At the completion of the Maintenance Period, Council will inspect the landscape worksbefore signing off for Handover, and accepting responsibility for any future maintenance.During this Maintenance Period, horticultural best practices must be undertaken to ensurequality workmanship throughout the project site, before Council will accept the works.Council has certain expectations of acceptable landscape quality. The following clauses area list of minimum procedures that the Contractor is required to undertake during theMaintenance Period to ensure a quality, well maintained landscape is handed over toCouncil following completion of the Maintenance Period.

A maintenance programme is required to be submitted by the Contractor to theSuperintendent no less than one month prior to the commencement of the MaintenancePeriod. The programme should be prepared by a qualified horticulturist and should detail aproposed monthly maintenance programme, for the length of the Maintenance Period,covering operations addressing each of the sub-clauses below. The Contractor shall beresponsible for undertaking all works under the approved maintenance programme, with alllandscape plantings to be established and adequately maintained in-situ throughout the fullduration of the Maintenance Period in accordance with Clause 8300.8.7

8300.8.1 General

Rubbish or debris that builds up on site must be removed on a regular basis as part of anymaintenance. Council will not accept at handover, any garden beds that are littered withrubbish and other debris.

Within new park areas, forming part of the works, the Contractor is responsible for all upkeepof any furniture, drinking fountains, bins, etc. This may include, but not be limited to, thesweeping of pathways, cleaning of furniture and a regular checking of any play equipmentthat may have been installed as part of the works.

8300.8.2 Watering

Watering of all plants (via irrigation, water truck or other approved operations), from the timeof planting through to the commencement of and throughout the Maintenance Period, shallbe conducted at regular intervals as required to maintain plant grown free of water stress.

Watering equipment and operations shall be such that water pressure or concentration offlow does not negatively impact landscaping areas through wash-out, or create ponding oroverspray of adjoining roads, paths, buildings, infrastructure and properties.

Where the Maintenance Period is specified as the minimum 12-26 weeks (depending onproject scale) for mass planting and a minimum period of twelve (12) months for trees,watering operations shall achieve the minimum volumes and frequencies scheduled in Table4.

Based on the evapotranspiration data for the Mackay Region available through theQueensland Bureau of Meteorology, the following seasonal adjustment rates may serve as aplanning guide only for determining adjusted seasonal water volume rates on the volumesscheduled in Table 4 and Table 5:

a) Summer (Dec-Feb) – x 1.6

b) Autumn (Mar – May) – no adjustment

c) Winter (Jun – Aug) – x 0.8

d) Spring (Sep – Nov) – x 1.2

Notwithstanding adjusted watering volumes, the Contractor shall be responsible for ensuringsufficient moisture is maintained in the soil throughout the Maintenance Period in sufficientquantities to retain soil moisture content and promote plant growth after the installation ofvegetation treatments.

Adjusted rates shall be scheduled in the maintenance program submitted by the Contractorfor the approval of the Superintendent.

The contractor is to provide a log book or maintenance record of watering and maintenanceactivities carried out during the required Maintenance Period. This is to be presented to theSuperintendent with the monthly invoice claim.

The contractor shall ensure that all plantings are regularly watered from acceptance of plantdelivery through to planting and during the maintenance and establishment period. Allplantings shall be thoroughly watered immediately prior and after to planting. Failed plantingwithin the establishment period shall be replaced at no cost to Council.

8300.8.3 Mulching

Mulch depths throughout the Maintenance Period are to be maintained at the required depth.The Contractor is responsible for mulch replenishment operations as necessary to ensurespecified mulch depths are achieved at handover.

8300.8.4 Stakes and ties

Tree ties and stakes are to be regularly checked (minimum once per month) for tightness.Any tree stakes that interfere with the tree branching system are to be repositioned or cutback to allow the canopy to branch without harm, or prevent rubbing against the stake. Treesshall be re-staked, or have additional staking provided as required to ensure tree stabilityand straightness throughout the Maintenance Period.

8300.8.5 Weed Control

A weed management plan is to be implemented to control weed growth throughout theMaintenance Period. Spraying of weeds is permitted under the correct environmentalconditions, and to manufacturer’s specifications. At handover all garden beds are to be freeof weeds.

Weed and erosion control matting is to be repaired where damaged or loosened fromcontact with the ground, to maintain the weed suppressing, erosion control function, andmaterial integrity of the matting.

8300.8.6 Fertilising

Where specified the Maintenance Period exceeds the minimum 12 weeks, all turfed areas,seeded areas, planting areas and trees are to be fertilised once at the completion of each 6month interval of the Maintenance Period (in addition to the initial fertiliser specified at thetime of planting). This is to sustain healthy growth and vigour, and fight off any potentialdisease or insect attacks throughout the full duration of the Maintenance Period. Fertilisingshould generally be undertaken at the end of the summer and winter seasons (typicallyFebruary and August respectively) where practicable. Adjust timing of fertilising treatmentsas required to the approval of the Superintendent.

