Join us for an educational luncheon on Technical Specifications for Gravity CIPP Rehabilitation: Should You Stick with ASTM F1216 or Move to ASCE MOP 145?
For decades, the trenchless rehabilitation industry has relied on ASTM F1216 as the primary design and specification reference for Cured-in-Place Pipe (CIPP) rehabilitation of gravity sewers in North America. However, after a newer structural design framework (i.e., ASCE MOP 145) was introduced in 2021, questions are emerging about whether the traditional F1216 approach remains sufficient for modern rehabilitation challenges. This presentation examines the practical implications of specifying CIPP designs using F1216 versus the newly introduced MOP 145. While ASTM F1216 provides a straightforward and familiar design method, it was originally developed for relatively ideal conditions and does not fully address challenges such as non-circular pipes, large deformations, significant defects, or significant variability in liner material properties. ASCE MOP 145 introduces a Load and Resistance Factor Design (LRFD) methodology that accounts for uncertainties in loads, material performance, and installation conditions. This approach allows more accurate and defensible liner designs while improving alignment between engineering expectations and contractor means and methods. This presentation provides practical guidance for Utility Owners, Engineers, and Contractors on when ASTM F1216 remains appropriate and when the enhanced framework of ASCE MOP 145 may offer better reliability. The session will walk through the procedural steps of both F1216 and MOP 145. Case studies and design comparisons will illustrate how both approaches can be applied to support informed specification and long-term performance of gravity sewer rehabilitation projects.

The NASTT Mid-Atlantic Chapter invites industry professionals to join an evening of networking, learning, and connection with fellow members of the trenchless technology community. This event will feature a technical presentation by Jason Newman of JF Creamer & Sons, on Trenchless Rehabilitation Solutions for Water Pipelines and Rising Force Mains.
Attendees will have the opportunity to connect with peers from across the region while enjoying a relaxed, happy hour environment. The evening will include a buffet-style dinner, a cash bar for beer and wine, and plenty of time to engage with colleagues, exchange ideas, and build professional relationships. Whether you are looking to expand your knowledge, reconnect with industry partners, or meet new professionals in the trenchless community, this event provides a welcoming setting to do so.
Sponsorships available during the registration process!
Join us for a FREE half-day seminar on trenchless technology featuring industry insights, case studies, and practical applications from municipal leaders and trenchless professionals. Hear directly from City of Oklahoma City and City of Norman as they share real-world project experiences, lessons learned, and strategies for successful underground infrastructure rehabilitation and replacement.
This educational event is ideal for municipal staff, engineers, contractors, consultants, and anyone involved in underground utility management. Attendees will gain valuable knowledge on current trenchless methods, project planning considerations, cost efficiencies, and innovative solutions that minimize surface disruption.
Join us for an educational luncheon on the Capital Line Storm Storage Tunnel project is part of the early works scope for the Capital Line South LRT Extension.
The Capital Line Storm Storage Tunnel project is part of the early works scope for the Capital Line South LRT Extension. The project includes a construction of a 1000m3 capacity storm storage tunnel for groundwater and surface drainage, along with a lift station and forcemain that discharges stormwater to the existing trunk along 23 Avenue. Design of the tunnel required the future LRT underpass to drain into a gravity tunnel beneath and drop into a storage tunnel to be pumped out at low flow periods. This presentation will go through the process of the design decisions which pushed the tunnel and lift station to depths exceeding 20m, also the tunnels storage volume and various connections needed. Construction challenges will be reviewed as well as lessons learned from the work.
Presenter: Chris Lamont, C.E.T, P.Eng
Chris is a civil engineer with 15 years of experience in engineering, construction inspection and surveying. Chris conducts feasibility assessments and designs of trenchless methods which include tunnelling, microtunnelling, horizontal directional drilling, auger boring, pipe ramming, sliplining, and Direct Pipe municipal as well as infrastructure using conventional installation. He provides support across the company on civil infrastructure projects focusing on the application of various trenchless methods.
Presenter: Sam Saunders, P.Eng
Sam is a civil engineer specializing in trenchless technologies for linear infrastructure projects. Sam is responsible for the assessment, design, and implementation of both trenchless new installations and rehabilitation works. He has experience with a variety of methods including microtunnelling, horizontal directional drilling, cased crossing installation methods, hand tunnelling, sliplining, cured-in-place pipe lining, and spray-applied pipe lining.

Presenter: Erez Allouche, Ph.D., P.Eng
Dr. Erez Allouche has devoted much of the past three decades to research and practice in the field of underground infrastructure. His work focuses on the development of new condition assessment technologies and the design and analysis models for underground construction using trenchless methods. He specializes in the design of complex Horizontal Directional Drilling (HDD) and microtunneling crossings, and to date, has completed the design and/or construction oversight of more than 160 such crossings around the world. These installations have included crossing of major highways, railways and rivers. His design experience also covers crossings utilizing other trenchless methods such as Direct Pipe™, pipe jacking, auger boring, pipe ramming, down-the-hole hammer and horizontal direct bores. Prior to joining Stantec, Erez was a Professor of Civil Engineering at Louisiana Tech University and the Director of the Trenchless Technology Center. He is the inventor/co-inventor of 17 patents in the area of trenchless technologies, and the author/co-author of more than 260 publications in the areas of buried infrastructure management and pipeline installation using trenchless techniques.
