SWOT ANALYSIS IN PROJECT MANAGEMENT FOR SLOPE REINFORCEMENT USING THE GEOCELL METHOD

Abstract

Slope stabilization is an important aspect of construction projects to ensure safety, execution efficiency, and long-term structural performance. This study aims to compare several slope reinforcement methods—namely geocell, hydroseeding, grass block, and shotcrete—based on time efficiency, cost effectiveness, and quality/safety performance, as well as to evaluate the geocell method using SWOT analysis and Weighted SWOT Analysis. The comparative results indicate that each slope reinforcement method has distinct characteristics; therefore, the selection should be aligned with project priorities. Based on the analysis, the geocell method provides the best and most balanced combination of cost, time, and quality among the alternatives. This method offers the lowest cost, a relatively efficient construction duration, and a sufficiently high level of quality and safety, although it does not always achieve the highest absolute performance. The SWOT analysis reveals that the main strengths of the geocell method lie in its economic advantage, flexibility for application under various slope conditions, and its significant ability to reduce erosion. However, its weaknesses include a relatively longer installation duration and the need for skilled labor, as the system performance is highly dependent on installation quality. The results of the Weighted SWOT Analysis yield an Internal Factor Score (IFS) of +1.38 and an External Factor Score (EFS) of +0.38, placing the geocell method in Quadrant I (Aggressive Strategy). This position indicates that strong internal capabilities support the optimal utilization of external opportunities. Therefore, the geocell method is considered highly feasible and is recommended as an effective, economical, and competitive slope stabilization solution compared to hydroseeding, grass block, and shotcrete methods in construction projects.
