MII is the second generation of the Micro-Computer Aided Cost Estimating System (MCACES). 

It is a detailed cost estimating software application that was developed in conjunction with Project Time & Cost, Inc. (PT&C).  MII is one of several modules of an integrated suite of cost engineering tools called Tri-Service Automated Cost Engineering Systems (TRACES).   It interfaces with other PC based support modules and databases used by the Tri-Service Cost Engineering community.

MII provides an integrated cost estimating system (software and databases) that meets the U.S. Army Corps of Engineers (USACE) requirements for preparing cost estimates.  Now being used by many of the USACE districts, it will soon be a requirement for all USACE districts to use MII, as well as all architect-engineering (A-E) firms performing design work for the USACE.
