Identifying the causes of delay in industrial factory construction: A case study in Binh Duong, Vietnam

Abstract

This study analyzes the causes of delays that often occur during the construction of a factory in Binh Duong province, Vietnam. To determine the level of delay, the study used a progress analysis method based on the main tasks, comparing the planned progress with the actual progress. The window analysis method to find out the causes of delays for each case that causes the main delay is also presented. Numerical results, based on the situation of a factory project, show the main causes of delays such as: construction permits, pile work, structural work, finishing work, mechanical and electrical system work, and fire protection completion certificate. The results also show that 04 contents leading to frequent delays of the above causes are lack of workers (52 days of delay), lack of equipment (47 days of delay) and materials delivered late by the contractor (128 days of delay), and subcontractors late in the construction process (180 days of delay). In total, these four frequent causes delayed the project by 407 days. The study provides results that can assist managers of similar factory construction have a basis to adjust the process to reduce delays in the construction process.
