Operations New Era (ONE) -Transforming the Maintenance of State Land and Properties in Singapore

Singapore Land Authority (SLA) manages about 7,700ha of state land, 150 vacant state buildings and 10 offshore islands. Given the scale of work, which is exacerbated by declining manpower, SLA urgently needs to augment current operations with technology and its ONE digital ecosystem (ONE) does just that. ONE is a ground-up initiative to leverage drones, machine learning, geospatial technology, applications, etc. for a synergistic and holistic management of vacant state land and buildings.

Innovation Summary

Innovation Overview

SLA engages contractors to carry out routine maintenance works, such as pest control, housekeeping, grass-cutting, and other activities. Management of contractors to ensure delivery of quality maintenance services and traditional physical inspections by officers can be time-consuming and labour-intensive, especially on the offshore islands. There may also be site constraints and safety considerations, which limit the ability of our officers to conduct inspections in a comprehensive manner. ONE transforms the current manual and manpower intensive maintenance regime to one that harnesses technology for greater productivity, effectiveness and quality.

Real Time Awareness

Using ONE, instead of physical inspections, officers can manage contractors remotely in real time as they will be alerted to view contractor’s coverage and have the option to view the contractor “live” via the CCTV app. Upon works completion, a report can be retrieved instantly (Annex A).

In the management of offshore islands, officers use ONE to monitor utilities levels remotely (Annex B) instead of traveling to the various islands to sight water and diesel tanks levels. SLA also completed a trial on the offshore islands where a self-charging drone will fly automatically based on pre-determined schedule and flight paths without the need of a pilot to physically sight the drone flight on the ground (BVLOS flight). Using machine learning algorithm, potential maintenance issues can be automatically picked out for officers to follow up in real time (Annex C). While SLA is looking to implement technology on the offshore islands, poor wireless internet connectivity is currently hampering technology implementation. To enable usage of technology on the offshore island, SLA is currently testing the use of TV White Space (TVWS) technology for stable wireless connectivity.

Rapid response on the go

With ONE, officers are able to receive and respond to public feedback rapidly. At the same time, ONE helps officers make better decisions on the go as officer can easily retrieve key geospatial information, tools and best practice guides at the click of a button. Officers are also able to create reports of their inspections in a fuss-free, yet comprehensive manner that can be immediately sent to the relevant contractor for immediate follow-up (Annex D).

Preventive Maintenance

Detailed inspections for preventive State Building maintenance (e.g. former schools, hospitals, etc) are labour intensive and requires machineries such as boom lifts to access hard-to-reach areas.
ONE uses drones, machine learning algorithm and 3D photogrammetry where potential maintenance will be automatically flagged out in 3D models for follow up. This method is safer and helps to resolve potential maintenance issues at its infancy so that they do not snowball into issues of greater concerns (Annex E).

The ONE Masterplan (Annex F) details the upcoming plans for the system where SLA will transit into Artificial Intelligence (AI)-led predictive maintenance regime, and eventually to an era where robotics and automation will handle routine maintenance tasks such as grasscutting, housekeeping, etc.
