Structural engineers in Northern Ireland

Structural engineering, calculations and surveys for homes, developments and commercial projects across Northern Ireland, delivered remotely nationwide with site visits arranged across the country.

Structural engineering across Northern Ireland

Northern Ireland ranges from the dense Victorian brick terraces and shipyard-era housing of Belfast, through the market towns and stone-built property of counties Armagh, Tyrone, Fermanagh, Down, Antrim and Londonderry, to modern estates and rural farmhouses across the countryside. Much of the older stock is solid brick or rubble stone with shallow foundations and slate roofs, while suburban Belfast, Lisburn and Derry carry post-war and modern cavity-wall housing. Each type raises its own structural questions, from removing a chimney breast in a Belfast terrace to extending a rendered farmhouse where the existing walls carry the roof and floor loads.

We provide the full structural remit for projects across Northern Ireland: Eurocode calculations and drawings for extensions, loft conversions, wall removals and new openings, structural surveys and defect reports, and design for new build and commercial work. Desktop calculations and reports are delivered anywhere in the province, and where a survey or inspection is needed we arrange attendance across the country, from Greater Belfast to Newry, Enniskillen and the north west around Londonderry.

Ground conditions across Northern Ireland

The geology of Northern Ireland is dominated by the basalt of the Antrim Plateau, which gives strong bearing but can hide weathered zones and, near Lough Neagh, interbedded clays and lignite. To the south and west, older sandstones, mudstones, limestone and the Silurian greywackes of Down and Armagh come through, while the drumlin belt across the centre leaves widespread glacial till and boulder clay in rounded ridges of variable stiffness. River valleys, the shores of Lough Neagh and the coast carry soft alluvium and peat that can call for deeper or engineered foundations.

We design foundations to suit the ground rather than assuming a standard depth, specifying strip, trench-fill, raft or piled solutions to match the bearing stratum and any soft or made ground. Where a ground investigation flags soft clay, peat or fill, we set the foundation depth and type to carry the loads safely so the structure stays still. On drumlin sites we check that bearing does not vary sharply across the footprint, and near the basalt escarpments and old quarries we look for rockhead close to the surface, which changes how a footing should be founded.

How we work with clients in Northern Ireland

Most structural work is done from your drawings, photographs and survey information, so being a service-area practice is rarely an obstacle for clients in Northern Ireland. We turn desktop calculations and reports around quickly and coordinate with your architect, builder and the local Building Control department so the structure and the design agree before work is priced on site.

Where a physical inspection is needed, for a survey, a movement assessment or a check of existing structure, we arrange a visit across Northern Ireland. Every output is tied to the Eurocodes and the Building Regulations (Northern Ireland) technical guidance and backed by professional indemnity cover, and the same standards let us support clients across the rest of the UK.

Questions

Common questions

Do you cover the whole of Northern Ireland?

Yes. We provide structural calculations, surveys and design across Northern Ireland, from Belfast and Lisburn to Londonderry, Newry, Enniskillen and the rural counties. Desktop work is delivered remotely and site visits are arranged across the country.

Do you need to visit my property in Northern Ireland?

Not always. Calculations for extensions, lofts and wall removals are usually prepared from drawings and photos. A visit is arranged where a survey, movement assessment or inspection of existing structure is needed.

Can you provide calculations for Building Control here?

Yes. We prepare Eurocode structural calculations and drawings to suit the Building Regulations (Northern Ireland) technical booklets, ready for your district council Building Control and written to be followed on site.

How quickly can you turn work around?

For straightforward domestic calculations we aim for a short turnaround once we have your drawings and any survey information. We give a realistic target at enquiry rather than a guarantee.
