Utility scanning before construction enhances safety by identifying underground utilities like gas, water, and electricity lines. Knowing their precise location prevents accidental damage, reducing risks of hazardous leaks and electrical shocks, ensuring a safer environment for workers and the public.
Conducting a utility survey leads to better cost efficiency and planning. Accurately locating utilities helps avoid unexpected strikes, reducing costly repairs and delays. This foresight allows for effective budgeting and scheduling, keeping the project on track and within budget.
Utility scanning ensures compliance with regulations requiring the identification of underground utilities before construction. This avoids legal penalties and promotes responsible practices. It also protects the environment from potential contamination and preserves natural resources by preventing utility damage.
Our service offers precision surveys compliant with PAS 128 standards, including non-GPR options. Benefit from the expertise of our experienced technicians who document buried utilities such as drainage, water, gas, BT, and electrical services. We utilise advanced Leica GPS technology for accurate recording to national grid coordinates, ensuring precise and reliable data.

PAS 128 is the Publicly Available Specification for underground utility detection, verification, and location in the UK. It sets the standard for the accuracy and reliability of utility surveys, ensuring that data collected is consistent and dependable.
PAS 128 provides a uniform framework for utility surveys, ensuring that all surveys meet a high standard of quality. This consistency is crucial for comparing data across different projects and for ensuring reliable results.
By adhering to PAS 128, surveyors can more accurately locate and identify underground utilities, reducing the risk of utility strikes during construction. This enhances safety for workers and the public, and prevents costly damages and delays.
Accurate utility data is vital for effective project planning and design. PAS 128 ensures that the information gathered is precise, helping project managers make informed decisions, avoid unexpected issues, and optimise resource allocation.
Following PAS 128 demonstrates a commitment to industry best practices and regulatory compliance. This can be important for securing project approvals and maintaining professional standards in construction and engineering projects.
