Process information modelling for public housing construction project in Hong Kong

摘要

Public building construction, which consists of many sub-tasks and numerous systematised working processes such as planning, mobilisation, scheduling, procurement and controlling, is complicated. If the project team is incapable of managing these processes seamlessly, it may result in severe project delay and cost overrun. This issue becomes even more apparent when utilising construction robotics, since precise process and scheduling information as well as feedback is required to ensure each task is completed correctly and on time. Support in addressing these complex management activities in particular for the robotic usage offers Process Information Modelling (PIM). In this paper the process-oriented modelling approach, PIM, which provides a collaborative way of planning, designing, producing, assembling and entire project life cycle management strategy is introduced. The main objective of PIM is to integrate with the conventional Building Information Models (BIM) and supplement them with a process oriented database platform, allowing for smooth data transfer, as well as promoting seamless and constant data sharing among all stakeholders. Digital documentation, simulation and real-time data are produced progressively to support the decisionmaking process. The effectiveness of the PIM is demonstrated on faade painting task by a painting robot for an on-going consultancy project commissioned by the construction industry council (CIC) in Hong Kong. The impacts of PIM on supporting the potential future applications of construction robotics and instigating the next construction information evolution are discussed.
