HALDEN

Preparing the sequence00
Structural craft since 1994

We buildthe frame

Everything else depends on it. Halden takes a building from excavation to handover, and stays on site until the last bolt is torqued.

FRAME 001 / 289EXCAVATION

Concrete hasno forgiveness.

Halden is a structural contractor. We pour, we frame, we set tolerances that architects can design against. Thirty one years in, we still measure twice on a Sunday.

The studio works with nine in-house disciplines. Engineers sit next to the site teams, so a detail that fails in the field gets redrawn the same afternoon.

What weactually do

Structure

Frame and foundations

Ground investigation, raft and pile design, post-tensioned slabs. We model the structure before the first excavator arrives, then we build what we modelled.

  • Geotechnical survey and settlement modelling
  • Reinforced and post-tensioned concrete frames
  • Steel connections detailed in-house
Concrete

Formwork and finish

Fair-faced concrete is a one-take discipline. Panel layout, tie positions and pour sequence are agreed with the architect before anything is cast.

  • Board-marked and smooth fair-faced casting
  • Mock-up panels approved on site
  • Mix design tuned to local aggregate
Envelope

Skin and openings

Stone, timber and glazed systems set against the frame. Tolerances are carried through from structure to facade so nothing is packed out at the end.

  • Dry-laid stone and ventilated facades
  • Slimline structural glazing
  • Thermal and water testing before handover
Delivery

Site management

One team from excavation to the final walk-through. The site manager who signs off the raft is the one who hands you the keys.

  • Single point of contact for the whole build
  • Weekly progress film and cost report
  • Twelve month defects support

Survey

We measure the ground first

Boreholes, laser scan and a settlement model. If the ground argues with the drawings, we find out in week one and not in month nine.

Frame

The structure is the schedule

Pour sequence drives everything downstream. We publish it early so the trades that follow can plan against a real date.

Envelope

Tolerances carry through

Facade setting-out comes off the surveyed frame, not the design model. Nothing gets packed out to hide an accumulated error.

Handover

We stay after the keys

Twelve months of defects support with the same site manager. Buildings settle, and someone who knows the pours should be the one to look.
