Abstract/Summary
This paper investigates the cost and productivity impacts that a tower crane has on jobsite productivity. From reviewing recent literature, it is clear the stagnating labor productivity of the industry is a major problem. One way that has been proposed to solve this problem is through the implementation of more sophisticated equipment, for the sake of this paper that equipment is tower cranes. This paper performs an analysis of historical records of a mid-sized framing subcontractor located in central California. This company has recently ventured into the crane business which provided an excellent opportunity to collect data. Having just started with cranes the piece of equipment had not been priced into the companies estimates yet, allowing for a clean approach. The data came from estimates that had been completed using the company's standard labor productivity rate, and comparing that to the actual hours spent on that job. Additionally an analysis was made looking at the area of each job that was usable for storage of materials, comparing the area accessible by forklift versus the area accessible by crane. This paper aims to approximate standard cost savings in the form of labor hours caused by the presence of a tower crane.
