Design And Construction With Long Span Solutions


Wandee Super Span ™ is a new formation that focus in long span construction in Pattaya. Our solutions include post tension concrete, steel and composite structure. 

CANTILEVER AND SPAN CONSTRUCTION


Excellent structures are mainly defined by demanding engineering. For a cantilever construction of up to 30 meter or column-free spaces of up to 60 meter in residential buildings, custom fabricated steel box girders and cellular beams offer the best performance for the task.


  • A cantilever is a rigid structural element that extends horizontally and is supported in just one end. Usually it extends from a pillar or concrete wall to which it needs to be attached. Like other structural elements, a cantilever can be built, for example, with a cellular beam, steel box girder or composite slab.


  • The distance between two pillars is referred to as a span. Until recently, a span of over 15 meter was considered difficult in Pattaya.

    Wandeegroup worked in the early 2000s with spans of up to 40 meter. Ideally, the cellular beam and steel plate were used.

RC AND POST-TENSIONED CONCRETE


Modern buildings are best built with a combination of reinforced concrete and post-tensioned concrete. Post-tensioning is used extensively in bridges, but also in residential construction for slab, column and wall. Wandee Super Span  integrate post tensioning in footing, wall, beam and floor slab.


  • Reinforced concrete (RC), also called reinforced cement concrete and ferroconcrete, in which steel is embedded in such a manner that the two materials act together in resisting forces. Reinforcement bars or mesh are incorporated to absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure.


  • Post-tension concrete (PT) is tensioned steel and compressed concrete, which means that both building materials are placed in their strongest conditions. Reinforcing cables (tendons) are laid inside ducts and tensioned after hardening of the concrete. These tendons are then grouted.

STEEL FRAME AND CONCRETE FRAME


Wandeegroup is proud to have built the first multistorey condominium building with a steel frame and composite structure in Pattaya. The steel carrier designed for this purpose with a depth of 900 mm was made by Siam Yamoto Steel. Wandee Super Span now offers steel frame design for the construction of  villas.


  • Steel frame is the undeniable choice for the seismic-resistant construction. Even when it comes to the most demanding projects such as bridges, high-rise buildings or villas with long spans, the steel frame construction has shown its ability to resist severe seismic events.


  • Concrete frame is heavier and has lower tensile strength compared to steel structures. Hence smart engineering is necessary to create seismic-resistant construction solutions. The construction of reinforced concrete structures is labor intensive.
