New (PRET) Production Rate Estimation Tool
A new tool is available for designers to more accurately calculate contract time. The tool is an Excel program called PRET (“Production Rate Estimation Tool”). PRET can help the user determine production rates based on a variety of project attributes. The tool uses information extracted from past projects through daily work reports logged in SiteManager/AASHTOWare. This tool is a useful source for determining production rates on a project-specific level. Production rates generated from PRET can be entered into the Contract Time Calculation (CTC) spreadsheet.
The PRET Manual and the PRET spreadsheet along with the updated CTC guide and the CTC spreadsheet can be found on the Contract Time Calculation web page.
The PRET, CTC and Adjustment Factors worksheet updates, and this notification are a collaborative effort between MDT Preconstruction, Construction, and Engineering Operations. Information on the research project resulting in the development of this tool can be found on the Research Projects web page - Effective Production Rate Estimation and Activity Sequencing Logics Using Daily Work Report Data: Phases 1 and 2.
