Which materials are specifically not covered by the Quality Control plan?

The materials that are specifically not covered by the Quality Control plan include sods and sealers. This distinction is important because the Quality Control plan primarily focuses on materials that have a significant impact on the structural integrity and durability of construction projects, such as concrete and steel, asphalt, and wood.

Sods and sealers generally pertain to landscaping and surface treatments rather than the core structural elements of construction. While they may have their quality considerations, they do not undergo the rigorous quality control processes that are applied to the major structural materials. This is because sods relate to landscaping and aesthetic aspects, and sealers are typically used for surface protection rather than forming part of the essential load-bearing characteristics of a structure. Thus, the Quality Control plan is designed to address materials that directly affect the safety, strength, and longevity of construction projects, excluding items that are more peripheral or auxiliary in nature.
