Select and stack the required material in such a place that it should not obstruct other construction activities. All the sides of the building must be sealed for the safety propose.Įstimate the excavated stuff to be re-utilized in filling, gardening, preparing roads, etc.As far as possible try to carry excavation and filling simultaneously to avoid double handling.Construction of dewatering wells and interconnecting trenches are to provided if needed.If the site is located in loose soil area, proper shoring must be done to hold the loose soil.Dressing of excavated pits is to be done as specified in the drawings.Minimum of 1m distance must be maintained between the stocking of excess soil and pit, so that due to rain or other forces the soil should not sweep into the pits.

The major works done before, while and after excavation are as follows, Excavation line is marked in dotted line. These grid lines are so aligned that the line falls on the excavation and footing.Įxcavation drawing represents the length, width and depth of the excavation. Gridline drawings represents the grids marked in numbers and alphabets whose measurements are shown for site marking out reference. Centerline Drawing or Gridline Drawingĭrawings Required for Excavation 1.
