Stiver Engineering provided a custom beam and plate shoring design for the ongoing Northeast Water Purification Plant Expansion Project in Houston. The custom design was greater than 250 feet long. The pit was located next to Lake Houston with a live 74-inch diameter pipe that crossed through the shoring and discharged into Lake Houston. The shoring was installed so dual 108-inch water lines could be constructed. Stiver also prepared a custom pipe support frame that the contractor used to support the existing storm drainpipe while the dual water lines were built.
