AASHTO's Trns*port Estimator file last modified on: 4/6/2010

Trns*port Estimator is an interactive, PC based, stand-alone cost estimation system for highway construction. It utilizes a Windows graphical user interface (GUI) for the preparation of detailed estimates. Estimator supports estimation via cost-based and historical techniques.

Maryland State Highway Administration (SHA) has adopted "Estimator" software (developed by InfoTech, Inc) for submission of estimates to this administration. Any consultants interested in purchasing this software may order it directly from:

Phone: (352)381-4400 FAX: (352)381-4444

A Training Manual, User Manual, and other documentation comes with Estimator software. A copy of Maryland's SHA guide, SHA Estimator User Manual can be found on this page.
