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
Project Fit & Suitability

Studio Methodology

The Step-by-Step Delivery Process

How we guide your post-tensioned structural slab & long-span coordination from initial brief discovery to completed execution documents.

Stage 01

Span & Clear Height Target Alignment

Establishing column-free living room dimensions and target ceiling heights.

Milestone Phase 1
Stage 02

Tendon Geometry & Core Wall Placement

Coordinating tendon paths with stair cores, elevator shafts, and cantilevered balconies.

Milestone Phase 2
Stage 03

Recessed Track & Penetration Detailing

Designing slab recesses for flush pocket doors and plumbing sleeves away from tendons.

Milestone Phase 3
Stage 04

Structural Coordination Drawing Sign-Off

Issuing architectural sets coordinated with structural engineer PT tendon layouts.

Milestone Phase 4

Informed Guidance

Frequently Asked Questions on Post-Tensioned Structural Slab & Long-Span Coordination

Detailed technical and procedural guidance regarding post-tensioned structural slab & long-span coordination commissions, contractor coordination, and building code compliance.

Post-tensioning allows significantly longer spans with 20% to 30% thinner concrete slabs, completely eliminating drop beams and interior columns for breathtaking open living spaces.
