It is necessary to identify critical success factors (CSFs) that affect the construction process. This paper’s aim is to define the CSFs considering views of all construction project stakeholders. The contribution of this paper is to categorize project success factors into categories and quantify the effect of each category taking into account the effect of all stakeholders on project efficiency and progress. To achieve this objective, a comprehensive literature review was carried out. After literature review, 40 success factors were compiled into seven categories: project-related factors, company- and work-related factors, client-related factors, project management factors, design-team-related factors, contractor-related factors, project-manager-related factors. Consequently, a survey including these listed success factors was prepared and distributed to various experts in the construction field to be ranked; 148 responses were received. Employing the Relative Importance Index (RII) and traditional Analytic Hierarchy Process (AHP) method with Saaty random index that prioritizes these CSFs, the collected data were analyzed after receiving responses. Even though there were disagreements in stakeholders’ views and their goals, significant areas have been identified as project financial issues, managerial aspects, and authorities’ approval mechanism. The outcome of this paper would be used by construction industry professionals to support, evaluate, and measure the success of projects for better allocation of resources.

“…Thus, there will be situations where a fully compensatory or a non-compensatory approach may be required, and also, situations where an intermediate kind of approach would be more suitable, and which would, therefore, require a "quasi-compensatory" one. The approach presented in Section 3 was tested in the construction of the brewery where the problem arose for which a hypothetical-deductive research method validated similarly as in Polat (2016) and Abbasianjahromi, Rajaie, Shakeri, and Kazemi (2016), based on the validity of the assumption of the study.…”

Sorting Subcontractors’ Activities in Construction Projects With a Novel Additive-Veto Sorting Approach

Selection processes in civil engineering infrastructure projects might require more time and effort than the decisionmakers involved in these projects are normally prepared to devote to running them. A novel approach is proposed to sort these activities into classes that represent their impact on the project, namely additive-veto sorting model, which should be considered before any bidding procedure. Therefore, problems regarding the client’s satisfaction caused by subcontractors can be avoided, and the decision-makers involved in the selection problem can devote to each class an effort compatible with the impact that activity might have on the project. The novelty of this method is that it was built to reflect the quasi-compensatory rationality of decision-makers in the construction industry; it provides them with insights on subcontractors’ activities, and it is grounded on and inspired by a real case study. The new parameters proposed within this model introduce the idea of vetoing an activity being assigned to a class when this activity is incompatible with the decision-maker’s preferences. By using this novel method, the authors succeeded in finding results that avoided a complete compensation amongst the factors considered, taking into account ranges that would be of significant importance in the decision process.

“…Moreover, clients are further exacerbating these challenges with their ever intensified demands for higher quality, faster schedules and lower costs (Abbasianjahromi et al 2016). To overcome these major challenges, projects within the AECO sector must be delivered differently (Chinowsky and Songer 2011) using innovative and digital advanced technologies such as BIM (Gruszka et al 2017;Hosseini et al 2016;Hosseini et al 2018b;Mitchell et al 2012).…”

Integrating BIM in Higher Education Programs: Barriers and Remedial Solutions in Australia

et al. 2021

Despite the increasingly widespread adoption of Building Information Modelling (BIM) in Australia, a steady pipeline of BIM-ready graduates needed to meet industry demand remains elusive. Anecdotal evidence suggests that universities in Australia have not been successful in delivering BIM-enabled graduates of the right calibre due to a plethora of barriers. This paper aims to identify, define and delineate barriers to integrating BIM education into programs in Australian higher education institutions (HEIs), and unearth the antecedents of these barriers. A post-positivist philosophical design was implemented to undertake a cross sectional and mixed methods approach to collecting and analysing primary data. Data was collected through qualitative methods-18 structured and seven semi-structured interviewswith key BIM educators in Australia. Data were analysed using Nvivo. Findings reveal that four thematic groups of barriers hinder effective BIM education integration in Australian HEIs. These are: 1) change management challenges; 2) curriculum and content limitation; 3) educators' problems; and 4) disconnect with the industry. The research concludes that a major overhaul is needed to change the modus operandi via which the industry, accreditation bodies and government policy makers engage with HEIs to define BIM education programs. However, given a notable dearth of investment and collaboration from the industry and government, HEIs cannot manage the change needed for running effective BIM training programs. Therefore, cross government/industry collaboration and financial support is needed to stimulate a cultural shift in existing HEIs' provisions to generate future generations of highly skilled and competent BIM enabled graduates. This paper represents the first attempt to contextualise HEIs' capacity to deliver advanced BIM training given a wider and prevailing economic and political topology that currently fails to adequately support the supply of fully trained graduates.
