Private EM and GPR Utility Locating in Atlanta

GIS exports refer to the process of exporting data or maps from a Geographic Information System (GIS) software to a different format or file type. GIS software allows users to create, edit, analyze, and visualize spatial data, such as maps, satellite imagery, and geospatial datasets.

Exporting GIS data can be done in various formats, depending on the specific requirements and intended use of the exported data. Some common GIS export formats include:

Shapefile (.shp), KML/KMZ, GeoTIFF (.tif), CSV, PDF

GPR and EM Locate CAD overlays refer to the process of overlaying GPR data onto a CAD software or drawing. This allows for the integration of GPR data with existing CAD drawings or models, providing a visual representation of the subsurface features detected by the GPR survey.

By overlaying GPR data onto CAD software, engineers, architects, and other professionals can gain valuable insights into the subsurface conditions and make informed decisions during the design and construction process. It allows for a better understanding of the existing infrastructure and potential conflicts or risks that may arise during construction.

Field Markings are used to show the location of all the utilities located on site.

The condition of the steel reinforcement bars (rebar) is assessed for corrosion, which can weaken the deck's structural integrity.

Expansion joints, bearings, and other connections are inspected to ensure proper functioning and to identify any wear or damage.

Spalling (chipping or flaking) and scaling (loss of the concrete's surface layer) are examined as they can lead to further deterioration.

The frequency of inspections varies depending on factors like the bridge's age, location, and traffic load. Generally, bridges are inspected every 1 to 2 years for routine assessments, with more frequent inspections for older or heavily used bridges.

Bridge deck inspections use visual inspections, non-destructive testing (NDT) methods like ground-penetrating radar and ultrasonic testing, and sometimes destructive testing for material analysis.

Common signs include cracks, spalls, scaling, corrosion stains, exposed rebar, and surface roughness. These signs can indicate various types of deterioration and structural issues.

Corrosion mitigation may involve removing corroded concrete, applying protective coatings, or installing cathodic protection systems to prevent further corrosion of steel reinforcement.

Expansion joints allow the bridge to expand and contract with temperature changes while maintaining structural integrity. They prevent cracking and damage caused by thermal expansion.

Inspections can be scheduled to minimize disruption to traffic. In some cases, lane closures or temporary traffic control measures are implemented to ensure safety during inspections.

If significant issues are detected, engineers will develop a repair or maintenance plan to address them promptly. Depending on the severity, temporary load limits or closures may be necessary for safety.

Regular maintenance, such as sealing cracks, repairing minor damage, and applying protective coatings, can prevent deterioration and significantly extend the lifespan of a bridge deck.

Bridge deck inspections are typically conducted by certified bridge inspectors who have undergone specialized training and have knowledge of structural engineering and materials science.
