Abstract
Collection of historical data must be a systematic method of categorizing the information using a standard structure referred to as a code of accounts. Before you can effectively collect and analyze historical data, you must have a coding system in place. The job cost by cost code and type is used to describe the task and cost type to describe the man-hours associated with the task. After historical data has been collected, it must be verified by graphic and statistical analysis. This chapter will enable the estimator to collect, verify, and analyze historical data to develop man-hour tables that can be used to set up and implement a man-hour database system using comparable cost and man-hour data to estimate future projects.
