Upgrading an existing Data Centre Part 3

Well its been a hard shift. Data Room 7 is nearly finished and ready for handover. It has been one of these projects where the hard bits have been easy and the easy bits have proven to be hard.The upgrade of the main incoming electrical supply which on the face of it was fraught with disaster actually went very well and gave us no issues at all, other than the fact that the day we planned it coincided with the heavy snow falls just prior to Xmas.The easy bit, which should have been converting an office to a Data Room fell apart a bit because the building firm went burst in the middle of the project.But the rasps this time went to GEA Denco who managed to allow 6 air-side dry coolers to freeze up and shatter their coils over the Xmas period....What Glycol, I hear you say. EXACTLYAh well, onwards and upwards and at last GEA Denco are coming to the end of their commissioning process.Next week sees final clean up and Fire Suppression connections and its given to the sales guys to sell.Nothing can go wrong now....Can it?????
