A construction survey is a type of survey that is performed during the construction phase of a building or infrastructure project. It involves the precise measurement and mapping of the site to ensure that the construction work is being carried out according to the approved plans and specifications.
A construction survey typically includes the following tasks:
Construction surveys are an important part of any construction project, as they help to ensure that the work is being carried out accurately and according to the approved plans. They also provide a record of the completed project for future reference.
A building set-out is undertaken to transfer the building design onto the land by providing markers at key points to enable the builder to construct the building as detailed in the architectural plans.
When the formwork for the building has been created a slab check is carried out prior to the concrete pour. Measurements are confirmed to ensure the slab is consistent with the plans.
An as-built survey records the location of the improvements on the land “as built” in comparison to the original design. This may include improvements such as sewer pipes, buildings, utilities, pavement, etc.
As with a building set-out, the column and pile set-out are a transfer of the building design onto the land. Markers are set out to enable the accurate placement of columns and piles for the building during construction.
Work-as-executed surveys are carried out to ensure that the completed works conform to the approved design plans. Councils require that a work-as-executed survey, prepared by a Registered Surveyor, is provided prior to issuing an occupation certificate to the owners of the property.
A final survey is carried out when the building work is completed. A final survey shows the location of a new structure on the property. It includes information such as roof height, floor level, the position in relation to boundaries and any encroachments onto neighbouring properties.
We provide a range of construction surveys on a daily basis, all our surveys are supervised and signed by a Registered Professional Land Surveyor.
We have extensive experience in all types of work from small, residential surveys to complex, large-scale commercial projects and we specialise in small to medium residential subdivision projects (2-650 lots)
