Fastest Turnaround Times In The Surveying Industry!
Locate buried services before you dig to avoid damage, delays and safety risks.
MCS Surveyors provide underground asset management surveys across Sydney to help you locate and map critical subsurface infrastructure before work begins. Our surveys identify underground utilities such as water, gas, electricity, and communications lines—reducing the risk of service strikes, unexpected delays, and costly damage. Whether you're planning a construction project, excavation, or utility upgrade, our accurate data supports safer decisions and ensures compliance with local development requirements.

Accurate knowledge of what lies beneath the surface is essential for avoiding service strikes, ensuring worker safety, and meeting project timelines. Underground utilities—such as water mains, gas lines, electrical conduits, telecommunications cables, and stormwater systems—must be properly identified before any excavation or construction begins. At MCS Surveyors, we combine proven surveying techniques with advanced detection technologies, including ground penetrating radar (GPR), electromagnetic locators, and non-destructive methods. This allows us to deliver precise, up-to-date utility maps with minimal site disruption, helping project teams make informed decisions from day one.
We offer a range of underground utility surveys tailored to your project's needs:
These services support design planning, reduce construction risk, and help ensure site safety and compliance with Sydney’s development guidelines.
In complex urban environments, underground pits, conduits, and manholes play a crucial role in housing and connecting critical utility services. MCS Surveyors provide specialised conduit and pit location surveys to help construction teams, engineers, and service providers accurately identify and map these subsurface assets. Using a combination of surface observation, electromagnetic locating, and GPR, we detect the location and extents of telecommunications pits, electrical conduits, and other access structures—ensuring that key service infrastructure is fully accounted for before excavation begins.
By pinpointing conduit and pit locations early, we help you reduce the risk of accidental damage, improve service coordination, and streamline installation or upgrade works. This data is delivered alongside other underground utility findings as part of a complete and practical underground asset survey.
Accurate pipe and cable locating is a critical part of underground asset management. At MCS Surveyors, we use advanced electromagnetic detection tools to identify the position and depth of conductive utilities such as electrical cables, water pipes, and communication lines. Our team interprets this data with precision, delivering clear, georeferenced maps that help your crew dig with confidence. Whether you're planning minor excavation or major infrastructure works, our pipe and cable locating services help you avoid costly damage, ensure worker safety, and comply with regulatory requirements.
Our process adheres to non-destructive locating methods and can be combined with GPR for a more complete picture of both metallic and non-metallic assets. All findings are clearly documented and integrated into our underground utility reports, forming part of a comprehensive asset management strategy.
At MCS Surveyors, we maintain strict standards in underground utility detection to ensure every survey is reliable, detailed, and fit for purpose. Our underground asset surveys are conducted in line with the Australian Standard AS5488, delivering Quality Levels A through D depending on your project's requirements. Whether you're in the early planning stages or finalising construction designs, we provide the right level of data accuracy to support safe excavation, risk reduction, and compliance.
Our experienced team collaborates closely with engineers, designers, builders, and service authorities to ensure all known and detected underground services are clearly identified and mapped. By addressing asset locations early, we help you avoid unexpected conflicts, reduce rework, and protect infrastructure throughout every stage of construction.
At MCS Surveyors, we classify underground asset data using the AS5488 Standard, which defines four Quality Levels to indicate the accuracy and reliability of utility information. Each level supports different stages of a project and carries a corresponding level of confidence:
We tailor each survey to match your site conditions, project phase, and level of required certainty—ensuring your team can make confident, well-informed decisions before groundworks begin.
Find clear answers to common questions about identifying and mapping underground services before starting any construction or excavation work.
Underground asset management surveying involves locating, mapping, and documenting buried infrastructure such as water pipes, gas lines, electrical conduits, and telecommunications cables. These surveys help prevent service strikes, support safe excavation, and assist with planning and design.
Yes—if your project involves any form of excavation or ground disturbance, an underground utility survey is essential. It identifies the location of existing services, helping you avoid costly delays, damage, and safety hazards.
We can locate and map a wide range of subsurface utilities, including water mains, sewer lines, gas pipes, stormwater infrastructure, electrical cables, telecommunications, and fibre-optic lines. Our surveys also include pit and conduit locations, overland flow paths, and service connections.
We use a combination of Ground Penetrating Radar (GPR), electromagnetic locating equipment, and non-destructive excavation methods (such as potholing or vacuum excavation) where required. This ensures accurate and safe detection without damaging existing infrastructure.
Dial Before You Dig (DBYD) provides records of underground assets based on utility plans, which may be outdated or incomplete. A professional utility survey physically detects and verifies service locations on site, delivering far greater accuracy for construction or design.
Our surveys can be delivered to industry-recognised AS5488 Quality Levels A to D, depending on the level of accuracy required. Quality Level A involves physical exposure and is the most precise, while Level D is based on existing records.
MCS Surveyors offers the fastest turnaround times in the industry. Most underground utility surveys are completed and delivered within a few business days, depending on site size and complexity.
We provide survey data in PDF, DWG/CAD, and other formats compatible with engineering, design, and project management software. If your team needs TIN or 3D outputs, we can accommodate those as well.
Whether you’re working on a residential subdivision, commercial project, or infrastructure upgrade, our underground asset management surveys give you the clarity and confidence you need.
