INTRODUCTION Department 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.
INTRODUCTION The report also forecasts that the incidence may rise (as flawed buildings get older) BIG Cos Buildings Which are of similar construction to the Narfarkle Building (Shown by Age) 31 2 46 8 7 511 12 10 9 14 1315 Each dot denotes one of Big Cos buildings, which is similar in construction to the Narfarkle Building 05101520253035 0% 10% 20% 30% AGE OF BUILDINGS IN YEARS Forecast Increased Probability of Catastrophic Failure This is the building we are in now Narfarkle Building 13 DANGER ZONE
INTRODUCTION This presentation will: Demonstrate that Big Cos buildings may be in danger of collapsing. Explain how you can save money, lives and assets (by reviving your buildings with SwiftSure). PROVEN LOW COST 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) Well 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)
Reasons 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? (lets 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
BACKGROUND This 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)
BACKGROUND This 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) Lets look at the reason for this in more detail
REASON 1 As the concrete ages it becomes more porous (Narfarkle Building concrete under a microscope) Source: Page 7 of the NafAll ReportSource: Page 12 of the NafAll Report High Elevated Moderate Low More than 50% chance of being at risk
REASON 2 Due to porous concrete - the level of moisture rises rapidly Source: Page 16 of the NafAll Report Nearly 7 times as much Moisture after 30 Years
REASON 3 Increased moisture leads to corrosion of the steel reinforcement (as shown in this graph) Source: Page 18 of the NafAll Report The Narfarkle Building <60% of original dimensions 13 This building could have this level of degradation
BACKGROUND Many buildings may therefore be at risk (Many of Big Cos 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).
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.
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)
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 Crappolo Widgets
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
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)
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) Moisture Removal Spigot
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) Stage 5 – Leach polymer into structure (new & advanced) Polymer Injection Port makes the concrete more impervious (e.g. to moisture); bonds with the reinforcement, and
SwiftSure Fitment Process Creates increased load bearing strength (strengthening both the reinforcement and concrete) Source: Independent Report from WhoZat Enterprises Original Strength of Material Strength of material after 22 years (prior to SwiftSure Application) Strength of material in the six months after SwiftSure Application 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
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) What does this Mean ?
Week 1 Week 2 Week 3 Week 4 Week 5 Week 6 Week 7 Week 8 Week 12 Week 9 Week 10 Week 11 This approach therefore reduces costs, risks & workloads It is also very quick to implement What does this Mean ? ENGINEERING SURVEY & REPORT REPORT ASSESSMENT Step 1 PREPARE TENDER (BASED ON INDUSTRY STANDARDS) DEVELOP TENDER RESPONSE TENDER RESPONSE ANALYSIS CONTRACT NEGOTIATIONS & PLANNING Step 2 FITTED SWIFTSURE (IN ALL 8 BUILDINGS AT RISK) Step 3 You can quickly identify the level of risk. Tendering will be quick (2 products & benchmarks) Fit the solution in around 4 weeks.
Would you agree that the key to your selection is surety ? This is where SwiftSure can help to reduce your risks. (as illustrated by this independent assessment by WhoZat Enterprises) THE KEY CRITERIA Scores out of 10 SwiftSureCrappolo Widely Used83 Reliability of Solution/System96 Effectiveness of the System95 Application of Advanced Technology86 Quality of Materials105 Quality of Systems & Processes (for fitment) 94 Cost Effectiveness93 Overall Rating (Out of 10)8.84.5 Source: Independent Report from WhoZat Enterprises, p. 14 You can therefore rely on a proven and reliable Product.
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
