Engineering Support Manual for Field Missions

The Engineering Support Manual for Field Missions provides a comprehensive foundation for the planning, delivery and management of infrastructure and engineering services across UN field missions worldwide. Designed as an essential reference for engineers, mission support staff and partner entities, the manual reflects the UN’s modern operational realities and its commitment to safe, efficient and sustainable mission environments.

This updated edition replaces the 1998 Engineering Support Manual and incorporates more than two decades of technological advancement, environmental stewardship and evolving organizational priorities. It brings together the latest policies, standards and best practices shaping today’s field engineering operations—from renewable energy integration and smart‑camp technologies to strengthened environmental performance and improved living conditions for uniformed personnel.

The manual also aligns with broader supply chain reforms and expanded collaboration across UN agencies, funds and programmes, ensuring that engineering support is consistent, coherent and adaptable across diverse operational contexts. In response to guidance from the General Assembly, it further provides clear standards for UN accommodation and practical direction for engineering compliance across missions.

Recognizing that field environments vary widely, the manual is designed to be applied with sound judgement, enabling each mission to adapt its provisions to local structures and conditions. It stands as a key resource for advancing resilient, responsible and mission‑ready infrastructure in support of UN operations globally.
