Severity of Causative Factors to Construction Waste Generation: Iraq Construction Industry

Construction waste generation has been perceived as a crucial issue that has critical consequences on the project effectiveness and ecological effect of the construction industry. The key objective of the current research is to identify the root causes of material construction waste generation in Malaysia. A well-structured questionnaire was designed based on the 52 identified root causes of material waste generation. The developed questionnaire was distributed to 35 highly experienced in Malaysian construction industry experts. The collected data was analyzed by the use of mean score analysis. The top identified root causes are poor supervision during the construction stage, lack of efficient site management, last minute changes, cutting uneconomical sizes of materials, and constant design changes during the construction period. The initial findings will aid construction practitioners to focus on these root causes in order to reduce the material construction waste generation at construction sites.

Frame Work

Construction waste generation and handling issues have been in focus to achieve sustainable goals. Considering the growth of construction in India, it is appropriate to link generation of construction waste with the growth. It measures to minimize and handle the construction waste are not developed and efficiently adopted, then it may threat for environment. In this research study, Residential construction case studies have been referred to identify the quantum of waste and source of wastage on the projects. Based on the identification of major waste generation on site, how the mitigative steps has been taken that also included in the form of frame work for minimization of waste on the site.

Construction Procedure

The construction sector is among the fastest growing sectors in Malaysia; it consumes a vast amount of natural resources and produces a massive volume of construction and demolition waste. The waste is collected in a decentralised manner by sub-contracted companies. It is challenging to obtain reliable information on the amount of construction waste generated, because it is hard to determine its exact quantity and composition. Therefore, this study proposes a quantitative construction waste estimation model for residential buildings according to available data collected from the Construction Industry Development Board, Malaysia. In the development of this model, a theoretical investigation of the construction procedure and the construction waste generation process was conducted. The waste generated rate was determined as 25.79 kg m−2 for new residential constructions, which translates into about 553,406 t of anticipated waste annually.

The construction industry faces many challenges with problems related to construction waste as it takes up time and effort without adding value to clients. A concept in project management, namely lean construction, has the main focus of minimizing waste and providing added value to a construction project. The purpose of this study was to know the existence of non-physical waste, its causative factors, and how lean construction can be implemented to minimize non-physical waste in earthworks, foundations and basement 2 of the Sanggala Hotel and Office Building Project. The study was carried out by observation, document study, and questionnaires to identify non-physical waste. This study showed that the non-physical waste that most often occurs in related project was equipment breakdown frequently with a weight of 0.086. Meanwhile, the non-physical waste variable that has the greatest impact on causing time overrun on the project was delayed schedule with a weight of 0.080. Equipment breakdown frequently is influenced dominantly by the equipment shortage. Delayed schedule is influenced dominantly by licensing problems. In general, lean construction approaches such as Construction Meetings, Preventive And Predictive Maintenance, and Fail-Safe For Quality And Safety can be applied by contractors to minimize non-physical waste that was dominant in the project.

Contractual Obligations

Construction industry creates a massive amount of waste, which typically ends up in landfills. Canadian construction industry represents 30% of the total municipal solid waste deposited in landfills. Construction and demolition (C&D) waste has created negative socioeconomic and environmental impacts including contaminating ground water, emitting greenhouse gases, and adding more waste to scarce landfills. Literature is cited rework/waste generation due to ambiguity/errors in construction contract documents. Exculpatory clauses in contract documents are included in contractual agreements to prevent contractor claims, which often cause rework. After an extensive contract documents review, these clauses were categorized in to eight major areas. This paper (1) analyses expert opinions on pre-identified contractual clauses; and (2) introduces recommendations to minimize rework and waste in construction projects. It was found that the clauses related to quality, workmanship, and field quality control/inspection have the most potential to generate construction waste.

Using Data

This study examines construction waste generation and management in Taiwan. We verify the factors probable affecting the output of construction wastes by using data for the output of declared construction wastes produced from demolition projects in Taiwan in the last year, expert interviews, and research achievements in the past, and find “ on-site separation” is the factor with effects on the output of construction wastes via cross-correlation by algorithms such as K-Means and Decision Tree C5.0. It can be seen that the output (0.092(t/M3) with on-site separation or 0.329(t/M3) without on-site separation is highly correlated with the composition ratio of construction wastes and referred to as a valid conclusion.
