| F.A.Q's. |
| John Sharratt | M&E Co-ordination Engineer / Design Development. | |
| Royal Bank of Scotland, NCFB, Manchester | ||
With a basement car-park and plant area, nine storeys of office space and a packed roof-top open plant  area,
this has to be one of my most prestigious contracts to date.Plant comprised of eight air handling units, four chillers, four dry air coolers, three packaged generators, two rotary UPS units, a packaged boiler plantroom and a packaged chiller plantroom. Add to this the main switchroom and it becomes apparent just how much kit needed to be serviced. Coupled with all the services support gantries are access platforms and an extensive steelwork structure carrying a window cleaning crane. The rendered section of drawing shown here gives an indication. |

| All drawing work associated with the roof-top
plant area (the size of two football pitches) was produced in 3D. AutoCAD ADT and CAD-Duct Solids were the key programmes used in the preparation of drawings. Multi-services support gantries were used throughout and these, along with 95% of all services including pipework up to 300mm diameter, were fabricated off site under strict quality control to meet a short installation programme. Individual fabrication drawings were produced for all services support gantries and pipework, enabling considerable time savings on site. |

 Photographs
taken during installation indicate the congestion on the roof and
demonstrate the benefits of careful 3D co-ordination and fabrication
off site eliminating the need for welding to be carried out in congested
areas. |
| The main contractor for this prestigious project was Sir Robert McAlpine, with the M&E installation being carried out by N.G Bailey & Co. |
