Enhancing Sustainable Construction through Innovative Prefabrication Solution – The Spiral Connector System – Housing Development Board
For more than four decades, HDB has played a key role in leading the nation’s sustainable development agenda. HDB has planned and developed homes that are affordable and sustainable, and has perpetuated a cohesive community. Being the largest developer in Singapore, HDB recognises its role in promoting environmental sustainability in its development projects.
The objectives pertaining to construction in support of sustainable development are to increase buildability, improve productivity, reduce material wastage and ensure safety in construction works. HDB has over the years developed and implemented its own fully prefabrication building system. Towards the late 90’s, the use of precast concrete was also extended to critical structural concrete elements such as columns, beams and lift shafts.
The Spiral Connector system was developed as a safe, reliable, cost effective connection system for splicing precast components. It embraces the theory of ‘concrete confinement and shear action’ to generate the required strength for connecting reinforcement bars efficiently. The connector system has undergone rigorous tests to meet the high performance standards. Unique in its design, it was also patented in countries such as Singapore, China and India.
As we build taller homes, prefabrication helps to achieve quality, speed and resource conservation for public housing development. In promoting sustainable construction, this innovation helps bring the construction of HDB’s ‘Green Homes’ to the next level of excellence.

 

Design of a Passive Irrigation System for Landscaped areas under Flyovers – National Parks Board

The National Parks Board (NParks) manages a sizeable number of landscaped areas under flyovers as part of Singapore’s green infrastructure network. In such areas, irrigation systems and supplemental watering through the deployment of water tankers are used to deliver water required for plant growth.

These systems are typically costly to install and maintain, and consume energy to run. To increase cost effectiveness of its landscape operations and develop more environmental sustainability practices, NParks studied alternatives to current systems. This led to the development of a novel, passive sub-irrigation system that confers several advantages over the current systems.

These include removing the need for external energy input by relying on natural forces like gravity and capillary action, achieving closer match between water supply and plants’ water needs, and concealment of the irrigation system to provide greater landscaping flexibility.

 

FAMS : An intelligent fish activity monitoring technology to ensure water quality – Institute for Infocomm Research (I2R) & PUB Singapore’s National Water Agency

The A*STAR Institute for Infocomm Research (I2R) and PUB are jointly pioneering an innovative water quality monitoring technology known as the Fish Activity Monitoring System (FAMS).

One of the ways PUB ensures water quality is by manually monitoring live fish kept in tanks (all around the island) for any sudden decline in their population. This is an indication of possible decline in water quality. The developed FAMS in this project has enabled automatic central monitoring of fish activities and triggering of alerts to the operators.

When there is any sudden dip in the number of live fishes or fishes show signs of distress, visual and audio alerts will be triggered. This project has contributed to enhancing the security of drinking water in Singapore.

 

Nanostructured Microsphere Photocatalyst for Membrane Fouling Control and Water Quality Improvement: A Pilot Plant Start-Up at Choa Chu Kang Waterworks Singapore – NTU & Stanford University & PUB Singapore’s National Water Agency

For the first time in the world, an engineering system using TiO2 nanostructured microspheric photocatalyst has been successfully applied for membrane fouling control and water quality improvement at Choa Chu Kang Waterworks Singapore.

This pilot-plant project is a two-year collaboration between the NTU, Stanford University and PUB. The Enterprise Challenge, an initiative under the Prime Minister’s Office (Singapore), supported the $2,000,000 pilot project by providing S$ 1,000,000 in matching funds.

This home grown photocatalyst technology is able to remove foulants like natural organic matter, bacteria and trace organics which contribute to the fouling of membranes and poor water quality, thereby reducing water treatment costs and improving water quality. The photocatalyst can also be regenerated for reuse.

 

SuperneTTM Integrated Communication System ST2800 – ST Electronics (Info-Comm Systems)
SuperneT Integrated Communication System ST2800 (also know as ICS ST2800), is an award-winning, field-proven integrated communication solution for emergency services, public safety and mission critical command and control organisation. The system was also awarded with 4 International patents.
 
Launched since year 2004 by ST Electronics (Info-Comm Systems), ICS ST2800 provides the innovative gateway for disparate communication systems to be interconnected and interoperate seamlessly.
 
ICS ST2800 is a great success in terms of the benefits and capabilities it has provided to users who deployed it in their environment. As the world increasingly adopts VoIP-based communication as the standard, there will be a similar growing demand for ICS ST2800 type of solutions. As such, ST Electronics (InfoComm Systems) will continue to devote resources to establish itself as a key player in the area of integrated communication solutions.
