By definition, infrastructures are the fundamental facilities or physical systems designed & built to serve a city, country or other areas. These are essential for the operation of society. Some examples are transportation, telecommunication, water and electric systems. Given their role in the community, millions and even billions of dollars go into infrastructure construction projects. And each project requires intensive planning. In this post, we talk about how infrastructure surveying plays a part in ensuring each infrastructure built delivers.
Depending on the project, surveyors may need to conduct different types of surveys. One being a topographic survey. Also known as detail or contour survey, it determines and maps out the features or details of a land and its immediate adjacent areas. This includes both natural and man-made. It also checks the land’s elevations. Then if the project involves breaking ground like a dam or tunnel, government infrastructure surveyors also need to conduct an underground service location survey.
As most infrastructures are designed for complex use, very precise measurements are needed. Thus, the use of 3D laser scanning has become the standard for infrastructure surveying as it allows the gathering of much more accurate data in a time-efficient manner. It also greatly aids in creating the best design possible and helps identify and solve issues sooner.
Another task that surveyors do before construction work begins is to do a set-out survey. They do this once a design has been created for the infrastructure project. They transfer the design onto the land itself. For this type of survey, they establish key points on the land and use markers. These serve as a guide for builders during construction to ensure accuracy.
Once construction commences, surveyors continue to do a variety of tasks. These include checking and validating design data to make sure there are no errors. They also manage data for full reporting to the project contractor during each stage of construction. Furthermore, they provide documentation to support any variation claims like changes in design and quantities for unsuitable materials.
After construction has been completed, surveyors conduct a Work As Executed (WAE) or as-built survey. This survey ensures that construction adhered to the design plan as approved by the relevant authority. It compares the position and levels between the design and the actual infrastructure built.
In summary, infrastructure surveying plays a huge role in ensuring that infrastructures built do deliver. Surveyors play an important part in each project, from planning to completion. And here at Geosurv, our highly-experienced surveyors have provided their services to several clients in different states & territories particularly in Sydney infrastructure projects like the Sydney Metro Project & Sydney Harbour Bridge Toll Removal.
