After completing the NASH Columbia University Bulletin 11 markups, the project progressed into the construction phase. As part of a site visit led by the project manager, various errors were discovered. I was then assigned the responsibility of rectifying these issues, incorporating the project manager's feedback and survey results. This valuable experience significantly contributed to the enhancement of my drafting skills, the deepening of my architectural knowledge, and the improvement of my time management abilities. It provided an excellent opportunity for me to further develop my expertise in resolving on-site discrepancies and ensuring the smooth and precise progression of the project.
