“…Tam et al ( 2005) also considered the FWS selection criteria identified by Hanna (1989), excluding the cost criteria. However, this criterion can be an important criterion in the selection process since FWS is a major cost item in RC construction (Ko et al 2011;Krawczyńska-Piechna 2017). Type of structural slab, type of lateral loads supporting system, uniformity of building, and logistical support from formwork supplier Type of structural slab, type of lateral loads supporting system, uniformity of building, and logistical support from formwork supplier were identified in 15 out of 26 studies reviewed.…”

Formwork system (FWS) is one of the key components in reinforced concrete (RC) construction. Therefore, selection of the most appropriate FWS plays a critical role in the project success. Since the FWS selection is affected by several compromising and conflicting criteria, numerous studies have been carried out to identify the FWS selection criteria and/or have employed various multi-criteria decision-making (MCDM) methods since the early 1990s. However, there is no research that conducts a critical review of the previous studies addressing the FWS selection criteria in building construction projects. This study aims to fill this knowledge gap. For this purpose, a critical review of the relevant literature was carried out using an integrative approach and the findings were validated through face-to-face interviews with professionals specialized in formwork engineering. The findings of this study may provide practitioners with a useful guide that can assist them in selecting the most appropriate FWS.

“…The planning process is run with the interaction of the planner, who controls the planning attempts, defines constraints (i.e., on resources) and decides on the final solution. A similar simulation approach to works planning was presented in Reference [31], where an interactive simulation was applied to plan concrete works and formwork utilization.…”

This article presents an interactive method of computer-aided assembly planning. It is estimated that such planning will be more and more desirable due to the increasing use of prefabrication in construction. Prefabrication meets the trends of sustainable development and digitization as it enables the application of intelligent control systems at the stage of highly specialized production, assembly and facility maintenance. The presented planning method is based on the Monte Carlo simulations and logical algorithms for assembly work planning. It was determined on the basis of the literature studied and our own observations. The paper introduces a detailed model of assembly works planning and is an example of using a computer application developed on the basis of the described model. The example confirms the correctness of the algorithm and indicates its usefulness in the scope of analyzing many decision variants. Further research on labor productivity rates for assembly works, implementation of digital databases of assembly machines and prefabricated elements, as well as integration of the proposed application with the BIM environment should make it easier to commercialize the developed application.

“…If we assume that the resources in the number x i,j will participate in the performance of the task z throughout the entire time t(z), then some of them (due to the effi ciency mismatch) will be just partially used. This underutilization of resources should be minimized through the cost of loss (Marcinkowski, 2007(Marcinkowski, , 2015Marzantowicz, 2016;Krawczyńska--Piechna, 2017). However, without knowing the distribution of resources' involvement into task z completion, let us determine x i,j by minimizing the cost of their work, assuming that all resources involved into task performance work the entire time t(z):…”

“…The issue can be solved during project scheduling, using variant allocations of available means of work and verifying workloads with the machine work effi ciency factor -e i,j (1). Of course, in each organizational variant, the unit cost of working resources (machines) should be made real, and in additional, the analysis of the cost of losses due to resources underutilization should also be carried out -as in Marcinkowski (2015) and Krawczyńska-Piechna (2017). The planning analyses in cost estimation applications (here Norma PRO) and scheduling ones (here MS Project) should be conducted according to the following methodology:…”

The article presents ways to search for the optimal composition of an assembly of machines/set of resources to perform a set of construction processes on separate work fronts, distinguishing the technological order of their execution and without distinguishing the technological order of execution. The method of approach to the problem is subordinated to the scheduling technique using cost estimates, in particular data on material inputs for the performance of work processes and unit costs of these outlays. In the optimization models, the cost and time criteria were used, providing fl exibility in the formulation of preferences by the planner.
