Park have resulted in a scheme which does not rely on the building of a retention dam on the precinct and the stormwater run off has been dealt with by draining the hard roof run – off down the exterior building columns either onto the landscaped courtyards or the street levels , where it is systematically drained down through the supporting columnar structure to the subsurface drainage run-off trenches .
Similarly the balance of the Wet Services have been drained down to basement subsurface trenches and led away to the sewer outfalls along the eastern boundary .
Electrical Services Fortunately , the existing development had been provided with sufficient electrical power loading to accommodate the full quota for the entire envisaged development and the Eskom disaster had no effect on electrical provision to the new precinct .
Two separate high voltage chambers supply low voltage Transformer Rooms located adjacent to two standby generators to supply all the requirements of the mixed use buildings . Standby power supplies emergency services and lighting . higher co-efficiency of the building services performance in terms of both energy and cost efficiency .
Construction A two and a half year project from bulk excavation to handover , this phase of Melrose Arch has tested and challenged the creativity of both the consultant team and construction team in a joint effort to achieve a unique set of individualised buildings all built on time .
Whilst not relying on a Project Manager , the consultant and contracting team have managed with the client , Time Managers , the Contractors Programming team , and Tenant Co-ordinators for both the Retail and Office sections to turn out a uniquely different and compact scheme with tight budget restraints .

Air-Conditioning Services Careful detail interventions with the architects in the initial stages of design have resulted in reductions to heat loading , with performance glazing , roof insulation and detailing to the façades that included deep set window penetrations , sun screening and shading overhangs .
Thereafter , the scheme has been designed using chilled water fan coil units all supplied by the District Cooling Units which are systematically extended to accommodate the loading as the precinct grows .
Digital Technology Incorporating the existing centralised systems remained a prerequisite of the clients ’ brief . The new development has been merely added on in modular units to the fully integrated building services scheme ; a single control room , the Precinct Integrated Engineering ( PIE ) Centre controls both the existing and new precincts ’ building management systems , ensuring supply of all standard services , the metering thereof and security ( access control , surveillance ) by means of a digital backbone .
The continued development and use of the centralised systems ensures efficiency and long term sustainability and is felt in the reduction in operational costs which is a result of the economies of scale created by the increased size of the precinct , greater diversities , and
