Setting out a new build: explained step by step
At the start of a new construction project, correctly positioning the home on the plot is crucial. This is done through the setting out of the new build, a surveying procedure in which the exact location of the home on the site is established. In this article, we explain exactly what that entails and how this process proceeds step by step.
What does setting out a new build mean?
Setting out means that the planned home is accurately transferred from the design to the site by a land surveyor. The land surveyor determines where the corners of the home are located, taking into account plot boundaries, building lines, and building regulations. This forms the basis for foundation works and further construction activities.
Step 1: Measuring the existing situation
The process starts with measuring the existing situation of the plot. In this process, terrain heights, plot boundaries, and relevant elements are recorded using surveying equipment. This data forms the basis for correctly positioning the construction project and avoiding potential conflicts or deviations.
The measurement data is processed into a digital plan of the existing situation.
Step 2: Drawing in the new build
Based on the survey, the new-build home is digitally drawn in. This involves checking whether the design aligns correctly with the plot boundaries, building lines, and applicable regulations. This allows any errors or ambiguities to be detected and corrected in advance, even before setting out on the site.
After approval of the plan, the setting-out work can begin.
Step 3: Setting out the corner points
During the setting out, the exact corner points of the home are marked on the site. These points determine the location of the foundation and are essential for a correct start of the construction works.
The land surveyor uses precise measuring equipment to ensure that the home is placed exactly according to the plan.
Step 4: References for the contractor
In addition to the corner points, reference points are also placed at a fixed distance from the home. These remain visible during excavation and foundation works and enable the contractor to maintain the contours of the home correctly, even when the original markings temporarily disappear.
Why accurate setting-out work is essential
Correct setting-out work prevents:
- deviations in the position of the home
- problems with permits or plot boundaries
- extra costs due to repairs or adjustments
Accurate setting out ensures that construction can start smoothly and proceed correctly according to the approved design.
When do you engage a land surveyor?
The land surveyor is engaged:
- before the start of foundation works
- after approval of the building plan
- when absolute certainty is required regarding the location of the home
If there is any doubt about plot boundaries or building lines, it is advisable to have this checked in a timely manner.
