Gold Reef City Casino Refurbishment – Johannesburg, South Africa

Gold Reef City has a state-of-the art casino with the latest gaming technology, a hotel, and live entertainment venues, plus a recreated gold rush town in the adjacent theme park and the Apartheid Museum right next door.



The refurbishment of the casino marks a relaunch of the Theme park and the Casino. Renewal of the facilities aims to elevate it to a distinct, first-rate recreation destination.


Gold Reef City is a fully operational casino and the HVAC system had to remain operational through the construction/refurbishment process. 

Our Approach / Services

WSP was commissioned as the Mechanical Engineers for the refurbishment of the HVAC installation.
Extensive on-site investigations had to be done to co-ordinate services through existing areas. Due to the extremely tight program, on site attendance, problem solving and extensive co-ordination on drawings and on site formed part of our responsibilities.

Services were rolled out in three phases:
Phase 1
13-off Air-cooled heat pump package units positioned on the Roof provide air-conditioning to the Cinemas, Ten Pin Bowling and Spur extensions. 2-off the existing chilled water air-handling units were refurbished and repositioned to serve the refurbished food court and fast food outlets. Existing chilled water air-handling units were refurbished to serve the new Magic Company, Ten Pin Bowling and Pavilion Office areas within the existing Casino footprint.

Phase 2
3-off existing chilled water air handling units were refurbished and one new chilled water air-handling unit was added to serve the four new restaurants within the casino footprint.
A new heat pump chiller was installed to serve the new Smoking Privé and office extension. The new extension portion, as well as the existing Tables area is served by underfloor air-conditioning system. New extract systems were installed to extract the smoking areas as per SANS 10400.
The new offices above the Privé extension is served by chilled water fan coil units.

Phase 3
Phase 3 encompasses the mechanical, electrical and automated control system refurbishment of the existing air-conditioning and air distribution systems.
The new central building management system was introduced which integrates and allows central plant control of the new and existing development air-conditioning and central cooling plant. Outcomes
The HVAC refurbishment and extensions to Gold Reef City Casino comprises of six new cinemas, new Smoking Privé, five new restaurants, three new fast food outlets, new Magic Company, new Ten Pin Bowling and two refurbished existing restaurants and new offices.
The new central building management system allows fault and energy management of the Casino’s A/C plant as well as key services.
