Topographic Surveys

Topographic surveys are typically a first step in any construction or development project, it may be necessary to perform a topographic land survey to identify various features and elevations of area land.

A topographical survey, also known as a land survey or contours. Topographical land survey measures and identifies the exact location and specifications of natural and human made features within an area of land. The survey is then drawn up into an appropriate and detailed plan it includes human-made features such as boundaries, neighboring buildings, walkways etc. The topographical survey also picks up natural features such as trees, ponds and ground contours.

How Topographic Surveys Are Used

construction and architectural projects
environmental restoration and property improvements
guidance for setting up grading or drainage ditches
when land developed for one purpose is being used for another purpose
establishing and control for accurately defining locations
It can provide the necessary data you will need about the land before making any changes to it.

Road Survey

A highway survey can be used to provide an accurate layout of the road, utilities, drainage, overhead wires, nearby buildings, and other features.

Surveying of Road includes both existing roads and to-be-built road constructions. We have developed a range of road condition measuring devices and employ the same while conducting the surveying. Our team helps in providing high-speed, high-quality condition information on road conditions involving survey. We collect the data, and offer post processing services to ensure the data is integrated with your asset management system.

Road surveying includes:

Boundary Surveys
Route Surveying
Topographical surveying and land surveying
Route Alignment surveying
Fly Levelling
Levelling & Traversing
Reference point surveying
Construction Staking and As-built Surveys
Drainage Feature and Facility Surveys

Contour Survey

A contour survey is a way to easily visually understand the vertical and horizontal shape (the “topography”) of your land. By understanding the land contours, you can easily visualise or map how water will flow across and through the property when it rains, where it will collect, where it might erode the soil and many other important water flow characteristics. From this simple base, you can even develop water flow models, stream maps and determine the best places to create dams and silt traps.

Uses of contours

Contouring in surveying is the determination of elevation of various points on the land and fixing these points of same horizontal positions in the contour map.
Contours provide valuable information about the nature of terrain. This is very important for selection of sites, determination of catchment area of a drainage basin, to find intervisibility between stations etc.

Contour map provides useful information for locating a route at a given gradient such as highway, canal, sewer line etc.

Boundary surveys

A boundary survey is a way to formally define the boundaries of a property. The dimensions of a lot come from deed, subdivision plats, and survey drawings. They show the exact lines of the property. You can choose to have a boundary survey include any improvements made on the land by previous owners.

A boundary survey is an important component of pre-construction due diligence. The boundary survey establishes the perimeter of a property as it relates to a site’s legal description.

The Purpose of Boundary survey are:

Before improvements are made to the property (buildings, fences, excavation, etc.)
Property boundary is in dispute
Boundary location is unknown or unclear
To establish easements and rights of way, Land Title Conflicts etc
When buying, selling, investing in or developing a property
To stop encroachments from adjoining owners

Plot Plans

Plot plans show the lot dimensions, where the builder plans to put the improvements on the lot, the setback lines and easements. Surveys will show if any of these items encroach over and onto neighboring lots or if items from neighboring lots encroach over and onto the subject property. The plot plan is basically an arrangement drawing that shows the equipment and supporting facilities (pipe racks, structures, buildings, roads) that are required for the process facility within a battery limit area, which will be designed for independent operation and shutdown.

Setting Out of Buildings etc.

Setting out is the process of locating points for columns, site boundary level, pile position and other necessary structural parts according to the construction drawing. Errors should be avoided because the whole structure will be build based on the respective setting out

Building Survey usually involves taking accurate measurements of the building and developing complete sets of plans.

The Purpose of Setting Out Survey are:

Boundary
Columns
Pillar Marking
Layout
Route Alignment
Road and Railway
Transmission

Pipeline Survey

A pipeline Survey is defined as the method of assessing the existing condition of sewer collection and water distribution pipelines that run underneath a city. A pipeline survey can estimate the extent of damage and deterioration of a pipeline, and assess any need for repair, replacement or rehabilitation. With the advancements in trenchless technology, it is possible to determine the condition of installed pipelines without having to dig in order to visually inspect and repair a pipeline. Regular pipeline surveys can help prevent failures by highlighting weak spots, cracks, and corrosion in pipelines before they fail.

Pipeline survey surveying includes:

Right of Way Routing
Potential terrain obstacles including streams and road crossings
Existing land use
The client’s existing pipeline and compression facilities
Design and Mapping
Construction Management
Pipeline Inspection Services
Pipeline Integrity Management

Level Works

Levelling is a process of determining the height of one level relative to another. It is used in surveying to establish the elevation of a point relative to a datum, or to establish a point at a given elevation relative to a datum.
