Service fees in the category of construction design and system works increased, particularly for structural engineering, reports the Bangkok Post.
Mr Vichai said the price of most construction materials had increased, especially steel and steel products, jumping by 35% year-on-year.
The price increase was mainly a result of the Russia-Ukraine war, which pushed up the prices of energy and construction materials, he said.
Russia and Ukraine are both major steel suppliers, accounting for a combined 14% of the global steel export market.
Russia is the world’s third largest steel product exporter, while Ukraine is the eighth largest.
The Russian invasion has resulted in a steel shortage in the global market.
