The project involved the structural design of endwalls to the culvert structure which house 2/2400 RCP and 1/1350 RCP. The pipes were to be jacked into position, under another contract, replacing the existing 3/1800 CSNP structure that was in disrepair.

The configuration of the varied diameter pipes along with their varied sizes makes the endwall a non-standard construction requiring structural design.

RMA’s design included tying the new ends to vertical wingwalls which were modified to suit the site circumstances. Steel schedules for all reinforcing were also provided.
