An alternative heuristic method for scheduling repetitive projects in which resources are limited and activities may be executed with multiple modes of resource demands associated with different durations is proposed. Unlike general heuristic methods that separately analyze each competing...

The quantity of some resources is limited because of project cost constraints. These resources may be required by multiple activities simultaneously during a construction process. In a discrete simulation that models the construction process, tracing and controlling such entities, e.g....

This study investigates the relationship between the characteristics of construction personnel and their degree of recognition of safety signs and symbols. The safety signs and symbols are split into categories of mandatory action signs, prohibition signs and warning symbols. Thirty safety signs...

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...

With mandatory implementation of the ISO 9000 quality system by the Housing Authority in Hong Kong, most construction firms there now claim to have initiated quality systems in their processes as defined in their quality manuals. In addition, an objective quality measuring yardstick, the...

The whole construction industry (contractors, consultants and suppliers) is suffering from business shrinking under the prevailing deflationary economy in Hong Kong. Local contractors are facing tremendous financial problems. The financial situation of a typical local contractor has been...

This research describes a study of safety attitudes, practices and characteristics of construction firms in Hong Kong and their relationship to safety performance on construction sites. Forty-five construction companies are compared and studied. Each adopts different safety management...

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 significant proportion of building investment expenditure goes to replacement expenditure for organizations owning a large building stock or portfolio. Over the years, researchers have attempted to develop asset replacement models to aid decision-making in building portfolio management, based...

Material transportation for high-rise building construction relies heavily on tower cranes. Hence the proper use of tower cranes is of paramount importance for high-rise residential building construction. In planning and monitoring crane usage in Hong Kong, a schedule is usually prepared to...
