This paper aims to synthesise the latest literature on supply chain operations of offsite manufacturing in the construction industry to identify and evaluate the uncertainties at each stage of the offsite construction supply chain (OSC-SC) to compile contributions to knowledge and thereby determine the future research directions to improve supply chain resilience (SCR).

The study was conducted as a systematic literature review. In total, 99 peer-reviewed journal papers published between 2015 and mid-2022 were shortlisted and analysed through the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

The bibliometric analysis revealed that the research focusing on supply chain issues and developing best practices in offsite construction adopt case study approaches to investigate the research problems comprehensively. The content analysis revealed the lack of up-to-date knowledge in the construction workforce regarding OSC; low preparedness for the changes brought by the SC uncertainties; the lack of a proper procurement model for OSC; lack of end-to-end visibility of the supply chain to identify uncertainties and lack of national or government standards on OSC-SC, as some of the key problems instigating the identified the uncertainties.

This study clarifies the current knowledge by systematically presenting uncertainties at each stage of the OSC-SC. Moreover, it provides a framework and proposes that future research should focus specifically on individual/team, organisational, supply chain/network and sector/national/supranational levels to improve SCR.

A green lease incorporates sustainability practices to reduce a building’s negative impact on the environment. Facilities managers play an important role in ensuring these best practices are implemented during the operational stage of a building; however, green leasing is an under-researched area in the emerging field of sustainable facilities management (SFM). This paper aims to investigate the common barriers encountered in ensuring environmental performance when a green lease agreement is in operation between a landlord and tenant.

This research was conducted in three stages using the principal-agent problem as the theoretical foundation for data collection. Stages 1 and 2 used semi-structured interviews to collect data with policy/corporate-level professionals, landlord and facilities management representatives who have considerable experience in green leases. Stage 3 used document reviews based on summative content analysis to further evaluate the extent of the contextual use of green leasing concepts as used within the facilities management community.

The study confirmed a strong incentive gap and information asymmetry between the landlord and facilities manager, forming a typical double principal-agent problem when the split incentives between the landlord and tenants are also taken into consideration, which results in agents acting on their own self-interest rather than the interests of the principal. Goal alignment is found to be key for the successful operation and management of a building throughout its life; when present, these goal conflicts can lead to disharmony between the parties to the contract.

The study proposes a few practical measures to close the gaps in incentive and information asymmetry that create the principal-agent problem, while providing recommendations to the facilities management professional community. These recommendations could be included in future revisions of the SFM guidelines or code of practices used by the industry. Although this study exposed a rather neglected area of the facilities manager’s role in green leases, the findings are limited by the relatively small sample size used for the interviews.

This study contributes to the SFM body of knowledge from a green lease perspective, and the theoretical framework in the double principal-agent problem introduced in the study could be used in future research endeavours.

Offsite construction (OC) is an efficient method to reduce waste in the construction industry from a circular economy perspective. Yet, its uptake is subdued by the ambiguities around its supply chain. Hence, the purpose of this study is twofold: to identify the OC project delivery models, the limitations in their procurement approach to facilitate the resilience of the supply chain and interventions to promote supply chain resilience (SCR) and to identify the gaps in the existing procurement process and propose further research areas that implement strategies to improve SCR.

The study was conducted as a systematic literature review. In total, 41 peer-reviewed research papers published between 2013 and 2023 were shortlisted through the preferred reporting items for systematic reviews and meta-analysis guidelines. A descriptive analysis was conducted, followed by a thematic analysis.

The descriptive analysis reveals that the emphasis on digitising OC has shifted to transforming the business model, procurement and supply chain with a human-centric view. In thematic analysis, the predictability of the SC partners and the probabilities of evaluating the prospects are revealed as arbitrary characteristics in the current procurement strategies. Rewarding collaborative relationships among SC partners and incorporating provisions to postpone the module delivery are some interventions to promote flexibility. Drafting comprehensive and effective contracts that address transparency issues and facilitating the need for continuous development of capabilities through procurement are among the further research avenues proposed.

This study is a precursor demonstrating the potential of the procurement process to implement the decrees of SCR for better goal congruence of the OC supply chain.
