Steel fixing & concrete — full packages.

A4 Construction Ltd supplies specialist labour and subcontract packages for reinforcement and concrete. From bar schedules to pour day, we work to drawing, programme and inspection standards.

01 · Primary service

Steel fixing

We cut, bend, assemble and fix reinforcement for foundations, columns, beams, walls, slabs and stairs. Work is carried out from structural drawings and bar bending schedules, with cover, spacing, lap lengths and tying methods checked before inspection.

Cutting and bending to schedule (links, stirrups, shaped bars)
Cage assembly for columns, beams and pile caps
On-site fixing of bars and mesh with chairs and cover blocks
Starter bars, kickers and congested detailing
Inspection-ready presentation for engineers / clerk of works

02 · Primary service

Concrete works

Formwork, placement, compaction and finishing for structural and groundworks elements. We plan pour sequence around access, plant and weather so the reinforcement package is protected and the finished surface meets the specification.

Traditional and system formwork — walls, columns, beams, foundations
Skip, pump or chute placement with agreed pour sequence
Poker vibration, screeding and surface finishes
Curing support and early-age protection
Coordination with steel fixing so pour dates hold

03 · Combined packages

RC packages under one team.

Many contractors prefer one specialist for both fixing and concrete. We own the interface — so bars, formwork, inspection and pour logistics stay aligned.

Single point of contact

One supervisor coordinating steel fixers and concrete gangs against your programme.

Fewer handover gaps

Less risk of “not our package” delays between reinforcement and pour.

Clear programme ownership

Fixing completion, inspection windows and pour dates managed as one sequence.

What information do you need to price a package?

Structural drawings, bar schedules where available, programme dates, site location, access constraints and whether you need labour-only or a fuller package.

Which project types do you cover?
