of earthworks required to achieve the grades indicated on the grading plans.
1.6. LOCAL BUSINESS NOTES
Contractor is encouraged to maximise local industry participation in major procurement opportunities, by
providing local industry with full, fair and reasonable opportunity to tender.
The principle of full, fair and reasonable opportunity can be achieved by:
• considering the project’s whole-of-life from design to completion and ongoing maintenance
• ensuring at the tender preparation stage that tenders are packaged in a manner that optimises local
industry opportunities while enhancing project competitiveness and value for money
• undertaking a supply market analysis to identify potential local suppliers
• using Australia and New Zealand (ANZ) standards and codes ‘or equivalent’ in the formulation of
specifications, tenders and the letting of contracts, wherever it is practicable to do so
• providing early notice to the market of a planned upcoming major procurement
• encouraging sub-contractors to support and report against the charter principles
• using the services of local content specialists such as Industry Capability Network Queensland (ICN Qld)
and supporting the use of these specialists by sub-contractors.
Full, Fair and Reasonable Opportunity
The provision of equitable opportunity for capable local industry to participate in the procurement activity by
ensuring:
• Full: Local industry has the same opportunity as other potential suppliers to participate in all aspects of a
project from design through to completion, in all supply and ongoing maintenance.
• Fair: Local industry is provided the same opportunity as other potential suppliers to compete for
investment projects and other market based contracts on an equal and transparent basis.
• Reasonable: Tenders are free from any unreasonable specifications or requirements that could rule out
local industry and are structured in such a way as to provide local industry the opportunity to participate.
This definition is consistent with the Australian Industry Participation National Framework.
Procurement
Procurement is the entire process by which all classes of resources (human, material, facilities and services)
are obtained. This can include the functions of planning, design, standards determination, specification
writing, selection of suppliers, financing, contract administration, disposals and other related functions.

Cut and fill as required to complete the works. Assumption that civil earthworks will provide finished levels +/- 150mm from required landscape levels. Refer to Civil documents to confirm provided finished levels. Remove spoil and excess fill from site. The Contractor will be required to achieve smooth even grading to landscape areas. The Contractor shall allow to remove existing plant matter, debris, rubble or other loose materials likely to interfere with the new work, and consolidate the filling to all resulting excavations. The Contractor is required to carry out final trimming of the entire works of the grades. Any areas of discrepancy from the Drawings should be brought to the attention of the Landscape Architect. Fine grading shall be undertaken with a tolerance of ± 25mm. Spot levels take precedence over contour lines and ground profile lines. The subgrade is to be compacted to 95% minimum dry density ratio (+ 0mm- 25mm of design levels) prior to sub-base placement. Any areas of soft ground are to be excavated & replaced with suitable fill and compacted to prevent subsidence. Provided that all areas are free draining, and no ponding of water occurs. Subsoil drains to have minimum fall of 1:100. Filling in layers approximately 150 mm thick compacted to 85% of the dry density ratio of the surrounding soil as determined by AS 1289, to minimise slumping and further internal packing down. Corners and intersections of planes shall be rounded gradual and curves generous. To grading from edgings, provide horizontal shoulders, minimum width 500 mm, before any change of level. Earth Mounds Planting mounds shall be formed from topsoil to the depths as required. The profile shall be such that the placement of topsoil, soil mix and mulch shall bring the mounds to the finished levels shown on the drawings. Slopes to mounds shall be no greater than 1:3 unless otherwise shown on the drawings. Ensure existing ground levels in locations of mounds are deep ripped 150mm prior to formation of mounds. Rake over all mounds for smooth profile. Filling in layers as stated above. 3.5. SETTING OUT Prior to commencing each stage of the Landscape works, set out alignments of all paths, walls and planting must be inspected and approved by the Landscape Architect.

