Surveys

CS551 and CD535-compliant drainage surveys, delivered to the most exacting standards in the industry.

We deliver CS551 and CD535-compliant drainage surveys to the most exacting standards in the industry.

Whether you need to understand what’s under the ground before design begins, or capture a complete as-built record once construction is finished, we deliver the full picture, accurately and on time. And because we’re not a large organisation weighed down by inter-departmental process, we can move quickly.

Where surveys identify defects or drainage failures, we can move directly into fixing them. The survey doesn’t just tell you what’s wrong, it’s the start of putting it right.

Why DDC?

As a fully accredited Principal Contractor, we can coordinate and self-deliver every aspect including roadspace booking, traffic management, vegetation clearance, GPR, topographic surveys and confined space entry. Alternatively, we can integrate seamlessly into a Tier 1 delivery team, so when we arrive on site, there’s nothing standing between us and the survey.

The truth is in the data. Our diligence in the field, and the rigour we apply to processing and quality assurance, means we have absolute confidence in what we deliver, and our clients can too.
