Site layout planning is a complicated issue due to the existence of a vast number of trades and inter-related planning constraints. In this paper, artificial neural networks are used to model the non-linear operations of a key site facility: a tower crane — for high-rise public housing...

A good formwork system enables speedy completion of the concrete structure, following which other subsequent trades can be started. However, the current intuitive judgment approach in the selection of formwork systems cannot assure an optimal and consistent result. Artificial neural networks may...

A number of procurement selection systems have been developed over the last decade. The use of multi-attribute decision analysis has been considered the foremost technique for examining client needs and the weightings of preferences from experts for each procurement system in the most objective...

The construction industry of Hong Kong has a very poor site safety record. The overall accident rate has gone down a little during the last few years, but the number of fatalities has risen dramatically. In the past, the Hong Kong Government adopted a laissez-faire approach in managing...

There are numerous construction safety measures adopted by the local construction industry in Hong Kong. The purpose of this study is to distil the more significant measures from all these practices. To achieve this, the rough set theory, a data mining technique by applying the rule induction...

In earthmoving operations, there are a number of activities that need to be considered; for example, path identification, plant selection, assessing the compatibility of the paths and the plants so selected, cost and productivity comparison of alternatives, safety and environmental considerations,...

Purpose: With the increasing interest in Public Private Partnership (PPP) there is a need to investigate the factors contributing to successful delivery of PPP projects. Design/methodology/approach: An empirical questionnaire survey was conducted in Hong Kong and Australia. The survey...

Abstract: Purpose – Several major infrastructure projects in the Hong Kong Special Administrative Region (HKSAR) have been delivered by the build-operate-transfer (BOT) model since the 1960s. Although the benefits of using BOT have been reported abundantly in the contemporary literature, some...
