The North American Society for Trenchless Technology will hold two virtual courses in November: HDD Calculations & Advanced Design Good Practices Course Nov. 7 and the CIPP Good Practices Course Nov. 13-14.
The HDD course is NASTT's newest offering and will be held from 11 a.m. to 3 p.m. ET. It is geared toward industry professionals who have an understanding of the basics of HDD construction. This session focuses on advanced design considerations that are specific to HDD projects.
The presentation includes a detailed look at geotechnical conditions and potential risks related to ground conditions, as well as a discussion of contract document considerations. The course also includes an in-depth discussion of the various calculations that are needed to assess and mitigate risks when designing HDD crossing geometries, including hydrofracture risk analysis, pull back and pipe stress calculations for various pipe materials, and settlement risk evaluations. These calculations are often required to secure permits from departments of transportation, railroad owners, environmental agencies and flood control agencies, among other stakeholders.

The all-new NASTT CIPP Good Practices Course has been updated for 2024 and will be held from 11 a.m. to 3 p.m. both days. The course provides a comprehensive overview of gravity sewer CIPP rehabilitation from planning, through design, project implementation and verification. It also provides an overview of CIPP in pressure applications and in sewer lateral programs.
Major updates in design include both the most current ASTM F1216- Appendix X1 releases, ASCE MOP 145 and an overview of the soon to be released American Water Works Association Design Appendices for Pressure Pipe Design of CIPP. Other enhancements include environmental and safety aspects of CIPP, and the latest research on VOC management.
