Quem Raises Glass Prices Amid Construction Cost Surge

Quem, a leading construction materials supplier in South Africa, has raised glass prices by 18% this month, intensifying pressure on an already strained construction sector. The increase comes as the country grapples with a broader cost-of-living crisis, with inflation reaching 7.4% in April 2024, according to the South African Reserve Bank. The move has sparked concerns among developers and homeowners, with many fearing further delays in housing projects and infrastructure development.

Construction Costs Spiral as Glass Prices Surge

The rise in glass prices follows a series of supply chain disruptions and increased energy costs, which have hit the manufacturing sector hard. Quem, based in Johannesburg, cited rising energy tariffs and raw material shortages as the primary reasons for the price hike. The company’s spokesperson, Thandiwe Mkhize, stated that the increase was “necessary to maintain production quality and meet international standards.”

Construction industry analysts say the price surge is exacerbating existing challenges. “Glass is a critical component in both residential and commercial projects,” said Sipho Dlamini, a project manager at BuildRight, a Johannesburg-based construction firm. “When costs go up, developers are forced to delay projects or pass the burden to consumers.”

The impact is particularly felt in the affordable housing sector, where cost overruns have already stalled several initiatives. The Department of Human Settlements reported that 3.2 million households remain without adequate housing, highlighting the urgency of keeping construction costs manageable.

Labour Costs Outpace Material Increases

While glass prices have surged, the biggest burden on construction projects remains the rising cost of labour. According to the National Union of Mineworkers, wages in the construction sector have increased by 12% year-on-year, outpacing inflation. This has placed additional strain on developers, many of whom are already struggling to meet the targets set by the National Development Plan 2030.

“Labour costs are the real crisis,” said Dr. Noma Mokoena, an economist at the University of Cape Town. “Even if material prices stabilise, the cost of skilled workers is making it harder to deliver on housing and infrastructure goals.”

Labour unions have called for a review of wage structures, arguing that current rates do not reflect the cost of living in major cities like Durban and Pretoria. “We’re not against fair wages, but we need a balance,” said union leader Mpho Nkosi. “Otherwise, we risk derailing the country’s development agenda.”

Government Response and Future Outlook

The Department of Trade, Industry, and Competition has announced plans to review construction input costs, with a focus on stabilising material and labour prices. A task force, including representatives from Quem and the National Union of Mineworkers, will meet in early June to propose solutions.

Meanwhile, the private sector is exploring alternative materials to reduce dependency on expensive glass. Some developers are turning to locally sourced alternatives, such as polycarbonate panels, which are cheaper but still face supply challenges.

With the construction sector playing a key role in achieving the African Union’s Agenda 2063 goals, including improved infrastructure and housing, the current cost pressures pose a significant risk. The government’s ability to manage these challenges will be critical in determining the pace of African development.

What to Watch Next

The coming months will be crucial for the construction sector. A decision on the government’s task force recommendations is expected by July, and industry stakeholders are closely monitoring the outcome. Additionally, the National Development Plan 2030’s mid-term review, scheduled for 2025, will provide a key benchmark for progress.

For homeowners and developers, the immediate challenge is finding ways to manage rising costs without compromising project quality. As the sector navigates these pressures, the broader implications for South Africa’s development goals will become increasingly clear.
