In this promotional case‑study, William Doyle MRICS explains how Tier 1 contractor Costain achieved consistent, auditable records across hundreds of subcontractors on two major UK infrastructure programmes – the A12 upgrade and the Gatwick Station redevelopment. Costain partnered with the Gather platform, working with its PMO and commercial teams to map the required NEC data, configure a single workflow covering access, activities, events and resources, and capture all information in real time. The result was uniform daily reporting from every subcontractor and a near‑40 % reduction in reporting time. The video emphasizes that such consistency is built into Costain’s DNA, positions Gather as the enabler of that consistency, and ends with a call‑to‑action to book a demo.

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.
