A case study on the use of LED temporary construction lighting system Huang, Yi Jie; Lin, Ken-Yu; Angeley, Jeff
Adequate lighting is a necessity on construction sites not just for work completion, but also for the work quality, worker safety, and project productivity. This paper discusses the problems associated with traditional temporary lighting on construction sites and presents a case study on using LED temporary construction lighting as a potential solution. Various studies have shown that the traditional methods of providing temporary lighting are inadequate due to their non-compliance with OSHA requirements; visual discomfort; constant maintenance; and impacts to productivity, safety and health. On the other hand, studies have shown that using LED as a source of temporary construction lighting provides benefits over the traditional lighting system, even though such uses are still rare within the industry. Using LED for temporary construction lighting, however, is subject to the high initial materials cost and other drawbacks. To this end, the objective of the research is to provide a deeper understanding of LED temporary construction lighting and ascertain its benefits and limitations through a case study. The study involves the University of Washington’s Bothell Science and Academic Building Project. The study involves interviews with both the lighting system vendor and onsite project personnel; survey questionnaire distributed to the field workers; and cost analysis of the LED temporary lighting system. The case study concluded that the benefits of using LED temporary construction lighting outweighed its limitations, but the individual cost savings may belong to different parties and may not necessarily be passed on to the owner depending on the contractual arrangements.
