Metropolis Mixed Use Development

Mixed-Use, High-Rise & Hospitality Development Engineering

From the pioneering Metropolis multi-tower complex under construction in Los Angeles, and the Aladdin (a/k/a Planet Hollywood) Resort and Casino in Las Vegas, to the world’s supertall towers such as Lotte World Tower in Seoul, South Korea and Hyundai Udong I’Park in Busan, South Korea, Syska Hennessy Group is a leader in providing highly efficient MEP, fire protection, vertical transportation, information and communication technology (ICT) services, and engineering designs.

Syska has a proven track record in complex mixed-use developments where office, residential, retail, and hospitality components have distinctive design requirements, necessitating phased design and construction schedules over the course of years.

Our approach is to avoid overdesigning systems. We design building systems within one structure that has multiple occupancies and uses. We address each component—office, residential and hospitality—separately; MEP, fire protection and vertical transportation systems operate independently yet congruently within the single building.

Infrastructure is Vital
Syska helps prepare local infrastructure to supply new demands for power, gas, water and ICT prior to construction. Before the $1 billion Metropolis development broke ground for phase 1, we defined upcoming infrastructure requirements to support the entire project for the city and civil engineers. One of the largest single-development projects on the West Coast, Metropolis will introduce 2.1 million sf of new, rentable living space into Downtown Los Angeles.

We deliver sustainable designs to reduce energy consumption, offset operational expenses and meet local code requirements. For Lotte World Tower, which features office, residential, retail and hospitality components, Syska designed a solar panel array and located micro-turbines on the roof to generate on-site power as required by the city of Seoul. Heat reduction for the HVAC system reduces power consumption by four percent by tapping into the city’s adjacent aqueduct system, in effect “borrowing” the ambient cooling of the water source by running it through the system before returning it to the aqueduct.

To achieve water savings of 30 to 40 percent, we designed the system to recycle greywater into potable water for the Century Plaza New Century development in Los Angeles. This multi-billion dollar, phased, mixed-use project will also exceed the local Title 24 energy code requirements for energy savings by 10 to 15 percent upon completion.

Blending New and Historical in Mixed-Use Developments
Existing properties are important revenue generators. So Syska develops scenarios to enable construction to operate alongside existing facilities by reconfiguring electrical and plumbing systems that keep existing buildings fully operational.

For several large, mixed-used projects—such the $2.5 billion New Century Development at Century Plaza or the Waldorf Astoria Beverly Hilton development in Los Angeles—we balance the renovation of a historical property so that it can remain occupied during construction of major new buildings.
