structures requiring widening (for such structures indicate widening
methodology);
structures that shall be retained.
3.3.6 Soil, geotechnical, material, hydrology and drainage surveys
The activities and deliverables forming part of the soil, geotechnical, material,
hydrology and drainage surveys are described below:
(a)
The characteristics of the existing soil, two samples from every five km of
the Project Highway or closer where change in soil type is encountered.
(b) The determination of subgrade CBR (soaked) every three km of the Project
Highway or closer where change in soil type is encountered.
(c ) Benkleman Beam Deflection measurements on the Project Highway – one set
of ten readings in 250 m for every three km of the Project Highway.
(d) Investigations of the subsoil strata (one trial bore and/or test pit at embankment
and one in river bed at locations where new bridges or other structures are
proposed. The depth of trial bore/ test pit shall be as per IRC standards).
(e) Preliminary hydraulic data for bridges, design discharge, HFL, LWL, etc. with
a view to checking adequacy of existing waterway.
(f) A broad assessment of the drainage condition and requirement of the Project
Highway.
3.4 Proposal for Sections passing through urban areas
(a)
(b)
The task at 3.3.2(c) would identify the stretches of the Project Highway
which pass through the urban areas. For each of these stretches, the
Consultant shall prepare an improvement plan of the stretch to provide a
four-lane divided carriageway with footpaths, covered drains, etc.
Possibility of providing service roads shall also be explored and indicated.
If there is any constraint due to available ROW or additional land to be
acquired, the same shall be brought to the attention of the Authority on
immediate basis. In such situations, a bypass may be needed to avoid the
urban area. The surveys and investigations for the alignment and other
features of the bypass are also a part of this Consultancy.
Bypasses:- Construction of bypasses should be identified on the basis of
data derived from reconnaissance and traffic studies. The available
alignment options should worked out on the basis of available maps. The
