Post-Tensioned Structural Slab & Long-Span Coordination
Coordinating column-free open spaces, ultra-thin floor slabs, and dramatic overhangs through post-tensioned concrete engineering.
Vast, column-free living spaces that open uninterrupted to panoramic views require advanced structural gymnastics. Rowui coordinates post-tensioned (PT) concrete slab engineering with specialist structural consultants. By utilizing high-strength steel tendons tensioned after concrete pours, we eliminate bulky interior columns, reduce slab thicknesses to an ultra-slender minimum, and accommodate recessed door tracks and flush ceiling reveals.

Scope & Core Competencies
Our approach to post-tensioned structural slab & long-span coordination integrates architectural theory, physical constructability, and regulatory code requirements.
- Architectural coordination of post-tensioned (PT) high-strength cable tendon profiles
- Elimination of interior load-bearing columns and obstructive drop beams
- Slab thickness minimization maximizing finished interior floor-to-ceiling heights
- Seamless integration of recessed sliding door pocket tracks into the concrete slab
- Tendon anchor pocket coordination and long-term corrosion protection details
- Vibration and acoustic deflection criteria coordinated with luxury standards
- Coordination with local Structural Engineers of Record (SEOR) for construction sign-off
Modern residences requiring expansive column-free great rooms, subterranean garages, and slender cantilevered terraces.
