The following procedure is recommended for demarcation of a building.
At some sites of work the contractor brings steel
pieces, erects the same on the ground and start the work of excavation.
In due course these steel pieces are just discarded. Thus no proper
reference point is available while doing further jobs.
Layout of Building
The real meaning and purpose of setting out (layout) is to transfer
the plan, length and width of its foundation on the ground so that the
foundation can be excavated for construction of purposed building as per
The following preliminary works should be executed before actual planning of layout for the house.
For setting out /layout, the most important requirement is to
establish a baseline. This is marked on the ground as per site plan
requirement with the help of offsets which are taken from the existing
road or existing building.
Centre line divides the plan into two equal parts. This can be marked
in the field with the help of baseline. This line is very necessary and
useful for layout. This line should be transferred to Burjis and be
kept up to the completion of foundation work.
Burji or marking pillars are masonry pillars constructed with bricks
and cement mortar. These are constructed on both ends of walls /columns
and center line should be marked on the top surface of the burjis with
the help of base line. Burji is also constructed for indicating the
plinth level of the building. Burjis are very useful for the layout.
Accuracy of the foundation can be checked with the help of Burji at any
time during construction. Burjis should be kept intact till completion
of foundation work.
