Bachy and Kilnbridge launch urban delivery venture

Bachy Soletanche and Kilnbridge have launched UrbanCore, a specialist ground-to-frame venture aimed at complex city construction projects.

The new offer brings together demolition, dismantling, material reuse, foundations, basements, reinforced concrete, and steel frames under an integrated delivery model. The companies are targeting commercial developments and basement-led schemes in dense urban locations, where the split between groundworks, substructure, and structural packages can create delay, cost uncertainty, and blurred accountability.

UrbanCore is already being used on live projects, including complex substructure and structural works at One North Quay in Canary Wharf. The venture is designed to bring engineering teams together earlier in the process, giving clients a single route through the technically demanding stages between site clearance and structural frame completion.

Dense urban construction often exposes weaknesses in traditional package boundaries. Demolition decisions can affect basement sequencing, retained structures, reuse opportunities, temporary works, piling methodology, crane strategy, frame design, and logistics. When those elements sit in separate contracts, a change in one area can quickly become a redesign, access constraint, claim, or programme delay elsewhere.

By combining two specialist contractors, UrbanCore is intended to reduce those interface risks. Bachy Soletanche brings deep foundations, geotechnical, and substructure capability, while Kilnbridge adds demolition, concrete, structural, and complex construction delivery experience. The offer is not simply a wider list of services; it is an attempt to align design, planning, temporary works, and construction sequencing before the site reaches its most expensive stages.

Clients bringing forward central urban schemes are increasingly trying to unlock difficult sites without exposing projects to avoidable coordination failures. British Land’s West One scheme above Bond Street Underground Station, where McLaren is delivering a £99m commercial retrofit, sits in a similar family of construction challenge: live surroundings, structural intervention, constrained access, existing assets, and high-value end use.

UrbanCore is aimed at the earlier, heavier part of that construction sequence. Foundations, basements, demolition, retained structures, and frames can define the risk profile of an entire project. If those packages are poorly aligned, later fit-out and handover activity inherits the delay. If they are planned together, the site can move from clearance to frame with fewer commercial gaps between disciplines.

Material reuse adds another layer to the proposition. Existing structures in dense urban locations can either become waste or form part of a more deliberate resource strategy. That decision affects demolition method, testing, certification, storage, design coordination, and programme. Reuse is often difficult to retrofit into a project once demolition planning is already fixed, but it can be more practical when considered alongside temporary works, logistics, and structural design at the front end.

Basement-led schemes remain among the most risk-sensitive areas of commercial construction. Temporary works, party wall issues, groundwater, adjacent assets, logistics, noise, dust, and structural sequencing all require close control. Delays below ground hold back the entire project, while errors in substructure or temporary works can be expensive to correct once the frame begins.

UrbanCore’s commercial test will be whether clients place enough value on integrated procurement to move away from traditional package splits. On simpler schemes, buyers may still prefer separate tenders to preserve competitive tension. On constrained sites, however, accountability and early engineering integration are becoming harder to separate from cost and programme certainty.
