Rebar waste (RW), is the discrepancy between fabricated reinforcing bars (rebars) required for reinforcement in certain parts of the structure and the available commercial sizes from where it was bent or fabricated from. This is the initial RW. Somehow, this excess could still meet the requirements of other parts of the structure and therefore, it is reused, still as reinforcement. This is good because we still benefit from its cost, since it still serves its purpose, as reinforcement. However leftovers could still be recycled for other purposes. Those that are not recycled and cannot be used, as reinforcement anymore is useless already and it is termed as final RW. This thesis has two objectives. The first is to perform case studies on three (3) projects to be able to estimate the amount of RW produced on a per floor basis (Estimation Model). The second objective is to perform a survey on sixteen (16) projects to determine the most common causes of RW, most common means of preventing RW, most common means of reusing and recycling RW, and lastly the most common ways of disposing (along with its frequency) RW.
