Every site I have been on in the last 10 years has asked me to quantify stockpile volumes. Whether that be arisings, topsoil, crushed material. On occasions we have had been able to take from stockpiles of crushed and 6f2 that have been generated from demolition of existing buildings on the plot, so i have been asked to quantify and report on our usage.
Some sites have kept their arisings on site, so I have had to survey and report so decisions (by commercial team) on where and how much it will cost to move to other parts of the developments.
