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.

UFS boasts with most advanced chemical research apparatus in Africa 

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie.  The NMR is used to analyse molecular structures. 

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa.  The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research.  We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard.  Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around.  I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million.  With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level.  Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes. 
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.  
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry.  These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples. 

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
