REQUEST FOR PROPOSALS

site to artesian conditions, seismic disturbance and other engineering properties
of soil etc. Geotechnical investigation and Sub-soil Exploration will be done as
per IRC 78-.
5. The scheme for the borings locations and the depth of boring shall be prepared
by the Consultants and submitted to NHIDCL for approval. These may be
finalised in consultation with NHIDCL.
6. The sub-soil exploration and testing should be carried out through the
Geotechnical Consultants empanelled by MORT&H. The soil testing reports
shall be in the format prescribed in relevant IRC Codes.
7. For the approach road pavement, bore holes at each major change in pavement
condition or in deflection readings or at 2 km intervals whichever is less shall be
carried out to a depth of at least 2 m below embankment base or to rock level
and are to be fully logged. Appropriate tests to be carried out on samples
collected from these bore holes to determine the suitability of various materials
for use in widening of embankments or in parts of new pavement structure.
4.11.5. Material Investigations
1. The Consultants shall identify sources (including use of fly-ash/ slag), quarry
sites and borrow areas, undertake field and laboratory testing of the materials
to determine their suitability for various components of the work and establish
quality and quantity of various construction materials and recommend their use
on the basis of techno-economic principles. The Consultants shall prepare mass
haul diagram for haulage purposes giving quarry charts indicating the location
of selected borrow areas, quarries and the respective estimated quantities.
“Environment friendly materials”
“As per MORTH circular No. RW /NH-33044/53/2013-S&R(R) dated
20 th November, 2013, alternative pavement materials and technologies for road
construction shall be assessed and compared in the design stage. The alternative
resulting in substantial reduction in GHG emission and with least life cycle cost
shall be recommended for implementation.
Technical and economic feasibility of using industrial byproducts, recyclable
and waste materials shall be assessed depending on their availability in the
concerned region.
2. It is to be ensured that no material shall be used from the right-of-way except by
way of leveling the ground as required from the construction point of view or
for landscaping and planting of trees etc. or from the cutting of existing ground
for obtaining the required formation levels.
3. Environmental restrictions, if any, and feasibility of availability of these sites to
prospective civil works contractors, should be duly taken into account while
selecting new quarry locations.
4. The Consultants shall make suitable recommendations regarding making good
filling of the borrow and quarry areas after the exploitation of materials for
construction of works.
5. The Material Investigation aspect shall include preparation and testing of
bituminous mixes for various layers and concrete mixes of different design mix
