Value Engineering for the Crosstown Project Application of VE - The Crosstown Project 11/18/2011 17 Agenda VE Objective Best value at lowest cost. Application of VE 11/15/2011 18 2-Value Engineering for the Crosstown Project VE Objective In achieving best value at lowest cost, must: • Provide safe operation • Adhere to design requirements • Provide low life-cycle cost • Provide high performance -reliability - availability - maintainability • Be functional and aesthetically pleasing for customers. Application of VE 11/15/2011 19 2-Value Engineering for the Crosstown Project What is Value? Value Engineering – Traditionally perceived as a means to reduce costs. – Can also be applied to improve performance. – Measures to determine performance are specific to each VE Application of VE 11/15/2011 20 2-Value Engineering for the Crosstown Project How Achieve Objectives?
