COMMERCIAL BUILDING - GALLIPOLI (LE), S.S. 274 - Fire safety Design

The fire prevention project on the adjustment to the fire regulations of a commercial property, as a result of internal restructuring and change of the type of business, resulting in the existing hazardous substances into the room.

The property will become a selling point of a major national retail chain.

The works, as mentioned, consist of works of Internal restructuring.

The building is composed of only the ground floor used as a general supermarket and containing goods of a local special reserves. E 'it isolated on all four sides.

The building is located on the S.S. 274, and occupies a floor area of 1,000 square meters.

The building is intended to general supermarket, it is realized with load bearing structures a.c. and for tamping of the masonry of 30 cm thickness, and will be composed by the set of individual functional units listed below:

• sales area 
• goods reserves
• refrigerator compressor plant with central TN and BT in a special technical room

The assessment of the fire load was made in function of the type of goods hypothesized present in the most severe situation and all of those fuels furnishings.

Were then identified areas of all commodities similar, has computed the theoretical volume from these busy (shelving surface x height Stacking theoretical = 1.80), the various waves produced get a real amount of commodity expressed in volume. At this point, each product was assigned the gross calorific value of power and has made the value of the fire load available for it.
