Abstract

Despite of the advances in construction planning and scheduling software, construction managers and planners are still facing problems in achieving accurate planning, scheduling and costing due to the one-off nature of the construction projects and the inherently uncertain site conditions and soil characteristics. The aim of the research presented in this paper is to introduce a new methodology for integration of ‘variable producti¬vity’ data with a visualisation model of earthwork operations. To achieve this aim, a number of objectives have been set: identification of current industrial practices and confirming the needs and aspirations of the industry, designing of a methodology and a model to integrated variable productivity with visualisation, and performing a case study to demonstrate and verify the model. The paper presents a prototype of a 4D visualisation model which is designed by integrating the road design data, quantities of cut and fill, productivity model, algorithms for modelling terrain surfaces and a progress profile visualiser. The model generates automatically terrain sur¬faces of progress profiles for earthwork operations and visualises progress profiles throughout the construction operations under different site and soil conditions. It is demonstrated with a real life case study in a road pro¬ject. The paper concludes that the model should be able to assist in producing efficient construction scheduling and resource planning, thereby reducing production cost and improving on-site productivity.
