The correct selection of methods and techniques for planning construction projects represents one of the key initial steps for their successful implementation. In the planning of construction projects and the management of their execution, methods for critical path calculation are often chosen. Although they provide certain important information about the project itself and assist project managers in their daily activities, they are not suitable for visualizing linear engineering structures such as roads or highways, where one dimension is significantly more prominent than the other two. Therefore, the aim of this paper is to highlight the importance of correctly selecting planning methods according to the type of structure, as well as the importance of properly combining different planning methods. This will be demonstrated through the example of a road construction project, specifically a section of the third road in Opatija, 2 km in length, using a combination of two linear planning methods: a Gantt chart and an orthogonal plan. The results obtained emphasize the importance of correctly selecting methods and techniques for planning construction projects based on the type of structure, as well as the potential for combining different linear methods to obtain key information for effective management during their execution.
