~ The Geotechnical Unit noted that steeper slopes between the end bents for structures #2 and #3and the MSE walls would have reduced the surface area of MSE wall. ~ It was suggested that driving piles for future widening was preferred over the hollow pipe blockout typically used. ~ Underside of top flange of bulb-tee girders spalled when drilling holes for overhang falsework hangers. It was suggested that forming the holes with PVC pipe may be preferable. A/I ~ Structure Design will bring up the holes for overhang falsework hangers issue for discussion at the next PCI-DOT Joint Committee meeting.
~ 12 bridges, 5 culverts and 4 walls ~ Girders at Structure #11 and Structure #12 were not properly seated on the bearings once the diaphragms were installed. ~ Structure #10 has a 0.07 superelevation bridge deck on metal sip forms. Structures #2 and #3 are curved steel girders.
