelated information processing tasks. Clients have to establish the feasibility of the project. Facility designers and construction companies have to decide how to meet the client requirements. This means that in a relatively short period of time a tremendous amount of not well defined information and knowledge related to all the aspects of power plants has to be processed.

It was quite clear that an Inception Support Modeller could be quite beneficial and potentially could help to support the projects goals.

It was also known that, in principle, Product Data Technology could also be used in the inception and concept design stages where the information is normally less precisely defined.

The solution implemented in the CONCUR-project focuses, as an example, on the international power plant market.

The main characteristics of the approach implemented in the project are (1) the adoption of a three level approach and (2) the application of a hierarchy of power plant objects divided into functional and technical perspectives.

The three level approach, illustrated on the next screen, supports the work of the clients, power plant vendors and construction companies in one dynamic system. Changes in requirements can flow down stream to be solved, and changes in power plant solutions of construction solutions can flow up stream to be evaluated, thus the dynamic system allows for non-monotonic design.

The functional-technical object hierarchy supports the consistent modelling of knowledge in the form of rules of thumb.

Many of the ideas and solutions explored in the Inception Support development tasks have found their way to the industrial partners.

CONCURInception Modeller
concur the importance of inception modelling
Why Inception Modelling?

Inception modelling is a neglected phase of construction projects even though it is a key activity. It is always done but tends to be a stand-a-lone manual process. CONCUR has looked at how company knowledge can be collected and presented to produce initial estimates. The work has not been integrated into the information flow.

Initial Assessment of Projects

Inception modelling takes place when preparing the client brief and results in a first assessment of cost, programme, resource requirement, cash flow and financial risk and ultimately whether or not a supplying company wants to proceed. It could easily interface with corporate financial and risk planning systems. It is potentially a customer facing tool as follows:

Interface with Customers

Inception modelling can be used to support the client in his business planning because it can give him information required to help assess the viability of a project, namely: Initial cost, time to complete, cash flow to first revenue, key figures such as floor area, maintenance cost, operating cost. When combined with his estimate of revenue potential , based on for example floor area, it can support his business planning.

Initiation of Contractor Downstream Processes

Inception modelling is a knowledge based process requiring access to company data on costs and planning. It is difficult to undertake in a generalised way and in concur was limited to numerical modelling , but without shape. However, it could be developed to first-guess the information required by downstream processes such as estimating and programming, and even be used to propose a model for structural engineering design and analysis. This would provide an easy route into starting the use of 3D modelling on a project and the first stages of 3D visualisation

Scope for Development

A number of the CONCUR partners have realised the potential of linking Inception modelling to Product Data Technology and plan to undertake further development.

concur fortum engineering plantpower
Fortum Engineering use a suite of software called PlantPower which have been customised for the purpose of defining the requirements for power plant construction. The design procedure is:

Scoping Module

In order to meet clients requirements, a scoping module called ScopePower is used for identifying a structure of power plant delivery. This is a logical layout based on KKS code, forming a skeleton of the information technical product model for further study

Energy Balance

Energy balance studies are made by Fortum Engineering’s process simulation tool Solvo. These results are defining requirements for power plant processes as input data for further design

Energy Balance Flow Charts

In practice it means, that there is unambigious dependence between energy balance flow charts and IT product model

Design Rules

A knowledge module holding design rules, design dialogues, plant scope and and artificial intelligence facility based on Design++ is used for initial dimensioning of main equipment in order to fulfil process requirements. The results are presented in the main flow diagram.

Dimensions

Dimensioning of main equipment continues for over all dimensions of the site so, that suitable plant layout can be selected. The first cost estimate is carried out in order to support decision making at investment level

Cost Estimation

Knowledge modules support more detailed design on steam turbine plant. Cost estimation on facility level will define costs accurate enough for tendering purpose. Actual cost data is in cost libraries of CostPower, where the commercial software of CM-Pro is used on cost estimation and further budgeting during pre-tender phase

Company IMS

All design, cost estimation and scheduling information are stored in product model and in the attached relational database. In the CONCUR demonstration data was exchanged with IFC files between project partners: Fortum Engineering, Taylor Woodrow and Skanska

concur fortum internal ims information exchange
Most companies have an internal information management system

To support their internal engineering and business processes.

They also have internal protocols for exchanging information between software applications.

The protocols are usually based on proprietary native exchanges because they are information rich.

