- Reducing construction labor costs is difficult because conventional construction is on-site and cannot relocate to cheaper labor markets, unlike manufacturing.
- Prefabrication allows relocation to lower-cost labor areas, but high transportation costs and added capital expenses often offset the savings.
- Using fewer materials is challenging because most structures are already near the material efficiency frontier, and further reductions trade off against higher labor costs or complexity.
- Building codes and risk aversion among architects and engineers limit the adoption of cheaper or alternative materials, despite high margins in some product categories.
- Barriers to lowering material costs include permitting difficulties for new quarries and cement plants, tariffs on foreign steel, and the reluctance to specify unproven products.
- Cheaper finish materials often face aesthetic trade-offs, as lower-cost options feel less solid or are perceived as inferior.
