This request for Powerline Vegetation Management works is for pruning of cultivated trees, growing within the vicinity of overhead powerlines, including Arial Bundled Cable (ABC) and service lines to properties, for a period of 3 years with two single year options at the City's discretion.

The City of Kalamunda requires the services of a suitably qualified and experienced Contractor to provide street tree pruning services for annual programmed and Western Power notified power line clearance works. The intention is for cultivated trees located under, or near distribution overhead lines to be pruned once annually, although additional pruning may be required for selected trees that grow quickly, traffic sight line clearance and road clearance pruning works.

The City manages approximately 11,000 cultivated* trees that require annual power line clearance pruning, although the Principal gives no guarantee of work volumes to the contractor.

*Cultivated and naturally occurring trees are defined in the 2012 Department of Commerce Energy and Safety, Guidelines for the management of vegetation near power lines.

It is the responsibility of the Tenderer to conduct sample inspections of the area and assess the trees therein. Unforeseen difficulties for which provision has not been made in the tender will not relieve the Contractor from the obligation to fulfil the contract.

The following standards are applicable to this tender.

Australian Standard AS4373-2007 'Pruning of Amenity Trees', and

Code of Practice for Personnel Electrical Safety for Vegetation Control Work near Live Power lines issued by the Director of Energy Safety, Energy Safety WA July 2012.

The contractor is to provide all labour materials, tools and equipment to carry out the task in an efficient and professional manner, including:

1. Traffic management.

2. Pruning for clearances

3. Removal and disposal of pruning's.

Bushfires are a risk within the City of Kalamunda. It is therefore necessary that all annual power line clearance works are to be commenced in our Western suburbs in March and completed in the more Eastern suburbs prior to 31st May each year. This period may need to be varied from year-to-year dependent on seasonal change, passive fuel reduction requirements and Department of Fire and Emergency Services fire ban dates.

The City operates a separate contract for General Tree Services, which includes works for unscheduled tree pruning, removal, chipping and stump grinding in public open space and road reserves and is outside the scope of this Tender.
