INTRODUCTIONDepartment of NafAll conducted an immediate investigation
The results published in this report, showed that: The Narfarkle building collapsed
due to construction flaws.
This problem may be widespread in similar buildings.
INTRODUCTIONThe report also forecasts that the incidence may rise (as flawed buildings get older)

SOLUTION
INTRODUCTION In particular, this presentation will:
Explain the reason for this danger; and
Describe a low risk approach to alleviate this threat (quickly & efficiently)
We’ll cover this as: Background (Reason for the Problem)
Solution (A straightforward approach to control your risk)
Open Discussion (happy to cover issues in detail)
Because time is short, could you please hold your questions until the Open Discussion
(unless really pressing)
BACKGROUND
BACKGROUNDReasons identified by the Dept of NafAll .
Construction methods from 1970s to 1990s (many Big Co buildings constructed in this period)
‘Slump’ requirements lower than today
Made it easier to work, but not as strong
Concrete has become more porous over time
Leading to corrosion of the rebar and stirrups
Weakening the foundations & floors
BACKGROUND How does this happen? (let’s look at the construction)
Moisture builds up in the porous heart
This corrodes the rebar & stirrups
Meaning that the structure is more likely to fail
Formwork
Stirrups (Holding Rebar into centre of concrete)
Rebar (Reinforcement)
Concrete
Moisture Build Up Over Time
BACKGROUNDThis conclusion is based on substantial study of internal structures (the Narfarkle Building and many others)
They identified that this problem is widespread (as described shortly)
For example:
This is a failed joist from the Narfarkle Building
This shows how the joist
literally shattered
This is a magnified picture of the same joist just three months earlier
Light marking & surface
cracking is all that was visible(Yet there was Severe unseen
Wastage)
BACKGROUNDThis level of corrosion can be directly linked to the construction (e.g. type of concrete & methods)
And many of your buildings may be suffering the same problems (e.g. the building we are in now)
Let’s look at the reason for this in more detail

The Narfarkle Building<60% of original dimensions
13This building could have this level of degradation
BACKGROUNDMany buildings may therefore be at risk (Many of Big Co’s offices may be affected by this building cancer)
The risk of collapse may be rising because: Weakness in the concrete (it becomes porous)
Increased moisture held in the concrete
The moisture is corroding the rebar & stirrups (so the buildings are weaker & collapse)
Your buildings may be at very real risk (and nobody would know).
SOLUTION
THE SOLUTION There is a simple solution to reduce your risk You can initiate this immediately and
complete the work in around 3 months Three straightforward steps:
Step 1 – Engineering Survey and Report Step 2 – Go out to tender (if required)
Step 3 – Implement the Solution (solution can typically be fitted in around 4 weeks)
So you can rapidly reduce your risks, and save money lives and assets.
Step 1Engineering
Survey & Report
1 – SURVEY & REPORT You can quickly scope your risks (by getting a
detailed engineering report)
There are 3 Phases in this process Phase 1 – Use the latest structural
hydrometer (assess the level of moisture in cement)
Phase 2 – Where moisture is high – use latest generation structural scanning (assess level of corrosion)
Phases 1 & 2: Typically takes about half a day per floor Can be done at night time (to reduce disruptions to your
staff)
1 – SURVEY & REPORT Phase 3 – A detailed report can then be
created in a few days So this can be a very quick process
if you select the right contractor This means you can:
Rapidly assess the extent of your risk (before you have to commit to additional expenses)
Use this as a starting point which really works (it has been used successfully by BUF on numerous occasions)
Step 2Go to Tender
2 – GO TO TENDER Where a problem is identified you can go out
to tender (to select the right organisation/solution)
This can be done quickly (using your normal
tendering process) because: There are only two products that can fix this
problem
S W I F T Crappolo Widgets
FlakeCo
We can provide the information you need to fast track your analysis (e.g. industry benchmarks, standards, etc.)
2 – GO TO TENDER Where a problem is identified you can go out
to tender (select the right organisation/solution)
This can be done quickly (using your normal
tendering process) because: There are only two products that can fix this
problem
I will be happy to discuss these afterwards
Step 3Implement
Solution
3 – IMPLEMENT SOLUTION
You can initiate rapid rectification (for buildings at risk)
To explain the approach – I will use the timeline for MidCo (they had similar problems resolved just a couple of months ago)
They had 8 Buildings with Advanced Structural Decay (including the one shown here) & a further 20 at risk
BUF was selected through open tender; and rapidly fitted SwiftSure (to stabilise & strengthen)
3 – IMPLEMENT SOLUTION
The process we used entailed:
Prioritising the work (focussing on offices at the most risk)
Fitting SwiftSure (using the Quality processes & systems I will describe shortly)
Fitting low-cost SwiftSure to other buildings not at risk (providing much longer building life to MidCo)
Fitment ProcessS W I F T
SwiftSure Fitment Process There are five stages:
Stage 1 – Drill holes in the right location (precision drilling)
Here is the Cement flooring we looked at earlier
SwiftSure Fitment Process There are five stages:
Stage 1 – Drill holes in the right location (precision drilling)
Stage 2 – Fitting the SwiftSure Super Widgets
SwiftSure Fitment Process There are five stages:
Stage 1 – Drill holes in the right location (precision drilling)
Stage 2 – Fitting the SwiftSure Super Widgets Stage 3 – Backfilling the holes and capping them (allowing
the moisture to be channelled out)
SwiftSure Fitment Process There are five stages:
Stage 1 – Drill holes in the right location (precision drilling)
Stage 2 – Fitting the SwiftSure Super Widgets Stage 3 – Backfilling the holes and capping them (allowing
the moisture to be channelled out) Stage 4 – Power up SwiftSure (extract moisture)

