Jurong Innovation District Underground Monitoring
GEOUE presents a preliminary monitoring discussion for Jurong Innovation District’s underground logistics network, covering excavation, ground movement, groundwater, structures, interfaces and long-term performance.
Jurong Innovation District · Singapore
Singapore’s first district-scale underground freight network is already moving from concept into operation.
Master Plan 2025 identifies Jurong Innovation District as a key advanced-manufacturing node in Singapore’s West Region. JTC’s District Logistics Network places heavy freight movement underground so that the surface can support safer streets, business activity, greenery and an 11 km Sky Corridor.
Phase 1 is operational
JTC states that Phase 1 of the underground District Logistics Network is already operational. A later JTC update records Phase 1 as completed in January 2025, with Phase 2 targeted for completion in 2029.
3 km of underground freight paths
JTC’s published material describes the Bulim network as spanning about 70 ha with about 3 km of underground paths dedicated to freight logistics, designed for heavy vehicles and future automated goods vehicles.
Underground freight, surface roads, elevated mobility
JID combines underground goods movement with surface transport and an 11 km Sky Corridor for walking, cycling and future autonomous passenger movement. That creates multiple structural and operational interfaces within the same district.

Ground & Geological Context
JID spans a large area, so the ground model must be precinct-specific.
Publicly available JTC information does not provide one final borehole profile for the whole District Logistics Network. GEOUE therefore separates confirmed local information from regional geological context and avoids assigning one formation to every part of JID.
Boon Lay, Jalan Besar and Pandan formations occur within the study area
JTC’s 2025 EIA for CleanTech Park and Bahar reports that much of Site A is underlain by the Boon Lay Formation, comprising sandstone with subordinate interbedded mudstone, pyroclastic and volcaniclastic rocks. Jalan Besar Formation superficial deposits and Pandan Formation limestone are also mapped within parts of the study area.
Jurong Formation materials can vary substantially
LTA’s current civil-design guidance notes that rocks within the Jurong Formation can exhibit wide variation in strength and weathering, including sandstone, siltstone, shale, conglomerate, mudstone and limestone. This reinforces the need for project-specific SI rather than a single simplified “Jurong soil” assumption.
- Confirm weathered-rock and soil profile at each underground structure
- Identify groundwater regime and any perched or local water-bearing zones
- Map existing foundations, utilities and buried assets before excavation
- Define stable reference zones for inclinometers and settlement monitoring
- Separate construction movement from normal industrial loading effects
- Coordinate monitoring access with operating factories and logistics routes

District Interfaces
The monitoring challenge grows where underground logistics meets an operating industrial district.
Bulim Square interface
JTC states that Bulim Square connects directly to the underground DLN and has AGV-ready cargo lifts extending the logistics chain to tenant units. Monitoring around these interfaces should distinguish building movement from local tunnel or basement response.
Road & utility interface
Future underground works can interact with roads, drains, sewers and utilities. JTC’s current CleanTech Park and Bahar programme separately includes major land-preparation and infrastructure works, reinforcing the need for cross-package coordination.
Jurong Region Line interface
LTA confirms that JRL construction is underway and that JID will be served by three MRT stations. Where future DLN or district works fall within a railway influence zone, monitoring must reflect the applicable rail-protection and project requirements.
Sky Corridor interface
The 11 km elevated Sky Corridor creates a separate structural layer above ground. Foundations, piers, roads and underground assets can all share limited corridors and need clearly separated monitoring responsibilities.
Operating factories
JTC describes JID as an active advanced-manufacturing ecosystem. Excavation, vibration, access restrictions and monitoring installations must therefore be planned around business continuity rather than assuming a greenfield site.
Ecology & land preparation
JTC’s current EIA work in CleanTech Park and Bahar shows that future district expansion also has biodiversity and earth-control constraints. Monitoring access and temporary works may need to coexist with environmental mitigation measures.

Monitoring Risks & Pain Points
Movement is only useful when the project can tell what caused it.
Excavation-induced movement
Cut-and-cover, basement or other underground works can cause wall movement, settlement and heave. The actual construction method for each future package should determine the instrument layout and reading frequency.
Groundwater change
Dewatering, temporary works or permanent drainage can alter groundwater. Settlement trends should therefore be reviewed together with piezometric and construction information rather than in isolation.
Adjacent industrial assets
Factories may contain heavy machinery, precision equipment, production lines and vibration-sensitive spaces. Baseline movement and vibration need to be established before nearby works make attribution difficult.
Road and pavement performance
Underground routes may pass beneath or beside roads and logistics areas. Surface settlement, local distortion and buried-asset movement can become operational issues even when the underground structure itself remains serviceable.
Multiple simultaneous contracts
JTC has publicly described numerous adjacent building and infrastructure projects in JID as an interface and coordination challenge. Monitoring data can become fragmented when each package uses different naming, survey control and reporting conventions.
Operations after construction
Phase 1 is already operational. Monitoring for future extensions should therefore consider not only construction safety, but also how the existing logistics network, interfaces and access routes remain available during expansion.
Candidate Instrumentation
A practical JID system would combine ground, groundwater, structures and asset protection.
The following instruments are candidate methods for preliminary discussion only. They are not presented as JTC’s issued DLN instrumentation specification. Final selection must follow the actual construction method, SI, adjacent assets, contractual monitoring requirements and responsible engineer’s criteria.
| Engineering question | Candidate methods | Potential use | Main design consideration |
|---|---|---|---|
| How is retained ground moving? | Manual inclinometer, in-place inclinometer | Lateral ground or retaining-system deformation with depth | Reference zone, casing depth, construction sequence, required latency |
| Is groundwater changing? | VW piezometers, standpipes | Groundwater or pore-pressure response during excavation and dewatering | Hydraulic response, installation zone, baseline duration, dewatering records |
| Is the surface settling? | Precise levelling, settlement markers, ATS + prisms | Roads, pavements, structures and sensitive assets | Stable reference, sight lines, traffic access and independent verification |
| Is subsurface settlement developing? | Rod / magnetic extensometers, deep settlement points | Layer-specific vertical deformation where subsurface movement matters | Anchor depths must follow the actual ground profile |
| How is the underground structure responding? | Convergence points, prisms, tilt sensors, strain gauges | Structural deformation during construction or selected operational stages | Temperature, structural details, installation protection and inspection access |
| Are adjacent buildings affected? | Prisms, settlement markers, tiltmeters, crack meters | Building movement and distortion around excavation or underground works | Baseline condition, asset sensitivity, access and response responsibility |
| Is construction vibration affecting operations? | Vibration monitors | Factories, laboratories, equipment and occupied facilities | Project-specific criteria, instrument mounting and operational background vibration |
| Are roads / utilities moving? | Levelling, survey prisms, utility-specific sensors where justified | Pavement and buried-asset protection | Utility-owner access, reference stability and construction zone of influence |

