Progress Reaches 93.07 Per Cent, Waskita Karya Accelerates Jakarta LRT Phase 1B Construction
PT Waskita Karya (Persero) Tbk, in collaboration with PT Jakarta Propertindo (Perseroda), has recently initiated the Testing and Commissioning (T&C) series for the Jakarta LRT Phase 1B (Velodrome-Manggarai) railway system.
Iwan Takwin, President Director of Jakarta Propertindo (Jakpro), stated that one of the testing sequences involves track tests along a 3.6-kilometre stretch connecting Velodrome Station to Pramuka Station. He explained that the T&C stage is being conducted in a detailed manner to ensure all systems are ready for use. This process includes systematic and structured testing of all components and subsystems—ranging from tracks, signalling, and electricity to communications and operational integration—before commercial operations begin.
“Every metre of the Jakarta LRT Phase 1B elevated track is our responsibility to the people of Jakarta who will rely on the LRT daily. Therefore, this T&C stage must be prepared very thoroughly,” Iwan said in a statement on Wednesday, 3 June 2026.
Paulus Budi Kartiko, Director of Operations II at Waskita Karya, noted that Waskita’s involvement in the Phase 1B development extends beyond mere construction, serving as an opportunity to showcase the company’s capabilities. “This high-visibility project means that the quality of work directly impacts our long-term reputation,” said Paulus.
He further explained that Waskita’s scope of work for the Jakarta LRT Phase 1B includes the integration of civil works, rails, systems, and operations. Waskita is continuing to accelerate construction to ensure the project can be utilised by the public as soon as possible, with the Rp 4.1 trillion project currently reaching 93.07 per cent completion.
“During the construction process, the main challenges (urban constraints) we face as a contractor include Jakarta’s heavy traffic and limited workspace,” Paulus added. “As a solution, we are optimising working hours at night, which demands focus and innovation in safety and work systems. We view this as a constraint to be managed, not avoided.”
Regarding the track testing, Paulus noted that one of the areas traversed includes the crossing above the active Wiyoto-Wiyono Toll Road, from kilometre 1+700 to 2+100. To ensure that traffic on the toll road remains undisturbed during the construction period, Waskita has utilised an innovative balance cantilever method with a span of 120 metres.
