What are 4 points of quality assurance?

Quality assurance helps you inspect goods or services before they reach the customer. In the context of utility mapping and subsurface utility engineering, the four components of quality assurance are:

  • Confirm things are working the way they should – Ensure there are no unidentified subsurface utilities under construction sites.

  • Measure pre-determined processes and ensure you meet compliance requirements – Take precautions to safeguard existing utilities, both known and unknown.

  • Record insights derived from the first two steps – map all utilities and subsurface infrastructure in the target area.

  • Implement changes if an opportunity exists for a smoother process – Foresee how risks to utilities can be mitigated during digging projects

What are some examples of quality assurance?

A few examples of quality assurance include reviewing and establishing  process standards, documentation of processes, auditing different processes, and making project checklists. During any digging project, this involves accurately mapping subsurface infrastructure, both known and unknown, and liaising with different entities involved, all the while maintaining records of communications and planning for risk minimization and mitigation.

What is the role of quality assurance?

The role of a quality assurance professional is to inspect products and services at various pre-planned phases. Quality assurance ensures that services and products meet consistent standards and that there is a reduction in defects and deficiencies. Quality assurance professionals overseeing projects that involve breaking ground can use smart utility maps to identify subsurface infrastructure such as water and gas mains, electrical and telecommunication infrastructure, and sewer pipelines. In addition, AI-enabled utility maps help them to ensure compliance with regulations, and ensure safety of manpower, surrounding communities, and infrastructure.

What role does utility verification play in ensuring safety on construction sites?

Utility verification plays a crucial role in ensuring safety on construction sites. Before commencing any excavation or construction activities, it is essential to verify the presence and location of underground utilities accurately. This verification process helps identify potential hazards and prevent accidental damage to utility lines, which can lead to safety incidents, injuries, and even fatalities.

How is utility verification different from utility locating?

Utility verification, utility locating, and utility mapping are related but distinct processes in the context of construction projects. Utility locating involves the initial identification and marking of underground utilities before construction begins. This process focuses on identifying the approximate location of utilities to prevent accidental damage.
