The document discusses the differences between general conditions of contract (GCC) and special conditions of contract (SCC). GCC contains standard terms and conditions that apply to all contracts regardless of factors like nature of work or supplier type. SCC relates to terms specific to a particular contract that can vary depending on contract specifics. It is not advisable to change GCC as it has long term legal implications, but SCC for a specific contract does not carry the same level of implications and is more tactical in nature. GCC is more strategic while SCC allows for changes specific to a contract or event.
