“…Therefore, to effectively monitor the labor work hours and equipment, while simultaneously managing the cost and duration, this study applies a widely used CYCLONE (Cyclic Operation Network) model to simulate the crew productivity of repetitive activities (Agbulos et al, 2006;AbouRizk, 2010;Cho, 2009;Huang et al, 2004;Hong et al, 2011;Sawhney et al, 1998). Before applying the CYCLONE model, productivity is defined and measured in the next section.…”

Cost and duration are two of the most important factors in the successful assessment of a construction project. In order to set appropriate cost and duration targets for individual projects, the targets must first be established based on accurate productivity information from the planning stage. In Korea, the cost and duration of a construction activity are estimated using standardized productivity information provided by the Korean Standard of Estimate (KSE). However, the KSE standardized productivity information may not fully reflect the characteristics of an individual project, given its unique nature. Thus, cost and duration targets set based on the KSE for productivity may be unreasonable and/or unattainable. To address this issue, this paper suggests a simulation-based approach where actual field productivity information is utilized to set more realistic cost and duration targets and to optimize resource allocation, including crew assembly. Specifically, a CYCLONE model is developed for reinforced concrete work that is typically a critical activity in multi-housing projects, which account for 35% of public construction projects in Korea. Experimental application of the simulation model confirmed its promising potential for assisting construction managers in calculating productivity through sensitivity analysis and in planning and controlling efficient resource management.

“…One such prefabricated material is reusable metal formwork, which is cost effective and productive (Huang et al, 2004;Ministry of Federal Affairs Ethiopia, 2003;Richard, 2005). Effective and advanced formwork systems result in successful LHPs in terms of time, cost and quality (Elbeltagi et al, 2011;Lyngcoln, 1991;Swapnali and Kumathekar, n.d.).…”

Huang et al (2004), and Rahim and Haron (2013) ASF is economical, and designed for the speed and efficiency of typical high-rise housing construction (Swapnali and Kumathekar, n.d.). It has the high potential to improve LP in LHPs.…”

Purpose -The purpose of this paper is to establish labour productivity norms (LPNs) on an elemental basis to investigate a measurement for the labour productivity (LP) of aluminium system formwork (ASF) in low-cost housing projects (LHPs) in Sri Lanka.Design / methodology / approach -Case study approach was selected as the most appropriate for the study and semi-structured interviews, document review and direct observations were used for the data collection. Four case studies were conducted. Eight semi-structured interviews were conducted among four cases. Further, document review was used in three cases, and direct observation was

External Insulation Finishing System (EIFS) is recognized as a suitable method for attaining energy efficiency of buildings. However, conventional EIFS is not actively applied to building construction due to additional time and cost compared with interior insulation method. Therefore, as an alternative that can contribute to active utilization of the external insulation system, this study proposes an External Insulated Precast Concrete (PC) Wall System and its simulation for performing productivity analysis. Results of this study are as follows: (1) an external insulated PC-Wall system is developed of which its insulation performance is above 40% higher than that of the conventional EIFS; (2) performance of the developed system satisfied American Standards for Testing of Materials (ASTM) and American Architectural Manufacturers Association (AAMA) standards; (3) applicability of the developed system is verified via test-bed with construction time lapsing about 40 min for each PC-Wall; and (4) CYCLONE modeling methodology is employed to perform productivity analysis of the developed system compared with conventional EIFS.
