In the case of long span truss work, bearing lengths of at least 3" are quite common. Trusses span greater distances than framed floor assemblies and can be designed to span the entire building, eliminating center load bearing supports. They are moderately more expensive than framed floor assemblies, but provide a remarkably strong floor with little deflection or "bounce" to it. Another advantage to this type of structural system, is that utility installations can be run between the webwork components. Never allow trades to cut or drill into the members of a truss, for they are manufactured precisely for the loading conditions they will undergo during the life of the building.
Fourth, factor in the cost of refinishing the floor later or doing touchups. This is a whole another article. Some finishes can be spot touched up like some of the oils while others require a full sand over the whole floor. Some finishes require a professional installer and may have extreme odor during the cure. If you live with the floor for very long, factor these decisions in for the type of finish to choose for lifetime durability and the cost & effort to refinish.
Many people also have questions about the tiles durability and use. Interlocking floor tiles are usually placed on the floor underneath it, meaning there is no adhesive or floor base. Some may become concerned that the interlocking tiles will become loose easily due to the lack of adhesive. This is not the case. Tile floor systems are designed to lock together permanently. When appropriately installed, the interlocking floor tile should remain exactly as it was placed until the user decides to move it. Interlocking tile floors are appropriate for any use, from industrial to residential. This interlocking flooring system does not have as much risks compared to traditional tile flooring.
