Summary
This study developed a statistical model to predict construction waste in high-rise buildings. The model identifies design and production systems as key factors influencing waste generation, offering insights for mitigation strategies.
Area of Science:
- Environmental Science
- Civil Engineering
- Construction Management
Background:
- Construction waste is a significant environmental concern.
- Accurate quantification of waste generation is crucial for effective mitigation strategies.
- Predicting construction waste is challenging due to material diversity and project variability.
Purpose of the Study:
- To propose a statistical model for determining waste generation in high-rise building construction.
- To assess the influence of design processes and production systems on construction waste.
- To provide a tool for better waste management in the construction industry.
Main Methods:
- A statistical model was developed using multiple regression analysis.
- A case study was conducted using data from eighteen residential high-rise buildings.
- The model identified dependent (waste generated) and independent variables (design, production system).
Main Results:
- The best regression model achieved an adjusted R-squared value of 0.694.
- The model predicts approximately 69% of the factors influencing waste generation in similar constructions.
- Individual independent variables had low determination coefficients, highlighting the importance of their combined influence.
Conclusions:
- The developed statistical model effectively quantifies construction waste in high-rise buildings.
- Design and production systems are major contributors to construction waste generation.
- The model underscores the necessity of evaluating the joint impact of various factors on waste generation for improved construction waste management.

4.4K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

9.1K
Regression analysis is a statistical tool that describes a mathematical relationship between a dependent variable and one or more independent variables.
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:
