1, basic requirements:
Civil engineering should be waterproof during floor construction, and the foundation construction requirements are as follows:
(1) One felt and two oils waterproof layer.
(2) For concrete with a thickness of 2) 100mm, portland cement of grade 32.5 or above should be used, the aggregate particle size should not be greater than 15mm, and the surface strength grade of concrete should not be lower than C 15.
(3) Before the wooden floor construction of basketball court, the civil engineering must be completed and cleaned, and the construction of sports floor can only be carried out after the ground construction quantity meets the design requirements. (The foundation flatness is high, and the basis difference is not more than 5mm)

2, indoor water, electricity, steam ventilation and other installation projects are over, especially the water network pipeline must meet the design requirements through pressure test, and normal use will not affect the wooden floor (no water leakage).
3, indoor decoration ceiling, sound reinforcement, electroacoustic, lighting and other projects ended, so as to avoid cross construction caused by wood floor construction and security risks.

4. The ground humidity or equilibrium moisture content is basically consistent with the outside world.
5, in the case of night construction, must have the lighting conditions of night construction.
