The Kelana Jaya LRT line, in operation since September 1998, extends around 29km connecting Kelana Jaya, Kuala Lumpur and Gombak.
In 2010, extensive structural cracks developed along the abutment walls and diaphragm beams in the stretch near Setiawangsa LRT station and piers and pile caps along the stretch near Asia Jaya and Tun Sambathan stations.
JTK Consult (JTK) provided the remedial design and supervised the remedial works on site. The works involved installation of carbon fibre plates to beams, crack injection and anti-carbonation coating for the abutments and piers, and enlargement of pile caps.
