Figure 3.9 Author’s design of aesthetic, strong, and easy-to-repair concrete parapet.
Wide cracks at piers need to be pressure grouted with epoxy grout, as recommended in the
inspection report. Design of required repairs and retrofits to substructure will consider:
• Modern countermeasures technology requires new construction techniques. The contractor
performing such tasks will need properly trained construction crews.
• Providing cofferdams, sheet piling, and bed armoring will require temporary construction
work. Alternatives for using quick construction should be considered.
