The North American Society for Trenchless Technology (NASTT) will offer a virtual training course titled HDD: Calculations & Advanced Design Good Practices Thursday, April 24, from 11 a.m. to 4 p.m. Eastern Time.
This five-hour course is based on advanced modules from the recently released 5th Edition of NASTT’s HDD Good Practices Guidelines and is designed for industry professionals with a foundational understanding of horizontal directional drilling.
The session will focus on critical advanced design considerations, including a detailed examination of geotechnical conditions and associated risks, as well as important aspects of contract documents. Participants will also gain an in-depth understanding of essential calculations for assessing and mitigating risks in HDD crossing designs. Topics covered include:
- Hydrofracture risk analysis;
- Pullback and pipe stress calculations for various pipe materials; and
- Settlement risk evaluations.
These calculations are frequently required for securing permits from various stakeholders such as departments of transportation, railroad owners, environmental agencies and flood control agencies.
The course fee of $250 for members and $300 for non-members includes attendance, course handouts and a Continuing Education Unit certificate issued by Louisiana Tech University. The digital training manual will be provided prior to the course. Please note that this five-hour course does not include a copy of the HDD Good Practices Guidelines, 5th Edition.
The course will be instructed by NASTT members and professional engineers Mary Neher, Matthew Wallin and Diana Worthen. Click here to register.
