Updated ASCE manhole guidelines focus on inspection, rehabilitation methods
(UI) — ASCE’s Manual of Practice, Manhole Inspection and Rehabilitation, Third Edition, MOP 92, provides a valuable update to reflect current and complete inspection, as well as grading protocol that offers logical step-by-step guidance for maintaining and improving the longevity of manhole systems.
This is a collaborative work 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.
Keys areas updated include:
- New chapter on wall thickness design for full-depth manhole rehabilitation,
- Information on standardization and NASSCO’s certification programs,
- Expanded content on various manhole rehabilitation methods and technologies, and
- New section detailing the importance of proper manhole inspection and rehabilitation.
MOP 92 is 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.
