Concrete precast plants require strict control over and adherence to the timing and
sequence of operations. Variation for this research is divided into the variation in task …

In this research, variation is defined as the time difference between what was planned and
what actually happened in terms of task starting times and duration. Variation in construction …

Improving productivity and reducing work-in-process are two activities that can improve
project performance, but are often difficult to accomplish. The construction process is …

Variation in production is a major cause of producing waste in onsite construction
operations, resulting in a workflow that is full of delays and interruptions. To reduce the …

Precast concrete structures (PCs) are widely used in the construction industry to reduce
project delivery times and improve quality. On-time delivery of PCs is critical for successful …

In the initial steps of construction projects, contractors plan the construction processes and
timetables as accurately as possible; however, a number of change orders are inevitable. It …

Due to the inherent nature of the construction industry, all construction projects have some
amount and type of uncertainty. This uncertainty can lead to variation in project task …

Variation, defined for this research as the time difference between what was planned and
what actually happened, is important as it can affect the productivity performance of …

This paper reports the methods and initial findings of an empirical study of fabrication lead
time and demand variability conducted with a precast concrete fabricator. The study is the …

Activity production rates drive the development and accuracy of linear schedules. The nature
of linear projects dictates an assortment of variables that affect each activity's production …
