Construction Surveys on the Sunshine Coast

Set Outs, As-Constructed Surveys, Height Checks & Form 12 Certification

A slab poured 20mm out of level, a setback that doesn’t match the DA, or a building corner in the wrong spot — these are the surveying mistakes that stop a Sunshine Coast build in its tracks. Certifiers won’t sign off, trades get held up, and rework eats into your margin.

Survey My Block runs construction surveys across the Sunshine Coast for builders and homeowners who’d rather catch a problem before the concrete goes down than after.

What we cover:

  • Building set out
  • As-constructed (Ascon) surveys
  • Height and position checks
  • Boundary setback and clearance verification
  • Slab and finished floor level checks
  • Roof and ridge height checks
  • Form 12 Aspect Inspection Certificates

We work the whole coast including Maroochydore, Mooloolaba, Buderim, Caloundra, Noosa, Coolum, Nambour, Sippy Downs and Kawana included.

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!.

Set Out’s: Getting the Build in the Right Spot From Day One

site surveys sunshine coast

Before anyone can start building, the approved plans need to be translated onto the actual block, building corners, offsets, and levels pegged out so your crew knows exactly where to work.

We handle set out for:

  • New houses
  • Duplexes and dual occs
  • Townhouse and multi-unit sites
  • Granny flats and extensions
  • Garages, sheds and retaining walls
  • Pools and other structures needing accurate positioning

 

A set out picks up plan errors, boundary discrepancies, or clashes with easements while they’re still cheap to fix (not once footings are in).

 

As-Constructed Surveys (Ascons)

Set out tells the crew where to build. An Ascon checks what they actually built.

Once works are underway or complete, we survey the built form against the approved plans and flag anything that’s drifted, position, level, dimensions, or height. Depending on what your certifier needs, this can cover:

  • Building position and footprint
  • Boundary setbacks
  • Slab position and level
  • Finished floor levels
  • Roof or ridge height
  • Any other element nominated by your certifier

Catching a discrepancy at Ascon stage, rather than at final inspection, is usually the difference between a quick fix and a costly one.

Height & Position Checks

Some certifiers want confirmation at specific stages rather than waiting for a full Ascon. Slab down, frame up, roof on.

We can attend site for a targeted check of whatever’s been nominated:

  • Boundary clearances
  • Building setbacks
  • Slab or finished floor levels
  • Building position
  • Roof and ridge heights
  • Other stage-specific requirements

These can be booked around your build schedule so the relevant trade isn’t left waiting on a survey result.

Certification Survey FAQ's

What plans do you need for a building setout?

Send us the latest approved architectural or construction plans showing the proposed building position, dimensions and relevant levels.

We may also require engineering plans or other approval documents depending on the project.

It's the standard survey used to start house plans, renovations and site designs.

When should I book the setout?

Book the setout before permanent construction works begin.

For projects with tight construction programs, contact us early so the survey can be coordinated with your footing or slab program.

What is an Ascon survey?

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

What is the difference between a setout and an Ascon?

A setout marks where the works should be constructed.

An Ascon measures where the works have actually been constructed.

Can you check building setbacks and heights?

Can you check building setbacks and heights?

Do you provide Form 12s?

Yes, for relevant survey aspects where the required appointment and certification requirements have been met.

If your certifier has requested a Form 12, send us their requirements and the approved plans.

Can you handle multiple projects for our building company?

Yes. We work with builders and developers requiring construction surveys across multiple Brisbane sites.

Send us your upcoming projects and survey requirements and we can discuss an ongoing arrangement.
