Abstract
The competitive market realities in industrial environments demand timely completion of construction projects making time conservation a major concern for both owners and contractors. And the unpredictability of a construction project often leads to disputes followed by litigations between owners and contractors. Schedule compression is a common practice to achieve this timely completion of projects, however, can have detrimental consequences in terms of labor productivity and subsequent cost increase. Loss of productivity, however, is difficult to quantify especially when stemming from compressed schedule. Numerous researchers and trade associations have developed productivity factors to quantify the impact of schedule compression on labor productivity, but there has not been a method to quantitatively determine whether the project was impacted by schedule compression or not. This paper introduces a logistic regression impact model by analyzing the quantitative definition of schedule compression. The model will enable the user to determine if the schedule compression resulted in productivity loss or not. Based on the analysis of eight different factors, the logistic model will allow contractors and owners to determine the probability of a project being impacted by schedule compression.
