53 Spec 01 01 50, para

1.1.3 and 1.1.4

As per para 1.1.3 and 1.1.4, it is stated that the Phase of construction for Phase II and III shall not commence until the prior phase of construction is completed. Will it be acceptable to start Phase III without the completion of Phase II? This would be in an effort to complete by the end of SY19/20.

See amended specification section 01 01 50, paragraph 1.1.4.

Deleted reference to end of SY 19/20 as date of work completion.
