Surveying + Engineering. One Coordinated Team.

Successful engineering begins with accurate information about the land.

By integrating surveying with Blackline’s civil engineering, land development, platting, infrastructure, GIS, and construction capabilities, our clients benefit from better coordination from the earliest stages of a project through final construction.

Our survey professionals work closely with Blackline’s engineers, planners, project managers, and field teams to identify issues early, improve communication, and help keep projects moving.

From S&V Surveying to Blackline Engineering

More Than 30 Years of Houston-Area Surveying Experience. Now Part of a Broader Team.

Blackline Engineering continues the strong tradition of S&V Surveying, combining established surveying expertise with the resources and capabilities of a multidisciplinary engineering organization.

The combination of S&V Surveying and Blackline Engineering brings surveying, civil engineering, land planning, GIS, infrastructure design, and construction support together within one organization.

The result is a more integrated approach to project delivery—connecting the professionals gathering critical information in the field with the engineers, planners, and project teams using that information to design and deliver successful projects.

For existing S&V clients, the commitment remains the same: responsive service, accurate work, and practical solutions. Those capabilities are now supported by the broader resources and multidisciplinary expertise of Blackline Engineering.
