A contour survey, also known as a site survey, detail survey, or feature topographic survey, is a specialized type of land survey that maps the topography of a site, showing the shape and elevation of the land. It is crucial for construction, renovation, and development projects, providing detailed information about the land's features and elevation levels. 

Key aspects of a contour survey: 
Contour lines:
These are imaginary lines connecting points of equal elevation on the land's surface. 
Purpose:
Contour surveys are used to visualize the terrain, understand slopes, and plan for building placement, drainage, and other site works. 
Importance:

They are essential for architects, engineers, builders, and certifiers to understand the existing site conditions before starting a project. 
Features:
Contour surveys include details of buildings, trees, services (sewerage, drainage, etc.), roads, and other visible features. 

When Needed:
Contour surveys are often required for new land developments, construction projects, landscaping designs, and subdivision proposals. 

Benefits:
They help maximize lot yield, prevent design conflicts, and avoid costly mistakes during construction. 
In essence, a contour survey provides a detailed, three-dimensional representation of a site's topography, enabling informed planning and design decisions for various land development projects. According to Brighton Homes, this information is invaluable for visualizing the site, planning site works, and designing efficient drainage systems.
