This article explores the concept of practical design (PD) and its manifestation at the Washington State Department of Transportation (WSDOT). It focuses on the value engineering approach as a tool for PD and discusses opportunities and choices in achieving desired conditions. The article also highlights the importance of context and performance-based design in transportation projects.

1 Practical Design
PRACTICAL : relating to what is real (rather than possible or imagined) : likely to succeed(reasonable to do) : appropriate or suited for actual use real What do you think it means to be practical?
DESIGN : to plan and make decisions (for something to be built or created) : to plan and make (something) for a specific use or purpose define design
The Federal Highway Administration, defines Value Engineering so that a solution… “…provides the needed functions, reliably, at the lowest overall cost."
Practical Design is… • an approach decision-making. • focused on project need. • finding the lowest cost solutions.
Why Practical Design? Why Now? Haven’twe always been practical? How can we be more practical?
FOCUS Problem Statement (NEED) • Demand Management • Systems Management (ops) • Capital project • Multimodal • Sustainable • Collaborative

Context within Practical Design Practical Design Policy What’s Changing and How? Example: New Jersey and Pennsylvania Context Classification System From: Smart Transportation Guidebook; PennDOT and NJDOT. From: Smart Transportation Guidebook; PennDOT and NJDOT.
Designing for All Users • Bikes • Pedestrians • Transit • Maintenance operations How you design for different users depends on context. 17

3 Value Engineering as a tool for Practical Design
A Value Study is…. “the formal application of a value methodology to a project in order toimprove its value...” VALUE STANDARD and BODY OF KNOWLEDGE V = F/$ Practical Design is …. “The least cost options to solve today’s needs” V = F/$ Lowest Cost Solution.
