PurposeLegal remedies are incorporated into international construction joint ventures (ICJVs) to mitigate contractual breaches. The effectiveness of remedies is predicated on two conditions; the comprehensiveness of the contract and its enforceability within the jurisdiction of interpretation. Relational-related weaknesses contribute to contracting parties placing a premium on the contract's capacity for mediating the relationship. However, contracts are not always enforceable. This study aims to examine means by which joint venture relational governance can be maintained under conditions of minimal legal recourse.Design/methodology/approachA relational contracting (RC) theory was used as the theoretical underpinning of the paper. Data were collected and analyzed following a multiple-case study approach from case projects in which ICJVs' was used.FindingsThe findings reveal (1) 17 relational and contractual governance problems; the main six being contractual flexibility, contractual joint venture system, contract reviewing, project conflict, national culture and leader–follower transgressions; (2) relational and contractual governance problems are managed differently, depending on financing sources and partners' national culture; and (3) that a developed RC-based framework comprising four stages is able to facilitate relational and contractual governance in ICJVs.Originality/valueThis study is novel in providing a guided approach to developing non-legal remedies for the mitigation of contractual breaches in ICJVs, grounded in theory and contextualized for the construction sector.

PurposePublic–private partnerships (PPPs) are notoriously prone to disputes among stakeholders, some of which may unduly jeopardize contract performance. Contract disputes arising in Iran are often due to inefficiency of PPP concession agreements and practice. This study presents a causal-predictive model of the root causes and preventive measures for inter-organization disputes to enhance the likelihood of achieving desirable performance in PPP projects.Design/methodology/approachA theoretical “causal-predictive” model was developed with fourteen hypotheses based on extant literature and contractual agency theory, which resulted in the creation of a pool of 110 published items. Data were obtained from a questionnaire survey with 75 valid responses, completed by 4 stratified groups of Iranian PPP experts. Partial least square structural equation modeling (PLS-SEM) was used for validating the proposed model via a case study.FindingsResults reveal that the main three factors of PPP desirable performance are as follows: on-time project completion, high quality of activities/products and services for public satisfaction. Further, the most influential factors of the lifecycle problems, construction stage, and preferred risk allocation included risk misallocation, improper payment mechanism and failure to facilitate a timely approval process.Originality/valueFor researchers, the findings contribute to the theory of contractual agency; specifically, how different influences among the model's elements lead to better PPP performance. In practical terms, proposed outcome-based strategies will inform PPP stakeholders to avoid dispute occurrence and thus improve the time, quality and services of projects.
