Build Over Surveys in Dundee

Thinking about adding an extension, a new garage, or a conservatory to your house? It’s an exciting project, but before the foundations go in, there’s a critical step you can't afford to miss: checking what lies beneath the ground. If your build is planned near or over a public sewer, you will need a formal build-over agreement with Scottish Water. The first step in securing that agreement is a professional CCTV Build-Over Survey from Go-Flow.
We help homeowners, builders, and architects across Scotland get this vital surveying work done right the first time, preventing costly delays and giving you complete peace of mind.

A build-over survey is a detailed health check of a drainage pipe using the latest CCTV camera technology. It’s not just one survey, but a two-part process designed to protect both you and the public sewer network.
First, we carry out a pre-build survey. Our team feeds a high-definition camera into the sewer pipe to record its exact condition before any construction work begins. We document every joint, crack, and connection. This report and footage are submitted to Scottish Water as part of your application.
Second, once your building work is finished, we return to conduct a post-build survey. This follow-up inspection proves that your construction work hasn't caused any damage, like cracks or collapses, to the pipework. This final report completes your agreement and protects you from any future liability for pre-existing faults.

Navigating the rules for building over or near sewers can feel complicated. Go-Flow makes it straightforward. We have extensive experience working with homeowners and developers across Dundee, Fife, Angus, and Perthshire, providing the precise reports Scottish Water needs to see.
Our state-of-the-art surveying equipment provides crystal-clear footage, and our reports are incredibly detailed, covering pipe diameters, materials, and mapping the sewer's path. We don't just give you a video; we give you a complete, professional package that helps your planning application move forward smoothly. And if the survey does uncover a problem, our expert drainage repair teams can fix it, often using 'no-dig' technology to avoid major disruption.

If your new foundation or structure is planned within three metres of a public sewer line, the answer is almost certainly yes. Scottish Water needs to protect these vital assets, and a survey is their way of getting a baseline of the pipe's condition. Your architect or builder should flag this up, but it’s always best to check. We can provide the expert surveying required for your peace of mind and formal approval.

You receive a complete evidence pack to support your application. This includes the full, high-definition video recording of the survey, a detailed written report from our qualified technicians, a schematic drawing of the drain layout, and all the essential dimensional information, including pipe material, diameters, and lengths. We document every important detail.

Discovering a pre-existing issue like a crack or root damage can be worrying, but with Go-Flow, you're in safe hands. We’re not just a surveying company; we are drainage repair experts. We will provide a clear explanation of the problem and a no-obligation quote for fixing it. We specialise in modern, no-dig repair services like patch lining, which can often solve the issue without the cost and mess of excavation.

While a general plumber can unblock a sink, build-over surveying requires specialised skills and equipment. We use dedicated CCTV surveying crawlers and reporting software designed to produce reports that meet the specific standards of water authorities. Our experience in this area means we know exactly what information and formatting are needed for a successful application, saving you time and potential rejection.
