Bridge and Culvert Surveys for Roads, Stormwater and Compliance

MCS Surveyors provide precise culvert and bridge location surveys to support infrastructure design, drainage upgrades and flood management projects across Sydney and regional New South Wales. Whether you are designing a new roadway, upgrading a drainage system or conducting a flood study, our surveyors deliver accurate data on the position, condition and dimensions of culverts, bridges and associated stormwater structures.

Our experienced team works closely with engineers, councils and civil contractors to ensure critical drainage and transport infrastructure is documented in detail. With over 30 years of combined experience in civil and infrastructure surveying, we are trusted by clients for our technical accuracy, fast turnaround and commitment to compliance.

What Are Culvert & Bridge Location Surveys?

Culvert and bridge location surveys involve the detailed mapping of stormwater culverts, road bridges, footbridges, and their associated infrastructure. These structures play a key role in managing stormwater flow, preventing erosion, and maintaining connectivity across waterways and drainage channels.

Our surveys capture:

  • The horizontal and vertical position of culverts and bridges
  • Invert and obvert levels
  • Pipe and channel dimensions
  • Headwalls, wingwalls and pits
  • Flow direction and connectivity to drainage systems
  • Surrounding topography and watercourse features

This information is essential for hydraulic modelling, drainage planning, structural upgrades and infrastructure design.

When Are These Surveys Needed?

Culvert and bridge location surveys are required in a wide range of civil, stormwater and infrastructure projects, including:

  • Road and rail construction
  • Subdivision and urban development
  • Flood risk assessment and mitigation
  • Waterway or channel realignment
  • Stormwater drainage upgrades
  • Asset condition and maintenance audits
  • Environmental impact assessments

Whether you are submitting a development application, preparing design plans or seeking council approval, our surveys provide the clarity and accuracy needed to move your project forward.

Why Accurate Culvert & Bridge Surveys Matter

These structures are often found in flood-prone or drainage-sensitive areas, where even small changes in level or alignment can significantly affect water flow. Inaccurate or incomplete survey data can lead to:

  • Flooding due to under-capacity culverts
  • Design delays or rework
  • Non-compliance with council or water authority standards
  • Safety risks from improper bridge construction
  • Costly drainage failures or erosion damage

MCS Surveyors help you avoid these issues by delivering reliable, high-precision data that forms a trusted foundation for design and compliance.

Our Survey Process

At MCS Surveyors, we tailor each culvert and bridge location survey to your project’s specific scope and regulatory requirements. Our typical process includes:

Initial Consultation

We work with your engineers, planners or project managers to confirm site scope, access and data requirements.

On-Site Survey

Our team uses high-accuracy total stations, GNSS equipment and 3D scanning where required to capture precise location and elevation data.

Data Capture

We document invert levels, bridge soffits, structural features, surrounding drainage, and any obstructions or blockages affecting flow.

Plan Production

Survey data is compiled into a detailed plan or digital model, including all relevant levels, dimensions and alignment details.

Reporting and Delivery

Final plans are provided in the requested formats (PDF, DWG, DXF, etc.) and are suitable for design, approvals or integration into broader drainage models.

Who Needs a Watercourse or Channel Survey?

These surveys are commonly required by:

  • Civil engineers and hydraulic consultants for drainage modelling
  • Property developers and builders preparing DAs or CDCs
  • Councils and government agencies managing stormwater infrastructure

    We work closely with engineers, town planners and environmental professionals to provide the information they need for responsible, efficient design.

  • Environmental consultants conducting impact assessments
  • Infrastructure contractors working on bridges, culverts or channel upgrades

If your development site is within proximity to a watercourse or mapped drainage channel, survey data is likely to be a council requirement during the planning phase.
