Description of the Project:
The project encompasses 2 bridges that cross high speed waterway, simply supported precast T girders, two wall type piers, and two massive abutments. See figure (109) in the Appendix.
My Role in the Project (in Detail):
1) I was one of the team who inspected the bridges. It was found that there was a scour in front of two abutment’s foundations, and as a result rotations were happened in those two abutments, and was investigated by checking the expansion joints and the in-place probe investigations. Wide cracks were inspected in the abutments as well (after attaching mortar marks on those cracks as a reference). The other deficiencies were: very defective drainage system, lack of protective system and minor substandard clear coverage for reinforcements, see figure (110).
2) I completed the structural analysis by using hand calculations with influence line charts for evaluation and rating purposes, UIC standard train was used as the rating load.
3) I worked in team to provide efficient rehabilitation plan, our team submitted to the client a list of repair works and it contained: crack injection with cement paste, reinforced concrete jackets, in addition to an overall concrete lining for the stream (after excavating, re-directing, and cleaning of the stream bed from debris, plants, logs and large rocks), see figure (111).
4) I drew detailed drawings using AutoCad to clarify the repair work and its sequence.
5) I participate in quantity surveying, specifications preparation, time tables and cost estimates.
