Surveying and Infrastructure Solutions
We provide a variety of surveying services, including wetland delineation, boundary, as-built, tree and topographic surveys, staking of roadway and drainage projects, and providing finished floor elevation certificates for real estate closings. We have been contracted by engineering, architectural and residential design firms to provide surveying services for the development of both residential and commercial properties. Our client list comprises numerous Federal & State Agencies, major and independent Oil & Gas Companies, pipeline companies, and other industrial and private entities.
The Surveying/mapping services offered by us includes,
- Topographic Surveying
- Cadastral Surveying
- Route Survey
- Utility Surveys
- Urban Planning/Property Survey
- DGPS Control Survey
- Engineering Surveys
Topographic Surveys Topographic Survey: a survey that measures the elevation of points on a particular piece of land, and presents them as contour lines on a plot. The purpose of a TOPOGRAPHIC SURVEY is to gather survey data using Total Stations, Auto levels, GPS etc., about the natural and man-made features of the land, as well as its elevations. From this information a three- dimension al map may be prepared. You may prepare the topographic map in the office after collecting the field data or prepare it right away in the field b y plane table. The work usually consists of the following
- Establishing horizontal and vertical control that will serve as the framework of the survey.
- Determining enough horizontal location and elevation of ground points to provide enough data for plotting when the map is prepared.
- Locating natural and man –made features that will be required by the purpose of the survey.
- Computing distances, angles and elevations.
- Drawing the topographic map Topographic surveys are commonly identified with horizontal and/or vertical control of third- and lower-order accuracies.
CADASTRAL SURVEYS are conducted to establish the exact location, boundaries, or subdivision of a tract of land in any specified area. This type of survey requires professional registration in all states. Presently, land surveys generally consist of the following chores:
- Establishing markers or monuments to define and thereby preserve the boundaries of land belonging to a private concern, a corporation, or the government.
- Relocating markers or monuments legally established by original surveys.
- This requires examining previous survey records and retracing what was done. When some markers or monuments are missing, they are re -established following recognized procedures, using whatever information is available.
- Rerunning old land survey lines to determine their lengths and directions. As a result of the high cost of land, old lines are premeasured to get more precise measurements.
- Subdividing landed estates into parcels of predetermined sizes and shapes.
- Calculating areas, distances, and directions and preparing the land map to portray the survey data so that it can be used as a permanent record.
The term route survey refers to surveys necessary for the location and construction of lines of transportation or communication that continue across country for some distance, such as highways, railroads, open-conduit systems, pipelines, and power/telecom lines. Generally, the preliminary survey for this work takes the form of a topographic survey. In the final stage, the work may consist of the following:
- Locating the center line, usually marked by stakes at required interval called Stations.
- Determining elevations along and across the center line for plotting profile and cross sections.
- Plotting the profile and cross sections and fixing the grades.
- Computing the volumes of earthwork and pre paring a mass diagram.
- Staking out the extremities for cuts and fills.
- Determining drainage areas to be used in the design of ditches and culverts.
- Laying out structures, such as bridges and culverts 8. Locating right-of-way boundaries, as well as staking out fence lines, if necessary.
Utility agencies need extensive data collection related to their assets and consumers, for efficient distribution management and service delivery. We undertake large scale measurement and contact surveys to create comprehensive geo spatial databases for consumer indexing and asset management. Realizing the critical need of meeting cost, speed and accuracy requirements simultaneously, we have designed innovative solutions, employing a judicious blend of technologies.
All types of mapping require establishment of an accurate control framework on the ground. We establish ground control employing differential GPS and/or total stations. Such control surveys are conducted by us for the following requirements.
- Creation of geodetic framework
- Photogram metric mapping
- Field contouring and topography
- Site surveys for real estate and housing developers
- Route plans and profiles for power line and pipe line Corridors
- Engineering surveys
- Property and cadastral surveys
- Monument of archaeological importance
- Setting-out / relaying on the ground for all types of construction work and as-built surveys.
- On-the-ground alignment, cross-section & L–section generation and demarcation of physical infrastructure and utility corridors.
The Infrastructure design team consist of road engineers, structural engineers, costing engineer etc. having hand on experience to handle detail project report for fixing of road alignment , design and structure for Ring Road design.
