Steel Fixing and Reinforcement Insurance

Everything about steel fixing liability rests on a single moment: the inspection before concrete arrives.

Once a pour happens, the reinforcement is permanent and invisible. A bar omitted, bars at the wrong centres, laps shorter than specified, links missing, the wrong diameter used, cover too small or too large, or steel displaced during the pour produces a structure that cannot be assessed without destructive investigation. The failures surface as deflection, cracking, or corrosion staining years later, and by then the remedy is breaking out structural concrete, propping, replacing steel and recasting, with everything above it affected.

So the inspection record is the entire defence. A pre-pour check signed by the fixing contractor and by whoever is accepting the work, covering bar sizes, spacing, laps, links and cover, with photographs of each element before the pour. Where an engineer or clerk of works inspects, keep their sign off. Where a pour proceeds without an inspection because the programme demanded it, record that in writing. A fixer who can produce photographs and a signed check is in a completely different position from one relying on the fact that it has always been fine.

There is one steel fixing error whose consequence arrives so late that nobody connects it to the work, and it is extremely expensive.

Concrete protects reinforcement from corrosion, and the thickness of concrete between the bar and the surface is what provides that protection. Insufficient cover, because spacers were too small, too few, or displaced during the pour, lets chlorides and carbonation reach the steel sooner. The bar corrodes, expands, and bursts the concrete around it. In a car park, a bridge, a balcony or a marine structure that process is well documented and the remedy is concrete repair across an element or a structure.

Which makes spacers and their placement a far more important detail than their cost suggests. Correct spacer type and size for the specified cover, enough of them, placed so they cannot be displaced, and checked at the pre-pour inspection as a specific item rather than assumed. Record it. It is also worth knowing that this is the defect most likely to generate a claim a very long time after the work, which makes continuity of liability cover and the retroactive position on any professional indemnity worth attention.

Before concrete arrives, reinforcement is a tall, heavy, freestanding lattice, and it behaves like one.

A wall or column cage stands on its own, sometimes several metres high, tied together but not restrained, with people working beside and inside it. Wind, a knock from plant, an unbalanced section, inadequate temporary restraint, or a lift placing a prefabricated cage badly can bring it over. The weight is substantial and the structure is made of steel ends, so the injuries are crush and penetration rather than bruising. The same applies to stacked bundles of bar, which roll.

So the temporary stability is a design question rather than a site improvisation. Restraint and propping specified for cages above a stated height, prefabricated cages lifted with a method that keeps them stable, wind considered on exposed sites, a rule about nobody working inside an unrestrained cage, and bundles stacked and chocked rather than leaned. On a frame job, agree with the main contractor who provides the temporary restraint, because that gap is where the argument happens after a collapse.

The employers' liability exposure in this trade is constant, mundane and occasionally catastrophic.

A steel fixer spends the day handling cut bar: sharp ends, tie wire, heavy bundles, repetitive tying, bending and lifting, in excavations, on decks and at height. The everyday injuries are cuts, hand and eye injuries, back and wrist problems from repetitive work, and crush injuries from bundles. The catastrophic one is impalement: projecting starter bars and vertical steel left uncapped, which has caused fatal and life changing injuries when somebody has fallen onto them.

So capping is not optional and insurers treat it that way. Caps fitted to all projecting and vertical bars as a rule, maintained as the work progresses rather than fitted once, edge protection where there is a fall risk above exposed steel, gloves and eye protection appropriate to the work, mechanical handling for bundles rather than manual lifting, and rotation on heavy tying work. Expect to be asked about capping specifically, because it is the single control that distinguishes a managed reinforcement operation from an unmanaged one.

Work that cannot be inspected again is the question. We are an FCA regulated broker and will not tell you we are the best choice. These are the questions that decide it.
