Fletcher Construction has recently been applying digital techniques to aid environmental compliance during delivery of civil construction projects. Developments in drone technology and image processing have made producing erosion and sediment control plans more efficiently using reduced survey data. Digital site surveys have been used to produce 3D as-built models of sediment treatment devices to demonstrate compliance with relevant regional guidelines. Accurate and up-to-date imagery has been critical in identifying potential sources of erosion and sediment generation, allowing corrective actions prior to forecast extreme rainfall events.
