Shear strengthening of beams using CFRP wrap at a bungalow Jun 2006, Singapore
The house owner decided to change the layout of his house which resulted in additional load on the beams. CFRP wrap was selected because of its fast process and readiness to increase the load capacities of the wrapped beams.
Flexural & shear strengthening of beams
using high-strength CFRP wrap at NTUC Shopping Mall Mar 2006, Singapore
The shopping mall will increase the number of shops to be rented and change the purposes of usage such as spa and health centres. Strengthening of six beams was awarded to FOSTA to increase shear and flexural loading capacities of the said beams using carbon fibre reinforced polymer (CFRP) wrap.

The flexible installation schedule and almost zero addition of weight to the existing structures provide great advantages to the building alteration work. The owner chose CFRP method because of: no hacking - no noise, flexible installation schedule, fast, and money saving.
Strengthening using CFRP, corrosion and structural monitoring of beams, slabs and
pile caps of container decks of a sea-port 2003 ~ 2005, Singapore
Marine concrete structures suffer seawater corrosion, especially under tidal splash zone, which causes spalling concrete and corroded rebars. The sea-port operator decided to stop further corrosion and strengthen the corroded structures such as slabs, beams and pile caps.

Special formulated CFRP system was used to wrap the structure to stop further seawater corrosion. Mini sensors were embedded in the CFRP wrap to monitor corrosion rate and evaluate corrosion levels. Fibre optic sensors were embedded in the CFRP wrap to monitor structural behaviours of the strengthened concrete structures.
Development of CFRP wrap system for HDB columns Mar ~ Dec 2002, Singapore
Fibre reinforced polymer (FRP) systems are used to wrap HDB columns. A project was carried out to develop a composite wrapping system for the HDB columns. Comprehensive aspects were studied to obtain optimum strengthening effects: various wrapping patterns, fibre angles, fibre weaving patterns, the number of layers, tensioning of fibre during application, fibre overlap length, scaled-down column testing with and without wrap, etc. We achieved 20~41% increase of axial load capacity by using various wrapping designs.
