Upon completion in 2020, the JTC Logistics Hub @ Gul will be Singapore’s first high-rise multi-tenant logistics facility to house container depots, warehouses and a heavy vehicle park—all within a single development.
This will reduce travelling time between logistics nodes, hence improving operational and cost efficiency for the logistics sector.
The eight-storey warehouse facility includes around 30 warehouse units, sized between between 1,700 and 2,500 square metres with flexibility to form larger units, and comes with 128 loading bays.
The inland container depot (ICD)—spread over two levels—will house up to two container depot units, with a maximum capacity of 6,000 TEUs per floor and complete with operational space for container inspection, maintenance and repair services. The facility’s design has been developed for efficiency and safety through the single-directional heavy vehicle traffic flow. The traffic management system, which can be integrated with the automated overhead crane system, helps optimise container flow and communication across multiple parties, such as depot operators, logistics service providers and transportation companies.
The JTC Logistics Hub is one of the first 12 integrated digital delivery (IDD) pilot projects under Singapore’s Construction Industry Transformation Map, with IDD implemented from tender stage and design development to construction and up through facilities management.
The digital technologies include systems for digital ordering/manufacturing, BIM-based digital logistics management, safety management and defect management—all of which contribute towards improved site productivity, reduced site wastage and lower construction risks.
For example, the digital logistics management helps ensure on-time assembly and delivery by allowing the tracking of location and delivery schedules of components, such as large pre-fabricated pieces, from the factory to the final installation site via RFID tags. Special gantries detect when the component departs or arrives at the worksite, and a smart crane automatically determines where the component should be installed. The digital ordering and manufacturing system for materials, such as reinforced bars, cuts down on unnecessary paperwork and improves accuracy and productivity.
Site progress is monitored with aerial drones using photogrammetry, which creates 3D-like images. An omni-directional camera also captures the state of the worksite at various development milestones, allowing people to ‘walk through’ the site virtually.
When a defect is lodged using a mobile device, sub-contractors will be alerted in real-time to rectify it. The defect data will also be updated in a project database for easy viewing and report generating.
All this digital information is accessible to stakeholders located anywhere through cloud-enabled collaboration.
Another notable feature of this project is its innovative structural system. The ICD has 45-metre-high structural columns spaced 16 metres apart. Using conventional steel reinforced concrete columns, with 4-metre-deep floor structural trusses, would require labour-intensive and time-consuming welding work.
As such, the main contractor teamed up with SEN Engineering Group to explore an alternative structural design using form prefabricated steel reinforced concrete (F-PSRC) columns and a thin steel-plate composite (TSC) beam system.
The F-PSRC column is a steel and reinforced concrete composite that uses structural steel angles with batten plates to form a lattice structure. The steel angles replace conventional I-sections, which reduces steel content per metre square, and are designed with bolted connections for faster installation. The integrated formwork also eliminates on-site formwork erection for the concreting process.
The TSC beams are U-beams fabricated from built-up steel plates, which will be filled with concrete in the permanent stage. They range from 0.95 to 2.2 metres in depth—less than the original floor trusses—giving more headroom for MEP provisions. The beams’ surface area also allows for easier fireproofing application.
This project will no doubt be a milestone in the transformation of the local construction and logistics industries, both of which are critical enablers and drivers of the economy.
