The 4 pictures above show a typical floor installation for an indoor wooden basketball court. The contractor does not need to follow these specific designs for the floor, except the thickness of the surface wood boards that shall be minimum of 22 mm and provided with tight joints (not similar to existing flooring to be removed) and other requirements described in the paragraphs above.

No payment will be authorized for any wood flooring until the manufacturer technical representative certifies the correct surface preparation and the correct installation of the new flooring.

- Ventilation: The gymnasium used to have ceiling openings that were covered by the school administration long ago to avoid water infiltration problems. This makes the ventilation of the gymnasium inadequate. The contract includes the design of a new ventilation system in coordination with the heating system. The work shall include the following:
