Post-Tensioned Structure Engineering

Prestressed concrete design that unlocks longer spans, thinner slabs and leaner structures — engineered with rigour and built with confidence.

Engineering longer spans with less material

Post-tensioned structures put concrete to work before the load ever arrives — a controlled prestress that lets the same material span further, sit thinner and crack less, transforming what a floor plate or a transfer structure can achieve.

By tensioning high-strength tendons against the hardened concrete, we hold the member in permanent compression and balance much of the gravity load before it can develop tension. The result is longer spans, shallower sections, leaner reinforcement and far tighter control of deflection and cracking — efficiency engineered into prestressed concrete from the outset.

What This Service Covers

From PT slabs to complete prestressed structures

PT Slab Design

Bonded and unbonded post-tensioned slabs — flat plate, banded and hybrid forms — designed for clean soffits, minimum depth and tight crack control.

Transfer Structures

Post-tensioned transfer beams and plates carry very high concentrated loads across open space below while keeping deflection and depth in check.

Long-Span Floors

Prestress keeps depths economical and deflections controlled, opening large, uninterrupted floors free of forests of columns or deep beams.

Parking Structures

Long, column-light bays with crack control engineered to protect an inherently exposed deck from water and chloride ingress over its life.

Commercial Buildings

Open, adaptable floor plates with generous clear spans and minimal depth that maximise lettable space and floor-to-floor efficiency.

Industrial Buildings

Wide-span, heavily loaded floors and supporting structures that stay efficient while keeping member sizes and material quantities disciplined.

PT Applications

Where post-tensioning earns its place

Flat plate & banded

Slabs & Floors

PT slabs and long-span floors deliver column-free, slender plates with flat, durable surfaces and the depth economy conventional concrete cannot match.

Columns over open space

Transfer Structures

Post-tensioned transfer beams and plates redistribute heavy column loads over lobbies, retail floors and basements within a controllable depth.

Durable & heavy-use

Parking & Industrial

Long, manoeuvrable bays and wide, heavily loaded industrial floors where crack control and durability protect the structure in demanding service.

Tendon profiling, honest accounting of prestress losses and long-term durability are engineered as primary concerns — so each structure achieves its efficiency without compromising safety, serviceability or constructability.
