Precise Culvert Length and Location with Drainage Strings

We started off this year’s 12d Training Webinar Series with a replay of an extremely popular topic from May – ‘Precise Culvert Length and Location with Drainage Strings’. This topic was presented by Owen Thornton of 12d Queensland.

This session demonstrates how to align and grade a Drainage string culvert with precision, in both the horizontal and vertical, to best suit the batter slope of the road it crosses and to allow for an integer number of pre-fabricated pipe/box lengths.

Plan and long-section plots of the culvert are produced. The culvert and its headwalls are also converted to trimeshes, for use beyond hydraulic modelling, e.g. road design and BIM.