Instrument Choice
Automation should follow risk and access—not become the default for every point.
| Parameter | Option A | Option B | JID decision logic |
|---|---|---|---|
| Lateral movement | Manual inclinometer | In-place inclinometer | Manual profiles can be efficient for scheduled checks; IPIs suit selected critical depths or stages where higher-frequency trends justify automation. |
| Groundwater | Standpipe | VW piezometer | Standpipes offer simple groundwater observations; VW sensors support automated local pressure data where excavation response needs shorter latency. |
| Surface movement | Precise levelling | ATS + prisms | Levelling provides robust campaign measurements; ATS can increase frequency where sight lines and stable references are available. |
| Building behaviour | Manual survey + condition records | Automated prisms / tilt sensors | Automation can follow active risk periods while manual methods remain useful for independent verification and assets with lower required frequency. |
| Tunnel / structure response | Survey convergence | Local strain / displacement sensing | Survey tracks global geometry; local sensors can resolve structural response at selected details when the design requires it. |
| Data access | Manual readout | Fixed automated / distributed access | The acquisition model should follow response time, power, communications, access windows and the consequence of delayed data. |
Monitoring Strategy
Design the monitoring sequence around the workfront and zone of influence.
1. Pre-construction baseline
2. Enabling works and excavation
3. Underground structure construction
4. Interface works to buildings, roads and logistics facilities
5. Commissioning and operational baseline
6. Expansion beside an operating network
Data, QA/QC & Digital Integration
JID is already a digital district. Monitoring data should fit that operating model.
JTC states that JID has district-wide 5G and supports IoT, digital twins, analytics and AI applications. JTC has also described plans for its Open Digital Platform to be implemented at JID. For geotechnical monitoring, this creates an opportunity—but only if engineering traceability remains intact.
Asset identity
Keep each instrument tied to a stable physical location, project tag, serial number, installation record and responsible work package.
Reference control
Maintain survey datums and groundwater references consistently so different contractors do not create false movement through incompatible baselines.
Construction context
Store excavation levels, dewatering stages, support installation, nearby works and other events with the monitoring timeline.
Instrument health
Flag calibration changes, drift, damaged points, communications faults, replacements and data gaps before the information reaches a dashboard.

Official Reference Cases
Underground projects elsewhere show the value of mixed instrumentation and traceable handover.
The projects below are independent public references, not GEOUE projects and not direct design analogues for JID. They are used to illustrate transferable principles in underground monitoring, asset protection and data management.
Singapore experience with major underground industrial infrastructure
JTC’s Jurong Rock Caverns is a large underground industrial facility beneath Banyan Basin. JTC presents it as an example of creating industrial capacity underground while saving surface land.
Transferable lesson: underground infrastructure can be an operational industrial asset, so construction monitoring and long-term inspection need to be considered as one lifecycle rather than separate worlds.

Surface, subsurface and structural monitoring used together
Crossrail’s official Learning Legacy documents rod extensometers, in-place inclinometers, multi-level vibrating-wire piezometers, precise levelling and automated survey systems used to understand tunnelling-induced ground and asset response.
Transferable lesson: different instruments should be paired around the mechanism, and monitoring intensity can change as the active construction zone approaches and passes an asset.
Official source: Crossrail Learning Legacy — Field Instrumentation
Monitoring needs a controlled end state
Crossrail’s published close-out datasets show formal monitoring reports and sensor decommissioning records, including consideration of when influencing construction had ended before sensors were removed.
Transferable lesson: sensor removal should be an engineering decision supported by construction history and movement trends, not simply the date a contractor demobilises.

Underground freight is becoming a wider urban-planning question
The UK Government’s Future of the Subsurface report reviews underground freight transport as a future infrastructure model and highlights coordination, regulation, digital mapping and monitoring as recurring subsurface challenges.
Transferable lesson: underground logistics is not only a civil structure; it is a long-term spatial, operational and data-management system.
