Meissner’s Project Management team were responsible for the smooth coordination of the project. Rantsho went on to state, “We were very pleased with the meticulous planning, time and effort that went into the project from all parties concerned. This was critical as the installation was done alongside a major upgrade of the Sechaba Administration system and the platform that it runs on".
In order for the installation to be carried out Meissner had to arrange for JHB’s City Power to switch off the transformer supplying the entire city block for 2 days. The new generator weighing 11 tons is installed in the basement of Sechaba’s office block and access was gained by using a crane to lift the generator over the top of the 5 storey building, move it 50 metres inwards and lower it down 7 storeys through the centre of the building into the basement. For the project Meissner hired a 49 metre high, 440-ton crane that took a day to assemble on site. The team also had to arrange for the block in central Johannesburg to be closed off to traffic for an entire weekend. In addition to this new cabling had to be installed. Donovan Ramage, Meissner’s Project Manager commented, “The cabling was a massive undertaking as we had to deal with a number of restrictions including access and space constraints as well as safety issues.”
The Himoinsa Generator was supplied in a weatherproof, sound attenuated enclosure making the unit incredibly quiet. The generator’s exhaust system is reticulated from within the basement to a suitable well-ventilated point where fumes that have been filtered and catalyzed are safely expelled from the building. The unit has an auto changeover mechanism as well as a 2 200-litre bulk storage diesel tank ensuring that should Sechaba lose electrical supply that they can run at full capacity for up to 3 days. The generator is linked to Sechaba’s Building Management System (BMS) allowing them to continually monitor the status of the generator. The generator has been configured to a specific set of parameters and automatically starts up 30 seconds after power to the building has been lost and will continue running for at least 5 minutes after power has been restored.