Why use open standards?

Even though open standards are less rich than proprietary native standards for exchange they offer a common denominator when exchanging information with other companies, especially when active trading relationships are short.

Proprietary standard are not particularly good at handling objects that are not supported by that software. At best they import and export the objects without altering them. At worst they corrupt them of just lose them so that they are not available for downstream activities. This usually happens at the interfaces between different engineering or business disciplines.

There are internal advantages to using open standards when using different types of software or purchasing new software.

Why use a web based IMS?

Easy universal access.

Partner companies like web based project IMS systems because they feel that they have a share in its ownership.

The web based systems can be transferred to the client to support downstream life cycle support.

How has CONCUR used EXPRESS Data Manager™ version 4.0 ?

IMS support – EXPRESS Data Manager™ is used by the CONCUR project to implement a Product Model Server (PMS) as an integral part of the Project Information Management System (IMS). The IMS is responsible to ensure consistency between the contractual document management system and the 3D project database stored in the PMS according to the IAI IFC151 specification. The PMS provides a facility for selective viewing, download and upload of 3D project data and their link to the contractual documents.

CONCUR is making use the ultimate object technology: Objects are defined as industry standard objects in IFC and the ISO Express-X language is used as a data manipulation language (DML) for improving the capability of these objects - independently of any particular software system.

Project database functionality:

Partial download – Using a 3D browser (Promote) to select IFC objects to download using P21 and XML

Upload and merge – Import IFC objects and merge the result using P21 and XML..

XML Access to IFC Models – EDM provides an access interface to objects, their attributes and properties based on XML to enable the integration with material take-off applications in Excel and similar.

IFC Browser - EDM provides the object database used by the TNO IFC Browser application which can view IFC models and be used to add, edit and extract the properties and attributes of the IFC objects in the models.

Calculation of derived Attributes - EXPRESS Data Manager™ provides a virtual machine that interprets all Express and Express-X executable statements. CONCUR has used this capability to add semantics to the IFC151 schema by adding ‘Derived Attributes’ such as volume and surface area of the IFC 1.5.1 objects. This is a convenience to any application that does not include a geometric engine.

What is EPM Technology EDM?

EXPRESS Data Manager™ (EDM) is a suite of applications providing an out-of-the-box solution for easily creating data-models conforming to international standards.

EDM\'s pick-and-place icon driven user interface allows anyone to easily learn EDM\'s data modeling methodology.

Once familiar with EDM, the user can quickly implement data-models in conform-ance with ISO 10303 (STEP), and other standards like IAI, STEP/NC, OIL & GAS and P-LIB making use of XML, Java and other environments.

How can EPM Technology EDM help construction industry users?

EDM helps users to take a great leap towards cost efficient and reliable use of ICT in their organizations.

EDM helps users to take ownership of their product data by using a single data source based on standards.

EDM helps users to apply a unified methodology and a set of products that take them from concept to solution.

EDM can assist users in the change of the design world from 2D to a 3D object based environment.

The interoperability and re-use of building models will translate to increased collaboration amongst industrial partners.

In particular the knowledge stored in IFC based building models could be used for facility management and other purposes during design, construction and after the building project is completed.

What can EDM do?

A powerful object-oriented database management system capable of being a users single source of information.

A web enabler due to its thin-client technology. Complete applications written in EXPRESS and EXPRESS-X are fully executed by the EDM-expressVM™ (Virtual Machine) within the database. These applications are controlled through local EDM interface™ calls.

A unified methodology for product data solutions. All functionality of the system is configured by EXPRESS and EXPRESS-X schemas, which are the ISO and industry standards for information requirement specifications.

An EXPRESS-G modelling environment which uses EDM visual-Express™ to design users data models and to publish them, for example on the web.

A Rule Engine to define a users corporate knowledge by constraining information models using the rules capabilities of EXPRESS and EXPRESS-X.

A standards solution in its support for EXPRESS (all statements, expressions, built-in functions and procedures), Part 21, and SDAI.

concur express data manager edm 5
Whats new in EDM version 4.5

EXPRESS-X implementation has been extended - among others with full exception handling - to be the one built-in database control language (including EXPRESS) for EXPRESS Data Manager™ 4.5. It provides the user with functionality and performance for building entire applications on top of the users information models at reduced costs for programming and maintenance. With the one language for modelling, storage, and use of information models, the user avoids technology compatibility problems.

