What Is a Build-Over Survey?

A Build-Over Survey examines the proximity and condition of drainage systems beneath a proposed building site. At National Drain Surveys, we determine if construction could affect existing drains or sewers, requiring compliance with local water authority guidelines.

We use advanced CCTV inspection technology, including Pan-Tilt-Zoom (PTZ) cameras, to navigate and assess the underground drainage network thoroughly. Our surveyors check for any encroachments, blockages, or potential weaknesses in pipes made from materials such as clay, uPVC, or cast iron.

In addition to detecting possible interferences with critical services, we check for adherence to British Standards such as BS EN 752, which covers drain and sewer systems outside buildings. The survey includes a detailed report that highlights underground assets, their condition, and specific recommendations for any necessary drainage modifications.

This survey is essential for ensuring your project remains compliant and problem-free.

Ensure your project's success by arranging a Build-Over Survey with us today.

What Types of Build-Over Survey Are Available?

In , we offer several types of Build-Over Surveys to suit varying needs:

  • Standard Build-Over Survey: A general overview of the drainage situation before commencing construction, assessing compliance with local building regulations and identifying any potential issues that may affect planning permissions.

  • CCTV Build-Over Survey: Uses CCTV technology to provide an in-depth assessment of underground systems, capturing detailed video footage to detect blockages, fractures, or root intrusions. Our sophisticated cameras can navigate even the most complex pipe networks to deliver precise diagnostics.

  • Hydrostatic Pressure Testing: Checks the pressure stability of the current drainage system to ensure resilience under new loads. This involves sealing off sections of the system and filling them with water to evaluate their ability to withstand added stress from planned structures.

Our surveys are designed to meet the requirements of architects, builders, and homeowners, ensuring all drainage components are evaluated to industry standards. Contact us to determine which survey type best suits your specific requirements.

When Is a Build-Over Survey Needed?

A Build-Over Survey is necessary when planning construction projects nearby existing drains or sewers. Local water authorities, such as Thames Water or Anglian Water, typically require this survey before granting approval for construction.

The survey involves using CCTV inspection cameras to assess the condition and positioning of the drains and sewers. This helps in identifying any potential issues, such as blockages or structural weaknesses, that could affect your project's integrity.

It is also crucial in preventing damage to underground utilities and ensuring compliance with regulations such as the Building Regulations 2010. These surveys are essential for both residential and commercial properties, including new housing developments and commercial buildings.
