Purpose The purpose of this paper is to develop a novel analytical approach for workface planning practice in industrial-construction sector such that the construction work package (CWP) resource budget can be sufficiently planned for delivering possible field installation work package (FIWP) schedules with work uncertainty. Design/methodology/approach The relationship between CWP resource budget and FIWP schedules is first elucidated based on workface planning practice. The literature of work packaging, workface planning and project scheduling is reviewed. A novel analytical approach is then developed to quantify CWP resource budget based on a probability theory, in consideration of the probability of occurrence of feasible FIWP schedules formulated based on a resource scheduling approach. The results of case studies given by the new approach are cross validated by using simulation and optimization techniques. Findings The new analytical approach can assist workface planning by quantifying the expected CWP resource budget to deliver the FIWP work scope with certain activities that are planned at project level and with uncertain activities that are found at workface level. Practical implications The new analytical approach helps project and workface planners to reliably deploy CWP resource budget for delivering FIWP schedules instead of guessing the budget based on experience. An industrial-construction project for upgrading oil-sands refinery facility is used to show the practical implications. Originality/value This research develops a new analytical approach for workface planning practice to determine sufficient CWP resource budget for delivering feasible FIWP schedules with work uncertainty.

“…Results of the DES software identified in this study illustrated the most popular simulation techniques which have been adopted in the construction sector. STROBOSCOPE is a programming language designed for the simulation of processes common to construction engineering (Martinez & Ioannou, 1994), Simphony is unique to provide an environment that supports building simulation environment (AbouRizk et al, 2016), CYCLONE is a construction-oriented simulation technique (Senior & Halpin, 1998), and EZStrobe is a general-purpose simulation program designed for modelling construction operations (Draper & Martinez, 2002). They are the DES software designed for construction processes and have been widely applied.…”

Over the past two decades, discrete event simulation (DES) has been increasingly employed in lean construction research as a response to the requirement of evaluating the impact of the implementation of various lean initiatives. A systematic review of DES application in lean construction research is necessary to examine how DES has been implemented in lean research. This review was conducted by reviewing 49 DES papers published in peer-reviewed journals and IGLC conference between 1997 and 2018, which aims to identify the state of the art development in this specific research area and propose future research directions. The papers are analysed in terms of publications, DES techniques, value of DES, and topic coverage. 13 types of DES techniques, 6 value of DES in lean construction research, and 8 research topics are identified and summarised. The findings of this study are expected to provide useful suggestions for the future research opportunities of DES in lean construction research.

“…To the extent that new and more powerful programming languages and computing tools were developed, the ability to solve increasingly complex problems in construction was also developed. With the introduction and advances in terms of what is known as Special Purpose Simulation Approaches [40], progress was made in the generation of specific simulation environments, seeking to reach professionals of the construction industry with little or no experience in the theory of simulation [41,42].…”

Planning and Scheduling tools used by construction professionals nowadays not always consider the effect of variability in the construction process; they do not consider explicitly the effect of changes in activity durations along the production chain. Discrete event simulation approach is a relevant exception that deserves particular attention from the construction industry. The present research proposes a discrete event simulation model applied to a simplified construction process schedule. This model considered main construction activities divided in: foundations, structure and roofing. The model can be extended and easily applied to other construction activities. Input parameters for the model were obtained directly from on-site field experience and a beta unimodal distribution assigned. On a first stage, PERT scheduling methodology was used for the model, which was later compared with discrete event simulation. Results did not provide evidence of significant statistical differences between different probability distribution used with respect to the mean project duration obtained using PERT scheduling as compared to the discrete event simulation model. This provides conclusions about total project duration and validation of the probability distribution types considered in the present research.