The Business Object layer of EXPRESS Data Manager™ 4.5 hides the complexity of an underlying data model and adds application specific functionality. The Business Object defines views and methods for the underlying database by means of the powerful EXPRESS based Query and Update Language in EXPRESS Data Manager™ 4.5. Business Objects are created on the server instead of locally, enabling thin clients and reducing network traffic. Business Objects tailor the same underlying information to the needs of the many disparate applications of data.

The Query and Update Language of EXPRESS Data Manager™ 4.5 is using EXPRESS-X. Any EXPRESS-X logical expression can be passed to a query as a parameter. This functionality is fully comparable to SQL.

Skanska Teknik has since 1999 worked on the development of a new tool to combine information about the different aspects of a project. The purpose and functionality of the system have been defined by Adina Jägbeck and Lennart Klintmalm. It has been named "Facets". Introduction 1Facets

Facets deals with information from CAD, cost estimation and process planning. Or, rather, it allows the user to create – otherwise sub-understood – relations between the various aspects, and display them. The development started as a part of a EU-supported project - Concur. The system has been built by Solibri OY and is certified for import of ifc 2.0 from CAD. It contains functions for two different project stages.

Facets Site Developer – functions for the concept phase

The use context for Facets Site Developer is the very early project phase. The prerequisite for using Facets in this stage is that one needs to graphically investigate different alternatives for accommodating a space requirement schedule on a site and, at the time, calculate investment costs and rental levels based on rough estimates of.

Facets Site Developer was developed during the spring of 2001 in cooperation with a group of project developers in Skanska Hus, - Ingela Lindholm and Anders Rådestad.

Facets Scheme Design – functions for scheme phase

The use context for Facets Scheme Design is co-ordination between design, cost estimation and process planning. The system imports CAD-information in IFC-format, while cost recipes and process schedules are imported as databases. By relating building objects to cost items, recipes and activities the system automatically creates, on-line, quantity take-off item and activity, calculation of recipe based costs and displaying building a 4D-view of time schedules.

The functions in Facets Scheme Design were developed during 2000 and 2001 in cooperation with a production group within Skanska Hus, including Katrin Eriksson.

concur pdm meta data structures for documents
End users require metadata to automate the sorting, finding, storing and exchanging of files and documents.

The CONCUR Project has specified a simple PDM schema for documents for use in the project IMS.

The schema is in line with Ifc 2.0

A simplified version has been incorporated in Ifc 2x

Metadata Criteria:

LINK - Easy link to PDT (Ifc 1.5.1 compliant in 1999)

SIMPLICITY - Simple to understand and implement

NEEDS - Satisfying the CONCUR Demonstration industrial need

SUPPORT - IT vendor support

Analysed solution and described on the next sheet.

The CONCUR schema is being used by IT vendors in ProCure

  • Further information
concur ifc derived attributes why
IAI-Ifc contains direct data on building elements such as:

Height, Width, Length

However, users are also interested in properties like:

Volume, Surface Area, Area

So CONCUR extended the standard Express Ifc 1.5.1 schema with derived property values which can be derived using the shape representation in Ifc 1.5.1

The EPM Technology Express Data Manager database can calculate the Derived Attributes in real time

The TNO IfcBrowser can view them via the client interface, calculating them on the server when the user requests them.

CONCURIfc – Derived Attributes- Why?
  • Further information
concur ifc model merging why
Commercial modelling software applications support their own specific disciplines and sometimes ignore or lose information from other disciplines!!!

End users often need to combine models from different disciplines

End users often need to mix and match alternative solutions

CONCUR developed a simple Model Merging technique using Express-X

The technique can merge models complying with the same Ifc schema

If the construction and related industries are to exploit object modelling to the full, they will need sophisticated model merging technology.

CONCUR has not addressed the legal, responsibility ownership or model locking issues associated with multiple users taking parts of models, modifying them and merging the results back into the model.

The model merging is controlled by the Web based project IMS system and undertaken by the EPM-EDM database.

concur model merging rationale
The civil engineering companies have delivered alternative building solutions to the project database. The project database will have the facility to maintain the confidentiality of information where necessary.

Fortum Engineering can view both alternative schemes and can merge either with the original conceptual design for the plant and equipment or with an alternative design for the plant and equipment. It is also possible for Fortum to merge models for other parts of the plant into the same model.

