august 2019 csengineermag.com 31 power issues due to temporary labor shortages. We were fortunate to have found a shipyard that we trusted and worked closely with during the build; our engineers, project managers and operational team visited during the process. Secondly, extreme, inclement weather impacted the build as materials were waylaid in various locations due to weather and the transport of the attenuators was elongated. Ultimately, once the attenuators arrived, the installation went smoothly and we have seen the performance enhancement that we had hoped to achieve. Sustainable, Environmentally Friendly and ADA Compliant: • The team used a variety of materials to build the marina which considered environmental, maintenance and durability concerns – as ONE°15 Brooklyn Marina is subject to challenging New York City weather and harbor conditions. • The marina's internal docks for small- to medium-sized vessels were made from light-weight frame aluminum docks with a lattice decking to permit light to transmit to the water below. While larger concrete docks were used elsewhere in the marina, where possible, these environmentally sustainable docks and decking were deployed. • Additionally, a majority of the marina was moored using an elastic mooring system instead of the traditional metal chain system. By doing so, the team was able to deploy concrete blocks to anchor the docks that have a lower footprint on the seabed. • Due to the natural conditions in the harbor, as well as increased traffic from ferries and high-speed boats, the team determined that to create the calmest marina in the New York Harbor and protect and provide its customers with the best water experience, the use of piles in certain locations – most notably for its wave attenuator and large craft berthing areas – would be advantageous. • The team worked with city officials and the Brooklyn Bridge Park on a set of large steel wave attenuators which were ballasted down on piles to protect the marina. A smaller set of concrete attenuators, anchored on the elastic mooring system, was deployed along Pier 5 to protect the marina from waves beneath the open pier. • Integration (and protection) of anchoring and dock materials remained a priority for ONE15. While larger boats and areas needing more protection had concrete docks and piling deployed, smaller boats and less exposed areas utilize lighter weight materials. Finally, the community dock has sturdier concrete docks for stability and ease of access for larger groups. • The team also installed a solar-powered lighting system within its docks to provide additional safety and considered ADA needs to create the only handicap-accessible marina on the New York Harbor.
