This document discusses what is needed to implement performance-based design (PBD). It identifies key stakeholders that must be understood, including the public, developers, architects, officials, and engineers. It also stresses the importance of building awareness among these groups and understanding the PBD process and roles of those involved. The document argues that PBD can achieve the same or better performance at lower cost through innovation and refined designs. It provides tips on convincing clients and architects to adopt PBD, such as improved communication, demonstrating benefits, and creating consistent messaging around PBD.

The general belief Increased Performance → Increased Cost Increased performance can be achieved for same cost Reduced cost for same performance Improved/efficient designs Need not be true Easy Needs Knowledge, innovation, better tools, better technology, critical thinking, out-of-the-box solutions Cost and Performance
- 10. Designing Economical Structures Economical design requires conscious effort Both CBD and PBD can lead to economical design PBD provides a greater opportunity to refine and economize with confidence
- 11. Designing Economical Structures The 4 Rs of economical and high performance concrete buildings 1. Right type of structural system 2. Right member types and sizes at the right places 3. Right amount of reinforcement in right members 4. Right detailing of right reinforcement
- 12. Convincing Clients and Architects Improve presentation and communication skills ◦ Animations, graphics, videos, Show them how PBD benefits them ◦ Cost, safety, image, salability, advancement, high end… Scare them a bit, if they don’t do it ! ◦ Disaster maps, pictures, exaggerated animations, Create Unified and Consistent Messaging ! << ASEP>>
