The construction pilot in GENIAL: implementing the GEN vision in the construction domain

Abstract: Among the emerging range of new working habits that appear to best preserve companies position in competitive markets, the Global Engineering Network (GEN) Initiative has recognised the reuse of internal and external engineering knowledge as one of the very promising approach to be considered by companies elaborating their business strategies. With that respect, the GENIAL project devotes its mission to the promotion of a new king of market places where actors capture and retrieve on-line a wide range of engineering products and services. The GENIAL architecture is first depicted that emphasises its main components. The GENIAL approach is then described that allows a information provider to play as a Value Added Service Provider in the GENIAL sense. This approach is then illustrated by dedicated cases in the construction domain that evidenced the benefits of the concepts from a user point of view.

Construction application of a gen-network : uniform access to standards, products and company information

Abstract: "Facing an increasing competitive environment where flexibility and adaptability to change are the obliged route to success, building and construction companies have to continuously renew their working habits while keeping business processes under quality, time and cost control. In the Architecture, Engineering and Construction (AEC) domain, the wide diversity in terms of the object built, but also associated to the geographical dispersion of actors and building sites makes such an agility even more crucial. Considering the design and tendering phase of a construction operation, the architects and construction engineers have to efficiently select the manufactured products that will best suit the project while complying to its numerous constraints. Beyond the functionality, performance and cost characteristics, a suitable product has also to conform to the applying regulations and standards, be eventually accompanied with a corresponding technical agreement, offer acceptable delivery solutions on the building site. Moreover, once identified within a manufacturer catalogue, the product has to be integrated into the architect or engineer application desktop, whether it be a CAD, specification writer or quantity take-off application. Addressing these needs, the Global Engineering Networking (GEN) initiative is promoting the reuse of company internal and external engineering knowledge through the emergence of new kind of global market places where actors publish and retrieve on-line a wide range of engineering information and services. In particular, The Construction Pilot in EP 22 284 GENIAL project demonstrates over the AEC domain, the relevance of new generation of Information Technology infrastructures supporting the erection of Value-Added Service Provider (VASP) sites that materialise the GEN vision, i.e. allowing information and services to smoothly be retrieved where required whilst the succeeding company is concentrating on its core competencies. With such an infrastructure, whether it is through material, performances, manufacturer, regulation or price discrimination, the appropriate component, document or service is rapidly and cost effectively brought on the designer desk for the best value of the overall project. On the other side of the communication pipe, the supplying partner gains the opportunity of reaching an enlarged audience as IT now commonly break any geographical distance. In practice, three major information publishers and a building contractor in Europe initiate the GEN network in the AEC domain through the erection of VASP sites offering product, company or document related information. User queries are governed by various standard (EPIC, UNICLASS) or corpus specific (BATIBASE, EDIBATEC) classification systems. Relevance of the overall approach is demonstrated through the presentation of a large variety of such queries for the various information corpuses used : Techcom company and product information, BIC company, product and document, REEF regulation documentary corpus or EDIBATEC product information."

PerDiS: persistent distributed store for virtual enterprise concurrent engineering *

