CONCUR Project Summary Next Back Directory Return -3 - 4 CONCUR was aimed at exploiting the developments that were made in Product Data Technology specifically for the construction industry during the mid 1990 s. Mechanical, aeronautical, automobile and maritime engineering were successfully exploiting the STEP advances of the 1980 s, AP 225 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. 4 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 3 D modelling throughout the process and to move the start of modelling higher up the chain. 4 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. 4 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 e. Commerce 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 contents of IFC models. 4 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. 4 CONCUR has demonstrated that IFCs can integrate the processes of different companies using different software applications being used for different purposes.
CONCUR Industry Need- Why Undertake the project? 4 Client Demand 4 Clients are demanding: higher quality, greater predictability of time and cost, faster project delivery, better documentation and better value for money. 4 Market Differentiation 4 The construction industry needs: greater involvement in client planning, faster response to client requirements, better defined processes and MOST OF ALL SATISFIED delighted clients. 4 Increasing Regulatory Drive 4 Society is expecting: increased safety, improved sustainability, reduced energy consumption, reduced waste, greater accountability and better documentation. 4 Quantifying Risk 4 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. 4 Integrate the Extended Enterprise Next Back Directory Return -4 - 4 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.

CONCUR Project Tactical Approach 4 Review Industrial Practice 4 The partners rigorously examined the processes undertaken by commercial construction organisations when preparing a bid. The results were presented in the form of IDEF 0 diagrams with notes. The processes include: client brief, inception design, concept design, scheme design and preparing estimates. 4 Implement File based Architecture for Tendering 4 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. 4 Implement Client/server based Architecture for Tendering 4 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. Next Back Directory Return -6 - 4 Implement Enhanced Production Software Applications 4 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.

CONCUR Client Brief 4 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. 4 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. 4 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 Next Back Directory Return -15 - 4 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 4 Inception Modelling Next Back Directory Return -16 - 4 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. 4 It was quite clear that an Inception Support Modeller could be quite beneficial and potentially could help to support the projects goals. 4 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. 4 The solution implemented in the CONCUR-project focuses, as an example, on the international power plant market. 4 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. 4 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. 4 The functional-technical object hierarchy supports the consistent modelling of knowledge in the form of rules of thumb.

CONCUR The importance of Inception 4 Why Inception Modelling? Modelling 4 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. 4 Initial Assessment of Projects 4 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: 4 Interface with Customers 4 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. 4 Initiation of Contractor Downstream Processes Next Back Directory Return -18 - 4 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 3 D modelling on a project and the first stages of 3 D visualisation 4 Scope for Development 4 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 Internal IMS & Information exchange 4 Most companies have an internal information management system 4 To support their internal engineering and business processes. 4 They also have internal protocols for exchanging information between software applications. 4 The protocols are usually based on proprietary native exchanges because they are information rich. 4 Why use open standards? Next Back Directory Return -24 - 4 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. 4 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. 4 There are internal advantages to using open standards when using different types of software or purchasing new software. 4 Why use a web based IMS? 4 Easy universal access. 4 Partner companies like web based project IMS systems because they feel that they have a share in its ownership. 4 The web based systems can be transferred to the client to support downstream life cycle support.

CONCUR EPM Technology’s Express Data Manager™ (EDM) - 1 4 How has CONCUR used EXPRESS Data Manager™ version 4. 0 ? 4 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 3 D project database stored in the PMS according to the IAI IFC 151 specification. The PMS provides a facility for selective viewing, download and upload of 3 D 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. Next Back Directory Return -39 - 4 Project database functionality: 4 Partial download – Using a 3 D browser (Promote) to select IFC objects to download using P 21 and XML 4 Upload and merge – Import IFC objects and merge the result using P 21 and XML. . 4 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. 4 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. 4 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 IFC 151 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.

Introduction 1 Facets 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". 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 Next Back Directory Return -49 - The use context for Facets Scheme Design is co-ordination between design, cost estimation and process planning. The system imports CAD-information in IFCformat, 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 4 D-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 Model Merging Rationale 4 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. 4 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. 4 Model merging requires the EPM-EDM part of the project database. Model merging instructions are assembled via a web based form. 4 The EPM-EDM software can also be used to extract individual objects from the Models. 4 The merged models have been loaded into the project database as IFC FE 1+SK 1 and IFC FE 1+TW 1. After the merging has been completed, the source and merged files are deleted from EPM-EDM. 4 The next view shows merged models. Next Back Directory Return -75 - .

CONCUR Compare Scheme Solutions 4 Compare Solutions 4 The different solutions offered by the building and civil engineering contractors are compared. 4 Try Combinations of Models 4 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 occur when buildings are designed for a specific country or climate. 4 Choose the Most Appropriate Solution 4 The principal contractor chooses the most appropriate combination to incorporate in the bid.

CONCUR Bid to Client The bid to the client usually includes: 4 The Proposed Scheme Solution 4 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. 4 Cost Plan 4 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. 4 Programme 4 The bid usually includes a programme for executing the work. Fortum Engineering and Skanska have developed this aspect during the project. 4 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.

CONCUR Technical Results 4 Common concepts for naming and definition in AEC (Lexicon) 4 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. 4 STABU have also developed tools for collecting and manipulating definitions. 4 Moving IFC product models into use 4 CONCUR has contributed to the development of IFCs and provided criticism to the developers. The major contribution was in the area of document metadata. 4 The project partners have provided a test bed for trialling the advanced use of IFCs with industrial information. 4 CONCUR has demonstrated early applications of IFC v 1. 5. 1 and IFCv 2. 0 4 CAD system translators for IFCs have been tested and feedback has been provided to software vendors. 4 Encouraging software vendors 4 IFCs were originally intended for exchanging information. CONCUR has show that they can also be used for storage. 4 CONCUR has shown how IFCs can be used in in STEP (Express) object databases for both storage and manipulation (Model Merging). 4 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) 4 The partners developed a prototype IFC/Browser for viewing and extracting information from IFC models. (a none CAD tool) 4 Technical Issues Next Back Directory Return -97 - 4 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. 4 Currently cost and time are not being supported by vendors. 4 There is a need for JAVA 3 D development for viewing to replace the limited VRML. 4 The modelling technology needs to keep pace with XML developments so that IFCs can be integrated with e. Commerce applications 4 Technical adoption 4 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 4 There is an increasing vendor interest in IFCs, especially from the smaller vendors.
CONCUR Industrial Results What has CONCUR Achieved? 4 Used commercially available software 4 Used open standard product models 4 Established a web based multi-user environment for exchanging project information 4 Demonstrated a link between Electronic Document Management Systems (EDMS) and a Product Data Technology (PDT) object database 4 Demonstrated with real industrial information 4 Deployed on real projects Next Back Directory Return -98 - 4 Contributed to the development of open standards 4 Has shown that bidding can take less time and effort
CONCUR Results: Partner Commercial 4 Taylor Woodrow Exploitation 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. 4 Skanska is developing and investing in the Facets work where modelling is supporting the programming and estimating for projects. IFCs are a important part of this thinking. 4 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. 4 STABU Next Back Directory Return -99 - 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 e. Commerce purposes and will eventually provide a logical integration with Product Data Technology and specifications.

CONCUR - The Way Forward 4 Make better use of information models 4 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. 4 Do more work on the inception area 4 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. 4 Make links to E-commerce & business 4 There is a need to develop links between the worlds of Product Data Technology and e. Commerce. 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 e. Commerce. Next Back Directory Return -103 - 4 Continue RTD investment 4 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. 4 Involve vendors 4 It is essential that the software vendors are involved in the R&D work. Experience has shown that
