Building Construction Labour Productivity in Arid Climate Environment

Abstract

Productivity is a significant aspect of construction industry that plays vital role for success and failure of any construction project. This industry generates 11% to 13% of GDP all around the globe and the cost of labour in any building project is 20% to 35% of the cost of Building. On daily basis labour utilizes 30% of time on productive activities rest 70% of the time is ruined in non-productive activities, there are multi factors which are affecting the labour production in construction industry hence this study provides an overview of productivity, Total Factor productivity, method used to measure accurate productivity in construction projects. The objective of this study is find out percentage up to what extent labour production is affected due to weather conditions, however this study is carried out in arid climate region in Month of June 2018, where minimum temperature was recorded 26.0 Celsius degree at 7:30 AM and Maximum was 47.80 Celsius degree at 3:00 PM. A descriptive survey research design approach was adopted using continuous observation method of study. Project work study manual served as the research instrument to collect the data on selected building sites for 30 working days. Data collected were analyzed using descriptive statics. The results show that average monthly production of mason gang was recorded with less production of 28.759%, Carpentry gang with average monthly loss of production 16.74% & steel fixer gang had average monthly loss of production was 12.188. This concludes that prior to signing the contract for construction project. The location, environment, topography of region, capacity of construction operatives must be kept in mind to decide the proper timeline for the successful of project.

Productivity monitoring in building construction projects: a systematic review

“…Table 1 shows a summary of co-occurred keywords with the total link strength between the keywords. Among the different construction activities, masonry (Arif and Khan, 2020; Bhatti et al , 2019; Chui et al , 2012; Florez and Cortissoz, 2017; Joshua and Varghese, 2011; Mao et al , 2018; Ouga et al , 2020) and formwork (Azhar et al , 2020; Bhatti et al , 2019; El-Gohary et al , 2017; Golnaraghi et al , 2019; Lee et al , 2017; Mine et al , 2015) were presented lonely or combined with other activities, the most activities monitored for their productivity.…”

“…Although traditional methods have some limitations for site monitoring, such as time-consuming, operose, missing or incomplete information, resulting in a slow flow of information, make effective decision-making difficult, labor-intensive and high expenses (Kimoto et al , 2005; Luo et al , 2018; Naoum, 2015; Omar et al , 2018; Yang et al , 2015), they have been used in several studies to monitor the productivity of different indoor activities (such as tiling, plastering, masonry work, false ceiling boarding and fixing and application of screed) and outdoor activities (such as formwork, reinforcement steel activities, MEP, concrete work and curtain wall) (Alchaer and Issa, 2020; Azhar et al , 2020; Bhatti et al , 2019; Chui et al , 2012; Florez and Cortissoz, 2017; Gouett et al , 2011; Hwang, 2010; Ko and Han, 2015; Kubečková and Smugala, 2020; Mao et al , 2018; Mine et al , 2015; Ouga et al , 2020).…”

Construction Tradespeople Perception of the Factors Motivating Labour Productivity on Construction Projects

“…In an emerging economy like Nigeria, Usman et al (2012) accentuate that the continue project failure being experienced in the industry are associated with poor contractors performances resulting from poor workmanship, high level of rework, low output, delay completion and cost overruns, high accident records and poor productivity of labour. Bhatti et al (2019) carried out study aim at determining the extent to which changes in arid climate environment affect variations in labour productivity. The study concluded that the higher the temperature, the lower the productivity of labour.…”
