Pre-Construction Drainage Surveys

Before any building work begins, our pre-construction drainage surveys give you a clear picture of existing drainage layouts and conditions. Using advanced CCTV inspection, we help you plan effectively, prevent costly disruptions, and ensure compliance with building regulations from day one.

Pre-Construction Drainage Surveys

What is a Pre-Construction Survey?

Records Existing Drainage Layout

Maps out the current drainage system so designers, architects, and contractors know exactly where pipes run before work begins.

Identifies Drainage Condition

Assesses the integrity of existing drains, highlighting any repairs needed before they’re built over or altered.

Supports Planning & Compliance

Often required by local authorities or building control, especially for extensions, to confirm the location and condition of nearby drainage.

Reduces Risk & Delays

Prevents costly surprises during construction by ensuring drainage conflicts are identified early, keeping your project on schedule.

Pre-Construction Drainage Survey Process

Step 1 - Information Gathering

We begin by collecting information, and when possible, we will request a basic site layout from you.

Step 2 - Surveying

Next the Survey will be carried out on site, defects and drainage locations are recorded

Step 3 - Drainage Layouts

Drainage layouts made in "as-laid" format are produced; these can either be overlaid onto your site layout if provided or onto satellite imagery.

Step 4 - Report Generation

We create a comprehensive report that aligns with the drainage layout, enabling you to efficiently plan your construction phase.

Step 5 - Quotations

If any defects are observed we will also provide you quotations to resolve the issues.

Pre-Construction Drainage Surveys

Before breaking ground, ensure your project starts on the right foot with our comprehensive Pre-Construction Drainage Surveys. Our expert team carries out detailed CCTV inspections to map and assess existing drainage systems, identifying their location, condition, and suitability for integration or alteration. This information is vital for large new-build developments and can also be a planning or building control requirement for smaller extensions, proving where nearby drainage is — or is not — present.

Skipping this crucial step can lead to serious setbacks, including unexpected drainage conflicts, costly mid-project alterations, construction delays, and non-compliance with local authority requirements. By understanding your site’s drainage from the outset, you can plan more effectively, avoid unnecessary disruption, and keep your build on time and on budget.

What is a pre-construction drainage survey?

It’s an inspection carried out before building work begins to map the location and assess the condition of existing drainage systems. This ensures your project plans take into account any drains on or near the site.

They’re essential for large-scale developments and often required for small extensions by local authorities or building control to prove where nearby drainage is — or isn’t — located.

We use advanced CCTV inspection equipment to map the drains and assess their condition. On larger sites, a Jet Vac may be used to clean and clear drains for full access and visibility.

It helps prevent costly mid-project changes, ensures compliance with regulations, and reduces the risk of drainage conflicts that can delay your build.

Yes. You’ll receive a detailed report with drainage maps, condition assessments, and recommendations — suitable for submission to planners, building control, or your project manager.
