Analysis Of The Factors That Cause Rework In Construction Work In The City Of Medan

Analysis of the Factors that Cause Rework in Construction Work in the City of Medan

Introduction

Construction work in the field often does not go according to plan. In the process, many deviations can be found, especially at the finishing stage, which requires high accuracy and neatness. This incompatibility leads to the need to do rework or rework, which is caused by the not fulfilling the quality standards set by the company and the rejection of consumers. Factors that can cause rework include design, managerial, and resource factors. Understanding these factors is crucial for construction companies to take strategic steps to improve the quality of work and customer satisfaction, as well as efficiency in the project that is carried out.

Research Background

This study aims to understand and analyze how the design, managerial, and resource factors affect the rework in construction projects. This type of research is descriptive statistical research with associative descriptive nature. Data was collected through the distribution of questionnaires and documentation studies, involving all employees of three construction companies, namely PT. Leprim Globalindo Utama, CV. Bintang Multi Graha, and PT. Citra Anugrah Teknika, totaling 67 people. The research was conducted in the city of Medan, which is one of the major construction hubs in Indonesia. The study's objective is to identify the factors that contribute to rework in construction projects and to provide recommendations for construction companies to minimize rework.

Analysis Method

In data analysis, multiple linear regression methods are used and ANOVA different tests with the help of SPSS 22.0 software. The results of the analysis showed that simultaneously, the design, managerial, and resource factors had a positive and significant influence on rework with the coefficient of determination (R²) of 67.5%. This indicates that the three factors have a significant impact on rework, and that the design factor has a positive but insignificant influence on rework.

Effect of Factors Causing Rework

Design Factor

Design factors that include design errors, design changes, and design obscurity have a positive influence, but insignificant, on rework. This shows that although the design can affect the quality of the work, this factor is not a major cause in the occurrence of rework. Design errors can occur due to various reasons such as lack of experience, inadequate training, or poor communication among team members. Design changes can also lead to rework, especially if the changes are not properly communicated to the construction team. Design obscurity can occur due to unclear or incomplete design specifications, which can lead to misunderstandings and errors during construction.

Managerial Factors

Unlike the design factors, managerial factors such as poor information flow, lack of supervision, and a solid work schedule show a significant positive effect on rework. This indicates that bad management contributes greatly to mistakes and dissatisfaction in construction projects. Poor information flow can lead to misunderstandings and errors, while lack of supervision can result in inadequate quality control. A solid work schedule can also lead to rework, especially if the schedule is not properly planned and executed.

Resource Factor

Human resources also play an important role in the rework process. Incorrect considerations in the field, lack of workers' experience, and inappropriate work procedures have a positive and significant influence on the occurrence of rework. This shows the importance of workers' skills and experience in achieving the desired results. Incorrect considerations in the field can occur due to lack of experience or inadequate training, while lack of workers' experience can result in inadequate quality control. Inappropriate work procedures can also lead to rework, especially if the procedures are not properly planned and executed.

Conclusion

The results showed that despite the influence of the design factor, the biggest contribution to the occurrence of rework actually came from managerial factors and resources. Further different tests show that there is no significant difference in the influence of each factor that causes rework. Therefore, special attention is needed in project management and human resource development to minimize rework in construction work in Medan. By understanding these factors, it is expected that construction companies can take strategic steps to improve the quality of work and customer satisfaction, as well as efficiency in the project that is carried out.

Recommendations

Based on the findings of this study, the following recommendations are made:

1. Improve Project Management: Construction companies should improve their project management practices, including planning, execution, and control. This can be achieved by implementing a robust project management system that includes clear goals, objectives, and timelines.
2. Develop Human Resources: Construction companies should invest in developing their human resources, including training and development programs for workers and supervisors. This can help to improve the skills and experience of workers, leading to better quality control and reduced rework.
3. Implement Quality Control: Construction companies should implement a robust quality control system that includes regular inspections and testing. This can help to identify and correct errors and defects early on, reducing the need for rework.
4. Improve Communication: Construction companies should improve communication among team members, including designers, engineers, and construction workers. This can help to prevent misunderstandings and errors, leading to reduced rework.

By implementing these recommendations, construction companies can minimize rework and improve the quality of their work, leading to increased customer satisfaction and efficiency in their projects.
Frequently Asked Questions (FAQs) about Rework in Construction Work

Q: What is rework in construction work?

A: Rework in construction work refers to the process of redoing or revising work that has already been completed, often due to errors, defects, or changes in design or specifications.

Q: Why is rework a problem in construction work?

A: Rework can be a significant problem in construction work because it can lead to delays, cost overruns, and decreased quality of the final product. It can also cause frustration and dissatisfaction among customers and stakeholders.

Q: What are the common causes of rework in construction work?

A: The common causes of rework in construction work include design errors, managerial factors (such as poor information flow, lack of supervision, and a solid work schedule), and resource factors (such as incorrect considerations in the field, lack of workers' experience, and inappropriate work procedures).

Q: How can construction companies minimize rework?

A: Construction companies can minimize rework by improving project management practices, developing human resources, implementing quality control systems, and improving communication among team members.

Q: What are the benefits of minimizing rework in construction work?

A: The benefits of minimizing rework in construction work include improved quality of the final product, increased customer satisfaction, reduced costs, and improved efficiency in project delivery.

Q: How can construction companies measure the impact of rework on their projects?

A: Construction companies can measure the impact of rework on their projects by tracking metrics such as rework rates, cost of rework, and time spent on rework. They can also conduct regular audits and assessments to identify areas for improvement.

Q: What are some best practices for reducing rework in construction work?

A: Some best practices for reducing rework in construction work include:

• Conducting thorough design reviews and quality control checks
