Material and Labor Cost Volatility: Fluctuations in the price of key construction materials (e.g., asphalt, concrete, steel, fuel) and increases in labor costs or shortages of skilled labor can significantly impact project profitability and margins, particularly on fixed-price contracts.

Reliance on Public Infrastructure Spending: A substantial portion of STRL's revenue is derived from publicly funded infrastructure projects. Changes in government spending priorities, budget allocations, or economic downturns affecting public finances could reduce project opportunities and revenue.

Intense Competition and Bid Margins: The heavy civil construction market is highly competitive, leading to pressure on bid prices and profit margins. Aggressive bidding by competitors could result in winning fewer profitable contracts or accepting projects with lower returns.
