What is the primary concern of construction surveys?

The primary concern of construction surveys is the placement of horizontal and vertical control for building activities. This aspect is vital for ensuring that construction projects are executed accurately according to design specifications. Proper horizontal and vertical control establishes a reliable framework for the project, allowing builders to position structures, roads, utilities, and other elements precisely within the defined design parameters.

Having accurate control points is crucial for coordinating all stages of construction and maintaining alignment and elevation as planned. This helps avoid costly mistakes and rework during the construction process. Accurate placement also ensures compliance with local regulations and standards, leading to successful project completion.

While establishing property boundaries, conducting topographic surveys, and measuring environmental impact are all important tasks related to surveying, they fall into specific contexts or phases of a project. They do not primarily emphasize the critical control necessary for the ongoing construction process, which is why placement of horizontal and vertical control holds the main focus in construction surveys.
