Abstract: The software was a direct outcome of the collaborative EPSRC 'Virtual Construction Site - VirCon' project involving UCL, UMIST, Teesside and Wolverhampton Universities and several industrial collaborators. The software provides a platform for current research and knowledge transfer activities through the West Midlands Centre for Construction Excellence and has directly informed the development of the '3-Centre' collaborative visualisation system which provides support to numerous construction companies.

The main objective of this study is to test the hypothesis that both the resolution of the gridded-data set and the characteristics of the terrain being modeled have an effect on the accuracy of any derived data. To test this hypothesis, the terrain was classified in terms of its roughness. Various forms of data were derived from the terrain model; these include volumes, surface area, contours, and cross sections. The accuracy for each of these quantities was calculated by comparing them with values obtained from a control model. This research concluded that by both increasing the resolution of the regular gridded-data sets and varying the characeristics of the terrain, the accuracy of any derived data is affected. Description: This work was undertaken in collaboration with WS Atkins Consulting Engineers.

However, the awareness of corresponding responsibilities and the intuitive management of relevant knowledge continue to pose the greatest challenges to the duty holders in terms of implementing the Regulations. Within the context of established learning styles and teaching techniques, an integrated problem-based and collaborative learning approach is being adopted in the delivery of a series of special construction health and safety short courses for construction professionals. The programmes are attended by an average of ten participants with varied construction related backgrounds on each of the iterations. Starting from the theoretical framework of the Regulation requirements, the approach evolves into contextualised problem solving in respect of each of the stages of the construction process. Well defined pre-selected problem solving tasks and background related problem solving tasks are collectively applied to facilitate efficient and effective knowledge transfer and acquisition. A collaborative learning approach was finally applied to elicit peer knowledge thereby enriching participants’ individual knowledge base of the generic issues. Participant feedback suggests that the programmes have been successful in achieving their main aim of enabling awareness and improving the health and safety knowledge and management skills of the practitioners. Further work is envisaged in extensively reviewing other learning approaches and developing the more reasonable integrated approach to reflect changes in relevant legislation and the diversified experience of the practitioners who attend the programme.

Commercial 4D CAD applications are becoming more accessible and the use of this technology allows the construction planner to produce more rigorous schedules. A review of the technical competencies of these packages highlights that most of the commercially available packages concentrate on the use of 4D CAD simulations for aesthetic visualization purposes. Very few packages offer the ability to carry out analytical tasks on the developed simulation and this is often left to the interpretation of the user. A thorough appraisal of emerging research developments in 4D planning highlights that this technology is employed for various applications; however, the amount of detail required in a 4D simulation is still ambiguous. A model is proposed to determine the attributes required for use with each of the various applications of 4D CAD simulations. Finally, various lines of future research are highlighted, including the need for improved use of data exchange standards and the automation of linking the construction tasks to the 3D CAD model. Description: As a result of the reported work a 4D-modelling course was created and disseminated to the construction industry via a £1M training grant from the European Social Fund.
