About this detail

These structural sections detail concrete basement walls extending from Level 01 down to Level B2 and foundation pile caps, incorporating vertical and horizontal reinforcing steel. The basement walls feature number six bars at eight inches horizontal each face and number six bars at twelve inches vertical each face, tied with u-bars matching the wall vertical reinforcing. Slab-on-grade connections include extended slab reinforcement developed into the pile cap with required splice lengths or hooked development lengths, alongside optional concrete fill at construction joints. Pile cap reinforcement is specified per schedule and supported by drilled shafts where applicable, with temporary shoring indicated by others. Level elevations are marked for Level 01 at zero feet, Level B1 at minus thirteen feet, Level B2 at minus twenty-one feet six inches, and the bottom of the service elevator pit at minus twenty-three feet.
