The Essential Guide to Build Over Surveys for Architects and Construction Firms
In the world of architecture and construction, every detail matters. A build over survey is a critical yet often overlooked step in ensuring projects run smoothly, comply with regulations, and avoid costly pitfalls. This guide will walk you through everything architects and construction firms need to know about build over surveys, empowering you to tackle this essential process with confidence.
What is a Build Over Survey?
A build over survey is a specialised inspection that determines the position, condition, and accessibility of underground drainage systems when construction is planned above or near them. Conducted via CCTV drainage surveys, this assessment ensures that existing water authority assets, such as public sewers, remain protected and functional during and after construction.
Why Are Build Over Surveys Essential?
Compliance with Water Authorities: In the UK, water authorities require approval before any construction can occur over or near public sewers. A build over survey is often a prerequisite for gaining this approval.
Preventing Structural Issues: Ensuring the sewer’s integrity avoids potential structural weaknesses that could jeopardise both the drainage system and the new construction.
Avoiding Delays and Legal Challenges: Identifying issues early prevents project delays and mitigates risks of disputes with water authorities or property owners.
When Do You Need a Build Over Survey?
New Builds: When a project involves constructing over or within three metres of a public sewer.
Extensions: Adding structures such as conservatories or home extensions near existing drainage systems.
Commercial Developments: Larger projects with complex drainage networks.
How is a Build Over Survey Conducted?
Initial Assessment: Experts identify the location of sewers and inspect site plans.
CCTV Inspection: High-definition cameras assess the internal condition of the drainage system.
Report Submission: A comprehensive WRC approved report is prepared, highlighting findings along with any recommendations.
