Prepared by the Manhole Inspection and Rehabilitation Task Committee of the Pipelines Infrastructure Committee of the Pipeline Division of the Utility Engineering and Surveying Institute of ASCE in partnership with the Manhole Rehabilitation Committee of NASSCO
Manhole Inspection and Rehabilitation, MOP 92, Third Edition, provides a valuable update to the Manual of Practice to reflect current practices in both the inspection and rehabilitation of manholes.
Updated topics include
- A new chapter on wall thickness design for full-depth manhole rehabilitation,
- An expanded chapter on the importance of manhole condition assessment standardization through NASSCO’s Manhole Assessment Certification Program (MACP) and proper inspection through NASSCO’s Inspector Training Certification Program (ITCP) for manhole rehabilitation,
- An expanded chapter on various manhole rehabilitation methods and technologies, and
- A newly added summary chapter, detailing the importance of proper manhole inspection and rehabilitation.
MOP 92 continues to be a valuable trenchless technology resource, assisting agencies in the proper identification of inventory and asset management, assessment and condition of manhole structures, decision-making regarding rehabilitation materials and methods, as well as providing key quality control measures when specifying the use of rehabilitation materials and technologies for manholes.
