A Study on Improving Construction Cost Estimation for Structural Works of Domestic Smart Greenhouses through the Application of Estimating Standards at the Detailed Design Stage
This study evaluated the suitability of construction cost estimation criteria applied at the detailed design stage of smart greenhouse projects and proposed improvements reflecting the structural and construction characteristics of lightweight steel smart greenhouses. The results showed that construction costs varied significantly depending on the estimation criteria because the Standard Estimating System and the Standard Market Unit Price do not adequately reflect the repetitive modular construction characteristics of lightweight steel smart greenhouses. In particular, the total construction cost estimated using the greenhouse-specific estimation standards was approximately 51.7% of that estimated using the Standard Estimating System, indicating a substantial difference between the two estimation criteria and highlighting the need to improve the current construction cost estimation standards. Lightweight steel works consistently accounted for the largest share of the total construction cost 32–33%, while non-structural finishing and cladding works also represented substantial cost components. In contrast, auxiliary steel works showed a relatively higher proportion under the greenhouse-specific estimation standards, highlighting the importance of greenhouse-specific structural members in construction cost estimation. These findings indicate that more appropriate estimation standards are required for smart greenhouse projects. Establishing greenhouse-specific estimation standards, revising labor productivity criteria for repetitive modular construction, developing separate standards for non-structural finishing and cladding works, and subdividing auxiliary steel work items would improve the accuracy and reliability of construction cost estimation.
