## Summary

The City of London Corporation commissioned development of Stage 4+ design information for waterproofing works, incorporating an alternative waterproofing product. The work is intended to enable construction works to take place in spring 2027, with the waterproofing works planned for that season. This is a construction-related design and waterproofing requirement, rather than a general building maintenance contract. The buying organisation is The Mayor and Commonalty and Citizens of the City of London. The procurement data identifies the buyer’s City of London address, but does not identify a separate project delivery location.

The procurement is complete: Maylim Limited was selected and the contract was signed on 16 October 2026. The contract runs from 1 November 2026 to 30 April 2027, with a gross value of £79,200. It was awarded through a direct, below-threshold process without competition. The requirement was handled as one lot. The stated purpose of developing the Stage 4+ information and adopting an alternative waterproofing product was to enable construction works in spring 2027. No award evaluation criteria are recorded in the published process data.

This award demonstrates demand from the City of London Corporation for specialist waterproofing-related construction input, including development of Stage 4+ design information and assessment or incorporation of an alternative waterproofing product. A credible competitor for a future requirement of this kind would need to combine design coordination at an advanced project stage with practical knowledge of waterproofing systems and the ability to support subsequent construction works. The work was awarded directly without competition, so the selection does not reveal tested competitive criteria or a published supplier capability threshold. Maylim Limited, a large supplier, was selected for this requirement; the process provides evidence that the buyer has used a substantial construction supplier for this package. The requirement is a focused, single-lot package rather than a multi-lot programme.
