Life Cycle Measures of Cost Effectiveness for 4 D CAD in Design and Construct Projects across Industry Sectors. The effective and efficient delivery of complex construction projects will be transformed by the increased application of virtual design and construction technologies, including 4D CAD. By combining a 3D computer model of a design with the time dimension of the construction schedule, 4D CAD enables risks and opportunities to be better managed during the design phase and hence avoid co ....Life Cycle Measures of Cost Effectiveness for 4 D CAD in Design and Construct Projects across Industry Sectors. The effective and efficient delivery of complex construction projects will be transformed by the increased application of virtual design and construction technologies, including 4D CAD. By combining a 3D computer model of a design with the time dimension of the construction schedule, 4D CAD enables risks and opportunities to be better managed during the design phase and hence avoid costly issues during construction. However this requires addition design costs which currently represent a barrier to the uptake of this transforming technology. This project will overcome this by developing a flexible framework that allows the benefits gained across the life cycle of a project through using 4D CAD to be set against the additional costs and thus make this emerging technology more attractive to industry. Significantly this research will be based on comparative cases studies across different industry sectors including civil, building, and process engineering.Read moreRead less

New project delivery methods (e.g. design & construct; alliance contracting) in major commercial and infrastructure projects have the potential to dramatically increase the value added to clients and the wider community.
However to realise this potential, we need to better understand those socio-technical factors that foster an effective design management culture within traditional construction companies, especially their knowledge sharing culture.
This project will develop and test an innovative research methodology that blends approaches from the social sciences and engineering. The findings regarding design management will have wide applicability to industry and cover civil, building, mining and process engineering projects, each of which has its own culture.Read moreRead less

The effect of tunelling on existing rock bolts. As more underground facilities such as rail, road, sewerage and service tunnels are constructed in our major cities, more and more frequently new tunnels have to cross over or run alongside existing tunnels. As the roofs of tunnels are generally supported by rock bolts and lined with shotcrete, the support system can be damaged by the rock movements caused by the excavation of the new tunnel. Little research has been carried out on this problem, an ....The effect of tunelling on existing rock bolts. As more underground facilities such as rail, road, sewerage and service tunnels are constructed in our major cities, more and more frequently new tunnels have to cross over or run alongside existing tunnels. As the roofs of tunnels are generally supported by rock bolts and lined with shotcrete, the support system can be damaged by the rock movements caused by the excavation of the new tunnel. Little research has been carried out on this problem, and so often expensive deviations have to be made to tunnels to avoid going near existing ones. The proposed research will provide numerical tools to allow prediction of loads induced into rock bolts by nearby tunnels, leading to more economical and safer tunnel design.
