Animation depicting construction of multi-story building using aluminum handset formwork. Steel and plywood formwork for poured in place concrete foundation. Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1]
Waterproofing an existing basement begins with excavating to the bottom sides of the footings. Once excavated, the walls are then power washed and allowed to dry. The dry walls are sealed with a waterproofing membrane, [3] and new drainage tiles (weeping tiles) are placed at the side of the footing.
In monolithic architecture, large parts of the building are made of concrete; in insulating concrete form construction, the concrete walls may be hidden with an exterior finish or siding. Inside the structure, a single Lally column , steel basement jack, wooden column or support post may hold up the floor above in a small basement.
By the end of the month, the concrete had been poured for the floor of the tower's basement level B3.

Once the site is prepared and the utility lines installed, a foundation of reinforced concrete is poured. The walls are then installed. Usually, they are either poured in place or formed either on or off-site and then moved into place. Reinforced concrete is the most common choice. The process is repeated for the roof structure.
No-fines houses were built with a ten-inch (254mm) concrete shell cast in situ. [1] The concrete for the entire outer structure was cast in one operation using reusable formwork. The ground floor was either concrete or traditional timber joists and floorboards; the first floor was made with traditional timber joists and floorboards.
To accelerate the building's construction, a concrete plant was built in the building's basement, allowing workers to pour one-third of a concrete floor every day. Contractors built two temporary kitchens on the site for workers, and telephone and loudspeaker systems were installed on every floor to allow workers to communicate.
