Requirements Transformation in Construction Design

Abstract: Transformation of performance requirements to technical solutions and production parameters is central for architects and engineers in the design process. The delivery of a new low-carbon economy in Europe puts pressure on the construction industry to reduce the energy consumption in the building stock.Energy requirements are often regulated in national standards or recommended by branch organisations. New methods and tools has been developed to simulate and analyse the energy consumption in buildings and support the transformation of requirements for technical solutions. Today industrialised housing companies suffers from low efficiency in the design and information flow creating bottlenecks in the production process. Matching the energy requirements is of great interest for the construction industry and especially for companies developing industrialised housing system that often have control over the whole manufacturing process. Therefore are three different national standards for energy requirements tested on a industrialised housing system and evaluated in an ICT –environment that supports the design process for industrialised construction. The result of the research shows that the transformation of energy requirements to technical solutions needs well defined design activities based on deliveries through the process. A well defined design process together with a building system is also the backbone for development of ICT support systems.

The BIM Collaboration Hub – A model server based on IFC and PLCS for Virtual Enterprise Collaboration

Abstract: For a long lasting effort and collaboration among several actors, there is a need for integration and consolidation of the building information in a common information hub, a model server. A standardized exchange format, like IFC today, in its own is not enough. If the standardized format is only used in point to point exchange situations, the project and building information will not be integrated neither consolidated.The IFC standard can manage snap-shots of the information, but to manage the whole life cycle, there is a need for a standard like PLCS, Product Life Cycle Support, ISO 10303-239, www.plcs-resources.org, which supports some critical business needs faced by companies as they seek to implement Product Lifecycle Management (PLM) and other broad enterprise-based initiatives. The model servers shall secure collaboration both within an organization as well as throughout an extended enterprise and its various participants. One implementation of an open BIM based model server is the BIM Collaboration Hub based on the model server Share-A-space from Eurostep. The BIM Collaboration Hub was the foundation for the web-based Open ICT Platform in InPro, a 4 year European R&D project which finished in November 2010.At its core, Share-A-space is a standards-based data consolidation and exchange solution. It is built on PLCS, a standard which promises to become a key enabler for process improvements in several service-focused industries such as aerospace and defense.This paper presents the BIM Collaboration Hub, the technologies and how it was used as the web-based Open ICT platform in the InPro project. It presents the next paradigm in virtual collaboration in construction, where the full lifecycle is supported. The discipline specific definitions of objects and relations of the IFC standard are put into this framework and related to the extended functionality of PLCS.
