## Summary

Westminster City Council has completed the award stage for a procurement contract concerning the development of a Web-based Digital Platform designed to streamline the submission and review of whole life carbon assessments within its Town Planning department. This services contract, announced on 26 March 2025, has been awarded to Preoptima Limited. It aims to bolster compliance with the RICS Whole Life Carbon Assessment for the built environment. The platform will be funded in part by Innovate UK and the initial contract will last for three years, with an option for a five-year extension. This project falls under the information systems and technology planning services category and will be implemented in London (UKI32), with a total contract value of £510,000.

This procurement creates significant opportunities for businesses specialising in web-based software development, particularly those that focus on enterprise resource planning and managing environmental impact assessments. Small and medium-sized enterprises (SMEs) with expertise in developing secure, user-friendly digital platforms that handle large datasets and facilitate regulatory compliance will find this tender particularly appealing. The development of an automated review process and integration with Westminster City Council’s planning processes emphasises the technical capabilities needed and the growing market demand for advanced compliance platforms in regulatory sectors. Companies aiming to innovate in environmental and urban planning technology stand to benefit substantially from engaging in such projects.

### Procurement Information

Regulation 32(2)(b) of the PCR enables the award of a public contract by a negotiated procedure without prior publication where the services can only be supplied by a particular economic operator where competition is absent for technical reasons but only in the case where no reasonable alternative or substitute exists and the absence of competition is not the result of an artificial narrowing down of the parameters of the procurement. The service has carried out market due diligence and Market Engagement to assess existing supplier capabilities in relation to the provision of a web-based Whole Life Carbon review platform for local authorities. From the submissions received, officers are satisfied it has been confirmed that no provider other than Preoptima is currently able to provide a fully developed, functional web-based WLC review platform that meets the council's needs. Preoptima holds a registered patent for the Control Model underpinning its platform. Its fully functional and tested generative design model to review building material quantities and carbon emission, allows for element and material level checks to be carried out against a generative control model. This exceeds "document comparison" level reviews. It is to be noted that the council are applying PCR 2015 and not PA 2023 regulations due to the engagement with Prepotima and the publication of a notice under Regulation 40 of PCR 2015 prior to 24/02/25.
