ACI 351 emphasizes that even "static" equipment can transmit significant forces during startup, shutdown, upset conditions, or thermal cycling. Therefore, the foundation must remain rigid, durable, and dimensionally stable over decades of service. ACI 351
Many foundation failures occur not from poor design but from poor construction. ACI 351.1R dedicates significant text to construction tolerances that are far stricter than those for ordinary concrete. Top-of-foundation elevation tolerances are often ±1.5 mm over a meter. Formwork must be braced to prevent movement during concrete placement, and concrete placement must be continuous to avoid cold joints within the inertia block—a cold joint becomes a plane of weakness for vibration transmission. Therefore, the foundation must remain rigid, durable, and
Continuous slabs-on-ground (or pile-supported) used for machinery like machine tools or when multiple equipment pieces are grouped together.
A properly designed foundation per ACI 351 consists of several integrated subsystems. Failing to address any one of them can compromise the entire structure.
