“…In addition, a perceived loss of productivity in performing night work exists in transportation-related construction and maintenance operations (Hancher and Taylor 2001). Mostafavi et al (2012) confirmed that decreased productivity, which in turn affected construction cost and schedule, was a considerable concern in nighttime operations.…”

“…To name but a few they include safety issues (Hinze and Carlisle 1990;Arditi et al 2007); lighting/illumination (ElRayes and Hyari 2005; Gambatese and Rajendran 2012); nighttime work selection/decision supports (Park et al 2002;Douglas and Park 2003;Al-Kaisy and Nassar 2009); costs (Ellis and Kumar 1993;Minchin et al 2013); and productivity (Ellis and Kumar 1993;Mostafavi et al 2012).…”

“…Project participants would plan their projects better if differences (if any) in productivity between daytime and nighttime operations are comprehensively understood. If the estimation of construction productivity does not incorporate the effects of nighttime factors, such estimate will fail to provide reliable information for planning purposes (Mostafavi et al 2012). This paper attempts to respond to that need in sewer construction in Vietnam.…”

“…Literature provided little information as to the labor efficiency associated with working a second shift (Hanna et al 2008). Mostafavi et al (2012) proposed a methodology to quantify the impact of qualitative nighttime factors on the productivity of asphalt paving operations. In this study, the authors adopted qualitative factor worth (QFW) proposed by Zayed and Halpin (2004) to calculate the effects and the productivity index (PI) of the nighttime asphalt paving operation.…”

“…Although many studies have addressed the nighttime operations of highway construction, no significant research has addressed those of sewer construction, especially with regard to productivity. In addition, most of the previous studies focused on the assessment of productivity in both labor-and equipment-extensive projects only for daytime operations (Mostafavi et al 2012).…”

Sewer construction in urban areas often has significant impacts on work zone traffic control, traffic flow, and safety. Contractors typically introduce night shifts to meet contract schedule and to reduce traffic congestion. However, there is a lack of understanding of how shift work is associated with labor productivity in sewer construction. This research investigated labor productivity of ten major activities in sewer and drainage construction in Ho Chi Minh City, Vietnam when these activities were performed in both day and night shifts. Levene's tests and t-tests were employed to analyze the data and investigate the research hypothesis. Results revealed that four activities were significantly sensitive to shift work and the other six activities were not. Pavement cutting and timber piling activities had higher productivity in day shifts. In contrast, steel sheet piling and manhole concreting were more productive in night shifts. Labor productivity of excavation, formwork installation, rebar fabrication/installation, pipe installation, sand filling, and asphalt pavement was not significantly different between the two shifts. The results were verified by the experienced site managers/engineers through structured interviews. The findings form this paper help contractors effectively manage their sewer projects by allocating resources appropriately to construction activities between the day and night shifts.
