Structural formwork plan for the ground floor of a residential building, featuring C30 concrete (30 MPa) with a/c ratio <0.60.
Key Structural Components
The drawing indicates column continuation methods with specific hatching patterns for columns that continue upward, terminate, or begin at this level. Includes detailed slab specifications with thickness indicators (h=12cm for maciça/solid slabs) and beam elevations relative to the zero reference level (elev = +0.30). Technical Specifications: Designed for Environmental Aggressiveness Class II (urban region) with defined concrete cover requirements: 2.5cm for beams and columns, 2.0cm for slabs and stairs, and 3.0cm for foundations. Concrete slump of 12±2cm using aggregate size 1.
Construction Notes
Includes formwork removal guidelines: lateral forms can be removed after 3 days, bottom forms after 10 days (with 50% shoring maintained until 28 days). Proper curing requirements specified for the first 7 days, maintaining moisture or using impermeable film protection.
