Next practice: A trust-and-cooperation “Neighborhood” model for multi-project delivery

This study explores the adoption and effectiveness of a trust and cooperation-based neighborhood model, designed to foster collaboration and reduce friction among stakeholders in operational environments characterized by complex supply chains and multi-stakeholder engagements. Grounded in the psychological theories of reciprocal exchange, the model envisions a ’neighborhood’ where participants collaborate as partners, fostering predictable outcomes, reduced risks, and greater financial stability. Although the model is intended for operational environments requiring intensive trust and coordination, this research tested its application within the construction sector. The work was conducted in two exploratory phases, both in the United States: a concept test survey followed by pressure testing the model through a series of workshops. The concept test survey assessed industry's interest in and compatibility with this neighborhood approach. Results indicated strong support for the model's collaborative approach highlighting its potential to address the issues of mistrust in the industry. The second phase involved a series of codesign workshops with key industry stakeholders, including a project owner, a general contractor, an architect, and several legal experts. These workshops confirmed the model's strengths in promoting cooperation and transparency but also identified challenges, such as the need for better integration with existing legal frameworks and addressing power dynamics within the neighborhood. This study suggests that the trust and cooperation-based neighborhood model has the potential to transform collaboration in other operational environments such as healthcare, manufacturing supply chains, and technology development. The model also has the potential to be integrated into other cooperative models and frameworks. • Introduces a trust-based “neighborhood” model for multi-project delivery. • Two-study design: concept-test survey and codesign workshops. • Appeal is strong; concerns center on power and access. • Hub, trust exercises, and intermediate metrics emerge as mechanisms. • Policy guardrails proposed to ensure openness and fair risk sharing.
