Government and NGO

We are proud to have strong partnerships and extensive experience working with governments and non-governmental organisations.

Our experience working with the government is comprehensive, with strong relationships developed over many years with many local authorities and government agencies through our work across national and regional public sector frameworks.

Public sector frameworks

ISG is proud to be on a number of public sector frameworks covering construction work across a variety of sectors. After over two decades of working on frameworks, we have honed a much-proven ability to deliver on time and on budget. Just as importantly, we have cultivated the expertise to provide focused insight, the dynamic culture to collaborate meaningfully, and the flexibility to enable efficient processes and deliver effective outcomes.
