The objective of this research is to determine the critical path of a house construction project. The uncertain duration of activities is set to be the trapezoidal fuzzy numbers. The calculation of the fuzzy critical path has three steps, which are the calculation of the forward pass to determine the earliest start time, the calculation of the backward pass to determine the latest start time and the calculation of the total float pass. The results show that the activities on the fuzzy critical path are the land preparation, construction layout, stake drilling, foundation works, concrete foundation pouring of the basement, roof structure, the second floor construction, ladder structure, concrete foundation pouring of the second floor, wall plastering, tile and wood flooring and landscape decoration.
