Abstract
This research aims to study and utilize software for the design and cost estimation of roadworks by using Blender for 3D modeling and Road Price for cost estimation. A case study was conducted on a road improvement project from the Yala Provincial Office of Public Works and Town & Country Planning. The findings revealed that the percentage difference between the construction cost estimated using the software and the conventional calculation method was 1.36%. This indicates that the software provides cost estimates that closely align with the actual construction costs. Moreover, revisions can be made and recalculated more conveniently and quickly, reducing the working time by 69.57%. The development of integrated design and cost estimation software minimizes errors and enables users to select or change materials in cases where project costs exceed the set budget. It also enhances the effectiveness of data presentation. The satisfaction level of practitioners increased from an average score of 3.04 (moderate level) to 4.16 (high level), an increase of 1.12 points or 36.84%.
