What is Included in Each Stage Inspection?

Stage Inspections
Stage 1 - Pre Slab Inspection

Pre Slab Inspection or Pre Pour Slab Inspection Perth occurs prior to the concrete being poured to create the base.

Often this stage is skipped and we are engaged to perform a slab inspection.

Here’s what we inspect:

  • Condition of the ground and foundation.
  • Installation of any necessary prelay drainage systems.
  • Level and preparedness of the soil.
  • Proper installation of concrete formwork.
  • Proper installation of any reinforcing steel in line with customer-supplied engineering.

  • Ensuring the integrity of any installed membrane.
  • Cheing wet are setdowns if applicable.
  • Ensuring adequate steel cover is prepared to avoid non-compliance offsets.
  • Ensuring termite collars have been installed in line with AS3660 and the relevant NCC.

In the case of a multi-storey construction, this pre-slab inspection process is repeated for each level prior to the concrete being poured to make sure each one is up to par and ready for the next stage of construction and often includes additional steel checks relevant to suspended slabs.

Stage 2 - Slab Inspection

In Stage 2, we have the slab inspection where we make sure that the dried concrete is of the right quality, chemical properties and if the slab has the correct dimensions.

Here’s what we inspect:

  • Layout (wet area locations and plumbing inlets).
  • Ensure concrete is cured and ready for brick load.
  • Absence of cracks or categorise cracks sighted.
  • Ensuring slab edge treatments have been carried out.
  • Footings and pier footings.
  • Full check to ensure slab and brick coursing heights are in relationship.
  • Checking for an overall level slab.
  • Categorisation of slab cracking concerning allowable Australian Standards.

  • Compliance with Australian Standard for  AS3660 Termite Management.
  • Mortar quality and allowable bed and perp joints
  • Brick bearing and allowances for load preparation.
  • Lintel bearing where visible to ensure sufficient bearing is achieved
  • Lintel setbacks, orientation and fixings to columns and piers as engineered.
  • Correct installation of wire ties, strapping, and weep holes relevant to NCC, AS3700, AS4773 and AS3660.
  • General workmanship issues such as faulty or damaged bricks, brick alignment, defective door and window frame installation.
  • Flashing above windows and required cavity brickwork to ensure proper discharge of water.
  • Plumbness and level of wall installation.
  • Step deviations in brickwork.
  • Compliance with alternative construction styles that may differ from bricks (e.g. timber or steel frame inspections are inspected to include the relevant applicable standards in place of brickwork standards)
Stage 4 – Frame Inspection

Frame Inspection or a Roof Frame Stage Inspection takes place in order to prepare the home for roof cover.

Here’s what we Inspect:

  • Roof frames are assessed using AS1684 (Steel frame roof members are assessed under the relevant Australian Standards)
    • Subfloors and timber stud homes adopt more checks in addition to the following:
    • Compliance with the latest plans and specifications.
    • Appropriate wall placement.

Lockup Inspection which often includes a Waterproofing inspection takes place as the building nears its final stages. This Inspection focuses on preparing the home for final finishings and to ensure the home will perform once finishing items are installed.

This stage of the building construction inspections Perth assesses prep quality and ensure the builder is following the building guidelines.

Here’s what we inspect:

Stage 6 – Practical Completion Inspection

Practical Completion Inspection (PCI) takes place prior to the turnover of keys to the purchaser and is the most important of all inspections. This Inspection focuses on minor defects and ensures the quality of the construction by the builder.

Here’s what we inspect:

Detailed Report with Photos

  • Following our Building Construction Inspections Perth, our independent building inspector perth issue a detailed stage report for each stage that you request along with images relevant to stage we inspect. Our reports are customised for your property and will not be a standard report, after all how can it be?
  • Each stage is treated independently as a separate report generated, this staged approach to construction inspections can save a huge amount of money and force builders to comply with NCC or National Construction Codes of Australia and put pressure on the builder to deliver a product fit for a paying and deserving customer. The small investment into Building Construction Inspections Perth always returns a higher quality build which in turn saves you tens of thousands of dollars in maintenance down the track.
  • Building Construction Inspections Perth are intended to identify bad workmanship as well as errors in the NCC application to the build, it is NOT an opportunity to pick on the builder, and if the builder is doing the right thing (we all hope they will) the report may come back with a set of images stating that inspection was carried out in a satisfactory manner, giving you ultimate peace of mind.

I found WA Building Inspections Perth very helpful. They responded quickly to my request, provided a competitive price, did a detailed report and then discussed the report with me for a lengthy period. Russel did my inspection and he could not have been more helpful in explaining the report and recommending opportunities to address findings. I would definitely go back to WA Building Inspections Perth and Russel for advice and future building inspections.

Russell’s pre-purchase report was exactly what we needed for peace of mind. He was thorough and detailed, outlining what he could and couldn’t achieve, with action plans recommended where needed! We were unsure about some wording or recommendations but Russell answered our calls and explained these perfectly and the suggested way forward. 100% worth the price, especially if you need that peace of mind at the end.

