ABSTRACT
This chapter addresses the issue of the unreliability of workflow in the construction of complex, major projects and techniques for improving the stability, reliability, throughput and cost of work. The building and construction industry is extraordinarily diverse, so practices, processes and products vary widely across different sectors of the industry. The unreliability of promises for the completion of work has very significant repercussions on efficiency throughout the supply chain. Everyone who is operating under a fixed price agreement, and that is most parties in normal contractual situations, loses margin if their workers cannot work in a smooth, predictable and reliable manner. Construction is a risky activity in many ways: building contractors are particularly exposed to risk arising from poor weather. In addition, it is also an industry that has a history of poor safety and quality outcomes, and historically high levels of industrial unrest.
