                     Generally

               D.1   Soil description

                               the post contract water level. Where ground water levels are subject to periodic
                               changes due to tidal or similar effects they shall be so described and the average of
                               the mean high and low levels given.
                          b.   Trial pits or bore holes stating their location.
                          c.   Over or underground services.

                     2.   If the above information is not available a descfiption of the ground and strata which is to

                     shall be enumerated and classified in stages of 300mm girth (measured at height of 1.00m
                     above ground). Filling in voids, if required, afier removal of tree roots shall be given in the
                     description.
