## Summary

Cyngor Gwynedd has awarded a contract for an Integrated Sustainability Appraisal and an accompanying Habitats Regulation Assessment to AECOM Ltd. This contract, part of the services industry, is essential for the preparation of a new Local Development Plan (2024-2039) and is valued at £300,000 gross. Based in Caernarfon, UKL12 region, the buyer had an open procedure procurement method. The tender process initiated as an open call for bid submissions culminated in awarding the contract, which is scheduled to start on 21st January 2026, with a completion date of 20th January 2029, with potential extensions. This award follows the tender process where bids were submitted by 20th November 2025, and the award was announced on 19th December 2025.

This awarded procurement offers substantial growth opportunities for businesses specialising in architectural, construction, engineering, and consultancy services. Large firms capable of delivering complex regulatory assessments and sustainability appraisals are well-suited to compete in such procurements. The long-term nature of the contract and possibility of extension up to 2031 suggests stability and sustained engagement for winning bidders. Companies with a strong presence in the UK, particularly those familiar with Welsh regulations and those capable of provider compliance, stand to benefit from actively seeking tenders in similar local authority projects.
