EFFECTS OF CONSTRUCTION COST AND VOLUME ON CONSTRUCTION TIME OF EDUCATIONAL PROJECTS IN TEXAS
- View All
Studies indicate that there is a relationship between project cost and construction time for different construction markets. The purpose of this study is to validate the time-cost relationship model developed by Bromilow et al.1 in context with educational construction projects in Texas. The model was extended to include the magnitude of the projects in terms of gross floor area and project delivery methods to determine whether these variables also have an effect on project duration. Data related to 39 educational projects was obtained for the study. SPSS program was for analysis of the data. The statistical technique used for the analysis was stepwise linear regression. The results indicate that when gross floor area is also used an independent variable, construction cost does not have any relationship with construction time for educational projects in Texas. However, the results show a statistically significant relationship between construction time and magnitude of the project, measured by gross floor area, at the level of significance (p-value) of < 0.0001. A prediction model of construction time has been developed based on the results of the study. This model will be useful to students taking courses related to cost estimating and construction project scheduling and also to professionals involved with construction industry. 2012 American Society for Engineering Education.
