Client: Barn Conversion, Kent

The Brief

Risk Category: Cat 1, 2 head risk, 10 minutes
Number of heads: 40
System Type: Pump and Tank

The project consisted of converting a former storage barn to a single family home. The plans included an open plan entrance with stairs to a first floor balcony leading to the 3 bedrooms and 2 bathrooms.

Under the balcony leads through to the living, kitchen and dining space, off which has a family snug, utility room and home office.

Our design and quotation was made from the plans supplied with the initial enquiry. Initially it required 38 heads and the pump and tank was to be house on the side of the building in a purpose made plant room.

Once the proposal was agreed in principle we attended site to complete a survey and confirm the design. The floor plans provided did not detail the oak beams and rafters that were to remain as a feature. This require some careful planning on our part as we could not drill the original timbers and we had to position the sprinkler heads so that these original features did not obscure the sprinkler heads spray pattern yet still achieve full coverage. The client also had to compromise in certain areas where their preferred design would have had the two sides of the ceiling pitch meet at the apex, there had to be a flat part of ceiling with void above to route the pipework and for the sprinkler head to have the most effective coverage area. The pump and tank location also changed with the addition of a separate garage building with space, power, water and heating to accommodate the equipment. The garage loft location was chosen and a service trench was installed to run the sprinkler pipework from the garage to the house.

At the start of the installation and after the final design and hydraulic calculations were approved the tank was delivered to site. This had to be, once the garage building was formed but the roof was not completed to allow access to site the tank. The pump was installed at the very end of the project as this equipment could fit through the normal access point to the loft. The installation of the pipework and heads took 3 days to complete. The pipework was pressure tested and isolated at the trench location. There was a return visit to install the pipework in the trench, another to install the pump and tank and a final visit to commission.

The system had its own fire panel which is in the house to identify any faults or pump activations as well as an audible alarm for evacuation. An isolation valve is installed in the house but secured in an open position, this can be used for maintenance or to isolate in an emergency.
