“…This factor ranked fourth for minimising cost overrun. This result agrees with the findings of previous studies [13]. The importance of this factor lies in its containment: (1) avoiding negative weather effect, (2) accidents, (3) vandalism and (4) damages caused by third parties, (5) compliance with laws and regulations and (6) capability to predict local conditions.…”

“…Several studies from different countries have discussed the conceptualisation of waste in the lean construction philosophy. This conceptualisation is related to the existence of activities without value, including overtime, unnecessary expense of resources or space, unnecessary worker movement, waiting time and rework [11,13,17,[51][52][53][54][55][56][57]. CW is often clustered into physical (materials wastage) and non-physical (time and cost) overruns.…”

“…Several considerations for enhancing CS during IPh have been reported by different researchers. In previous studies [9,[34][35][36][37], 20 factors were identified: (1) scaffolding, (2) ladder access to heights, (3) mobile scaffolds, (4) workplace access, (5) housekeeping, (6) roof work, (7) personal protective equipment, (8) mobile-elevated work platforms, (9) site safety information documents, (10) plan of action, (11) competency of workers and ongoing training, (12) monitoring system, (13) hazard reporting, (14) accident reporting, (15) incidents/near misses, (16) discipline, (17) Health and Safety Authority(HSA) inspections, (18) communication in the workplace, (19) responsibility for safety in the workplace and (20) cooperation. International laws, regulations and specifications have discussed safety requirements in CPs as labour laws [38], such as Occupational Safety and Health Agreement No.…”

Implementation Phase Safety System for Minimising Construction Project Waste

The construction sector is a key component of a nation’s gross domestic product, but its inherent nature results in potentially dangerous conditions that affect the safety of all workers on construction projects (CPs). Therefore, the original idea of the research is to determine the relationship between safety system (SS) during the implementation phase (IPh) of CPs and the minimisation of waste (materials, time and cost). Achieving a lean construction work requires suitable planning, safety considerations and waste resource minimisation throughout the project cycle. This research aims to identify and rank the safety factors during the IPh of a CP, which will have positive effects on minimising waste. Information and data were gathered from the existing literature and the structured interviews and questionnaire survey conducted among 111 randomly selected construction companies. Questionnaire results were evaluated using statistical tools, such as hypothesis testing, analysis of variance and linear regression. This research identified and ranked 24 important safety factors with positive effects on minimising waste in CPs during IPh. The seven most important safety factors that should be considered to minimise material, time and cost wastage are as follows: handling, management, external factors, workers, procurement, site condition and appropriate scaffolding for SS. The best linear model was developed on the basis of the importance index of the identified factors. This model can predict the minimisation of waste (materials, time and cost) in CPs by using SS. Thus, the safety criteria and SS should be used during IPh to minimise waste on the basis of the developed model.

“…Firm commitment to sustainable construction and environmental management helps reduce material wastage on a project (Adewuyi and Odesola, 2016). Waste reduction increases overall net income and helps achieve economic stability (Husnain et al, 2017). Minimizing and managing waste at construction site saves the cost of disposal and transport, increases profits, saves time, protects the environment, and creates clean and safe work sites (Eze et al, 2016).…”

In Ethiopia, the rapid expansion of the construction sector has resulted in the wastage of construction materials that negatively affect the environment, society, and the economy. The reason is inefficient waste management strategies practiced in construction projects. Hence, an adequate material waste management strategy is required. This study was an attempt to identify the key techniques that can help to minimize material wastage in building construction projects. Questionnaire surveys, interviews, and reviews of previous studies and related literature were employed in gathering the relevant data. Seventy of 85 questionnaires administered and distributed to contractors, consultants, and clients were returned. These data were analyzed using the relative importance index method. The results indicated that employing waste management officers for this purpose, using prefabricated or off-site production of components, appropriate on-site waste management, and incorporating a policy of material waste minimization plan were identified as key measures to minimize construction material wastes.

“…It is also known as the best contributor to the economic development of any country. On average it contributes 5% -15% in GDP of a country, [1] which is a significant input. [2 & 3] highlights this sector as one of the highest resource consuming sector needs a considerable amount of resources concerning monetary and non-monetary capitals.…”

The construction sector is responsible for providing fundamental physical structure required for living and survival of human life. Increased development works have led in resulting the massive amount of waste generation in developing countries. Due to poor management system on sites, it has become more crucial and exerts several negative impacts on society and the environment. This Unused waste material has a negative impact on the ecosystem and needs a considerable amount of money for recycling, reusing and disposal of the waste. Like other developing countries Pakistan is spending a significant portion of its GDP on handling construction waste. Among the several other factors, the key contributes are highlighted in this study. This study is exploratory work investigating the types of construction waste generated on site and their relative impact of the project cost in construction projects of Pakistan. Through questionnaire the opinion of clients, consultant and constructor have been taken to identify the major types of waste having more impacts on cost and time. Through Average index, severity index and importance index, the probability of occurrence of waste through different materials, severity level of waste production by these materials, and the overall effect of all waste generating materials have been found respectively. Among the materials sand, concrete, tile is the most common materials, which are responsible for a waste generation while time and cost are the two most common non-physical waste generating factors.
