Description
The contract value and term have both been increased.
Rationale
Need for modification brought about by circumstances which a diligent contracting authority/entity could not foresee: The increase in contract value and term were necessary due to the requirements of the Building Safety Act 2022. At the time of the procurement, it was unforeseen that the Building Safety Regulator (BSR) approval process would be lengthy and delay the project completion date.
