Advanced Surveying Equipment & Mapping Technology

It is best to involve a civil engineer early in the planning process. An early evaluation can help identify drainage, utility, access, grading, permitting, and infrastructure issues before significant time and money are committed to a project.

Laugenour and Meikle supports residential, commercial, industrial, institutional, recreational, agricultural, and public works projects. Services can range from an individual site improvement to a large subdivision or infrastructure development.

Yes. Our team can evaluate available property information, existing infrastructure, site constraints, access, drainage, utilities, and regulatory requirements to help you better understand a property’s development potential.

Yes. Laugenour and Meikle offers civil engineering, land surveying, mapping, planning, and entitlement services. Having these services available within one firm can improve communication and coordination throughout the project.

Yes. Our team can prepare the necessary engineering documents, coordinate with reviewing agencies, respond to comments, and assist as the project moves through the approval process.

Yes. Depending on the project, Laugenour and Meikle can assist with bidding questions, plan clarifications, design revisions, field coordination, inspections, and other construction-related engineering needs.

Drone surveying and aerial mapping use specialized unmanned aircraft to capture high-resolution, georeferenced images and site data from above. This information can support topographic surveys, existing-condition mapping, site planning, construction documentation, earthwork analysis and other civil engineering or land-development applications.

Laugenour and Meikle uses RTK aerial mapping drones alongside GPS, robotic and conventional surveying methods. The appropriate combination of technology depends on the property, terrain, accuracy requirements and intended use of the final information.

RTK technology improves the positioning of aerial data, but final accuracy depends on several factors, including the equipment, flight plan, ground control, terrain, vegetation, weather, data processing and required deliverables.

Laugenour and Meikle evaluates each project to determine whether drone mapping, ground-based surveying or a combination of methods is appropriate. Aerial technology does not replace professional surveying judgment or established quality-control procedures.

Depending on the project scope, aerial mapping data may support the development of high-resolution aerial imagery, georeferenced orthomosaic maps, existing-condition maps, topographic information, contours, digital surface models, three-dimensional site representations, earthwork calculations and construction-progress documentation.

Laugenour and Meikle will discuss the required accuracy, intended use and preferred file formats before beginning the survey.

A hydrographic survey measures and maps underwater conditions, including water depths, bottom elevations and cross sections. Bathymetric mapping focuses on documenting the shape and elevation of the underwater surface, similar to how a topographic survey maps terrain on land.

This information can support drainage, water-resource, agricultural, environmental, sediment, dredging and infrastructure projects.

Yes. Depending on site access, water conditions and project requirements, Laugenour and Meikle can collect water-depth and bottom-surface information in ponds, canals, rivers, reservoirs, drainage facilities and other bodies of water.

Our team uses the HydroLite TM2 focused-beam sonar and Seafloor HyDrone survey boat to support bathymetric mapping, hydrographic cross sections and underwater existing-condition documentation.

A remote-controlled hydrographic survey boat is a small unmanned vessel equipped with sonar and positioning technology. Laugenour and Meikle’s Seafloor HyDrone can follow planned survey routes while collecting water-depth measurements without requiring survey personnel to be placed directly on the water.

This technology can be especially helpful in shallow, confined, difficult-to-access or potentially unsafe locations where using a conventional survey boat may be inefficient.

Laugnour and Meikle can help locate and trace detectable underground metallic pipelines, conductive utilities and certain nonmetallic facilities equipped with a usable tracer wire. Once identified, our survey crews can collect the apparent horizontal position of the pipeline and incorporate it into utility maps, topographic surveys, construction staking plans or as-built documentation.

Detectability depends on the pipeline material, tracer-wire condition, access points, depth, interference and surrounding site conditions. Laugnour and Meikle’s services do not replace the required 811 notification process or markings provided by utility owners.

Laugenour and Meikle provides civil engineering, land surveying and mapping services throughout Northern and Central California. Our primary service area includes Woodland, Davis, Sacramento, West Sacramento, Yolo County, Sacramento County, Solano County, Colusa County, Napa Wine Country and the San Francisco Bay Area.

Service availability for drone mapping, hydrographic surveying and pipeline locating depends on the project location, site conditions, required deliverables and applicable access or operational restrictions.
