ARCHITECTURE

Architectural Design:

This building is a high rise hotel that serves the adjoining casino and spa in Atlantic City. The building has a long floor plan with two large circular ends. This floor plan rises the height of the building. A large Borgata sign, the circular ends and the glazing with fluorescent lights serve as the signature for the building.

The layout was of the floor plans were governed by cost efficiency. Since each of the hotel floors serve the same needs, the rooms and all their amenities, including electricity, plumbing and mechanical needs, were kept as consistent as possible. This allows for ease of construction and cost efficiency.

Major Codes: 1996 BOCA and the 1997 New Jersey Uniform Construction Code

Historical Requirements: No major historical requirments

Major Zoning Restrictions: No major zoning restrictions, no height limitation

Building Envelope:

 The vertical building envelope is made entirely of a glass curtain wall system. Curtain wall is composed of typical 3 ½”light guage mullions and insulated glass panels. The curtain wall is supported by structural tube steel girts.

The roof slab is a 8 ½” structural slab. On the top the slab is a sepertation sheet topped with 3 inches of rigid insulation. On top of the insulation is a board layer topped with concrete.

Structural System

The Borgata Hotel Tower is located on the site of a former landfill. Beneath the landfill is a mix of marine marsh and clay and silt seams. The tower uses a deep foundation system to transfer loads to the earth. The Borgata sits on top of many concrete filled steel tube piles. Cast in place concrete columns support most of the gravity load. High strength concrete shear walls are used to resist lateral loads and some of the gravity load. The tyoical floor system is a 7 to 8 ½” post-tensioned flat slab. This system is used on all of the guest floors and also for the roof. The public floor systems are 12 and 16 two-way structural flat slabs with 10’ x  10’ drop panels where necessary. The curtain wall is supporting by a network of rectangular HSS girts.

Mechanical System

The hotel portion of the project is served by 2 Energy recovery systems (heat wheels). The guest room make-up air and exhaust are delivered through these systems reducing the cooling and heating load on the building. The pool on level 1 in the podium and on level 32 of the tower are each served with a dehumidification system utilizing chilled water as the cooling medium. Each air handler is provided with a Variable Frequency Drive. The remainder of the areas are all served with chilled water coil and hot water coil air handlers. The hotel tower is being provided chilled water and hot water from Marina energy. This is a utility company in Atlantic City that provides these services through a distribution network that has been designed to surround the entire Borgata site. The floor spaces all have individual control being served by a VAV bow with a hot water reheat coil. The VAV box will cut back to 50% prior to the reheat coil control valve opening to allow for heat. There are several exhaust systems within the new building; grease ductwork is used for the room service kitchen. Vapor exhaust for all the dishwashing areas. Miscellaneous exhaust systems are for toilet rooms, etc. The valet drive through is open to the outdoors and has been provided with an exhaust system to remove car fumes and an above ceiling heating system to prevent the floor above from feeling cold.

Electrical System

The hotel tower is powered by (12) 470 volt high voltage feeders from Marina Thermal (Quasi- Utility Co). These feeders supply three substations with (12) 470/480V transformers and distribution boards on levels B, 3 and 39. Each of these substations feed distribution panels (277/480V), transformers (480V/120/208V) and bus duct risers to hotel floors.  Each hotel floor has several 120/208V panels for guest room lighting and power circuits. The podium floors ( B-3) have various panels and dimmers to feed lighting and power circuits. There are multiple power distribution panels (277/480V) for motor loads. There are panels, switches and emergency power feeders in the elevator control rooms for elevators. There are various panels and switches for pool motors and lighting.