Model merging requires the EPM-EDM part of the project database. Model merging instructions are assembled via a web based form.

The EPM-EDM software can also be used to extract individual objects from the Models.

The merged models have been loaded into the project database as IFC FE1+SK1 and IFC FE1+TW1. After the merging has been completed, the source and merged files are deleted from EPM-EDM.

The next view shows merged models.

.

CONCURModel Merging Rationale
concur ifc property sets
Part of the content in IFC files is put in the properties.

Property Sets can be defined to combine several properties in a subgroup.

This way we can define relations between different properties.

This saves a lot of space because we can refer to a specific property set instead of a set of references to properties

A property set can have 0 to many properties.

One property can be found in several property sets.

Compare Solutions

The different solutions offered by the building and civil engineering contractors are compared.

Try Combinations of Models

Model merging offers the opportunity to try different combinations of plant and building models. For example the mechanical engineering plant model may have changed or the principal contractor may want to try a new arrangement in an existing building model or try an existing plant arrangement in a different building. This could could occur when buildings are designed for a specific country or climate.

Choose the Most Appropriate Solution

The principal contractor chooses the most appropriate combination to incorporate in the bid.

concur bid to client
The bid to the client usually includes:

The Proposed Scheme Solution

In the past, proposed scheme solutions were usually described on drawings which were contractual documents. In the future it is expected that this information will be presented as models which can be re-used. The models can be used to create views (drawings) for construction purposes. Models are presenting challenges to how contracts are written and undertaken. CONCUR has explored some of the practical technical requirements.

Cost Plan

All bids require a price. How this is provided varies from country to country and even varies for different types of construction project. Although detailed bills of quantities are still prepared for pricing, the construction industry is tending to use cost plans which are easier to prepare and use. They also relate to the object oriented way of thinking and working. A typical UK Cost Plan format for commercial buildings is shown which will be recognisable to most of the European construction industry. Taylor Woodrow and Skanska, in particular, have addressed how models can support the preparation of cost plans. External software partners have developed this further.

Programme

The bid usually includes a programme for executing the work. Fortum Engineering and Skanska have developed this aspect during the project.

Specifications

Specifications are a key component of bids. This is the speciality of STABU. The TNO IFC Browser can be used to insert specification information relating to building objects into the models.

Schedules

Schedules of principal components such as doors and windows. Schedules can be created from the information models

A common language for the Construction Industry

The LexiCon provides definitions and descriptions of concepts that are of interest for the construction industry.

The definitions and descriptions are structured according to a model that allows both human and computer interpretation.

The conceptual language of the LexiCon may use any lexical human language to express its contents. The formal definition of a concept consists of its set of associated properties, whereas the names and descriptions given to that concept allow humans to quickly associate that concept with their own understanding of the meaning of that concept.

Framework for information exchange

The LexiCon concepts live in the background, providing templates that help structuring information in such a way that this information can be interpreted by different applications, as long as these applications have access to the LexiCon concepts. Hence, end users won’t see much of the LexiCon in practice because the LexiCon will often be hidden by the user application’s interface.

Examples of applications using the LexiCon are:

CAD applications which want to combine gemotrical object descriptions and quality data

Product information systems and Catalogues describing products

Specification systems, cost estimating system and the like.

CONCURResults and Exploitation
concur technical results
Common concepts for naming and definition in AEC (Lexicon)

The development of common concepts for naming and defining construction terms for international use and in multiple languages starting with Dutch, English, German, Norwegian and French.

STABU have also developed tools for collecting and manipulating definitions.

Moving IFC product models into use

CONCUR has contributed to the the development of IFCs and provided criticism to the developers. The major contribution was in the area of document metadata.

The project partners have provided a test bed for trialling the advanced use of IFCs with industrial information.

CONCUR has demonstrated early applications of IFC v1.5.1 and IFCv2.0

CAD system translators for IFCs have been tested and feedback has been provided to software vendors.

Encouraging software vendors

IFCs were originally intended for exchanging information. CONCUR has show that they can also be used for storage.

CONCUR has shown how IFCs can be used in in STEP (Express) object databases for both storage and manipulation (Model Merging).

The partners showed how XML could be used to interface with models in a STEP database. This showed that models can be used without the need for sophisticated modelling systems. (none CAD tools)

The partners developed a prototype IFC/Browser for viewing and extracting information from IFC models. (a none CAD tool)

Technical Issues

IFCs and their translators are still immature and are very limited in their application. Serious general commercial exploitation is unlikely to happen before 2004. There is a need for funding to develop the depth and breadth of the models, especially in the product area.

