BRIDGE EXPERTS COUNT ON NDT BUT SEE PROBLEMS

AT A RECENT FORUM ON NON-DESTRUCTIVE TESTING HELD IN NEW YORK IN JUNE, SPEAKERS EMPHASIZED THE GROWING OPPORTUNITIES FOR NDT IN BRIDGE MAINTENANCE AND CONSTRUCTION. THEY ALSO MENTIONED SOME OF THE PROBLEM AREAS IN WHICH GREATER EFFORT IS NEEDED. THESE INCLUDE A CRITICAL NEED FOR QUALIFIED TESTING PERSONNEL AND THE NEED FOR UPDATED COMMON INSPECTION STANDARDS. AMONG THE PROBLEMS CITED WERE: (1) TESTING CRITERIA NEED TO BE BETTER ESTABLISHED, (2) TECHNOLOGY IS OUTPACING THE SUPPLY OF INSPECTION TALENT, (3) TESTING SPECIFICATIONS NEED REWRITING TO KEEP PACE WITH TECHNOLOGICAL DEVELOPMENTS WHICH MEAN PRODUCT AND MATERIAL IMPROVEMENT, (4) GREATER RAPPORT IS NEEDED BETWEEN FABRICATOR AND CUSTOMER AND ALSO BETWEEN DESIGNER AND ENGINEER. RADIOGRAPHY WAS CALLED THE WORKHORSE OF THE BRIDGE INDUSTRY. OTHER NDT METHODS IN GENERAL USE IN MOST STATES ARE VISUAL PROCEDURES, DYE PENETRANTS, MAGNETIC PARTICLE TESTING AND ULTRASONICS. /AUTHOR/
