The delivery of transportation infrastructure has transitioned from method to performance-based specifications. Method specifications relied on owner expertise to dictate the materials, equipment and methods to be used by a contractor to produce the product desired by the agency. In the late 1980s, agencies began to endorse end result specifications. Parameters outside of the specified ranges could result in financial penalties or a requirement to remove and replace installed product.
Agencies are moving beyond quality assurance specifications that specify end product quality to Performance-Related Specifications (PRS) that specify quality in terms of desired performance over the long term. PRS is helping agencies build better, longer-lasting roads and build them more cost-effectively.
Construction quality characteristics, such as smoothness, pavement thickness, air voids, and concrete strength, have been found to correlate with fundamental engineering properties that can predict performance. Performance related specifications describe the desired levels of these, or other, key quality characteristics and uses models to predict pavement performance.
One of the major benefits of PRS is the ability of a contractor to be innovative in achieving the PRS objectives. They can use PRS to improve their products and methods to meet the agency objectives without the need for approval of their means and methods.
This webinar outlines the progression of agency specifications and provides an overview of the steps necessary to adopt PRS. Examples of various types of contracts incorporating PRS as provide along with lessons learned in their adoption
The learning objectives of this webinar include:
- Understand the evolution of specification systems
- Identify the key components necessary to develop specification systems
- Recognize the value of performance specifications
- Avoid early age deterioration or failure of pavement assets
- Understand the connection between performance specifications and transportation asset management
Instructor: David K. Hein, P.Eng.
David Hein is a consulting Civil Engineer with over 35 years of experience in the design, evaluation and management of pavement infrastructure. He recently retired from Applied Research Associates, Inc. of Toronto, Ontario. He is the past president of the American Society of Civil Engineers Transportation and Development Institute, long term member of the Transportation Association of Canada and has represented Canada on the World Road Association pavements and asset management committees since 2002. He has been involved in numerous national and international projects including many of the public/private/ partnership highway construction projects across Canada and the United States. Mr. Hein has completed numerous pavement design, evaluation and management projects throughout British Columbia including both design and management of the Sea to Sky Highway and is a regular instructor completing specialty design, construction and maintenance courses for the British Columbia Ministry of Transportation.

- Webcam – in order to engage and collaborate, participants will be expected to have their webcams on for the duration of the class
- Internet connection - For best results, you will want to ensure you have an internet connection with an upload/download speed of 3-5 Mbps. You can test your internet speed here. Minimum recommended speed is 1.5 Mbps, but anything below 3 Mbps may result in loss of quality or buffering. Ideally hardwired connection versus wireless for stability - connect your computer directly to your router using an ethernet cable, rather than using your home wi-fi.
- A quiet space with minimal distractions - microphone will be engaged for interactive sessions. Please plan to be fully engaged in the class and clear your work schedule just as you would for the in-class program.
- Comfortable chair
