NZGS have identified an area for which we would like to develop a short Practice Note to assist the geotechnical profession in NZ.  The design and use of subsoil drains in earthworks projects varies around the country with different practitioners, different regulatory environments and varying geological settings.  We would like to develop a Practice Note to set out good practice in the design and use of subsoil and construction drains, including some discussion on inspections and maintenance requirements (as necessary), and the use of filter mediums; for predominantly residential earthworks projects.

If you have experience in the design and installation of subsoil drains, and have a passion for sharing your knowledge with a view to consistency and clarity of purpose, then please put your name forward.  We aim to put together a small working group to build a Practice Note over the next 12 to 18 months.  The work will be on a voluntary basis with an anticipated commitment of 2 to 3 hours a month.
