SeaLink Highway Conceptual Engineering and Cost Calculation: Workbook, Assumptions, Cost Parameters and Sensitivity Analysis

This dataset contains a documented Microsoft Excel workbook for a conceptual SeaLink Highway engineering and cost model. The workbook includes wind and wave loading calculations, structural and foundation feasibility checks, 1,700 km and 40 km CAPEX estimates, documented input assumptions, documented cost parameters, a data dictionary, quality-control notes, and a one-at-a-time sensitivity analysis. No MATLAB or Python code was used. All calculations and the sensitivity analysis are contained in the Microsoft Excel workbook. The model is intended for conceptual feasibility assessment only and does not represent a construction-ready design, tender estimate, or site-specific engineering assessment.
