[200WILLIAM-EC SP67851] Building report

[Craig Laforest]

Hello everyone,

I would like to highlight that concrete cancer is not a simply issue

As you may be aware, concrete is a porous material and when used for
construction, reinforcing steel is inserted to bolster its strength.
Since concrete is porous, it can absorb water and salt air very
easily, which corrodes the steel inside. This process is what gives a
structure concrete cancer. When water is absorbed through the
concrete, along with salt air (which the report mentioned), the result
is concrete cancer. When the cancer appears, it's because the steel
inside the concrete, expands. When it expands, it cracks the
concrete.  I have it in numerous areas on my deck and on the window
ledges. Rusting steel angles are considered concrete cancer. We do not
have render inside the concrete. We have steel, which is exposed in
many places.

We must attack this problem ASAP.
Cheers,
Craig

Hi Kylie. 
  No I have requested a quote to create a scope of work. Once we
agree to that quote a scope and technical specifications can be
created. We can then use those specifications to put the work out to
tender and then we can have a GM to adopt one of the quotes and
generate either additional budget or a special levy. 

 I have never seen any “concrete cancer” in this building.
Concrete cancer typically refers to corrosion in steel reinforcement.
Our building is brick with render. As far as I’m aware the only
place we could have concrete cancer is in the slabs between floors and
there has never been any indication of that.  There’s some rusting
steel angle but that’s not concrete cancer. What we are talking
about here is cosmetic and waterproofing not structural as concrete
cancer can be. 

 Warm regards 
 Matt

Thank you Matt.

 Will the engineer follow up with quotes for the works that need to be
carried out immediately?

 It looks like there’s a lot of work to be carried out and I note
the images and points around rust and moisture in the facade and
building but I don’t see anything about concrete cancer, unless
I’m missing something?

 Warm Regards,
 Kylie

 Hi All,
 You can download the building report from the included link. It's to
big for email. There's nothing unexpected there that I can see. I have
ask Sarah to follow up and get a quote for the work to generate the
technical spec for rectification which can be used for the tender
process.

 Warm regards
 Matt
