We as the Contractor have a contract completion date in July 2020.
Within the Works Information we are required to provide 12 months of maintenance to the landscaped areas on site, we have included this requirement within our landscaping subcontract, as a lump sum item within the subcontract BOQ (the landscaping subcontract is yet to be executed).
The subcontract completion date was drafted as July 2021 to account for the 12 months maintenance period required, following completion of the main works.
This has however been flagged by others as incorrect, on the basis that subcontract completion cannot occur after main contract completion, not to mention that the Subcontractors retention would not be released until a further 12 months after main contract completion, with the Subcontractors defects period starting 12 months after the Contractors also.
The premise of a July 2021 subcontract completion date was to allow for all works in the BOQ to be undertaken prior to subcontract completion, thus avoiding a situation whereby completion is certified and retention is released prior to all works being completed.
Can anyone advise the correct approach in this situtation?
