Hosted by CoST, the Infrastructure Anti-Corruption Toolbox (IACT) will serve as a knowledge hub that brings together curated anti-corruption resources, risk identification and mitigation tools into a single, navigable platform. Using the OECD IACT Handbook as a starting point, the initiative builds on the knowledge hub paradigm, where the platform’s value increases with use as it aggregates intelligence from its user base. 

These Terms of Reference set out the requirements for engaging a web development consultancy to design, build, and support the IACT platform through a phased development approach. The phased structure reflects both the ambition of the platform and the practical need to deliver demonstrable progress at defined intervals, manage budget exposure, and incorporate learning from each stage into the next.
