A rolled steel joist is only as good as what it lands on. In Stevenage that means establishing what the wall is built from, and what sits under each bearing point, before anything is cut. We appoint the structural engineer, build to the calculations issued, and coordinate the building control inspections.
Terraced houses set the beam spans in Stevenage
Terraced houses account for 19,720 dwellings, or 51.3 per cent of the borough's council tax stock, against 25.9 per cent across England and Wales. The single largest property category is the three bedroom terraced house, at 13,430 on the valuation list, and semi detached houses of all sizes number 4,680.
A mid terrace carries a party wall on each side and a shared structure beyond it. That changes how a beam is propped, where the ends can bear, and what the neighbours need to be told. The engineer's calculations settle the span, the section size and the padstone before any brickwork is opened up.
Concrete walls in Broadwater are not brickwork
Work began on the Broadwater neighbourhood in 1953, and the council records that some of the first houses built there were Wimpey no fines homes, cast by pouring concrete for the outer structure into large reusable moulds in one operation.
Poured concrete is not laid in courses, so it cannot be needled and propped as though it were brick. Load paths, temporary support and the bearing detail all have to suit the construction actually present. The engineer inspects the wall before issuing calculations, rather than working from a floor plan alone.
Who inspects the beam once it is in
Hertfordshire Building Control Limited does, because Stevenage Borough Council does not run its own building control service. The council owns that company jointly with seven other Hertfordshire local authorities. It takes inspection bookings by phone on 01438 879990 and by WhatsApp on 07483 034482.
We make the application and book the inspections, so the steel is seen before it is boxed in and plastered over. You are left with a record of sign off for the file, which matters when the house is sold.