This process literally makes the building stronger.
SwiftSure Fitment Process BUF can therefore readily assist Big Co to
repair any buildings that may be at risk, by:
Fitting the SwiftSure system to remove the moisture; and refurbish the structural integrity
Fitting this system to buildings at lower risk - to improve the life span of your offices
Which can deliver very real benefits
SwiftSure Fitment Process As illustrated by this quote from the CEO of
MidCo
By fitting SwiftSure, MidCo was able to repair our buildings quickly. We have also used SwiftSure to extend the life for all of our buildings. By fixing the affected buildings and continuing the life of all of our buildings, we have saved more than $2 Billion.
F.G. Fungun – CEO MidCo
So What Does this Mean for
You ?
You can minimise your costs: Low cost of Engineering Survey and Report Readily Scope your risk (so you focus only on the work that
needs to be done, to reduce costs); and Your tendering system can be used to identify the best
solution (identifying the best value for money)
You can minimise your risks: Identify problems before a catastrophe occurs. Tendering risks are greatly simplified as:
You only need to assess 2 products; and We can provide industry standard and benchmark
information (to facilitate your assessment)

CONCLUSION
CONCLUSION There is a very real danger that your buildings
may collapse.
As identified by the Department of NafAll
You can rapidly reduce your risks by: Step 1 – Engineering Survey & Report
(identify risk rapidly)
Step 2 – Go to Tender (quick & easy)
Step 3 – Implement Solution (with the solution you select)
CONCLUSION Should you select SwiftSure, this system:
can be fitted rapidly (~ 4 weeks)
Makes your office blocks stronger (even after severe degradation)
Is low cost and low risk solution (proven, advanced & reliable)
Is well supported by the BUF team (so you can just leave it to us)
CONCLUSION By implementing this solution quickly, you can
save: Money. Lives . Your key assets (the buildings and their contents).
More importantly, you can achieve these outcomes through: a low risk and low cost approach; that can save you a great deal of time and effort; and is likely to be seen as a major benefit by Big Co.
RECOMMNDATION It is therefore recommended that:
you get an engineering survey & report as soon as possible.
you go to tender quickly (if required).
get any identifiable problems resolved quickly.
So you can avoid the same fate as
the people in the Narfarkle Building