Abstract: The availability of a host of software systems for the architects, the engineers and more generally for the construction practitioners has changed the business practice and modified the construction processes. Most of the project data are stored in some electronic form and most of the activities from the brief down to facility management resort to these data. The term Virtual Enterprise (VE) is more and more used to refer to this new complex information technology infrastructure. Exchange and sharing of technical data between construction project's partners, all along the project life cycle, is an important requirement for all participants in a VE. During the last few years an important effort has been undertaken in different research projects to define the software infrastructure of the future VE. While data modeling was mainly based on STEP methodology and norms, software solutions in these works were extremely varied. Studies cover distribution of data and applications, concurrent access as well as security, authentication and data ownership. Among these works we can cite those of NIIIP (and its derived works in SHIIP and SPARS) in US and European ESPRIT projects like VEGA and GENIAL. Nevertheless, the problem of sharing and concurrently accessing data by different partners during a product life cycle still far from being solved. In this paper we present a new approach to build a software infrastructure for the VE. It is based on a platform of persistent-distributed and shared memory called PerDiS. In this approach memory is shared between all applications, even located at different site or running at different times. Coherent caching of data improves performance and availability, ensures that applications have a consistent view of data, and free developers from manually managing object location. Persistence by reachability, based on a distributed garbage collector frees programmers from dealing with explicit data storage. PerDiS offers transactional mechanisms and checkpointing as well as notification when data is dirty. Applications can defines their security policy and data access right based on a task/role model. Distribution granularity can be tuned at application level and/or PerDiS platform level. This allows an easy porting of existing applications where default distribution granularity can be adopted and shift this delicate problem from programming/object level to the applications/VE level for new application development. To port STEP existing applications, we implement the STEP Data Access Interface (SDAI) on the top of PerDiS after extending its main concepts to meet the requirements of distribution, concurrent access and data security. We will show some experiment results and performance measurements. * This work is partially sponsored by PerDiS Esprit Project (22533).

A survey of internet-oriented technologies for document-driven applications in construction open dynamic virtual environments

Abstract: "Various technologies ranging from standards for data exchange and product / process modeling, to integration through the use of object-oriented technologies, have been experimented and used in order to highlight the benefits of information and communication technologies in the construction domain. In particular, this last decade has seen a tremendous activity in new specifications and developments of standards and architectures for enterprise application integration. Indeed, integration and seamless communication between software applications (proprietary and commercial) are increasingly becoming fundamental issues tackled by a variety of emerging technologies. However, all these latest IT developments didn’t have the expected impact on the construction industry. This is due to several factors, including poor investment in construction IT by SMEs, and mismatch between IT innovations and Construction industry needs. In fact, behind the global issue of application integration within the (real or virtual) enterprise, appear a lot of architectural problems (along with the “right” selection of tools, toolboxes and infrastructures) that take a critical dimension in the case of open systems and standard issues. The building sector is essentially characterised by its fragmentation, with a high proportion of SMEs involved in the design and build process of Construction projects: this means, from a macroscopic point of view, that designed infrastructures must be adequate to support Extranets and Virtual enterprises. Consequently, the problematic is not only to ensure internal communication between systems as in a single, even large, company, but to provide the required capacity to exchange information and collaborate outside the boundaries of the information systems constituting the IT infrastructure of a company, including means to organise the flow of information and the co-ordination of tasks. To address the issues of communication and interoperability, several routes have been explored and are still under development: after an initial phase related to bulk exchange of documents, middleware has become the focus, with investigations around CORBA or DCOM (for middleware-oriented application integration), and MOM (for the routing and formatting “on-the-fly” of messages). More recently, new architectures have been suggested, especially the now well-known 3-Tier based architecture and application servers (Client desktop – middle-tier Web or application server – DBMS/persistent storage). Eventually, technologies dedicated to the Web has risen, particularly the XML technology, and Java-oriented technologies like JSP and servlets. Driven by the identification of intra- and inter-company business processes and information / process requirements of the Construction domain, and also on case studies and experiments conducted in previous European projects, including VEGA, GENIAL and CONDOR, this paper proposes a survey and first evaluation of open Internet-oriented technology and standards for use in open dynamic virtual environments, and analyses the potential usefulness of some current technologies, specifically MOM, CORBA, XML, and application servers (for the handling of business objects). The paper also highlights the benefits of using XML, as a technology for flexible and dynamic representation of complex objects (including documents) and their stream-based interchange, along with distributed object frameworks such as CORBA for remote access to data. Finally, the paper concentrates on the need related to the design of an infrastructure for application integration and tasks collaboration, and elaborates on how recent IT fit into architectures required for the specific needs and peculiarities of the construction industry. 1.
