摘要

In the summer of 2012, John Struzz-iery, principal engineer at Kleinfelder/ SEA, was faced with a challenge: a tailing 12-in.VCP sanitary sewer located on Terminal Road in Cambridge, Mass. The section had recently been CCTV-inspected using the Pipeline Assessment Certification Program (PACP) and numerous condition grade 5 defects were found. The pipe segment was literally collapsing as pieces of pipe were dropping into the invert.
