Apples to Oranges Procurement of SUE
Are you really getting what you asked for and what happens when you don’t? This session will look at several Procurement Methods, Payment Structures, Qualifications, Scope, Standards and Deliverables. We will as well look at some examples of what happens when you do not follow the applied standards and what it could possibly mean to […]
Two Civil Engineering Student Research Projects
Presentation 1: Longitudinal Bending Performance of Cured-in-Place Pipe Liners Spanning Across Reinforced Concrete Pipe Joints With the increasing use of trenchless technologies, particularly Cured-in-Place Pipe (CIPP) liners, for the rehabilitation of aging wastewater infrastructure, there remains a critical need to evaluate their mechanical performance under various conditions. Existing standards provide insufficient guidance on the longitudinal […]
Practical Considerations of Using ASCE MOP 145 to Facilitate Design and Construction Implementation of Close-Fit Liners
The ASCE Manual of Practice 145 is a robust analytical approach for “close-fit” flexible liner design. Built on the French National Practice ASTEE 3R (2014), is considerably more complex and accurate than design approaches like Appendix X1 of ASTM F1216 for circular host pipe and the WRc SRM Type II design method for non-circular pipe, […]
Report Card on the Development of Pipeline Stress Analysis and Soil-Pipeline Interaction
The study of pipeline-soil interaction started over 100 years ago. Initially it was focused on how soil loads interact with buried utility pipes and culverts. In the 1970s computer based (via dial-up modem) soil-spring models were used to assess the buried pipeline response on the Trans-Alaska oil pipeline. Since then, there have been many significant […]
