Manhole Inspection and Rehabilitation, ASCE Manuals and Reports on Engineering Practice No. 92 (MOP 92), 3rd Edition

The American Society of Civil Engineers (ASCE) published its first manual of practice in 1992 to help the utility industry improve their manhole inventory. Since then, MOP 92 and been updated twice. The most current update is particularly helpful to anyone engaged or involved in manhole inspection, assessment, management, rehabilitation, renewal, or asset management. This particular edition, scheduled to be released as a final published manual, is much more robust and detailed (and helpful) than the prior to editions. This presentation will include an overview of the updates included in this 3rd edition (to be scheduled for release sometime in before March 2023, and highlight the information discussed in the chapters that have been updated. This presentation will also be a helpful one to anyone engaged or involved day-to-day operations, maintenance, and management of manhole structures in the following areas: Non-entry Manhole Inspection, Condition Assessment, Management, Rehabilitation and Renewal, Asset Management. The two prior editions of MOP-92 addressed manhole of the issues associated with inspection, scoring and prioritizing manhole structures. Under this newest edition, there is more emphasis and expansion of the Chapter 5 'Manhole Rehabilitation'. The release of the 3rd Edition will expansion of MOP-992 into nine chapters and they are as follows: 1.Introduction 2.Safety 3.Inspection 4.Quantification of I/I and Structural Condition 5.Manhole Rehabilitation Methods 6.Examining Cost-Effectiveness of Manhole Rehabilitation 7.Wall Thickness Design for Full-Depth Manhole Rehabilitation 8.Quality Management 9.Summary This presentation will go further to discuss specific technologies under Chapter 5 and will include nearly all of those technologies and products that are currently available for both private and public utilities to consider. These include (a) manhole covers and frames, (b) chimney seals, (c) wall joint seals, (d) injection grouting, and (e) coatings and liners. The presentation will wrap up with a presentation of some asset management strategies (and particularly a condition assessment matrix that is featured in MOP-92) along with the impact that these new approaches will be added to the NASSCO codes for both PACP and MACP.
