sidhi-singrauli (nh-75e) - Madhya Pradesh Road Development ...

Request for proposal for preparation of feasibility report for four laining with paved shoulder of Sidhi to Singrauli (NH-75E)
Topographic Survey
Attachment A to the TOR
1. The field surveys would be sufficiently detailed to meet the following objectives:
(i) Finalising the alignment including location of new bridges and other grade
separated structures.
(ii) Preliminary layout of intersections and grade separators.
(iii) Preparation of Land Plans for acquisition of additional land where
necessary.
(iv) Plans for shifting and relocation of utilities.
2. The field surveys shall be carried out using high precision instruments, i.e. total
stations and would cover the following activities:
(i) Running a continuous open traverse along the existing road and
realignments, wherever required to improve geometrics.
(ii) Collection of details for all features such as structures (bridges, culverts,
etc.) utilities, existing roads, electric and telephone installations (both O/H
as well as underground), huts, buildings, fencing, trees, oil and gas lines,
etc. falling within the extent of survey.
3. The width of survey corridor shall be as under:
(i) The topographic surveys shall cover sufficient width beyond the centre line
of the carriageway considering height of the embankment. The width of the
survey corridor shall take into account the existing land width,
realignments, service roads, if any, layout of intersections, extent of
embankment and cut slopes and the general ground profile.
(ii) In case need for bypassing the congested locations is felt and the feasibility
study for the bypass is included in the TOR, preliminary survey would be
carried out along the possible alignments in order to identify and select the
most suitable alignment for the bypass. The final alignment shall be got
approved by the Authority. Further surveys shall be carried out along the
final alignment.
(iii) Where existing roads cross the alignment, the survey shall extend to a
minimum of 100 m on either side of the road centre line and shall be for
sufficient width to allow improvements, including at grade intersection.
4. The important features of the survey conducted and the reference points taken in
consideration like GPS bench mark, temporary and permanent bench marks, etc.
shall be listed in appropriate formats.
