RSJ and Steel Beam Installation Ware

GS Renovation installs RSJs and steel beams in Ware, working to calculations produced by a structural engineer we appoint. We prop the floor first, take the masonry out in stages, then seat the beam on padstones sized by the engineer. Building control applications and inspections are coordinated for you, and quotations are free and without obligation.

For Ware, on London-derived ranges a steel beam for one opening typically costs £1,500 to £4,000 fitted and signed off, or £2,500 to £6,500 or more for a full knock-through with the engineer's fee and making good; Hertfordshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Ware.

How the job runs

1. Free site survey at your Ware address and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Hertfordshire Building Control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. Props go in, the opening is cut and the beam is set on padstones, packed tight above.
4. Building control inspects the steel before it is covered. We make good, and the completion certificate follows.

Getting a steel beam into the historic core

Access is the first thing to settle on a steel job in the older part of Ware. The Ware Neighbourhood Plan records that the historic core is recognisable for its narrow streets, burgage plots and yards, and that original cobbled road surfacing still exists in parts. That layout decides how a beam reaches the opening. It also decides whether a single long section can be carried in at all, or whether the engineer needs to design the opening around two shorter beams bolted together.

We survey the route before the beam is ordered, not after it arrives on a lorry. That covers the gateway, the passage width, the turning point inside the house and the surface the beam is rolled across. Where cobbled surfacing is present it is protected and the load is spread. Getting this wrong is expensive, because a steel that cannot be delivered has to be recut and refabricated.

Housing in Ware

Of the 8,980 homes the valuation list records in Ware, 12% were built before 1919, 8% between the wars and 79% since 1945; 34% are flats and 66% are houses. Semi-detached houses make up 27% of homes here, and a beam bearing on the shared wall of a semi in Ware means one party wall notice.

What the bearings actually sit on

The beam sits on padstones in the existing walls rather than on the bedrock, but the ground still matters to the engineer. The British Geological Survey maps the bedrock beneath Ware as the Lewes Nodular Chalk Formation and the Seaford Chalk Formation, recorded as undifferentiated chalk. BGS mapping shows the same chalk bedrock across the town. Chalk is a competent bearing stratum, which is one reason an engineer may accept an existing footing for a new point load.

A steel beam changes how load reaches the ground. A wall spreads its load along its length. A beam collects that load and delivers it at two points instead. The engineer checks whether the masonry and the footing under each bearing can take that concentration, then specifies a padstone, a pier or a new pad foundation. We build what the calculations say, and we do not substitute a smaller padstone to save a course of brickwork.

Beams in converted malting buildings

A malting was not built to house proportions, so a beam inside one is a different design problem. South Maltings on Watton Road is Grade II listed and dates from around the late 1840s. It is built of Flemish bond yellow stock brick, with weatherboarded timber framed east and west ends under a pantile roof with gabled ends. A wall that is brick at one end of a building and timber framed at the other will not accept the same bearing detail throughout.

A building of this type may already have been restrained during its working life. The south range of the New Road maltings, converted to an art centre, carries cast iron circular tie plates marked Chas. Wells Ware. Those plates are evidence that the building was tied and restrained while it was still working. Cutting a new opening in a building that is already tied is work for the engineer to specify in full, including what happens to the tie, before anything is broken out.

Who inspects the steelwork

Building control for Ware is delivered by Hertfordshire Building Control Limited on behalf of East Herts District Council. East Herts states that the company is owned by East Herts Council along with seven other Hertfordshire local authorities. It provides plans assessments and site inspections, and applications can be submitted online through the Hertfordshire Building Control Planning Portal. Its operations team can be reached on 01438 879990.

We make the application and book the inspections as part of the job. The critical visit is the one taken while the beam is seated and the bearings are still open to view. Nothing is boxed in, boarded or plastered over a bearing before it has been seen, because uncovering it afterwards costs time and money. The completion paperwork is the document a buyer's solicitor asks for later.
