The role of information management in the development of a strategic model of buildability

Abstract: The key to the successful irnpiernentation of buildability lies with the effective management of information through all stages of the project life cycle and across functional divisions. The majority of building design errors occur not because of the lack of information, but the lack of management of infortnation. Buildability requires information affecting the quality of project decision making tO be timely, relevant and effectively communicated to the decision makers.A strategic management model of buildability has been developed based on the working definition that buildability is "the extent to which decision made during the whole building procurement process, ultimately,facilitate the ease of construction and the quality of the completed project'! This strategic model is underpinned by the conviction that information technology offers the means to overcome the space and time communication problems which have beset previous attempts to introduce effective buildability programmes. The capacity to process and manage large quantities of data is seen as an essential attribute of buildability. The approach adopted is that of a holistic view of Factors which we likely to impact on not only the design and construction process, but of the total procurement process. This allows the boundaries of' the buildability management model to be adjusted to be appropriate to specific project coridirions. This paper will describe an information management framework which will support the implementation of the buildibility management model.

Automated Optimization of Steel Reinforcement in RC Building Frames Using BIM and Hybrid GA

Abstract: Design of steel reinforcement is an important and necessary task for designing reinforced concrete (RC) structures. Currently, steel reinforcement design is performed manually or semi-automatically using computer software such as ETABS, with reference to building codes. These methods are time consuming and sometimes error-prone. With the aid of advanced BIM technology, steel reinforcement design could be automated for fast, economical and error-free procedures.This paper presents a BIM-based framework for automated optimization of steel reinforcement in RC building frame using developed three-stage hybrid genetic algorithm (GA). Optimization includes selection and alignment of steel reinforcement in RC building frame for the minimum steel reinforcement area, including longitudinal and shear/confinement steel reinforcement. The first and second stages optimize the longitudinal reinforcement while the final stage optimizes the shear/confinement steel reinforcement incorporating design code (BS8110) and buildability constraints. A three-storey RC building frame is analysed to check the applicability of the developed optimization framework and its improvement over current design approaches. The results show that the developed optimization framework can minimize the steel reinforcement area quickly. Automated 2D view of RC elements is then created to visualize the optimized steel reinforcement results.

Information-based representation paradigm

Abstract: This paper presents an "information-based representation paradigm". The objectives of this modelling paradigm are based on the premise that: Process is inseparable from the product; Information is collected and captured from the very early stages in the procurement process, including the design brief (program). Many early decisions and design intentions must be captured and made known to the future managers of the facility; It is imperative that we addresses the issues of buildability and building quality (performance and its measurement); A building is considered as an organic growth process: information thus grows as the product develops from its embryonic stages, to full growth, to adaptive re-use, and to decay; and Information modelling is 'continuous' over the building life cycle: not piece-meal to address the various disparate requirements.

A dynamic framework for project decision the management of construction projects. support - developing "soft" interfaces for

Abstract: Construction is an information intensive industry involving many different participants (or actors). The fragmentation of functions and barriers to the effective communication of information from amongst participants has been a major obstacle to productivity and quality in the industry. The development of computer technology offers the technical means to improve the integration between different participants and functions. The paper describes a dynamic framework for project decision support which take into account the participants and the stages of the project life cycle. This conceptual framework has been adopted in formulating a strategic approach in managing project buildability, and is being extended into post occupancy functions. An essential part of the strategy is the development of user-oriented interfaces linking managers and decision makers to an arsenal of relevant technology which remains largely invisible. This approach emphasises the development of "soft" technology which takes into account management needs generated by the project process. Project participants and decisions makers are thus able to directly exploit the potential of computer- based integration of project information while maintaining their own specialist roles and functions.
