POST-TENSIONING DESIGN SERVICES

Precision Engineering for High-Performance Structures

At Skyscraper Creators, we provide post-tensioning design services for slabs, beams, podium decks, bridges, and complex structural systems. Our PT solutions improve structural efficiency, optimise material usage, and enable longer spans with thinner profiles without compromising strength and serviceability.

We support both domestic and international projects with comprehensive design assistance, including anchor layout planning, cable profiling, stressing sequences, and construction-friendly detailing.

Working closely with consultants, contractors, and project teams, we develop PT design solutions that are:

  • Structurally sound and code-compliant
  • Economically optimised
  • Easy to install and stress on site
From commercial towers, industrial facilities, and multi-level parking structures, our post-tensioning expertise supports efficient, reliable, and practical structural solutions across a wide range of applications.

Our deliverables include

Our post-tensioning design documentation is prepared in accordance with PTI and Eurocode standards, supporting accurate coordination across design, construction and project management teams throughout the project lifecycle.

POST-TENSIONING FUNDAMENTALS

What is
POST-TENSIONING?

Prestressing is defined as the precompression of a concrete element (typically through steel wires or strands), such that when flexing under applied loads, the concrete element still remains in compression. Concrete functions best under compression and is brittle in tension. Thus, prestressing is introduced to compensate for the tensile stresses experienced by a concrete element, thereby providing a more efficient design. There are two methods of prestressing.

Prestressing

Prestressing is the process of introducing pre-compression into a concrete element using high-strength steel wires or strands, so that the member remains primarily in compression under service loads. Since concrete performs well in compression but is weak in tension, prestressing helps counteract tensile stresses and improves overall structural efficiency. It is commonly achieved through two methods: pre-tensioning and post-tensioning.

Pre-tensioning

Pre-tensioning is a method where concrete is cast around previously stressed steel strands. As the concrete hardens, it bonds with the strands. Once sufficient strength is achieved, the strands are released, transferring the stresses into the concrete. This method is commonly used in precast concrete elements where fixed abutments or rigid moulds resist the prestressing force.

Post-tensioning is widely used in structural engineering to reduce slab thickness, enable longer spans, and increase usable floor areas in buildings. It is commonly applied in both building and bridge construction, improving structural efficiency and overall design performance.

Advantages of prestressed (Post-tensioned) floors

The primary advantages of Post-tensioned floors over conventional reinforced concrete in-situ floors are as follows:

Design
  • Increased clear spans (so reduction in number of columns)
  • Thinner slabs
  • Lighter structures (reduced floor dead load)
  • Reduced storey height
  • Flexible layout
  • Aesthetically pleasing
Performance
  • Deflection reduction
  • Reduced cracking/crack-free
  • No additional fire protection required
  • Vibration control
  • Large reduction in conventional reinforcement
  • Better water resistance
Service
  • Distribution of services (avoiding usage of downstand beams)
  • Accommodating openings without much difficulty
  • Tendons can be diverted to avoid larger openings
  • Tendon positions can be marked on slab’s soffit/located using C.A.T cable detection equipment
Operation
  • Robust
  • Vandal resistance
  • Durable
  • Adaptable during structure’s lifespan
Construction
  • Fast construction programme
  • Rapid mobilisation
  • Reduces reinforcement congestion
  • Larger area pours compared to normal reinforced concrete
  • Reduced crane usage time
Sustainability
  • Minimises the impact of raw material transportation (minimises use of concrete and uses high-grade steel for tendons)
  • Both concrete and steel tendons from demolished floors are recyclable
  • Less material used and therefore less carbon footprint
