Good morning,

As some of you may be aware, ZENITH Residences, above the Coca Cola sign,
are presently having cladding removed from their building because they do
not meet the <30% legal requirement. 

We have a report, dated July 13, 2021, from Noviion Engineering, based on a
core sample which was taken from our building. I wanted to ensure that we do
in fact meet the requirements, so I read the report and became very
concerned. There is alarming information, under “Recommendation”. Please see
emails below.

I spoke to George Dahrie, the Principal Engineer from Noviion, this morning
and he stated he has been waiting to hear from us, since the initial
recommendations were made in their report to us. Presently, even though we
are <30%, from the core sample they took from our building, we still do not
meet the legal requirements. Noviion need to verify the type and brand of
cladding, which we presently don’t know. A whole panel must be removed to
find the cladding brand name.  Once we know the maker’s name, Noviion will
assess the panel (name) and provide us with engineering advice.

Darren, would you please find a suitable contractor to take out a whole
panel please and have the maker’s name given to me. I will then contact
George Dahrie and provide him with the panel maker’s name.

Unless anyone has any questions, I’m sure you’ll agree, it is essential that
we follow through with this matter asap.

Regards,

Craig

Hi Craig,

Thank you for the email.

Regarding the report, to be compliant the ACP needs to both have testing
data and <30% PE.

At the time of assessment, no information could be located to verify the
type and brand of cladding.

As such, our recommendation is to replace the cladding to meet current
Australian Standards. 

If a panel is removed and we are provided the brand, we can research the
testing data and advise on its compliance.

The cost of the assessment and engineering advice will be $2,540+GST. 

If you wish to proceed or require additional information, please do not
hesitate to ask.

Kind Regards,

George Dahrie

Dear Rick,

Client: SP 67851, Client Address 200 William Street, Woolloomooloo - Job #
21288

Thank you for your time today.

As I mentioned, I have reviewed the above job # 21288 report, and would like
to further investigate two points:

1.	The report states on page 8: “Recommendation - Based on the
laboratory results provided, it is interpolated that approximately 29% of
the core material is low density polyethylene. Polyethylene cores typically
are not fire-rated and the panels themselves would therefore not conform
with current Australian Standards. Under section 9(1) of the Building
Products (Safety) Act 2017, the act prohibits the use of aluminium composite
panels (ACP) with a core comprised of greater than 30% polyethylene (PE) by
mass in any external cladding and wall. That act states the installation of
non-compliant cladding in accordance with the act is retrospective and as
such requires to be adequately remediated. The laboratory results have
identified the Aluminium Composite Panels to have a polyethylene core
slightly less than 30% by mass. However, based on the high combustibility
and unknown manufacturer of the installed product, it is recommended that
all ACP cladding to the façade be replaced with a suitable non-combustible
material. This assessment has only considered the likelihood of Aluminium
Composite Panels (ACP) panelling being installed on the building façade.

You agreed with me that there is slight ambiguity in the recommendations.
Would you please confirm if your company is recommending that we should
remove all cladding on our building, despite the ACP having a less than 30%
mass. The report does state, because there is unknown material in the ACP,
it is Noviion’s recommendation “that all ACP cladding to the façade be
replaced with non-combustible material.”

2.	Are we required under present regulations (2023) to remove all our
cladding, because the percentages of the ACP, with a core (may) have been
reduced i.e. lower than 30% mass?

Thank you, Rick. I look forward to hearing from you as soon as possible.

Best regards,
Craig Laforest
