A new construction project with a building area of 1500m2, consisting of two underground floors and five above ground floors, and a reinforced concrete frame structure.
There are 3 post tensioned prestressed concrete beams in the lobby on the first floor.
After 25 days of pouring, the production manager judged based on experience that the concrete strength had reached the design requirements.
Immediately, the operators were arranged to remove the beam bottom formwork and prepare for prestressed tensioning.
