The commercial construction market in South Carolina has stabilized through the first half of 2026 after several years of volatility in materials pricing and subcontractor availability. Steel prices have moderated, concrete aggregate supply is stable in the Florence market, and most subcontractor categories are quoting competitive lead times again. For commercial owners who have been waiting to start projects, the current environment is more predictable than it has been since 2021. Delta Building Systems is actively quoting new work for Q3 and Q4 starts and can provide current pricing for most project types within two weeks of receiving scope information.
