26IS THERE A SOLUTION ??
Yes
With the Existing Bridge File in Hand
VISIT EVERY BRIDGE SITE DETERMINE IF THE FILE
REPRESENTS THE BRIDGE -- THE BRIDGE HAS BEE
N RATED FOR LOAD CAPACITY BY LF --
IF YES -- COMPLETE ROUTINE INSPECTION AND GO T
O THE NEXT BRIDGE
27SOLUTION (Continued)
ALSO, IF THE FILE DOES REPRESENT THE
BRIDGE DETERMINE IF THE BRIDGE HAS BEEN RATED
BY LF. IF NOT, DETAIL AS NEEDED FOR RATING BY
LF. COMPLETE THE ROUTINE INSPECTION AND GO T
O THE NEXT BRIDGE.
28SOLUTION (Continued)
IF THE FILE DOES NOT REPRESENT THE BRIDGE
COMPLETELY RE-INSPECT AND DETAIL THE BRIDGE.
COMPLETE THE ROUTINE INSPECTION AND GO TO THE
NEXT BRIDGE. RATE THE BRIDGE FOR LOAD - CARRY
ING CAPACITY BY LF.
