The Challenge

Casino Nova Scotia is a 44 million dollar Entertainment Complex constructed on a 3.5 acre lot on Halifax's Waterfront. The casino project encompasses approximately 138,340 square feet of building area and includes a 550 car-parking garage, an exterior Sea Walk wrapping around the Casino and an outdoor Amphitheatre. Approximately 30,000 square feet of this complex is constructed over water, supported by over two miles of concrete filled, steel covered caissons, anchored into the bedrock of the harbour floor.

 

The Solution

Concrete was used extensively on this project as it met esthetic, economic and construction challenges.

  • Concrete is a long-term, durable, low maintenance material and can withstand the sea air better than other building materials.
  • The proven durability of precast concrete makes it an ideal material for parking garages.
  • A multi-layered floor system, with heating conduits, insulation, cables and communication systems can be easily constructed with concrete.
  • Concrete construction meant that local materials and labour could be used, which proved beneficial to the local economy.
  • Concrete block walls were used extensively for their inherent strength, sound insulation and fire separation characteristics.

Construction Methodologies

Precast and Cast-in-Place Innovation

The 30,000 sq. ft. of building area constructed over the water, required innovation in precast and cast-in-place construction technologies. Each floor-supporting caisson consisted of a large diameter steel pipe section that was driven into the bedrock and filled with high strength reinforced concrete. The steel pipe helps to protect the structural concrete from the aggressive seawater for up to 100 years. As each caisson was an expensive endeavour, fewer but larger caissons were used. Ring-shaped pile caps were placed on top of the large caissons to support both the formwork and the final concrete floor structure. As a large portion of the floor is constructed directly over the water in Halifax harbour, an insulated floor system was needed to ensure the comfort of complex patrons. The multi-layered concrete floor system also allowed hundreds of conduits and cables for heat, communication and control/security systems to be cast into the floor.

Exterior cladding of the Casino and the parking structure is a beige toned precast concrete with locally sourced reddish granite aggregate, column base accents and green tinted reflective glazing in pre-finished aluminium framing. The Porte Cochere, Entrance Tower and Pre-Function Tower are clad with precast concrete to match the Casino.
