The construction industry is highly competitive for skilled labor and materials. Labor shortages may become more acute as the supply chain adjusts to uneven industry growth. Additionally, the cost of certain building materials, especially lumber, steel, concrete, copper, and petroleum-based materials, is influenced by changes in local and global commodity prices. Increased costs or shortages of skilled labor and/or materials could cause increases in construction costs and / or construction delays. We may not be able to pass on increases in construction costs to customers. Sustained increases in construction costs may, over time, erode our margins, and pricing competition may restrict our ability to pass on any such additional costs, thereby decreasing our margins.
