Building collapse continue to dominate industry events over the past few years. There are many defective buildings waiting to collapse and the owners of some of these buildings are not particularly sure which way to go in fixing the problem.

Apart from being counter-productive investment-wise and attracting attention in a negative way, having a defective/sick building can cause the owner to be just as sick as it is because of the inconveniences that it brings coupled with uncertainties and strings of complaints.

What readily comes to mind or the popular advice is ‘bring it down and rebuild’. This demolish and rebuild option is often very expensive and can be really wasteful, even though some others argue that it gives birth to something new. What difference does it make? Using underpinning and retrofits techniques, a defective building can be restored completely and made to look astonishingly new at a much reduced cost

Sometimes owners of such properties are forced to sell them at some incredible prices just so that they do not continue to endanger the lives of the building occupants as well as to avoid incurring the wrath of the law should it collapse.

But having worked on a couple of defective buildings over time, my team and I have discovered that not as much money and time is needed to put these kinds of buildings back in shape using underpinning techniques as it will take to pull down the entire structure and re-build.

For instance, it only cost about 8 Million Naira to underpin and retrofit a defective block of 4 flats located on the Lagos mainland completed in less than 7 weeks. However demolishing and rebuilding would have cost not less than 20 Million Naira; that’s a whopping 12 Million Naira difference which is enough to build two units of 3-bedroom bungalows extra. Besides it is common knowledge that it would take a longer time to complete.