Very thorough inspection conducted by Russell. Picked heaps of defects in our roof and compiled a very detailed report about everything done wrong. He clearly explained the problems against the Australian Construction standards and code. I'd highly recommend WA Building Inspections to anyone in doubt of their house construction or before purchasing an established property. We're very lucky to have such a professional service. Worth every dollar paid.Thanks Russell & Sarah.

I had a fantastic experience with Russell recently with a pre-purchase inspection. Being interstate and purchasing was always hoing to be diffivult.I was very impressed with Russell's knowledge, patience and pride in his work. Russell took the time after working hours on the day that the report was completed to have an in depth discussion about the detail on the report. I came out of the discussion feeling a lot more confident.Russell is easy to talk to and knows how to explain complex issues in layman's terms. Can't recommend highly enough!
09:18 28 Aug 23
Best decision I made. Russell is an absolute legend. Answered all my questions, explained everything beautifully, patient, and most importantly - had my back when dealing with the builders. I had to go through 2 PCIs with the builders, finally on the 3rd did they fix all the issues. If it wasn't for Russell's knowledge and advice, I never would've gotten my house in the acceptable condition it is now. Shout out to Sarah as well for booking in my final last minute inspection, due to builders messing me around. Top shelf service and fair priced.Marina

Russell gave us genuine customer service and nothing was too much trouble.

We felt comfortable in asking questions and were given the information that we needed. Russell was very generous with his time and we would happily engage him again.

Engaged WA Building Inspections to undertake our building inspection - being based in Qld and not being able to see the house, we needed a thorough report.

I called Russell for a last minute building & pest inspection and although he was very busy, he still managed to squeeze us in. He completed a very detailed report, which both our broker and conveyancer made comments on how impressed they were with how through he was, which is a huge compliment to him and his service! I called Russell after reading the report with a couple of questions, which he took 15 minutes to explain to me everything I asked and more. He is very professional and knowledgeable, and moving forward I would only ever use his service. Sarah his admin team is also very lovely to deal with and responsive, they both made the whole process so easy! Huge compliments to them both. Highly recommend!! And very well priced.

We had a fantastic experience with Russell recently with a pre-purchase inspection. My husband and I are first home buyers and have very little first hand experience with building issues and we were absolutely blown away by Russell's knowledge, patience and pride in his work. Russell took the time after working hours on the day that the report was completed to have an in depth discussion about the detail on the report. We came out of the discussion feeling a lot more confident in our understanding of level of work required with the property. Russell is easy to talk to and knows how to explain complex issues in layman's terms. Can't recommend highly enough!

Russell McCarthy was able to fit us in very last minute despite already being booked out. We had a strict contract deadline and the outcome of his review was going to determine the success or failure of our property purchase. The fact that he went over and above to help us despite being hotly in demand demonstrates his humility and strong passion to help others which goes beyond just doing his job. He is highly rated and the best in his field yet is down to earth and genuinely kind. I will only use him going forward and recommend others do the same. A property purchase is a big financial decision and not worth risking by going to anyone other than Russell.
10:46 01 May 23
The whole process was seamless and easy from start to finish. WA BIP liaise with the agents to organise inspections and the report provided is thorough. The inspection was organised at short notice and the report was provided within a few days.The inspector (Russell in our case) took the time to explain his findings in a manner even a dummy like me can understand!I appreciated the way Russell and the team made the whole thing easy and would recommend them to anyone on the fence about who to use. Thanks!

Russell carried out the PCI (Practical Completion Inspection) for our first property (in Willetton) on Wednesday the 21st of September 2022. He conducted the inspection very professionally. He arrived well in advance at the property. So, when we went to meet him at the site he was already halfway through the inspection.After he had finished inspecting the home he discussed, both with us and with the Builder appointed Site Supervisor, about the various aspects of the inspection in plain & clear terms. The discussion was a learning experience for us (the clients) as we learnt some essential things about building structures.Inspection Report was detailed, specific and clear. Also, his T&Cs are acceptably good. Last but not least, his service is reasonably priced and is affordable. If asked I will definitely recommend him to my friends and I am confident they will thank me for recommending Russell & WA Building Inspections.

I highly recommend Russell . I chose him because of all his positive reviews and that paid off as he was so thorough and found many defects.. every dollar spent was worth it as I would have never picked up many of those faults myself and I’m extremely grateful . I also found the company was very accommodating in scheduling my inspection at short notice.

With only a limited time gap, and several other companies unable to meet the terms of contract, I tried WA Building Inspections. From the moment I could book online within 24hrs, to the very professional and prompt service from Russell, it has been a very simple process. We received a comprehensive 27 page report for a combined building and Pest report, for a awesome cost. I couldn't recommend Russell and his services more highly. Thank you so much for making this so easy for me.
