Setouts, As-Constructed Surveys, Height Checks & Form 12's

Certification Surveys for Brisbane Builders & Homeowners

Surveying errors during construction can create costly rework and certification delays.

A building set out in the wrong location, an incorrect slab level or a setback that does not match the approved plans can affect following trades and delay the project.

Our construction surveying services include:

  • Building setout surveys
  • As-constructed surveys, commonly called Ascons
  • Height and position checks
  • Boundary setback and clearance checks
  • Slab and finished floor level checks
  • Building and roof height checks
  • Form 12 survey certification where required.

We use Survey My Block for all of our setout, ascon and Form 12 certificates, and we never have an issue. They are always prompt to get to site and we get our projects setout or certified correctly, every time.

Today I used for the first time Survey My Block for my construction company, HiC Building Co. I came to site and noticed immediately how clear the marks and pins were and also the detail attached to the pins to say exactly what they were. For me these little details save so much time and confusion. Cant wat to use them again!.

He goes over and above what is required. Super helpful and extremely quick turnaround. Highly recommend

Building Setout Surveys Brisbane

A building setout transfers the approved design onto the site so your construction team knows where the works need to be built.

Using the approved plans, we establish the building position, offsets and relevant levels and provide clear survey marks for your site team.

Setouts can be completed for:

  • Houses
  • Townhouses
  • Duplexes and dual occupancies
  • Multi-unit developments
  • Extensions
  • Garages
  • Retaining walls
  • Other structures requiring accurate positioning

Getting the setout completed before permanent works begin helps identify positioning or documentation issues before concrete is poured or construction progresses.

 

As-Constructed Surveys Brisbane

DA for subdivision

An As-Constructed Survey, or Ascon, records where the building or structure has actually been constructed.

While a setout tells your team where the works should go, the Ascon checks the completed work.

Depending on the project and your building certifier’s requirements, we can survey:

  • Building position
  • Boundary setbacks
  • Slab position
  • Finished floor levels
  • Building dimensions
  • Roof or ridge heights
  • Other nominated construction elements

An Ascon can identify differences between the approved plans and completed works before the project progresses further.

 

Height & Position Checks

Your building certifier may require confirmation of the building’s position or height during construction.

We can undertake targeted checks for:

  • Boundary clearances
  • Building setbacks
  • Slab levels
  • Finished floor levels
  • Building position
  • Roof and ridge heights
  • Other nominated levels or dimensions

These checks can be scheduled at the required construction stage, allowing your team to confirm the works before progressing.

 

Form 12 Survey Certification

Your building certifier may require a Form 12 Aspect Inspection Certificate for a surveyed aspect of the building work.

Where the relevant requirements are met, Survey My Block can undertake the required survey inspection and provide Form 12 certification for the nominated aspect.

If your certifier has requested a Form 12, send us:

  • Approved building plans
  • Site address
  • Certifier’s inspection requirements
  • Relevant approval documents
  • Current construction stage

We can review the information and confirm what survey work is required.

An As-Constructed Survey records the actual position and levels of completed construction and allows nominated elements to be checked against the approved plans.
