A construction survey is a process of assessing and plotting the physical characteristics of any construction site and all of its surroundings for collecting data required for designing, planning and constructing buildings, infrastructures and other such projects.  Construction survey is done by a certified land surveyor who makes use of special equipment like GPA, laser cameras, and total stations for measuring and recording the location and elevations of several features on the site of construction, which also includes the natural and man-made features like the land contours, existing buildings, utilities and several other site features.

Construction survey assists in making sure that all projects are developed in the proper location and alignment. For big-scale projects like highways, tunnelsand bridges, proper location, CCTV drainage inspection and alignment are important for making sure about the right functionality. Improper location can result in substantial issues down the line like enhanced traffic congestion, structural problems and also accidents. By making use of the latest tools and methods, construction surveying can do the right measuring and layout of the construction project, making sure that it is developed in the proper location and alignment.

Other than guaranteeing the right location and alignment, construction surveys also have an important role in making sure that the whole project is in line with the specifications of the design. The surveyors are accountable for doing verification of the dimensions as well as elevations of the infrastructure. This is vital for several reasons.

• At first, it assists in making sure that the final product is functional and pleasing, with all required features and amenities.
• It helps in making sure that the whole project is completed within the set timeframe and budget.
• It also assists in lessening the risk of legal disputes and all construction issues, which are expensive and time-consuming.

Another vital aspect of a construction survey is the role it plays in ensuring the safety of the construction project. Surveyors are accountable for recognising all hazards or obstacles that can have an impact on the construction project like the underground utilities, unstable soil and also nearby buildings. By recognising those hazards at an early stage, construction surveyors can get associated with the construction team for the development of the right solutions and make sure all are safe. This is important for big-scale projects that include heavy machinery as well as equipment and also workers and pedestrians who are near the site of construction.

The impact that the surveyors have on the construction project's success is very clear to see. It can be right to say that construction surveying is like a glue that helps hold together the project and makes sure it is completed within the right time and budget.

The data that is collected at the time of the construction survey is used for the creation of topographic maps, planning of the site and another kind of drawings that are used by the architects, engineers as well as contractors for designing and constructing. Construction surveying is vital as it helps make sure that the whole project is being on the proper location, with the right elevation and as per the required design.
