Nursery school extension - Gradara (PU)

Our company has been officially awarded the work of planning and construction of the extension of the town nursery school on via Tavullia in the town of Gradara in the province of Pesaro Urbino.

The extension of the school building will be carried out with a wooden support structure with a total surface area of about 230 m2, which is highly fire-resistant, is anti-seismic and, with low energy consumption, the construction will have an energy class "A".

The new school complex will be built according to the current anti-seismic, fire prevention and plant design legislation, taking particular account of the overcoming of architectural barriers to make it accessible to the handicapped and the use of renewable energy sources. This new school complex will thus represent an example of the mode of construction of the new millennium, focussed on energy consumption and reduced maintenance.

The choice of wood

Wood was one of the first construction materials for mankind, thanks to which, for long periods, he solved multiple problems of a structural nature. This is why this type of extremely low-cost energy material was chosen which, unlike other “energy-consuming” materials such as steel or reinforced concrete, may be re-employed in the production cycle once it is no longer in use.

The principal factors which convinced us to choose a wooden structure, rather than a traditional reinforced cement or masonry building are:

Speed of execution;

Low energy consumption,

Absence of mould and condensation phenomena,

Heat bridges practically absent;

Eco-compatibility of the materials;

Healthiness of the indoor environment;

Thermal-hygrometric gradient almost constant by means of CMV (Controlled mechanical ventilation);

Reduced horizontal seismic action thanks to the reduced structural masses in play.

Framed buildings have ancient origins. The modern version of this system presumes the creation of a structural cage with post and beam elements connected to each other through carpentry joints but also increasingly often using mechanical connection elements such as screws, bolts, pins, steel post shoes, and steel plates. With this construction method one may create buildings of three or four floors and allow much freedom in the management of internal spaces. Unlike structures framed with other materials, such as reinforced cement and steel, with wood there are no real interlocking joints due to the deformability and the variations in size of the wood. For this reason the structural mesh needs to be hardened to render the structure capable of absorbing horizontal action, such as wind and earthquakes, in order to then transmit them to the foundations.
