realignments by provision of structures and provision of tunnels if required<br />

4. 4.1<br />

a) Inventory and condition survey for tunnels, if required.<br />

b) Identification of faults in rock strata and impact of faults in design of<br />

tunnels, if required<br />

c) Detailed design of road considering and incorporating specific aspects<br />

related to hill region like terrain, topographic conditions, extreme<br />

weather conditions, altitude effects etc.<br />

control/protection works, slope stabilization measures, snow drift<br />

control measures, avalanche protection measures<br />

f) Existing land slide and snow clearance facilities<br />

g) Geological details of rock strata in the area in case of tunnels<br />

7. 4.11(1) The Consultant should make an in depth study of available geological and<br />

meteorological maps of the area.<br />
