The Impact of Labor Shortages in Construction
The construction industry has faced significant challenges in recent years due to labor and material shortages, exacerbated by the COVID-19 pandemic. These shortages have disrupted timelines, increased costs, and strained resources.
The shortage of skilled workers has been particularly acute in New Zealand, with four out of five construction firms citing it as a critical issue. Factors such as border restrictions during the pandemic severely limited the influx of migrant workers, who often fill specialised roles. Even as restrictions eased, many workers moved to industries offering better pay or conditions, further compounding the problem.
These shortages have driven up labor costs and led to project delays, with firms struggling to find qualified staff to meet demand. The effects have been especially pronounced in residential construction, where delays are more common due to the high volume of work.
Material Shortages
Material shortages have created an additional bottleneck. During the pandemic, global supply chain disruptions caused delays in the delivery of essential materials such as plasterboard, timber, and cladding. In some cases, these delays doubled the build time for residential projects, stretching a typical five-month project to over a year.
The increased demand for materials also led to sharp price hikes, with some products, like steel, seeing price increases of 50–60%. Builders often found themselves waiting months for critical supplies, resulting in idle work sites and increased frustration among clients and contractors alike.
To combat these challenges, the construction industry is turning to technology and automation. AI-powered tools can optimise resource planning by accurately predicting labor and material needs based on project data. For example:
- AI can forecast supply chain risks and suggest alternative materials to avoid delays.
- Automated planning tools can reduce the burden on skilled workers, ensuring they focus on high-value tasks.
While these innovations won’t solve all the industry’s challenges, they offer a pathway to greater efficiency and resilience in the face of ongoing disruptions.
