A new online course available from the Federal Highway Administration's (FHWA) National Highway Institute (NHI) provides participants with an introduction to statistical analysis and the development of statistically valid quality assurance (QA) specifications for highway construction projects. By using statistically valid QA specifications, agencies can obtain a more uniform product, better link project payment to the product received, and reward contractors for quality. The free 8-hour course, SpecRisk Quality Assurance Specification Development and Validation (Course No. FHWA-NHI-134070), also introduces SpecRisk, a new software program available from FHWA that enables users to successfully develop statistically valid specifications. Participants will have the opportunity to download SpecRisk for future use.
Upon completion of the course, participants will be able to:
The course requires a solid foundation in basic statistics. Prior completion of the NHI course, Materials Control and Acceptance—Quality Assurance (Course No. FHWA-NHI-134042), is also recommended.
Quality Assurance Training
NHI, in partnership with FHWA's Office of Infrastructure and Resource Center, offers a suite of QA training courses and workshops to meet the needs of State and local transportation agencies and industry. The goal is to emphasize the importance of implementing a QA program, as well as to standardize QA practices across the country. "The training courses are geared toward different levels of expertise, covering everyone from construction personnel to staff who develop specifications," says Mike Rafalowski of FHWA. In addition to the new SpecRisk course, the following training is now available:
Also under development is a course on QA Specification Development and Validation.
In addition to the NHI courses, the FHWA Resource Center is offering a 1-day workshop, Introduction to Percent Within Limits: The Quality Measure of Choice. The workshop provides participants with an overview of quality measures, details on how to use percent within limits (PWL), and specifics on computing PWL. Hands-on exercises provide participants with the opportunity to compare and contrast quality measures and compute PWL for sample materials data. The workshop is offered at no cost to the host agency. For more information on scheduling the workshop, contact Dennis Dvorak at the FHWA Resource Center, 708-283-3542 (email: email@example.com).

The SpecRisk course is designed for Federal, State, and local highway agency engineers in the areas of materials, construction, and research who are developing statistical specifications. The training is also appropriate for industry personnel who are involved in reviewing and providing input to the specification development process.

"The Michigan Department of Transportation and FHWA's Michigan Division office are looking forward to using SpecRisk when we begin reevaluating the concrete pavement acceptance program in Michigan this spring. The online training was easy to follow, and the downloadable presentations will be useful as a reference once we begin the risk analysis," says Robert Conway of FHWA's Michigan Division office.