8300.8.7 Plantings

The need to prune or trim back may arise during the Maintenance Period. A qualifiedhorticulturist, or arborist where trees are involved, is to be employed to do all of thenecessary work, in accordance with AS 4373. The nominated horticulturist/arborist shall beapproved by the Superintendent prior to the commencement of the Maintenance Period.There are strict procedures to follow when undertaking any pruning works and badworkmanship that may lead to long term disfiguration or deformed growth (i.e. theunnecessary removal of a tree’s main leader) of trees and shrubs will not be accepted andthe affected plant shall be replaced at the Contractor’s cost.

At the first sign of any pest or disease attack, planting shall be treated with the specified (orapproved) pesticide treatment till such time as the pest has been determined to beeradicated by the Superintendent.

The Contractor shall replace failed planting throughout the specified Maintenance Period.Failed planting includes missing plants as per the Drawings, dead, dying,deformed/disfigured, unhealthy, badly damaged, diseased, extremely water stressed orotherwise non-recoverable plants nominated by the Superintendent as unviable. Identifiedfailures shall be replaced by the Contractor, and be of similar size and quality, and ofidentical species and variety to the original plant being replaced, unless otherwise directedor approved by Council. The cost of replacement planting will be borne by the Contractor.

Furthermore, it is a compliancy requirement that failed planting be replaced regularly andprogressively throughout the Maintenance Period as soon as practicable followingidentification of the failure. This is to maximise the establishment timeframe for planting priorto Handover to Council. The Contractor shall not undertake the required replacementplantings as a deferred, single operation immediately prior of the Maintenance Period enddate. The Contractor will be responsible for ensuring that at any time throughout the entireMaintenance Period, planting does not exceed the following maximum failure rates:

a) 20% failure rate of any particular species for container stock < 300mm in size;

b) 15% failure rate of any particular species for container stock 300mm and 25L; and

c) 10% failure rate for any ≥45L stock.

Council will notify the Contractor to undertake joint inspections of the planting no more than28 days from the specified Maintenance Period end date. Where planting exceeds theabove specified failure rates, landscape plantings will be determined as unacceptable,causing an extension of the Maintenance Period for an additional 12 weeks to ensuresufficient plant establishment time prior to Handover. The Contractor shall remainresponsible for replacing failed stock to achieve the required survival rates throughout theextended Maintenance Period.

Notwithstanding the above, the following plant failure rates are the absolute maximum thatwill be accepted by Council at the end of the original or extended Maintenance Period anddeemed acceptable for Handover:

a) 5% failure rate of any particular species for container stock < 300mm in size;

b) 2% failure rate of any particular species for container stock 300mm and 25L; and

c) 0% failure rate for any ≥45L stock.

8300.8.8 Grassed areas

All grassed areas within Council reserves are to be maintained during the MaintenancePeriod. Grass is to be regularly mowed to keep the finished height to a maximum of 50mm.Through summer, this may involve weekly mowing (depending on grass species), andthrough the cooler months, once every three weeks.

For grass seeded areas, total area coverage of less than 90% over the entire area at thetime of the ‘off maintenance’ inspection will not be accepted, and will cause an extension ofthe Maintenance Period by an additional 12 weeks , or until the required cover is achieved.Extensive or localised bare patches exceeding 5m2 are not acceptable.

8300.8.9 Turfed areas

Turfed areas shall be lightly top dressed with topsoil, four to six weeks after placement, tocorrect any undulations or unevenness in the established turf.

Coverage of less than 100% over the entire turfed area, at the time of the ‘off maintenance’inspection, will not be accepted, and will cause an extension of the Maintenance Period byan additional 12 weeks , or until the required cover is achieved. Localised bare patchesexceeding a total of 2m2 are not acceptable.

8300.8.10 Native seed areas

For native seed areas, coverage of less than the following will not be accepted, and willcause an extension of the Maintenance Period by an additional 12 weeks, or until requiredcover is achieved:

a) 75% cover crop coverage for the entire area twelve (12) weeks followingapplication; and

b) a minimum of one juvenile native plant species specimen per 9m2 (3m x 3m), atthe time of the ‘off maintenance’ inspection.

Determination of coverage will be established by random sampling over the treatment area.


Where an irrigation system is installed, regular maintenance is to be carried out to ensure itis in good working order. The necessary maintenance could include, but not be limited to:

a) cleaning of filters;

b) correction of timer settings; and

c) checking drip lines for blockages and leaks.

At handover, the Contractor must provide Council with the irrigation control manual,specialised programmers, any associated warranties and purchase certificates, and abreakdown of run times and lengths. It is also the Contractor’s responsibility to provide atest certificate, associated with the backflow prevention device, and application to MackayWater and Waste associated with the irrigations system installation. The loss of plants dueto lack of water will not be an acceptable excuse to Council.

A detailed ‘as constructed’ irrigation plan must be submitted to Council for records of conduitsleeve and pipe location and all irrigation components, prior to the end of the MaintenancePeriod.
