We were awarded a contract for works in March, we started getting design works completed and visited site to complete a few activities in May after an initial delay by the Employer.
We then were off site until September. This was not our fault.
We were then issued a communication that stated September would now be our start date for the contract duration.
My question is, if we were actually awarded the contract (in writing) in March and were on site in May can they then change the contract start date? If so, in what form would this communication have to take place?
