Project Title: LTA DE112 – Pedestrian Overhead Bridge and Commuter Infrastructure Enhancement
Scope of Work
Our project encompasses the comprehensive design, submission, and construction of a new covered pedestrian overhead bridge (POB) featuring both steel and reinforced concrete (RC) components. The elements include a lift shaft, covered staircase, covered ramp, linkway to an existing bus shelter, creation of a new bus shelter, water tank layby for N park, installation of double impact guardrails, and anti-climb railings at the center divider. The project also involves intricate electric and lightning protection works.
1. Balestier Road:
- Transportation of a 200-ton precast POB from the Tuas precast yard to Balestier using our modular trailer with turntable configuration.
- Launching of the POB using a 500-ton mobile crane Liebherr LTM1500-8.1 and a 1000-ton mobile crane Terex AC1000.
- Overcoming space constraints with a meticulous engineering study, considering the limited 2-lane dual carriageway available for crane parking.
2. Clementi Ave 4:
- Erection of a temporary steel overhead bridge from the existing MRT train station to a residential area for future development.
- Transportation of bridge segments, divided into three major parts, from the fabrication yard to the site using Goldhofer modular trailers with police escort on three separate nights.
- Launching each bridge segment separately during the night using our 500-ton mobile crane Liebherr LTM1500-8.1.
- Careful study and planning to navigate through the site’s obstacles, including trees and lamp posts, ensuring precision during the lifting operations.
Challenges and Solutions:
Our team navigated challenges such as constrained spaces and site obstacles by conducting thorough engineering studies, ensuring that lifting operations were executed with precision. The professional execution of oversized cargo transportation, provision of mobile cranes, and lifting expertise underscores our commitment to the successful realization of LTA DE112.
This project showcases our dedication to excellence in planning, engineering, and execution of complex infrastructure projects, contributing to the enhancement of pedestrian mobility and commuter infrastructure in the specified locations.
