Built from the core out
The core climbs two levels ahead of the slabs on its own hydraulic rig. Tables fly up behind it, pods go in as each deck is poured, and the envelope follows six floors below. Nothing waits for anything else.
What we do
Four ways to get your tower up.
Appoint us as construction manager, general contractor or specialist core contractor — or bring us in at concept to make the structure buildable at speed.
Construction management
Open-book trade packages, one programme and a site team that runs the gates, cranes and hoists for you.
- Fee on cost, shared savings
- Trade package procurement
General contracting
Lump-sum or GMP delivery of the whole building, from shoring to handover, with one point of responsibility.
- Fixed price or GMP
- Bonded, insured, warrantied
Self-climbing cores & jumpform
Our own hydraulic climbing rigs and crews pour a core level every three days, independent of the crane.
- Three-day core cycle
- Screens with full edge protection
Preconstruction & modular
Buildability reviews, logistics plans and factory-finished bathroom pods that cut weeks from every floor.
- Cost plans in 10 days
- Pods tested before lifting
The six-day floor cycle
One floor. Six days. Every week.
A typical floor of a residential tower, from setting out to concrete — the rhythm every trade on our sites plans around.

Safety
Fast is only fast if everyone goes home.
Speed on our sites comes from planning, not pressure. Every lift is planned the day before, every worker can stop the job without asking, and every near miss is reported, logged and fixed within 24 hours.
