1. Project Location is near to the Coastal region, all the structures shall be designed
considering the ‘Very Severe’ Exposer Condition. Hence, preventive measures shall be
considered for the structures for prevention from corrosion in steel, erosion of concrete and
other materials, etc. To prevent corrosion in steel strictly FE500D (Fusion Bonded Epoxy
Coated steel shall be used) confirming to IS: 13620-1993/ IRC 112-2020 specification along
with Galvanized coated binding wire, and minimum grade of concrete M40 shall be adopted
for structures. For Additional details, notes mentioned in GADs shall be referred.

2. To prevent early corrosion in reinforcement, steel bars shall be used with Fusion Bonded Epoxy
Coated confirming to IS : 13620-1993, MoRTH specification 1009.3.2.1 and IRC 112-2020.
Minimum grade of concrete shall be M-40 for all structures.

3. The minimum vertical clearance from cross road in case of all VUP, LVUP, & Flyover structures
shall be as mentioned above.

4. Open to sky median shall be cover by fiberglass roofing sheet along with appropriate frame
structure.

5. The total width excludes the clear gap between two super structures, which will be directed by
the roadway width.

6. RE Walls shall be provided as per Schedule-B.

7. Locations given in the above table are tentative, subjected to site condition. No change of scope
due to change in location shall be given.
8. Chainages may be adjusted according to location of structures as per drawings.

9. In case of grade separated structures like VUP/LVUP, the proposed structure, the finish road
level in VUP/LVUP shall be kept 150mm above the ground level/service road/cross road
(whichever is higher) to ensure that these VUP/LVUP don’t become water accumulation points.
Profile of the cross roads shall be corrected accordingly within proposed RoW.

10. The proposed span arrangement as suggested in table shall be adopted. Any change in proposed
span arrangement, RE Wall length shall be finalized in consultation with AE/NHAI. Any Change
in span arrangement shall not be treated as change of scope, except any variations in the length
arising out of a Change of Scope expressly undertaken in accordance with the provisions of
Article 13

11. Wherever liquefaction is observed in Open / Raft structures, Ground improvement (densification/
ground replacement with suitable soil) shall be done to compact the soil to increase its
penetration resistance and satisfy clause 8.4.4 (v) of IRC 114.8. In the case of Grade Separated
Structures, the type of structure and the level of the Project Highway and the crossroads shall be
