Standard Practice for Job Productivity Measurement

Importancia y uso:

5.1 JPM produces two measurements: construction production rate and productivity.

5.1.1 JPM measures the overall production rate by comparing CPIP to the time elapsed in the construction schedule.

5.1.2 JPM measures overall job productivity through a comparison of labor usage to a reference point.

5.2 JPM issues early warning signals for construction.

5.2.1 JPM identifies productivity deviations in the form of any gains or losses in productivity, and anomalies indicating a special cause, from the productivity reference point.

5.2.2 JPM measures the productivity changes to individual building elements (according to the UNIFORMAT II format for organizing building data, in Classification E1557) with the same methodology used for overall job productivity measurement.

5.2.3 JPM measures ongoing changes in labor usage.

5.3 JPM measures productivity wherever the labor is used in construction by:

5.3.1 Any contractor or construction manager directly or indirectly responsible for the productivity of the labor and its usage.

5.3.2 Any contractor or construction manager conducting self performance on any portion of the construction job.

5.3.3 Any contractor or construction manager supervising labor performance on any portion of a construction job.
