Upload by Adam

List of architectural and construction abbreviations used across drawings, followed by an OBC reference data matrix for existing-building renovation scope. The OBC section specifies project type as renovation to an existing elementary school, including change-of-use and building classification criteria. It records major occupancy classification for elementary school (group A2), occupant load by floor/level, superimposed major occupancies, and the building area in square meters. It also includes hazard, importance, and construction index placeholders plus performance-reduction items such as structural and plumbing, marked as no changes.
