BAM Nuttall angered at release of report! - Why?

In this weeks News and Crier there is a piece about BAM Nuttall being angered that Cambridgeshire County Council released a report. Why are they angered? This is a project paid out of taxpayers money and we, the people, should be told what is being done for us. Too many contracts are kept secret for "commercial reasons" though these reasons are rarely expanded upon.

The Conservatives at national level want these contracts to be published. I find it a pity that CCC is selectively publishing information rather than just publishing everything.
