Objective: To design and supply the air conditioning systems for the tenants in the mall to their specifications, on time and on budget.

Solution: With 15 different tenant shop layouts including three large multinational stores, and a similar number of specifications, managing information flow with the long delivery periods and short site program was a constant challenge. Working in Zambia extends the supply lines by many weeks and cross border paperwork needs to be prepared far in advance. Combining the responsibility of design engineer and contractor facilitates numerous efficiencies, saving time and money and ensuring the mall was completed on time and on budget.

Objective: To design and supply the air conditioning systems for the tenants in the mall to their specifications, on time and on budget.

Solution: Working 350 kilometres from home adds a number of challenges. With 20 different tenant shop layouts and a similar number of specifications, timeous management of information flow to ensure shops were completed on time despite the long delivery periods was imperative, and was only achieved by diligent planning.

Combining the responsibility of design engineer and contractor facilitates numerous efficiencies saving time and money and ensuring the mall was completed on time and on budget.

Objective: To design and supply the chilled water cooling plant, associated air handling units, air cooled split computer room units and ancillary area systems in the most cost effective way to assist in project cost savings, without impacting on system reliability and functionality.

 Solution: The combination of a professional engineering education and extensive practical experience combined to meet the project requirements. The result was a fit-for-purpose design that met the client’s specifications within the main contractor’s budget restrictions, and a successful handover to a demanding client.

Objective: To provide a new chilled water cooling plant with the highest possible energy efficiency in order to optimise the use of available power on site and maximise the client’s business development.

Solution: By careful overall system design and selection of components in the chiller plant, the highest possible cooling efficiency was achieved and power consumption minimised. The power consumption of the new system is 45% lower than systems previously employed on the site for the same application.

In addition to lower electrical running costs in the form of power consumption and lower maximum demand, the cost savings to the client included lower power supply switchgear and cabling costs associated with the cooling system equipment, as well as a smaller stand by generator installation for the building.

Objective: To provide a new mission-critical computer room cooling plant to serve the first phase and subsequent expansions, split over two floors of the existing office building in downtown Cape Town.

Solution: Initially two of the final three closed-circuit cooling towers were installed, along with the main cooling water reticulation piping, UPS powered variable speed pumping systems and controls, all to serve the computer room cooling units installed in the first phase.

The system was designed to be installed and expanded over two subsequent phases, doubling the initial capacity. By careful design and planning, an additional cooling tower, piping and cooling units were added into the common cooling water system during phases two and three without any interruption in cooling or data center operation, all whilst maintaining N+1 equipment status.
