Waskita Karya Accelerates Construction of Jakarta LRT Phase 1B

PT Waskita Karya (Persero) Tbk has expressed its commitment to promoting safe, comfortable, and sustainable public transportation modes in commemoration of National Transportation Day. One of its efforts involves working on the Light Rail Transit (LRT) Jakarta Phase 1B from Velodrome to Manggarai.

The company is currently accelerating the completion of the project owned by PT Jakarta Propertindo (Jakpro). The realisation of the Jakarta LRT construction has reached 91.86%. The viaduct crossing over Ir Wiyoto Wiyono Toll Road is already 100% connected. Steel Box Girder (SBG) is currently being installed at the Matraman intersection.

Waskita Karya’s Corporate Secretary, Ermy Puspa Yunita, stated that the installation of the girder span is an important stage in the Jakarta LRT Phase 1B project. That section is one of the critical points on the project route.

“Waskita Karya is grateful that the entire construction process is running smoothly as planned. This success shows the strong synergy between the Company and PT Jakarta Propertindo, the local government, and stakeholders,” she said in an official statement, quoted on Friday (24/4/2026).

One of Waskita’s innovations is the use of long span (long span), including implementation methods in Building Information Modelling (BIM) up to level 7D. The implementation involves incremental lifting of Steelbox Girder, lifting sliding PC-Girder, and Traveller Launcher cast-in situ Balance Cantilever, aimed at facilitating the project work in areas with active road traffic up to toll roads that are dense in Jakarta.

“Thanks to that innovation, the installation of the LRT viaduct over the toll road is easier and does not disrupt traffic and the mobility of drivers. This proves that the Company has prioritised aspects of safety and work safety,” Ermy explained.

She explained that the Jakarta LRT elevated track from Kelapa Gading to Jalan Pramuka has also been connected. That track connects North, East, and Central Jakarta through an integrated elevated rail network.

Furthermore, several main structures in the Jalan Pemuda, Jalan Pramuka, Jalan Tambak, and Jalan Sultan Agung corridors have also been connected. Waskita Karya is optimistic that the completion of Jakarta LRT Phase 1B will be on time.

“This project has been highly anticipated by the people of Jakarta and surrounding areas because it is considered capable of reducing congestion, as well as lowering the urban carbon footprint to support better air quality,” Ermy said.

The LRT, valued at Rp4.1 trillion, is expected to be utilised soon by public transport users.

Thanks to this project, last year Waskita Karya successfully became one of the finalists in Bentley’s Going Digital Awards Year in Infrastructure (YII) 2025 held in Amsterdam, Netherlands. The Company’s digital innovation in building Jakarta LRT Phase 1B is assessed to improve efficiency, safety, and sustainability in the construction process.

In the annual event attended by 250 nominations from 47 countries, Waskita showcased technology to facilitate project work amidst dense urban areas. Ermy stated that it is not easy to build mass transportation facilities in urban areas, so innovative solutions are needed to handle field complexities.

To accelerate construction, she continued, Waskita applies digital solutions based on BIM and Bentley Systems technology. The Company also utilises drone photogrammetry and 4D simulations to monitor and manage the project in real time.

“Waskita uses an integrated digital platform that combines spatial data, BIM models, and work schedules in one system. This method aims to make it easier for all teams, both technical and non-technical, to access project information directly and make decisions quickly,” she said.

Thanks to that method, the Company succeeded in identifying and resolving more than 1,200 potential obstacles before the construction process took place.

Not only improving work safety, the implementation of 4D simulations also encourages the Company towards more efficient and precise construction methods.

“The Company is committed to continuing to innovate and support the presence of a reliable, safe, comfortable, and sustainable public transportation system. We are confident that this project contributes to creating a healthy environment and supporting Net Zero Emission (NZE),” Ermy explained.
