Strip out plan

We are tendering out project in 2 phases. 1 contractor will be brought on to provide a strip out (typical demolition services of a CI project). The main contractor will be brought on afterwards - who should create and take ownership of the waste management plan. Technically, the "actual" plan owned by the GC won't be in place when the strip out is completed. There will be a "plan" for the strip out contractor to follow - document, recycle, provide photographic evidence etc as typically required if an "actual" plan was in place. This would then feed into the "actual" plan retrospectively. Although not under the main contractor - can the credit still be achieved? My view is that the aim of the credit is met and the documentation and calculations provided will be the same. The strip out contractor will be under the same obligations - it's just a matter of timing with the plan being created retrospectively. Thanks in advance.
