JTK Consult (JTK) was engaged by Glenmarie Properties Sdn Bhd a subsidiary of DRB Hicom to undertake an assessment of a high rise student accommodation showing signs of distress in Pekan, Pahang.
Problems of cracking and concerns for concrete strength were investigated. The concrete cube test results confirmed that the concrete in general did not meet the specification requirements. The in-situ core testing further confirmed shortfalls in the concrete strength.
Remedial proposals were made as part of the upgrading works to the beams, shearwalls and slabs:
– For beams some intervention was proposed at roof level
– For shearwalls regular maintenance inspection was proposed to manage the risk of long term cracks.
– Slab strengthening was required where the concrete thickness was less than the design limit of 150mm.
