The Brief & Challenge
For QSs, drainage subcontractors can either protect margin or create late-stage commercial disputes. The risk is poor financial management: unclear claims, conflict-driven behaviour, and avoidable surprises that damage relationships and budgets. Steven needed a well-established drainage subcontractor who did the job properly and managed the commercial side cleanly. The desired state was financial clarity and professional conduct: fair engagement, accurate QS support, and leadership that comes to the table when something isn’t going to plan—without drama or posturing.
What we did
We supported multiple building sites as a drainage subcontractor, combining consistent delivery with commercially fair behaviour and accurate QS management to avoid disputes.
- Delivered drainage subcontracting across many building sites with repeatable execution.
- Managed the work properly as a well-established operator, reducing delivery risk.
- Provided accurate QS support to prevent cost issues and late-stage disputes.
- Maintained a fair, professional approach when site conditions changed.
- Came to the table to resolve issues collaboratively rather than escalating conflict.
- Stayed commercially competitive while keeping standards and behaviour consistent.
"His QS does her job right, which helps avoid the financial issues you often see when things aren’t managed well." — Steven Lovelock, Quantity Surveyor, Calders Stewart
