~ Concrete Girder Bridge on Faison Road
~ 2-span continuous modified bulb-tee girder bridge, with each span 140+ feet long.
~ The deck had been poured except for over the bent, where it had been formed up for the continuous for live load diaphragm and slab.
~ During the main deck pour the long girders deflected more than anticipated.
~ In the area over the bent, the reinforcing steel appeared to have more than the standard 2½" of concrete cover.
~ The deck slab was had a few visible cracks near the end bent.
~ It appeared that the structure will carry a future sidewalk, so there were no dowels cast into the deck slab.
~ Each span had a single line of steel diaphragms.
~ There were questions on the appropriate amount of tension applied to the diaphragm bolts?
~ Steel bridge over US 64
~ Noted various configurations for tall MSE walls:
~~ Wall with reversed wing walls and a single row of piles (on Knightdale Bypass project by Design-Build team).
~~ Wall with turn back, skewed wing walls and battered piles (on Wake Forest Bypass by in-house staff).
~~ Wall that follows the end bent envelope and the cap is supported on a double row of vertical piles.
~ Potential for settlement of embankment should be examined during design of MSE wall.
~ MSE walls with reversed wing walls raises some drainage issues, and
~ Consideration of ease of future inspection.
