Sayram Hybrid Construction Solutions
A Core Housing System. Three Deployment Packages. One Turn-Key Partner.
5 Floors in 5 Days —
and still monolithic.
Sayram has pioneered the tunnel formwork system in Turkey since the 1980s. Now, by combining in-situ tunnel formwork with prefabricated precast and POD systems, we deliver a hybrid construction methodology that is structurally superior, measurably faster, and cost-proven — at any scale.
This is not a system licence. Sayram supplies the steel forms, cycles the formwork, and stands behind the finished structure — as a full turn-key partner.
Watch the Sayram Hybrid System in Action
See how our tunnel formwork and hybrid construction methodology delivers complete floor cycles in just 24 hours — from formwork positioning to concrete pour and strip.
- Full wall and slab cast in single operation
- Smooth off-shutter finish — no plastering required
- Precision steel formwork with 500+ reuse cycles
- Integrated MEP coordination on-site
A Core Housing System. Three Packages.
Every project context is different. Sayram Hybrid Construction Solutions is designed to flex — from fully standardised high-volume delivery to integrated technology partnership within existing contractor structures.
A fully optimised turnkey solution for high-volume housing programmes. The same proven floor-plate, the same formwork cycle, delivered faster and cheaper on every successive block. Ideal for national housing authorities and large-scale urban developments.
- One floor poured every 24 hours
- Up to 500 reuses per formwork set
- No plastering required — smooth off-shutter finish
- Up to 40 storeys applicable
- Proven in seismic zones — no structural damage in 1999 Marmara earthquake
The hybrid approach: in-situ tunnel formwork for structural cores, precast/POD for kitchens, bathrooms and façade panels. This combination enables faster completion of repetitive elements while giving architects the freedom to differentiate unit types and facade treatments.
- Up to 40% shorter overall build programme
- 20–40% reduction in on-site manpower
- 3–5% capex saving vs. conventional methods
- ~50% fewer snagging items at handover
- Modular POD bathrooms: factory quality, site speed
Sayram acts as a construction technology partner within your existing contractor or JV structure. We supply, erect and cycle the tunnel formwork system — and where it adds value, introduce precast components — without displacing your existing project team.
- Technology transfer and on-site training
- Works alongside any main contractor
- Suitable for phased large-scale projects
- Scalable from single block to 1,000+ unit masterplans
- Full technical support through project lifecycle
Erciyes Housing Complex, Mersin Erdemli
The Erciyes Housing Site pilot demonstrated the scalability of the hybrid tunnel formwork and precast system. Delivered in significantly shorter construction times compared to conventional methods.
Erciyes was the proof of concept for Sayram Hybrid Construction Solutions at scale. The project combined in-situ tunnel formwork for structural walls and slabs with precast staircase elements and factory-produced bathroom pods, cutting the overall programme by up to 40% compared to traditional methods.
The smooth off-shutter concrete finish eliminated plastering entirely. Handover snagging was reduced by approximately 50%, and on-site manpower requirements were 20–40% lower than a conventional reinforced concrete frame. The project validated every core metric now used to position the Sayram system for international housing programmes.
The Erciyes case study was selected for the WUF13 Practice Hub by UN-Habitat as a validated, scalable model for affordable housing delivery. WUF13 drew 20,779 registered participants from 174 countries — with 88% from Asia and Africa, the primary markets for large-scale housing programmes.
System Advantages
Economical
Up to 500 reuses per steel formwork set dramatically lowers per-unit cost on large programmes. No timber. Minimal waste.
1 Floor Per Day
Walls and slabs cast simultaneously in a single operation. Structural frame complete in days, not weeks.
Earthquake Resistant
Monolithic reinforced concrete construction. Buildings using tunnel formwork sustained zero structural damage in the 1999 Marmara earthquake.
No Plastering
Smooth off-shutter concrete surface eliminates plastering entirely. Reduces finishing programme and cost.
Eco-Friendly
Zero timber consumption. Monolithic construction reduces heating and cooling energy use by up to 30%.
