The Effect Of Music On Construction Labor Productivity, Ayush Khare
Construction Management
Every day the construction industry is looking for ways to improve labor productivity, jobsite morale, and overall project efficiency. Contractors often focus on larger strategies such as scheduling, manpower planning, equipment selection, and material coordination to help projects stay on time and within budget. However, smaller jobsite conditions can also affect how workers perform throughout the day. Music is one of these conditions. On many construction sites, music is already used informally by laborers while they complete physical and repetitive tasks. Even though music is common in construction culture, its effect on productivity and morale is not often measured or …

From Ports To Projects: Estimating The Impact Of Supply Chain Volatility And Trade Policy Changes On Construction Material Prices, Ahmed Shiha, Islam H. El-Adaway
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Construction material markets are often reliant on imported commodities. Import tariffs and temporary trade barriers disrupt supply chains, presenting stakeholders with uncertainties regarding how such disruption impacts construction material prices. Despite the plethora of research efforts that examine the effects of economic conditions on construction material prices, the impacts of the import quantities remain understudied. This paper fills this knowledge gap using a multistep methodology. First, the prices of major construction materials and the quantities of the relevant imported commodities are retrieved. Second, the stability of their historical trends was assessed using econometrics-based tests. Third, a nonlinear autoregressive distributed lag …
