## Summary

Trinity House, a central government public authority, is initiating a planning phase for a procurement process titled "CM17 - Geotechnical and Civil Engineering." This tender relates to services in the geotechnical and civil engineering sectors, specifically aimed at supporting the maintenance of aids to navigation, including depots, vessels, lighthouses, buoys, and beacons across the United Kingdom. Located in Tower Hill, London, this procurement process invites interested suppliers to engage by expressing their interest via email before the deadline on 31st December 2025. The contract is substantial, with a gross value of £1,200,000 and spans a potential period from 2026 to 2030, with the initial contract period set between 2026 and 2028. This opportunity falls under the "services" category and is a significant open tender above the threshold.

This tender presents substantial opportunities for growth for businesses in geotechnical and civil engineering fields, offering the chance to work on prestigious projects linked to national navigation aids. Firms that can offer expertise in architectural and building-surveying services, quantity surveying for civil engineering works, and marine survey services would be particularly well-suited to compete. Companies with capabilities in sewer survey and sewage treatment consultancy may also find this tender aligned with their services. Engaging in this project not only positions businesses for growth through high-value contracts but also enhances their reputation by partnering with a renowned governmental entity like Trinity House.
