Abstract: This paper develops a platform that can be used to determine how to effectively and efficiently deal with a large number of temporary facilities under a constrained site condition(s). The ultimate goal is to reduce the material handling costs between transformation phases of construction works occurring during the project's development period. Empirical and deductive research is first adopted to mathematical model dynamic site layout planning using the branch and bond algorithm (B& B). Second, a real-life construction project is examined to illustrate how dynamic site layout planning (using the aforementioned B& B algorithm and a computer software program called LINGO) can reduce the material handling costs. The application of the proposed methodology is then showcased against a case study that utilizes a comparative analysis between the “dynamic” and “statistic” site planning approaches. By iding the construction period into different phases, the developed model is shown to be capable of optimizing the material handling costs between the phases of transformation during construction works. Optimal costs are also considered using the site boundary and unit cost for moving construction materials between two facilities. The comparative analysis results illustrate that the B& B algorithm reduces material handling costs by 33%. The proposed model offers an effective planning algorithm for the site layout and location of temporary facilities. More specifically, it can make a substantial improvement in reducing the travel time and material handling cost between the temporary facilities in the construction sites. The primary knowledge contribution of this study to the site layout is successfully deal with the unequal area problem of temporary site facilities and incorporates the concept of dynamics site planning into the algorithm.

Abstract: The construction industry in developed economies is suffering from a shortage of workers, triggering project cost escalations and project delays and suppressing the whole economy. This paper aims to explore the perceptions of the general public and construction workers towards workforce shortages in the Hong Kong construction industry and identifies the critical factors affecting their intention to join the industry. The triangulation approach was adopted in this study and a street survey was conducted in grass-roots areas in Hong Kong. The questionnaire was formatted using a five-point Likert scale and semi-structured interviews with ten experienced workers were used to validate and interpret the results from the street survey results. The triangulation approach found that ‘harsh working conditions’, ‘job instability’ and ‘lack of career prospects’ are the primary barriers dissuading the public to join the construction industry. This paper provides insights into the critical factors affecting the construction workforce supply and identifies possible solutions for maintaining a sufficient workforce.
