- Failure Mode and Effect Analysis (FMEA) of constructed detail at SOTA
In preventing failure, an FMEA was conducted at School of The Arts (SOTA, Singapore) to analyze features with potential failure.

- Glass Failure Investigation
In this aspect, we have been called in to investigate numerous glass failure cases. We employ macroscopic and microscopic techniques
in these investigations.
- Material Failure Investigation
We have investigated failure of many materials in buildings including waterproofing, stone (marble, granite etc), sealant, epoxy, plaster, paint etc.
In these investigations, we employed many techniques including petrography, scanning electron microscopy, Fourier Transform Infrared and many more.
- Petrography - which is a detail microscopic analysis of minerals and rocks are often employed to in many of our investigation.
This highly fine analysis are able to discern numerous clues embedded in the sample. However, this can only be conducted by
trained petrographer. Below are 2 samples of petrography investigation of epoxy failure
- Debonded screed and waterproofing failure investigation
- Analysis of corroded food waste cement-lined pipe
Other building system defects which we have investigated include water seepage, mould growth, swimming pool staining,
water feature corrosion etc.
- Indoor air contamination - Investigation on mould growth and bug infestation.
- Swimming pool water contamination due to grout failure.
- Buckling and debonding of marble tiles.
- Diagnosis of dampness in building cause unsightly external facade.
Infra red thermography is used to detect cold spots and sites of poor sealing and leakages.
- Cracking of ceramic wall tile. In certain case, tile cracking could be induced by poor poor construction of backing.
- Cracking in concrete slab is investigated using petrographic examination.