Currently cost and time are not being supported by vendors.

There is a need for JAVA 3D development for viewing to replace the limited VRML.

The modelling technology needs to keep pace with XML developments so that IFCs can be integrated with eCommerce applications

Technical adoption

Vendor uptake and translator production is at least 9 months behind model development. Different vendors are using different versions of IFC which leads to incompatiblity

There is an increasing vendor interest in IFCs, especially from the smaller vendors.

concur results partner commercial exploitation
Taylor Woodrow

Taylor Woodrow is making extensive use of project web sites. The company is wanting to move from a project to product way of doing business. A live construction project is using IFC and CIS standards for exchanging information down and integrating the supply chain. The company is now starting to address the human and organisational issues. The project results are influencing the TW ICT investment programme for product and project modelling.

Skanska

Skanska is developing and investing in the the Facets work where modelling is supporting the programming and estimating for projects. IFCs are a important part of this thinking.

Fortum Engineering

Fortum Engineering are also moving to a product way of doing business. CONCUR has helped the company to start integrating processes and the results are the basis of data warehouse plans for corporate information. The project has helped Fortum to integrate the use of information so that risks can be quantified quickly.

STABU

The Lexicon development is the basis of an international standardisation initiative to identify a taxonomy of construction terms with definitions. These can be used for eCommerce purposes and will eventually provide a logical integration with Product Data Technology and specifications. STABU are also exploiting the work commercially by populating the taxonomy with construction product and service information which will complement their existing business.

All partners have much better knowledge and expertise with which to make investment decisions

Significant interest from the Smaller Vendors

Smaller vendors usually provide specialist software

Smaller vendors see interoperability as a route to a wider market

Smaller vendors can react and customise more quickly

Commercial Software is expensive to Develop

Research Projects and partners do not have the resource to develop commercial software which requires 10x the resource required for a prototype.

Commercial software requires maintenance and a commercial support infrastructure

Therefore it is essential to involve commercial vendors

Open standards are developing Slowly

Many vendors are wary of open standards

With proprietary standards being an issue

Open standards development is under funded and often voluntary

Vendors are driven by the market which has an 18 month cycle

Demand & demand – and you might get – sometime in the not too distant future!!!

Make better use of information models

CONCUR used IFC based object models throughout the project where the objects are the building elements. The project explored the limits of using these models and found that although the objects can be used there is a great need to deepen and broaden the IFCs. It is also clear that models which are native to modelling systems will always be richer than standard models but with the penalty of limited or no interoperability. The partners found that it is essential for users to create project models from an object point of view based on the building elements. Major advantages of using IFCs were the facility to exchange objects between different sectors of industry without losing or corrupting information and the ability to exchange and store property and attribute information in addition to geometry for use in other systems, such as estimating. The effective use of standard models aids the change from project to product ways of thinking.

Do more work on the inception area

During the project it became clear that the front end work with the client and the inception modelling area requires more R&D effort. This is a key area which can initiate models, programmes and cost plans. There are clear links with knowledge management, data warehouses and artificial intelligence systems to ‘first guess’ project models to speed up the conceptual work downstream. There is a need for Building Wizards.

Make links to E-commerce & business

There is a need to develop links between the worlds of Product Data Technology and eCommerce. This will widen the usefulness of project models to support the needs of estimating, purchasing and facilities management. This will move product modelling into the mainstream of business. This will result in models being used by software other than modelling systems. Access will be required to extract and add information to the models by applications such as spreadsheets. The VTT XML interface to a STEP database is a move in this direction. It is important to have compatibility between PDT, EDI, catalogue formats and eCommerce.

Continue RTD investment

European and national bodies need to find ways to support the development of model schemas and research into related applications. It is of general use throughout the industry but beyond the scope of individual companies. The work is currently being moved forward by member based (not for profit) organisations which supply funding for the work.

Involve vendors

It is essential that the software vendors are involved in the R&D work. Experience has shown that vendors value being kept informed about developments. Within CONCUR software vendors became involved towards the end of the project as associate contractors where they implemented the research ideas and brought them to market. This was a good fit with their development programmes which are usually less than 24 months. Only commercial vendors have the skills and resources to commercially robust software and support.
