“…The third factor that MCs consider when choosing an appropriate level of design responsibility to sub-contract is the level of experience of the SC. Literature states that SCs may have a wealth of knowledge about the design process and the product itself (Franz et al, 2013;Gil et al, 2001;Lee et al, 2009;Makkinga et al, 2018;Shafaat et al, 2014). This could be knowledge that the MC does not possess.…”

“…The knowledge and experience that the SC brings to the project can lead to faster and better design decisions. The mechanism behind this is that the experience of the SC simplifies complex decisions to routine (Shafaat et al, 2014). This ensures that the SC can make appropriate decisions in the design stage without spending much time on that decision.…”

“…Many studies therefore address SC selection and focus on the criteria (and their relative weights) that contractors implicitly or explicitly use to select their SCs (Abbasianjahromi et al, 2013;Hartmann and Caerteling, 2010;Hartmann et al, 2009;Kumaraswamy and Matthews, 2000;Ramalingam, 2020;Ulubeyli and Kazaz, 2016;Ulubeyli et al, 2010). Other studies focus on the resources of SCs, or the relationship between MC and SC (Aagaard et al, 2015;Elazouni and Metwally, 2000;Gil et al, 2001;Shafaat et al, 2014;Tan et al, 2017;Yik et al, 2006).…”

PurposeIn the construction industry, an under researched area of study is how main contractor (MC) sub-contract design responsibilities to sub-contractor (SC). This lack of knowledge is particularly serious in the context of delivery methods such as design and construct where design responsibilities are pushed down the supply chain. In this study, it is aimed to explore which level of design responsibility MCs sub-contract to SCs, for what reasons, and what the impact of sub-contracting decisions is on projects.Design/methodology/approachA qualitative in-depth multiple case study was conducted. Six sub-contracting cases were examined in two civil engineering projects. In each project, the MCs sub-contracted pre-fabricated beams, reinforcement and railing to SCs. Data collection included document analysis and interviews. A within-case and cross-case analysis was conducted to examine emerging empirical patterns. These patterns were used to elaborate theory and develop propositions.FindingsMCs sub-contracted design responsibilities to SCs as suggested by literature. However, despite that sub-contracting was in keeping with literature, several problems were reported in the cases where MCs involved SCs no earlier than in the construction stage. This is not to be expected according to theory.Originality/valueThis study adds value to the sub-contracting field as it provides new insights in relationships between the level of design responsibilities sub-contracted and the impact of that on projects. The study also revealed new factors such as building information modelling (BIM) interoperability that should get more attention in sub-contracting.

“…dams, power plants), many conflicts arise between the CTFLP and the TRP (Cheng and O'Connor 1996). Resolving these conflicts is crucial for satisfactory CTFLP and the motivations are summarized as follows: First, much research has indicated that specialty subcontractors were quite common and important in construction projects and resolving the conflicts between the general contractor and each specialty subcontractor is critical for their decisions (Elazouni and Metwally 2000;Arditi and Chotibhongs 2005;Shafaat et al 2014). Second, many cooperations between the general contractor and the subcontractor in large-scale construction projects failed since the conflicts between the CTFLP and the TRP were not resolved.…”

“…In this context, a conflict is defined as any action or circumstance resulting from incompatible or opposing needs (Peña-Mora et al 2003). If the conflicts are not resolved, the adversarial relationships will jeopardize potential or ongoing collaborative construction operations (Elazouni and Metwally 2000;Humphreys et al 2003;Shafaat et al 2014;Arditi and Chotibhongs 2005). Moreover, the Ministry of Housing and Urban-Rural Development has reported serious accidents in China since the conflicts between the general contractor and the subcontractors were not resolved.…”

The construction temporary facilities layout planning (CTFLP) is important and complex in large-scale construction projects. During the CTFLP process, the general contractor has conflicts with many subcontractors regarding other pre-planning tasks, such as the transport routes planning (TRP). The resolution of the conflicts is crucial and this study attempts to determine the CTFLP considering conflicts resolution. Specifically, a novel methodology based on conflicts resolution between the CTFLP and the TRP is proposed, which can be adapted for future CTFLP based on resolving other types of conflicts. The two procedures-based methodology is composed of a bi-level model and a solution approach. The methodology is applied to a dam construction project in China to test the applicability, and the results show that it is able to obtain a satisfactory CTFLP and prevents some crucial conflicts, thus, promoting construction operations and making a significant contribution to the practice of construction projects.
