19.         ESTABLISHMENT MAINTENANCE

19.1.       GENERAL
The work contained in this section comprises the establishment maintenance of all works executed under
this contract. The Establishment Maintenance period begins at the issue of the Certificate of Practical
Completion. Maintain the contract areas for a period of 52 weeks.

Maintenance of the works prior to the date of Practical Completion shall not be included in this period.

If the maintenance period is extended, it is the Clients responsibility to meet the capital and maintenance
costs of elements that require refurbishment.

Promptly make good any defects or damage resulting from defective construction, materials or workmanship
to the complete satisfaction of the Superintendent during this period. The cost of replacement is the
responsibility of the Contractor. In the event of any failure to rectify defective work the Superintendent may
instruct that the work be carried out by another company, the cost of which will be charged to the Contractor.

Stolen items and plants are not included into the establishment maintenance. It is the Contractors
responsibility to source and plant or place them in coordination with the facility management.

It is the Contractors responsibility to highlight areas or items which may require additional maintenance
management to the facility management. These include emptying of rubbish bins, general regular cleaning
etc.

Prior to the Handover allow for a clean up to presentation standard of the entire landscape works area.

Tasks which are required on a 12-month interval are to be complete prior to the end of maintenance
compliance inspection. This includes all timber surfaces to be recoated with protective treatment as
specified.


19.2.       TREE TRANSPLANTING / PROTECTION MAINTENANCE
The start date for transplanted trees and palms begins the day the tree(s) or palm(s) are placed in their
proposed final location and backfilled. The period from the transplanting of all plants until the start of certified
On-Maintenance period is to be considered in addition to the required full maintenance period. The required
maintenance period is not completed until certified Off-Maintenance is granted.

Carry out all maintenance activities on the transplant(s) necessary to ensure they become fully re-
established within the Establishment Maintenance period and are returned to a healthy and vigorous state
with a min. 90% of the original foliage density (i.e. excluding epicormic growth).

Watering
The tree(s) may require large volumes of water to be applied by hand at the time of planting and repeated
twice weekly during the initial period (min. 6 weeks). Test, rectify and adjust the irrigation system or watering
regime as necessary to maintain optimum soil moisture levels in and around the root plate(s). The root plate
(and not the surrounding backfill soil) is the tree's main water source for many months after transplanting.
Ensure it is kept moist (but not over watered) at all times.

Wrapping
For thin or smooth bark trees, if more than 40% of the foliage is shed due to post-transplant stress then the
trunk and branches (greater than 50mm diameter) are to be wrapped with light coloured biodegradable
paper or hessian to reduce bark scalding. Wrap from the bottom of the trunk upwards so the layers overlap
and thus shed water.
