The Village of Mount Prospect, IL Public Works Department retained Mercury to conduct optimal replacement cycle analyses for seven key types of vehicles and pieces of equipment in the Village’s fleet. The objective of these analyses was to determine the age or accumulated usage (e.g., mileage) level at which each types of assets should be replaced in order to minimize its total cost of ownership. This project was a follow up to an alternative fuel vehicle feasibility study Mercury conducted for the Village in early 2015.
