COVID-19 Impact

Market Growth Restrained by Pandemic Due to Postponed Infrastructure Projects

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

Budgetary constraints and safety concerns stemming from the pandemic prompted many tunnel construction and maintenance projects to be delayed or cancelled indefinitely. As governments and industries grappled with economic uncertainties and shifted priorities to address immediate health and safety needs, investments in infrastructure were often deprioritized. Consequently, the demand for tunnel inspection robots experienced a downturn as the projects they were intended to support were put on hold. This slowdown in construction activity not only affected the deployment of new robots but also hindered the servicing and maintenance requirements of existing units.
