60-Metre Steel Link Bridge
500-Ton Heavy Crane Deployment
Executive Summary
The Phileo Damansara link bridge required far more than structural steel fabrication. Installing a 60-metre steel bridge between existing buildings demanded precise survey verification, detailed lifting engineering, and meticulous transportation planning within a live urban environment. Sanki coordinated engineering studies, heavy lifting analysis, crane planning, and logistics to minimise installation risks before execution. Through continuous dimensional verification, finite element lifting analysis, and carefully planned launching procedures, the bridge was transported and installed safely while maintaining structural integrity and minimising disruption to surrounding traffic and ongoing operations.
1.0 Continuous Survey and Dimensional Verification
Continuous survey verification ensured the fabricated bridge accurately matched actual site conditions before installation, reducing tolerance issues during the final launch.
As-Built Synchronisation
Regularly updated site measurements, building offsets, floor levels, and connection locations to align fabrication with actual site conditions.
Precision Alignment
Verified bridge connection points, structural levels, and installation clearances to minimise dimensional discrepancies before delivery.
Reduced Installation Risk
Identified potential deviations early, allowing engineering adjustments before launching and reducing the need for site rework.
2.0 Engineering Analysis and Stability Study During Bridge Lifting
Dedicated lifting studies and temporary works engineering ensured the bridge remained stable throughout every stage of the hoisting and launching operation.
Structural Lifting Analysis
Assessed centre of gravity, lifting points, stress distribution, deflection, and temporary loading conditions.
Custom Temporary Works
Engineered lifting hooks, lifting lugs, and temporary strengthening to safely transfer lifting loads.
Real-Time Engineering Control
Engineers monitored crane synchronisation, sling tension, bridge stability, wind conditions, and lifting movements throughout the launch.
3.0 Transportation and Heavy Lifting Planning
Careful logistics planning enabled the oversized bridge to be transported and installed safely through a restricted urban environment with minimal disruption.
Transport Route Planning
Evaluated turning radii, road widths, overhead clearances, utilities, and access restrictions before delivery.
Heavy Crane Engineering
Planned crane positioning, lifting sequence, boom configuration, load sharing, and tandem lifting using 200-, 400-, and 500-ton cranes.
Ground Stability Assessment
Designed temporary crane platforms and verified ground bearing capacity to support safe lifting operations.
4.0 Project Outcome
The successful installation of the Phileo Damansara link bridge demonstrated how engineering coordination, continuous survey verification, lifting analysis, and strategic transportation planning work together to deliver complex urban infrastructure safely and efficiently. By integrating engineering, logistics, and controlled execution, Sanki completed the bridge installation while maintaining structural integrity and minimising disruption to the surrounding environment.
