Award Notice
Summary of the contracting process

Bristol City Council procured essential highways civil engineering design support for the A4 Portway Strategic Corridor in England. The appointed design resource is intended to rectify issues in an earlier design revision that made the existing drawings unbuildable, then reissue corrected designs to the works contractor. This is a professional engineering service covering design development and design remediation, classified under architectural, construction, engineering and inspection services. The requirement was bought by Bristol City Council as the buyer and forms part of delivery of the A4 Portway corridor. The procurement was arranged as a call-off under the Consultancy & Professional Services Agreement (AEC3).

The procurement is complete and was awarded through a direct award. The response deadline was 2 July 2026 at 12:00. Bristol City Council awarded the contract to Constellia Public Limited on 28 July 2026 for £421,583.64 including the stated currency, GBP. The contract period runs from 29 July 2026 to 31 August 2026. The award is active. The procurement was conducted as a services contract for highways civil engineering design support, with the direct-award route used through the AEC3 Consultancy & Professional Services Agreement. The published outcome records one selected supplier and one contract period; the contract value is the same as the procurement's stated value.

This award demonstrates demand from Bristol City Council for specialist highways and civil engineering design resource supporting a strategic road corridor. A credible future competitor would need to diagnose and correct design defects, produce drawings that are buildable, and reissue coordinated design information for use by a construction contractor. Relevant capability includes highways infrastructure design, design review, constructability assessment, technical drawing production and the management of revisions through to contractor issue. Experience of strategic corridor or major highway schemes would strengthen a supplier's position, as would the ability to provide suitably qualified engineers at short notice. Suppliers should also understand how to deliver professional services through public-sector consultancy agreements such as AEC3, including the requirements of a direct call-off.
