4.12 Detailed Design of Road and Pavements, Bridges, Structures
4.12.1. General
1. The Consultants are to carry out ‘good for tender’ designs and drawings for the
following:
4.12.2. Design Standards
i. high speed highway with divided carriageway configuration complete in all
respects with service roads at appropriate locations;
ii. design of pavement for the additional lanes and overlay for the existing road,
paved shoulders, medians, verges;
iii. bridges, viaduct/subways and other grade separated structures including
ROBs/RUBs etc.;
iv. at-grade and grade-separated intersections, interchanges (if required);
v. ROB for railway crossings as per the requirement and the standards of the
Indian Railways; and,
vi. prepare alignment plans, longitudinal sections and cross-sections @
50mintervals;
vii. designs for road furniture and road safety/traffic control features;
viii. designs and drawings for service road/under passes/overpass / cattle passes tree
planting/fencing at locations where necessary / required;
ix.. toll plazas and office-cum-residential complex for PIU (one for each civil
contract package);
x short bypasses at congested locations;
xi. drainage design showing location of turnouts, out falling structures, separate
drawings sheet for each 5 km. stretch.
xii. bridges and structures rehabilitation plan with design and drawings;
xiii. traffic amenities (Parking Areas, Weighing Station and Rest Areas, etc.);
xiv Design of pavement for approach road
xv Design of river bank protection / training works -Innovative type of
structures with minimum joints, aesthetically, pleasing and appropriate
to the topography of the region shall be designed wherever feasible.
1. The Consultants shall evolve Design Standards and material specifications for
the Study primarily based on IRC publications, MORTH Circulars and relevant
recommendations of the international standards for approval by NHIDCL.
2. The Design Standards evolved for the project shall cover all aspects of detailed
design including the design of geometric elements, pavement design, bridges
and structures, traffic safety and materials.
4.12.3. Geometric Design
1. The design of geometric elements shall, therefore, take into account the essential
requirements of such facilities.
2. Based on the data collected from reconnaissance and topographic surveys, the
sections with geometric deficiencies, if any, should be identified and suitable
