Nearing Completion, Jakarta LRT Phase 1B Progress Reaches 91 Percent

Jakarta (ANTARA) - PT Waskita Karya (Persero) Tbk has recorded progress on the Light Rail Transit (LRT) Jakarta Phase 1B from Velodrome to Manggarai at 91.86 percent.

Corporate Secretary of Waskita Karya, Ermy Puspa Yunita, stated that the elevated LRT track crossing over Jalan Tol Ir Wiyoto Wiyono has been fully connected at 100 percent, and Steel Box Girder (SBG) is currently being installed at the Matraman intersection.

“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 track,” she said in a statement in Jakarta on Friday.

Ermy explained that Waskita is implementing the use of long spans, including execution methods in the implementation of 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 tollways that are dense in Jakarta.

“Thanks to that innovation, the installation of the elevated LRT track over the toll road is easier and does not disrupt traffic and the mobility of motorists,” she said.

Furthermore, she stated that the elevated LRT track in Jakarta from Kelapa Gading to Jalan Pramuka has also been connected.

That track connects North, East, and Central Jakarta through an integrated elevated rail network.

Next, 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 is highly anticipated by the people of Jakarta and its surroundings because it is considered capable of reducing congestion, while also lowering the urban carbon footprint to support better air quality,” said Ermy.

Then, to accelerate development, she continued, Waskita applies digital solutions based on BIM and Bentley Systems technology.

The company also utilises drone photogrammetry as well as 4D simulations to monitor and manage the project in real time.

“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 has successfully identified and resolved more than 1,200 potential obstacles before the construction process takes place.

Not only does it improve work safety, the implementation of 4D simulations also encourages the company towards more efficient and precise construction methods.
