In this marketing case‑study video, William Doyle MRICS explains how Tier‑1 contractor Costain tackled the challenge of maintaining consistent, auditable subcontractor reporting across large infrastructure programmes such as the A12 upgrade and the Gatwick Station redevelopment. Costain partnered with the Gather platform to standardise data capture under NEC requirements, configuring a single workflow that all subcontractor packages followed from day one. The solution unified hundreds of records into a real‑time, auditable picture, delivering daily consistent reporting and cutting reporting time by almost 40%. The deployment was rapid and easy for users, reinforcing Costain’s DNA of consistency and enabling leadership to act swiftly. The video ends with a call‑to‑action inviting viewers to book a demo of Gather for their own supply chains.

Tier 1 contractors like Costain don't leave consistency to chance. It's part of their DNA, and it's how they deliver some of the UK's most complex infrastructure programmes. On the A12 upgrade and the Gatwick Station redevelopment, it meant every subcontractor working to the same playbook from day one. Gather was a huge part of that, turning hundreds of records into one clear, consistent picture that leadership could act on. There were multiple subcontractor packages, each with their own teams, scopes, and reporting style. Every single record had to match the same high bar. It had to be auditable, consistent, and accurate. Costain chose Gather to make consistency a given. Working with Costain's PMO and commercial teams, we mapped out exactly what needed capturing under NEC, right down to the scope wording for the subcontractors. Then we configured Gather so that every package would follow the same workflow, from access process, activities, events, and resources. They were all captured in real time, not days later. From day dot, the impact was obvious. There was consistent daily reporting from every subcontractor, and reporting time was cut by nearly 40%. Quick to deploy, simple to adopt, and part of how Costain delivers today. Big projects don't slow down for messy records, and neither should you. Gather gives you the consistency, clarity, and confidence to keep things moving. Book your demo now to see it in action across your supply chain.
