The Farringdon East OSD Project consists of 5 CAT A floors, mezzanine plant area, roof and reception. The project is now complete
The IDSL scope of works is to install all of the GSS ductwork and fire rated ductwork along with the free issue fan coil units, plenum boxes and grilles on the Farringdon East OSD. Fire Protection had been appointed by IDSL to supply the fire rated ductwork and install the insulation to the fire rated ductwork once the installation was complete.
There are 4 main air handling units serving the office floors are situated on the roof, two dedicated air handling units also serve the mezzanine floor and ground floor, this is comprised of a plant area and staff changing rooms, cycle store, refuse store, reception and showers. A dedicated fan serves the toilets that are on situated on the CAT A floors. Each CAT A floor has fan coil units installed, which are supplied fresh air from the roof AHU’s. The extract air is drawn out of the ceiling void via the extract ductwork system. IDSL have installed fire dampers and motorised fire/smoke dampers as detailed to provide compliancy to the building fire strategy.
Two DX systems have been installed by IDSL within the comms room on the mezzanine and within the dock office in the loading bay.
A dedicated extract system serves the loading bay that is situated at the rear of the building.
Whilst installing the ductwork on the roof IDSL had to take care not to install services that were above the line of the roof screens.
