Precast concrete is ideally suited for all types of utility structure applications including electrical, gas, industrial, telecommunications, renewable-energy structures, and water and wastewater structures. Precast concrete, Concrete cast into structural members under factory conditions and then brought to the building site.A 20th-century development, precasting increases the strength and finish durability of the member and decreases time and construction costs. Hubert Bachmann, Department Manager Ed. The system was developed in Kyrgyzstan in 1975. PRECAST CONCRETE: Precast concrete is a construction product produced by casting concrete in a reusable mould or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place. Precast Concrete is used for parking garages, office buildings, bridges, stadiums, shops and housing repetitive and modular elements and structures. The precast concrete components are later transported to the construction site where they are assembled by cranes, which will lift the precast elements to their final position (Figure 1). There are many sizes in between. A Precast/Prestressed Concrete Institute free AIA-CEU approved education webinar on the versatility of incorporating precast, prestressed concrete in the design and construction of parking structures. For example, if a structural wall is to be dismantled for modification it will impact the overall stability of the structure. The hybrid composite precast frame is itself a hybrid composite structural system that maintains the advantages of both precast concrete structures and steel frames.
