Infrastructure & Civil Surveying Services
H&M Surveying partners with engineers, municipalities, and contractors to support the infrastructure that keeps communities moving. From roads and bridges to water systems and utility corridors, we provide topographic surveys, right-of-way plats, construction staking, and GIS data collection to help projects stay on track. Combining time-tested expertise with innovative tools like UAV and GIS, we deliver the accuracy you need for even the most complex civil engineering challenges.
Greenville Dig
H&M Surveying provided critical surveying support for Renewable Water Resources’ (ReWa) transformative wastewater tunnel project beneath Greenville, South Carolina. Spanning 1.3 miles from Cleveland Park to Hudson Street near downtown, this 10-foot diameter tunnel was designed to connect and modernize the entire city’s wastewater network, enhancing capacity and resilience for decades to come.
Our team performed precise construction staking above ground to guide the alignment of the tunnel and support critical surface infrastructure throughout the project. Leveraging robotic total stations and survey-grade GPS, we established and maintained a robust control network to ensure accuracy across the tunnel’s considerable length and depth.
Upon completion, H&M Surveying conducted a full as-built survey of the tunnel’s 7-foot fiberglass pipe system. The pipe began approximately 40 feet below the surface at Cleveland Park and extended to a depth of nearly 100 feet at Hudson Street. This work verified the precise location, alignment, and grade of the installed infrastructure, ensuring it met engineering tolerances for long-term reliability.
The project’s urban setting and substantial depth presented significant challenges, including navigating congested areas, maintaining accuracy over extended distances, and working near environmentally sensitive landmarks such as the Reedy River. H&M Surveying’s expertise, combined with advanced technology and seamless coordination with engineers and contractors, helped deliver the project on time and to exacting standards.
Our involvement in this high-profile initiative demonstrates H&M Surveying’s ability to support large-scale utility and infrastructure projects with exceptional precision and professionalism.
Riverbend Subdivision
H&M Surveying was engaged to support a unique stormwater management assessment for a residential subdivision in Bluffton, South Carolina. Situated near mean sea level (MSL), the site presented an uncommon challenge: the interconnected system of ten stormwater ponds tied into each other and discharged to a single outlet where surface elevations rose and fell with the tide.
Our team performed detailed bathymetric mapping of the pond system to determine the true capacity of the subdivision’s stormwater infrastructure. Using advanced survey techniques, we accurately mapped the pond floors beneath approximately 0.43 feet of organic material to reach the underlying sediment surface. This work provided the subdivision with a clear and actionable understanding of its remaining stormwater storage capacity and informed future maintenance planning.
This project highlights H&M Surveying’s ability to deliver precise, reliable data in dynamic and environmentally sensitive coastal conditions.
Mill Village Wastewater Mapping
H&M Surveying partnered with the Metropolitan Sewer District to support a large-scale wastewater mapping initiative across several historic mill villages in Greenville County, South Carolina. The project focused on the Judson Mill, Dunean Mill, Mills Mill, and Union Bleachery Mill communities—areas with aging infrastructure and intricate utility networks.
Our team mapped over 300,000 linear feet of sewer lines and documented thousands of associated structures, including manholes, cleanouts, and lateral connections. Using a combination of robotic total stations and survey-grade GPS, we established precise control and captured highly accurate spatial data throughout these dense urban environments. The resulting dataset provided the utility with the critical information needed to modernize and maintain vital wastewater infrastructure serving these historic neighborhoods.
This project underscores H&M Surveying’s ability to tackle large-scale utility mapping efforts with advanced technology and deliver reliable data for planning and asset management in legacy systems.
