NU girder depths documented in the guideline vary by different increments with a 300 mm difference between the 900 and 1200 girders and 400 mm difference between the 2000 and 2400 ones. Girder depths have been produced in the past that are different than the 7 sizes in the guidelines. Has the Ministry considered the addition of more standard sizes (using say 100 mm or 200 mm increments) or even the addition of 1000 and/or 2200 girders to eliminate the large difference at the lower and upper depths?
Figures 9 and 10 appear to be very similar. Will these be combined into one figure?
The proposed details for the side-by-side girders/slabs (SS107-15, July 2023 and SS107-26, Aug 2023) are showing just one single detail of steel ties between box girders / solid slabs. This single detail is showing a tie plate between two girders/slabs that are shown to be level/horizontal (not slanted following deck cross fall is in current details). Does this single detail with the girders/slabs being shown as level, means that the Ministry will require new designs using side-by-side girders/slabs to show them level/horizontal on the bearings at supports?
