Manhole Scanning

Mapping underground infrastructure with unmatched clarity.

At Metro Consulting Associates (MCA), our asset management and manhole scanning solutions surpass traditional inspection methods, enabling utilities and municipalities to collect and organize subsurface infrastructure data for more informed, smarter decisions.

Using advanced remote-sensing technology, we visualize and then digitize conditions within stormwater, sanitary, and sewer system infrastructure, including the connections between underground infrastructure elements.

The result is data-rich snapshots with deep insights, robust analysis, and specifications to industry standards. Eliminating confined-space entry while minimizing surface impact, our team expertly scans manholes, reducing project time and exposure within the right of way.

Once collected, these digital records become a historical archive within the client’s Geographic Information System (GIS), supporting long-term planning, maintenance prioritization, and lifecycle management of critical community assets.

Featured Projects

Detroit Water and Sewer Manhole Scanning

Metro Consulting Associates (MCA) is working on a 3-year, 2,500-manhole scanning project that requires the inspection, rehabilitation, and replacement of sanitary sewers within the City of Detroit. Our scope of work includes various aspects of sewer system maintenance and improvement, including sewer inspections, sewer cleaning and rehabilitation, manhole inspections and GPS location, and sewer repairs. Utilizing SewerAi’s Pioneer Platform for Manhole Assessment Certification Program (MACP) Level 2 Assessment, MCA’s MACP-certified team members are providing consistently high-quality insights into the manhole infrastructure’s conditions.

Wastewater Manhole Scanning and Asset Management

Working with our sister company, Corby Energy Services, the field teams performed sewer pipe assessments per Pipeline Assessment Certification Program (PACP) standards and manhole inspections per Manhole Assessment and Certification Program (MACP) standards within the City’s system.

Gas Distribution Pipeline Replacement Mapping

Metro Consulting Associates (MCA) collected and analyzed field data on 795 of the City of Royal Oak’s catch basins, storm manholes, sanitary manholes, and tops of water gate wells over the course of 8 weeks for the Client’s gas distribution line replacement. Depending on the difficulty of the structure’s location, our field team used traditional survey methods and manhole scanning technology to gather information about each structure, such as elevation, inverted depths, and inverted elevations, as well as the pipe’s diameter, material, and direction. After collecting the field data, our GIS team analyzed it and performed quality assurance and quality control procedures. Additionally, the team created easily identifiable visuals for the client, including point cloud images and pictures. Our Land Survey team processed the analyzed data and prepared the deliverables to submit per the Client's request, enabling them to accurately plan for and map their pipeline replacement project.
