BEAM CAMBER AND BUILD-UP NOTES:
The build-up values given in the Data Table* are based on theoretical beam cambers.
The Contractor shall monitor beam cambers for the purpose of predicting
camber values at the time of the deck pour.

If the predicted cambers based

from the theoretical "Net Beam
Camber @ 120 Days" shown in the Data Table*, obtain approval from the Engineer
to modify the build-up dimensions as required.

When the measured beam cambers
create a conflict with the bottom mat of deck steel, notify the Engineer a minimum
