Q4. How can we make changes on the estate?

The MOD has a right under the Aquatrine contract to make changes. They can do that in two ways:

1. Instruct us themselves under Clause 43.5 and give STS a Work Instruction and we will carry out the works, or
2. Remove that part of the network from the MOD contract and carry out the work themselves or by their Contractors. They can achieve that removal by;
   a. A Partial/Whole Site Group Disposal which would remove the area/whole site from Aquatrine.
   b. Schedule 23 which would temporarily/permanently remove the area from Aquatrine.
