Download Evaluation of State Quality Assurance Program Effectiveness Book in PDF, ePub and Kindle
In early 2008, the Federal Highway Administration issued a task order under the Advanced Quality Systems Indefinite Delivery/Indefinite Quantity Contract for a contractor to quantify the effectiveness of State quality assurance (QA) programs. The objective of the study was to develop, apply, and make recommendations for the use of a procedure that transportation departments could use to quantify and improve the effectiveness of existing quality assurance programs. Based on the knowledge and experience of the research team, four State highway agencies (SHAs) were chosen to participate. An introductory project meeting was held in December 2008, but due to personnel problems, only three agencies participated. The goal of the meeting was to discuss the objectives and scope of the project with State representatives and request their input. The three SHAs agreed to provide QA data from construction projects in their State for the team to analyze. Because sufficient data were not available to accomplish the original task, the scope was modified to use an analysis of acceptance procedures included in the agencies' specifications instead of using actual QA data. In summary, four SHA construction specifications were selected for analysis from three SHAs, two for hot mix asphalt (HMA) pavements and two for portland cement concrete (PCC) pavements. The study shows that either the computer program SPECRISK or computer simulation can be used to analyze the statistical risks of most, if not all, specifications. Both HMA pavement specifications and one of the PCC pavement specifications were amenable to analysis by SPECRISK because they are based on percent within limits as the statistical quality measure. The remaining PCC pavement specification was based on averages and had to be analyzed by computer simulation. Probabilistic Optimization for Profit (Prob. O. Prof) was one of the software programs anticipated to be useful in the analysis. However, it required data that were not available and thus could not be used in the analyses. The report includes analysis of the specifications, particularly the risks involved and recommendations for improving areas that are considered unclear or statistically invalid.

Download Quality Assurance in Materials and Construction Book in PDF, ePub and Kindle
"This review is a product of the FHWA 2006, National Review Program (NRP). Quality Assurance (QA) was selected for review in 2006 because the program was ranked as one of the top five areas of interest for review by FHWA. Over the last 10 years an average of 75 percent of the Federal-aid program was affected by the QA program. The goals of this review are: to reduce risk in the quality assurance program; recommend improvements which allow Division Offices to evaluate, approve, and monitor State quality assurance programs with a high degree of confidence; and identify successful practices that will add value to this program at a national level."--Page ii.

Download State DOT Management Techniques for Materials and Construction Acceptance Book in PDF, ePub and Kindle
This synthesis will be of interest to state Department of Transportation (DOT) materials and construction engineers; contract, procedure, and specification specialists; construction personnel managers; researchers; and private consultants. The synthesis describes the current state of the practice of state DOT management techniques for materials and construction acceptance, including approaches to inspection and testing. The associated requirements for maintaining adequate qualified personnel to operate the acceptance and testing programs are considered in the information reported. The information was collected by surveying state DOTs and by conducting a literature search. This report of the Transportation Research Board presents background information on the changing role of specifications, quality assurance processes, warranties, material certifications, and personnel management regarding the state of the practice for state DOT management techniques for materials and construction acceptance. In addition, detailed information is presented on personnel issues. The details of materials test methods and statistical quality control procedures are not included in the report. However, discussion of these technical aspects of materials and construction acceptance are included on the basis of their influence on personnel training requirements, and changes in administrative requirements.

TRB’s National Cooperative Highway Research Program (NCHRP) Research Report 838: Guidelines for Optimizing the Risk and Cost of Materials QA Programs proposes guidelines for optimizing the risk and cost of materials quality assurance (QA) programs. It develops a methodology for establishing a materials QA program that optimizes risk and cost by providing appropriate types, levels, and frequencies of agency testing and inspection for transportation projects across their full range of type, size, complexity, and project-delivery method.

Download Construction Inspection Handbook Book in PDF, ePub and Kindle
In addition to quality control (QC), this book introduces the concept of quality assurance (QA). Quality assurance has a number of definitions, but in general is the combination of the quality assurance plan with procedures through which the quality control inspector can inspect in the field. The book is arranged in categories so that is can be used in handbook fashion; each section stands independent of the others. The arrangement of the major portion of the book is organized in the same format as we usually find in building construction specification, the Construction Specifications Institute (CSI) format.

Download The Development of a Contract Quality Assurance Program Within the Virginia Department of Highways Book in PDF, ePub and Kindle
In order to assure the quality of construction products and processes, the Virginia Department of Transportation has established three levels of construction control. First, contractors themselves provide oversight and quality control as set out in the Department's Road and Bridge specifications and in their contract stipulations. Second, the Department's construction inspectors provide quality acceptance in that they determine whether contractors are adhering to specifications and either accept or reject the work in progress. Finally, the Department's quality assurance program examines the methods for inspecting projects and determines where new procedures are necessary to keep the construction process under departmental control. In 1987, the quality assurance effort for highway construction In Virginia was redesigned and retitled the Contract Quality Assurance Program, and steps were taken to put the program on a sound statistical footing and to improve its reliability among field personnel. Sample size requirements were calculated, and a stratified random sampling plan was instituted. A list of inspectable items was developed and prioritized to assist inspectors in managing their time and to ensure agreement on what field inspection entailed. New reporting procedures were developed to change the focus of the program from "inspecting inspectors" to evaluating the inspection process, thus removing the punitive aspects of the previous program.

Download Key Elements of Construction Quality Assurance for Implementation Book in PDF, ePub and Kindle
TRB’s Technical Activities Division has released Transportation Research Circular E-C249: Key Elements of Construction Quality Assurance for Implementation, presenting a synopsis of "Quality Assurance: There’s Value in the Basics," held at the 2018 Annual Meeting of the Transportation Research Board. In this session, four speakers with a range of perspectives—the Federal Highway Administration (FHWA), state transportation agencies, and a contractor—presented on key elements and best practices for implementation of an effective quality assurance program. The details of implementing quality assurance can get complex depending on an agency’s needs and practices. However, there are some basics, core elements, and best practices that can and should be followed to keep the focus on the ultimate goal of producing, delivering, and accepting quality products for infrastructure construction.
