Tram line extension
The 37.6km-long Light Rail Transit 3 (LRT3) is a light rail line under development in Malaysia. The line, which includes a 35km viaduct and a 2km underground tunnel, will link Bandar Utama with Johan Setia in Klang.
Prasarana Malaysia was appointed to develop and operate the line upon completion. Construction on the MYR16.63bn ($4.07bn) project commenced in 2017 and is scheduled for completion by 24 February 2024. The project cost increased to MYR31.65bn ($7.75bn), which was later reduced to MYR16.63bn ($4.07bn) after the project implementation model was changed from the project delivery partner (PDP) to the fixed price contract regime. A novation agreement was signed in February 2019 to pave the way for the change in the project model.
The light rail transit line, which is part of the Greater Kuala Lumpur / Klang Valley (GKL/KV) Land Public Transport Masterplan of the Land Public Transport Commission (SPAD), will provide connectivity to the western part of GKL/KV.
The project is expected to benefit 74,000 passengers and 500,000 residents across the alignment by improving connectivity and reducing traffic congestion. It is also anticipated to strengthen communities in Petaling Jaya, Shah Alam and Klang by promoting mixed-use real estate development around its stations.
Development of the project is also expected to stimulate economic growth in the region and create employment for approximately 2,000 personnel during the construction phase.
The LRT3 line route is divided into three main segments. The first segment will begin from Bandar Utama and end at the proposed Persada PLUS station. It will pass through Damansara Utama, Taman Kayu Ara Indah, Puncak Damansara Condominium and Dataran Prima areas.
Segment two will start from Persada PLUS Station and pass through the Temasya, Glenmarie, Shah Alam town centre, UiTM campus and I-City Station before ending at Bukit Raja. The segment will include a 2km underground section.
The third segment of the line, situated in the MPK area, will start from Bukit Raja and pass through Kawasan 17, Jalan Meru, Klang town and Bandar Botanic to end at Johan Setia.
These stations will be integrated with MRT Bandar Utama, Kelana Jaya Line, BRT Federal Line, and the KTM Komuter Port Klang Line, and feature passenger information display system (PIDS), fire protection systems, closed-circuit televisions (CCTV) and automatic fare collection (AFC) systems. The project originally envisaged the construction of 26 stations for the LRT3 line, but the number of stations was reduced to 20 with an additional five stations planned as future stations.
Ten of the stations on the line will be equipped with parking areas accommodating approximately 6,000 cars.
All stations will be equipped with sustainable solutions, including rainwater harvesting technology, noise reduction and energy management systems, and natural ventilation.
The light rail line will operate trains every two minutes. The trains will include six modular cars that are fully accessible from one end to the other. Each rail car will be 20m-long, 2.65m-wide, and 3.44m-high. The lifespan of the trains is estimated to be 30 years.
The trains will run automatically using a driverless system and communications-based train controls (CBTC). They will move at a maximum speed of 80km/h and be capable of transporting up to 36,720 passengers an hour.
The project will encompass the construction of a viaduct, elevated stations, underground stations and tunnels, and depots.
The elevated viaducts will be reinforced concrete (RC) structures situated on the road median strip and the road side. The viaducts will comprise a substructure and a superstructure, with the former consisting of pile and pile cap and the latter consisting of a box girder structure.
The elevated stations of the project will involve the construction of pile cap, column and cross head. A concourse and platform level will also be constructed.
The underground tunnel guideway and underground stations will be constructed using the cut and cover methods. Excavation will be performed for installation of excavation support or retaining a diaphragm wall, followed by the installation of tunnel top floor, tunnel foundation and base slab.
The project will also include the construction of a depot in Johan Setia and installation of utilities such as internal roads, drains, sewerage facilities, telecommunication lines and electricity cables.
MRCB George Kent (MRCBGK), a joint venture of Malaysian Resources Corporation and George Kent, was contracted to deliver design and construction services for the project in September 2015. According to the novation agreement, MRCBGK is the turnkey contractor for the project.
Mudajaya, Gabungan Strategik, Rahimkon, APEX Communications, WCT Construction, Sunway Construction, SN Akmida, Pembinaan Jaya Zira, and Trans Resources Corporation (TRC) were awarded infrastructure work package contracts.
Systra received a contract to provide preliminary designs for the project. The company will design civil engineering structures including a U-shaped viaduct, the underground section, maintenance and storage facility, railway systems, operating plans, rolling stock and a complete range of interfaces.
ERE Consulting Group prepared the environmental impact assessment report for the project. Prasarana selected a consortium of Siemens and Rasma to supply and install signalling and train control system, in February 2018. Siemens will also install a platform screen door system (PSD) and an intrusion preventive system (IPS).
