Suspended slab under construction, with the formwork still in place Suspended slab formwork and rebar in place, ready for concrete pour.. A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete.
Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
This process may occur in three different approaches, however the basic method is the same in each: In situ: Formwork construction and pouring of concrete occur on site, then the slab is assembled (if required). [4] Precast: The slabs are made somewhere else and then brought to the site and assembled. [4]
The slabs are typically 120 cm wide with standard thicknesses normally between 15 cm and 50 cm. Reinforcing steel wire rope provides bending resistance. Slabs in prestressed concrete are usually produced in lengths of up to 200 meters. The process involves extruding wet concrete along with the prestressed steel wire rope from a moving mold. The ...

The list of construction methods covers the processes and techniques used in the construction process. The construction method is essential for civil engineers; utilizing it appropriately can help to achieve the desired results. The term building refers to the creation of physical structures such as buildings, bridges or railways. One of the ...
In 1935 W.A. de Vigier designed an adjustable steel prop which revolutionized many aspects of the construction industry including to support slab formwork, wall formwork, trench sheeting and falsework. [3] Materials from which falsework systems are manufactured have also diversified from traditional steel and timber to aluminium components.
Suspended structures often allow much light to enter, because of the unobstructed interior. [5] A cable suspended structure: Yoyogi National Gymnasium in Tokyo. An example of a catenary-shaped suspended structure is the Eero Saarinen designed Dulles International Airport. The roof of the structure is made up of suspension cable which stretches ...
