Prof Kahilu Kajimo-Shakantu believes there are a number of benefits and lessons that the construction industry can draw if they adopt technology that can lead to sustainable construction beyond the COVID-19 era.

The construction business has been hit hard, with various negative impacts on cost, implementation timelines, profits, and others. Increased and smart adoption of technology, however, can transform the sector to make it more sustainable. 

This is the belief of Prof Kahilu Kajimo-Shakantu, Head of the Department of Quantity Surveying and Construction Management at the University of the Free State (UFS).

As president of the Association of Schools of Construction of Southern Africa (ASOCSA), she delivered the welcoming address of the 14th Built Environment conference (21, 22 September 2020). Prof Kajimo-Shakantu is the sixth president of ASOCSA.

The theme of this year’s built-environment conference, presented for the very first time in a virtual format, was Technology, Transformation and Sustainable Construction.

Identify and harness opportunities 

“It is clear that while COVID-19 remains a challenge, opportunities can be identified and harnessed even by our own construction industry through the exploitation of technological, transformative, and sustainable practices. The technology and transformation taking place now – in South Africa and beyond this COVID-19 situation – should be embraced for competitive advantage, even after the pandemic disappears,” said Kajimo-Shakantu.

Clients, consultants, contractors, and suppliers of materials and services can wholly embrace technology and transformation for sustainable, cost-effective, less wasteful, and cleaner construction processes. – Prof Kahilu Kajimo-Shakantu


She also provided some practical suggestions: “Technologies such as remote monitoring of construction sites and selected construction site operations through high-definition cameras and robust software should be encouraged as a way of minimising health and safety risks and mobility costs during the project duration, and at the same time ensuring an all-time virtual presence on site for various purposes.”

“Virtual contract progress meetings, site meetings, and supervision of specialised work are some of the benefits that the construction industry could gain if they adopt technology that can lead to sustainable construction beyond the COVID-19 era,” she added. 

Encourage meaningful partnerships

It is no longer a case of business as usual. Prof Kajimo-Shakantu believes stronger collaboration and meaningful partnerships must be encouraged among all stakeholders if the conference theme is to be fully actualised for the benefit of the construction industry, as it races towards attaining sustainable construction.

She said: “Clients, consultants, contractors, and suppliers of materials and services can wholly embrace technology and transformation for sustainable, cost-effective, less wasteful, and cleaner construction processes.”

Many insightful and thought-provoking papers touching on construction industry challenges and opportunities, as well as the teaching and learning of students, were delivered by both local and international delegates. 

The conference is believed to be one of the major cutting-edge built-environment conferences on the African continent. 

A guest of honour at the event was the Vice-Rector: Academic at the University of the Free State, Dr Engela van Staden. In her welcome address, she challenged delegates to establish a consistent channel for disseminating some of the research outcomes to industry stakeholders, including the respective government departments. “It is time to go beyond building rich databases and prestigious publications for our universities,” she said.

Keynote speakers included Prof Monty Sutrisna, Professor of Construction and Project Management and the Head of the School of Built Environment at Massey University, New Zealand; Prof Obas John, Professor of Sustainability and Environmental Law and Director of Internationalisation at London South Bank University; Prof David Edwards, Professor of Plant and Machinery Management, Birmingham City University, England; and Dr Reza Hosseini, the Associate Head of School (research) in the School of Architecture and Built Environment, Deakin University, Australia.

The various interesting peer-reviewed research papers that were delivered, addressed topical issues that affect the built environment not only in South Africa, but also in the regions beyond.

A research project into low-energy lighting using phosphor materials for light emitting diodes (LEDs) at the Department of Physics at the University of the Free State (UFS) has received further recognition. 

The South African Research Chairs Initiative (SARChi) has awarded further funding for the Research Chair in Solid State Luminescent and Advanced Materials situated in the department. Prof Hendrik Swart, a Senior Research Professor in the Department of Physics, says this means that the Chair will carry on receiving funds from SARChi for another five years. The Initiative also awarded Prof Swart in 2012 for the research, which resulted in funding for equipment and among others, bursaries.    

Better light emission in LED’s
The research focuses on better light emission of phosphor powers in LEDs. It is also looking into improving LED displays in flat screens. The research into solar cells has shown that phosphors can also increase their efficiency by increasing the range of light frequencies, which convert into electricity. It also entails that glow-in-the-dark coatings absorb light during the day and emit it at night. 

Prof Swart says over the next five years the research will focus on developing and producing devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have.” In practical terms, it means they want a farmer’s water pump that works with solar energy to work better with less energy input.” 

Device that simulates sunlight
Prof Swart says the renewal of the Chair’s funding means the department can now get equipment to enhance its research   such as a solar simulator. The solar simulator uses white LEDs whose intensity output and wavelengths can be tuned. The output is measured in number of suns. It enables researchers to work in a laboratory with a device that simulates sunlight.     

According to Prof Swart the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field. 

About 10 postdoctoral researchers are working on the studies done by the Chair in collaboration with the Council for Scientific and Industrial Research. 

The Research Chair Initiative aims to improve the research capacity at public universities to produce high-quality postgraduate students, research and innovative outputs. The criterion for evaluating the department’s Chair includes aspects such as how much development has occurred over the past five years. The assessors look at features such as the number of students the research entity has trained and how many publications the research team has produced.
