NOTES

1. THE BRIDGE ALIGNMENT WAS FIXED AS PROPOSED BY THE CONSULTANT WHO CARRIED OUT THE SUB SOIL INVESTIGATION (SSI) OF THE BRIDGE SITES.

2. THE ABUTMENT POSITION AT RIGHT BANK IS FIXED AT BORE HOLE LOCATION. THE DEPTH OF FOUNDATION WAS PROVIDED AS PER THE REPORT OF SSI. THE BORE HOLE WAS NOT CARRIED OUT AT LEFT BANK, HOWEVER SSI REPORT SAYS THAT AS PER EXPOSED BED ROCK, THE FIRM ROCK BASE WILL BE LOCATED AT THE DEPTH OF AROUND 2 TO 3 MTRS BELOW THE EXISTING ROAD SURFACE. THUS THE FOUNDATION DEPTH WAS PROVIDED AS PER THE SSI REPORT.

3. ON ACHIEVING THE FOUNDATION DEPTH AS GIVEN IN THE DRAWING, CONSULT BRIDGE DIVISION ABOUT STRATA ENCOUNTERED AND THEN DISCUSS IF ABUTMENTS CAN BE CONSTRUCTED. ON EXCAVATION, DEPENDING ON SOIL OR ROCK TYPE ENCOUNTERED, INITIAL DESIGN OF ABUTMENTS MAY CHANGE.

4. RC RETAINING WALL, RRM WALL, AND GABION WALLS ARE PROVIDED AS RECOMMENDED BY SSI REPORT. HOWEVER THE QUANTITY MENTIONED IN BoQ WILL VARY AS PER THE ACTUAL REQUIREMENT AT THE SITES. THE QUANTITY OF RC RETAINING MENTIONED IN BoQ IS ONLY FOR ONE WALL OF LENGTH (7 MTRS) AND HEIGHT (6.5 MTRS) BUT ACTUAL REQUIREMENT AT SITE WILL BE MORE AS TENTATIVELY AS SHOWN IN THE DRAWINGS. MOREOVER THE THE HEIGHT OF THE WALL MAY VARY AT UPSTREAM AND DOWN STREAM SITE OF BRIDGE. SIMILARLY THE QUANTITY WORK OUT FOR RRM IS ONLY FOR LENGTH (13 MTRS) AND HEIGHT (5.11 MTRS) AT RIGHT BANK AND LENGTH (6.5 MTRS) AND HEIGHT (5.622 MTRS) AT LEFT BANK. AS RECOMMENDED IN SSI REPORT, THE QUANTITY MAY BE MORE THAN THAT MENTIONED IN THE BoQ. THE QUANTITY OF GABION WALL IS FOR 12 MTRS LENGTH OF 3 MTRS EACH TOWARDS DOWN STREAM AND UPSTREAM INCLUDING 6 MTRS IN FRONT OD ABUTMENT. THIS QUANTITY MAY ALSO CHANGE AS PER THE REQUIREMENT AT THE SITE.

5. FOR STABILITY OF ENTIRE SLOPE AT RIGHT BANK OF THE RIVER, THE RECOMMENDATION OF SSI REPORT WILL HAVE TO BE IMPLEMENTED.

6. AS RECOMMENDED IN SSI REPORT THE RIVER BOTTOM AND SIDES NEEDS TO BE DREDGED AND REMOVE ALL THE MATERIALS UP TO THE DEPTH OF NATURAL BED LEVEL OF REQUIRED LENGTH ON BOTH UPSTREAM AND DOWNSTREAM SIDES OF BRIDGE AXIS LINE TO ALLOW UNHINDERED FLOW IN THE CHANNEL.
