Concrete formwork is a common type of temporary structure used on construction projects. Because of difficulties in considering actual construction site implications during formwork design, assessments of formwork integrity often are made in the field by site personnel based on subjective visual inspection. Further, the construction and placement of concrete formwork continues to be a high-risk activity, especially in regard to fall injuries and fatalities. This paper presents a research study in which work and material flow for the typical formwork construction process are mapped and the risks associated with each stage of the process are characterized to investigate the effects of construction site conditions and operations on concrete formwork. Development of the process and identification of the risks were based on interviews of construction site personnel involved in formwork construction and on jobsite observations of formwork construction activities. Throughout its life cycle, formwork is exposed to repeated loadings from concrete pressure, worker activities, and environmental conditions. The mapped work flow provides new information that can be used for the design and construction of formwork to improve construction worker safety and production, and study the reliability of formwork with respect to repeated operational and environmental loading.
