Site set out is the process of transferring building measurements and plans from drawings onto the ground before construction begins. It helps ensure walls, footings, trenches and structural elements are positioned accurately according to the approved plans.

Accurate building set out is one of the most important early stages of a construction project. Mistakes during set out can lead to alignment issues, excavation errors, delays and costly rework later in the build.

Back to Basics supports construction professionals through practical training focused on site survey, set out and construction accuracy processes used across residential and commercial projects.

Prepare the site and tools

The first step to a building set out is ensuring the site is cleared, levelled where needed, and checked against drawings. Common tools include tape measures, total stations, pegs, profiles, string lines, and marking paint. Accurate preparation is essential, as mistakes at this stage affect the entire build.

Establish control points

Control points act as fixed reference markers across the site. These are set using surveying equipment to align with the design coordinates. From these points, all measurements for the site set out are taken, ensuring the structure matches boundaries and approved plans.

Mark the building layout

With control points in place, the building outline is marked on the ground. Pegs and string lines define walls, corners, and trench positions. Diagonal checks confirm squareness and alignment. This step ensures the building set out accurately reflects the construction drawings.

Ensure final checks and accuracy control

Before excavation begins, all measurements are rechecked using surveying instruments. Levels, distances, and angles are verified to avoid costly errors. A precise site set out ensures construction proceeds smoothly and according to specification.

Why accurate site set out matters

A well-executed site set out supports smoother construction processes from the beginning of the project.



Accurate set out can help:

• Reduce costly rework
• Improve construction efficiency
• Support structural accuracy
• Minimise delays during excavation and footing stages
• Improve coordination across trades and contractors

These processes are an important part of residential, commercial and civil construction projects across Australia.
