Scie-Ed building

The university is transforming its campus with state-of-the-art infrastructure development. We are creating spaces that foster learning, empower groundbreaking research, and offer an enriching university experience.

UFS Sasol Library

The UFS has been hard at work to move away from traditional library spaces towards creating tech-enhanced, flexible environments that are dynamic for teaching and learning. According to Jeannet Molopyane, Director of Library and Information Services, they strive to align their spaces with global best practices with the infrastructure changes.

Centre for Mineral Biogeochemistry

The Centre for Mineral Biogeochemistry – completed in February 2023 – integrates seamlessly with its surrounding environment, while also providing a new collaborative workspace for the centre’s personnel. This state-of-the-art facility boasts various laboratories which were mainly funded by the Department of Science and Innovation (DSI). The CMBG includes, among other initiatives, the Mineral Node of the Biogeochemistry Research Infrastructure Platform (BIOGRIP), an initiative of the DSI. This space is situated next to the existing Microbiology Building on the Bloemfontein Campus. 

University Estates Building

For this repair and renovation project, with a construction theme, internal and external materials were selected for their low-maintenance qualities. The first office, located opposite the entrance door, features cladding with exposed galvanised corrugated iron. A new steel mezzanine level was installed and painted in ‘CAT’ yellow and black. All pipes, including plumbing and electrical, are exposed on wall surfaces. The use of internal exposed brickwork, concrete floors, and oriented strand board in ceilings and cupboards further accents this quality in the completed project. 

Animal Research Centre

The Animal Research Centre on the Qwaqwa Campus, replaced the temporary structure that previously served as animal housing. The new structure complies with the requirements and standards for a research facility and caters to the needs of researchers and animals, including small and large rodents. The exterior materials used complement those of the surrounding buildings, providing a low-maintenance profile. The building, accessible to persons with disabilities, contains two research laboratories, an ecotoxicology laboratory, a veterinarian’s office, and a procedure room.

South Campus 24/7 Study Space

The shift to extended programmes and dramatic increase in student enrolment on the South Campus created the need for additional study areas. Considering the steep site outcrop and the existing pedestrian routes from the lower campus, the design explored building blocks that progressively staggered up the hill to accommodate a small amphitheatre study area, maximising seating capacity. This allows the building to accommodate the site’s steepness rather than ignore it. The final design provides study spaces on three levels, all accessible via a ramp, with the main functions situated on the primary level. This design also ensures accessibility for all users, including those with disabilities.

KovsieGear

Incline Architects has designed a new innovative space on the Thakaneng Bridge on the Bloemfontein Campus to accommodate the expansion of the KovsieGear outlet. This new design incorporates extra retail space along with additional room for administration work. The KovsieGear shop now features a new aesthetic, created with natural materials to complement the UFS colours.

Research helps farmers save with irrigation

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
