l) Calculations as appropriate to support work proposal
The Contractor will prepare and submit to the Engineer, detailed drawings
of the excavation and filling work necessary, as proposed to be executed
by him, showing the dimensions as per drawings and specification, adding
his proposals for slopes, approaches, dewatering sumps, berms etc. On
receiving the approval from the Engineer with modifications and corrections if
necessary, the Contractor will set out the work from the control points
furnished by the Engineer and fix permanent points and markers for future
checking. These permanent points and markers will be checked by the
Engineer and certified by him after which the Contractor will proceed with
the work. Engineer shall be provided with necessary men, material and
instruments for such checking. It should be noted that this checking by
the Engineer prior to start of the work will in no way absolve the Contractor of
his responsibility of carrying out the work to true lines, levels and grades as
per drawing and subsequent corrections, if any. In case any errors are
noticed in the Contractor's work at any stage, the same shall be remedied by
the Contractor.
Initial levels either in a definite grid pattern or as directed by the Engineer
will be taken by the Contractor jointly with the Engineer over the original
ground prior to starting actual excavation work and after setting out.
These initial levels will be used for preparing cross-sections for volume
measurement or for cross-checking the depths obtained from tape
measurements. These initial levels and cross-sections shall be jointly
signed by the Contractor and the Engineer before commencement of work.
