BEAM CAMBER AND BUILD-UP NOTES:
Bottom of Deck
The build-up values given in the 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.
| Span
If the predicted cambers based
on field measurements differ more than +/- " from the theoretical "Net Beam
Camber @ 120 Days" shown in the Data Table, obtain approval from the Engineer
Top of Beam
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
Begin Span
of 21 days prior to casting.
End Span
DIM "A" includes the weight of the Stay-In-Place Formwork.
