Factors Influencing Clients’ Commitment to Sustainable Construction Practices

Abstract

The success of every construction projects largely depends on the level of commitment of the clients. This study examined the factors influencing the level of clients’ commitment to sustainable construction practices in Nigeria. A questionnaire survey was use to collect data from the public and private construction clients on the level of influence of 16 factors extracted from the literature. A total of 182 valid questionnaires were used for analysis. The result revealed that nine factors with weighted average (W) 0.8≤W≤1 have a high level of influence, whereas seven factors with 0.6≤W≤0.8 have a high-medium level of influence on the clients’ commitment. However, the five most influential factors were: client knowledge and awareness, Cost implication and mechanism of financial involvement, economic value and return on investment, end-user/client perception and preference, and health and safety implications. The result further revealed that there is significant difference on how these factors influence the level of commitment of sustainable construction practices of the public and private clients. The study suggested that the disparity was due to the differences in the level of knowledge, awareness, involvement and commitment of the public and private clients to sustainable construction concept. Hence, it is important to optimize the level of knowledge and awareness of the clients, about the cost, benefits/profits, and health and safety implications of sustainable construction practices so as to promote the level of client’s commitment to sustainable construction practices. It recommended for adequate client involvement throughout the sustainable construction life cycle and a sustained awareness campaign, championed by relevant government agencies and professional organizations through different public programs so as to increase the clients’ commitment and desirability to demand for more sustainable construction projects.

Safety Risk Evaluation of Construction Site Based on Unascertained Measure and Analytic Hierarchy Process

“…Besides, the seasonal workers, temporary workers, and labor personnel in the construction team occupy a considerable proportion, so the mobility of the construction team is significantly higher than that of other industries. (3) ere are many open-air and high-altitude operations in construction, and the working conditions are poor. e construction team works outdoors for a long time, accounting for about 70% of the work in the open air during the whole construction process.…”

“…Because the construction project has the characteristics of high management difficulty, long cycle, large personnel mobility, large scale, complex technology, and so on, especially, it has many uncertain factors in the construction process, so there is a greater risk than the general product production [3][4][5]. Especially, the modern construction projects driven by urbanization, their technical complexity, construction scale, resource consumption, and capital input are much larger than the previous construction projects, and the risks of the project in the process of operation have increased a lot than the previous construction projects [6][7][8].…”

Evaluating the Interrelationships Among Key Stakeholders’ Performance in Achieving Project Success

“…The role of the owner includes specifying criteria, building requirements, material specifications, reviewing documents, determining project cost, giving approval, making payments, defining the completion date, etc. The owner has a vital role in the project's success [21].…”

Contracts’ Performance Measurement in Czech Construction Companies

“…The measurement of hazardous processes [8] and the evaluation of the number of accidents on site made it possible to improve safety measures and increase compliance with them. Recently, where there has been more emphasis placed on sustainable economy and environmentally sound behaviour [9], criteria from the area of environmentally responsible management have become gradually implemented in contemporary construction contract measurement systems. The amount of waste produced, the amount of recyclable waste used on site, water management and greenhouse gas emissions are measured.…”
