The Esplanade project involved construction of a riprap causeway, drilling & blasting of the seafloor and employing a team of divers to assemble steel flanges on lengths on 18” HDPE pipe, installation of a precast concrete structure underwater, backfilling the underwater trench with ballast stone and boulders, and removal of the causeway. C. Brito Construction Co., Inc. designed and fabricated two custom lifting mechanisms and developed specialized equipment to meet the ever-evolving challenges presented by 6 redesigns over the course of the project.
