Summary of the contracting process

Westminster City Council procured specialist geotechnical and geo-environmental survey services for Lilestone Street as part of the Lisson Grove Programme in Westminster, London. The work covers ground investigation to establish ground conditions, groundwater levels and related constraints. Its findings will support a Basement Impact Assessment for a future planning application, structural design development, construction risk management and cost certainty. The requirement is for an experienced geotechnical consultant capable of carrying out the investigations and producing the evidence needed for planning and scheme design. The service falls within geotechnical engineering services (CPV 71332000) and is suitable for small and medium-sized enterprises and voluntary, community or social enterprises.

The procurement is complete and the contract was awarded to Lucion Delta Simons Ltd on 24 August 2026. It used a below-threshold open competition, with electronic submission allowed. The original estimated value was £140,000 excluding VAT, or £168,000 including VAT; the awarded value is £172,180.44 including VAT. The awarded contract period runs from 25 August 2026 to 1 December 2026. One lot was used. Qualification was assessed pass or fail against minimum standards including insurance, policies, exclusions and relevant experience. The Most Advantageous Tender was selected using quality at 50% and price at 50%, with responsible procurement accounting for at least 10% of the overall score. Four bids were received and three reached the final stage.

This award shows that Westminster City Council buys focused geotechnical consultancy to support major urban regeneration, planning approval and construction decisions. A credible competitor for a future requirement would need specialist capability in ground investigation and geo-environmental assessment, including determining ground conditions, groundwater levels and development constraints. It would also need to translate survey findings into evidence suitable for a Basement Impact Assessment, structural design development, construction risk management and cost planning. Relevant experience, appropriate insurance, supporting policies and a clean eligibility record are essential entry requirements. The evaluation demonstrates that technical quality matters as much as price, while responsible procurement forms a defined part of the quality assessment. The successful supplier was an SME.
