DEMO SITE CONSTRUCTION AND DECONSTRUCTION

CONSTRUCTION OF DEMO SITE IN ITALY

 

CONSTRUCTION OF DEMO SITE IN SPAIN

 

DECONSTRUCTION OF DEMO SITE IN SPAIN

The building was dismantled following the reverse sequence to its construction to remove building parts (element by element):

1. Electricity, hardware and sensors installed for monitoring 
2. Doors and windows 
3. Timber internal partition wall
4. Linings (walls and floor)
5. Stairs
6. Roofing
7. Cladding (Extruded tiles and wood insulating panels)
8. Remove the mortar grouting of joints and connections with a pneumatic drill and a hammer
9. Remove the concrete frame and set of bearing and non-load bearing prefabricated wall (façade) elements by unscrewing the bolts of the connections and uplifting the elements with a telescopic crane in the following order:
 

Solid roof slabs (2 pieces)
First floor beam (L-section)
First floor sandwich panel
First floor wall panel (the biggest one, with door and window)
First floor timber wall panel
First floor beam (square-section)
First floor wall panel (the smallest one, just with window)
Solid floor slabs (2 pieces)
Ground floor beam (L-section)
Ground floor sandwich panel
Ground floor wall panel (the biggest one, with door and window)
Ground floor beam (square-section)
Ground floor wall panel (the smallest one, just with window)
Block wall
Column

10. Remove the steel plates attached to the removed elements by unscrewing the bolts and uplifting them with a telescopic crane

 

Time needed for the disassembly with average 3 workers working full time:

  • steps 1 to 8 -> 3 days
  • steps 9 to 10 -> six hours
