LRT3 Construction The New Way Forward

Summary

The LRT 3 project aims to enhance connectivity across Klang Valley by constructing state-of-the-art stations and viaducts using advanced techniques like Utrecht technology, which minimizes disruption and accelerates construction. The project emphasizes safety with meticulous planning, including traffic management, safety barriers, and competent crane operators. Key activities involve piling, foundation works, viaduct installation, and station construction, all while ensuring minimal impact on the public. The stations, inspired by national and cultural identities, focus on energy efficiency, natural lighting, and commuter comfort, reflecting a blend of modern engineering and sustainability.

Q & A

What is the primary goal of the LRT 3 project?

The primary goal of the LRT 3 project is to connect two million people across the Klang Valley, enhancing the connectivity of the urban rail system and bringing communities closer together.

What are the key activities involved in the LRT 3 construction?

The key activities involved in the LRT 3 construction include the construction of piers, viaducts, and stations, as well as various preparatory tasks such as utility relocation and pavement widening.

What is the purpose of the safety barricades along the construction site?

The safety barricades are deployed along the construction site to ensure the safety of road users, prevent debris from entering the roadway, and maintain a safe distance between the worksite and the public.

How will traffic be managed during the construction of LRT 3?

Traffic will be managed using the stop-and-go method, with careful monitoring and management to ensure safety. There will also be measures like variable message signage and super cones to direct traffic flow.

What construction technique will be used for the foundation of LRT 3?

The foundation for the LRT 3 will be built using board piling, a modern technique, with sheet piles installed to provide additional support and retain the soil.

How does the Utrecht technology improve the construction process of the viaducts?

The Utrecht technology enables faster construction of viaducts, allowing at least one span to be installed in a day compared to three days using the traditional segmental box girder method. It also integrates noise barriers to minimize disruption.

Why are the concrete spans for the viaducts precast off-site?

The concrete spans are precast off-site to reduce the need for infrastructure on-site and ensure that the construction process is more efficient and less disruptive to the surrounding areas.

When will the viaducts be installed, and why is this timing important?

The viaducts will be installed at night to minimize disruption to traffic and ensure the safety of road users. Traffic flow will be contained in a single lane, while the other lanes will be used for cranes and trailers.

How will safety be ensured during the installation of the viaducts?

Safety will be ensured by escorting the concrete spans with lead riders, clearance riders, and LRT 3 vehicles. Strict safety protocols will be followed, and all cranes will be operated by certified personnel with more than five years of experience.

What is the design concept for the LRT 3 stations, and how does it relate to national identity?

The design concept for the LRT 3 stations incorporates elements of Malaysia’s national and cultural identity. The open space on the roof of the stations allows for natural lighting, creating a comfortable environment for commuters while promoting energy efficiency.
