Quality Control and Quality Assurance Plan for Bridge Channel-Stability Assessments in Massachusetts

by Gene W. Parker, U.S. Geological Survey, Marlborough, United States,
Harlow Pinson, U.S. Geological Survey, Marlborough, United States,



Document Type: Proceeding Paper

Part of: Hydraulic Engineering

Abstract:

A quality control and quality assurance plan has been implemented as part of the Massachusetts bridge scour and channel-stability assessment program. This program is being conducted by the U.S. Geological Survey, Massachusetts-Rhode Island District, in cooperation with the Massachusetts Highway Department. Project personnel training, data-integrity verification, and new data-management technologies are being utilized in the channel-stability assessment process to improve current data-collection and management techniques. An automated data-collection procedure has been implemented to standardize channel-stability assessments on a regular basis within the State. An object-oriented data structure and new image management tools are used to produce a data base enabling management of multiple data object classes. Data will be reviewed by assessors and data base managers before being merged into a master bridge-scour data base, which includes automated data-verification routines.