6. SOIL 6.1. GENERAL SPECIFCATION Quality assurance and control Soil sample testing results are to be provided to ensure soils meet the specification requirements prior to installation. If the samples do not meet the performance specification corrective actions have to been undertaken with no additional cost to the Superintendent. Samples reports are to be submitted to the Landscape Architect, and written approval to be obtained before using the soil. All testing as required by the product specifications must be arranged by the Contractor, and carried out by an accredited laboratory. The test certificate will be accompanied by a statement of compliance from a competent person (e.g. qualified agronomist horticulturist or soil scientist). Testing facility shall be SESL Laboratories. Compliance certificates will be in the form of a report clearly stating the material is compliant, with an attachment showing the test results. In the case of minor non-compliance or substantial compliance, a clear statement must be obtained from a qualified independent agronomist waiving the compliance and certifying the sample is compliant with or without conditions. Soil testing All laboratory testing of work carried out shall be performed by a soil laboratory with the NATA and are to conform with all relevant Australian standards. Site soil sampling shall be carried out in locations selected by the Landscape Architect. Recommended soil laboratory is SESL Australia. No soil will be purchased or installed until initial compliance testing certification has been demonstrated and approved by the Landscape Architect. Delivery dockets for all imported soil is to be provided to the Landscape Architect immediately upon delivery, to demonstrate the approved soils are being supplied. Manufacturer’s product representation For imported soils from manufacturers, a ‘product representation’ document produced by the supplier may be accepted as a compliance certificate if: • it is an off-the-shelf product line, not a custom mix • a representative test certificate is available and is acceptably recent (within 1 month) • the testing covers all those criteria in the URBIS performance specification and complies • the manufacturer’s quality assurance system is externally certified. Quality control during construction The contractor must submit samples of blended soils or imported soil mixes at regular intervals during construction for the purposes of demonstrating continued compliance of quality control. Test submissions & Frequency Submit representative samples of ~5 kg of each product specification, packed and labelled to indicate the source and the specification to be met. The samples must be taken in a representative manner. The contractor must refer to the testing frequencies indicated in Table 1. Variations to the frequencies in this table are permitted on the submission to the Landscape Architect of an alternative testing program that clearly achieves the desired outcome of quality control. Materials supplied from operations that have a third- party-endorsed quality assurance program may be acceptable pending submission of the relevant documentation. URBIS URB -P0003847-001-SP PAGE 12

9. PLANTING 9.1. GENERAL SPECIFICATIONS Quality All plants 45L and over are to conform to NATSPEC's ‘Specifying Trees - a guide to assessment of tree quality’, Second Edition 2003 by Ross Clark. The Contractor is to supply the Landscape Architect with a written compliance certificate from a qualified Arborist. All plants are to be vigorous and appropriately acclimatised with a rootball that is full but not restrained. The root ball and canopy of all plants are to be balanced and the stem / trunk sufficiently developed so that the plants stay upright without staking and/or guying. The Contractor must inspect plants / transplants immediately after being unloaded to check quantity, quality, vigour, health, crown balance (+/ - 20% from stem axis) and symmetry, crown density, pests (< 10% of foliage), growth uniformity (max. internode <1.2 x shortest internode), included bark, sun scald, root division / direction (>90% down and / or outwards) and occupancy (> 90% rootball intact when removed from container) and rootball soil volume. Sampling Partial destructive sampling as outlined in NATSPEC's "Specifying Trees - a guide to assessment of tree quality" is likely to be carried out on some trees and plants. Trees and plants that fail may cause entire batches of trees and plants to be rejected. Plant Substitutions Any potential species substitutions or changes to nominated container or canopy sizes are to be noted in the tender as potential alternatives. Specified tree species and size to be provided as the submitted tender. Palm Heights Palm heights are measured from the rootball surface to the base of the frond shaft for smooth trunk palms such as Bangalow, Alexander and Royal Palms. Heights are measured to the base of the lowest fronds (after any required frond pruning / removal) for rough trunk palms such as Canary Island Date Palms, Livistonas and Washingtonias. Palm heights are never measured to the tip of the fronds. Installation Plants are to be installed in the locations shown on the planting plan. The tops of root balls of plants 45L and over are to be level with or up to 50mm higher than the surrounding soil level. Create watering "saucers" around all plants from containers larger than 5 litres (ie 200mm diameter). Do not pile up mulch against the base of the plant stem/trunk. URBIS URB -P0003847-001-SP PAGE 22
Page 27
9.2. PLANT INSTALLATION Plant Installation: 200L – On Grade Planting hole - Excavate a hole no deeper than the rootball. The hole is to be 3 times the diameter of the rootball. Rip the sides of the hole prior to planting. Watering dish - Form a 100mm high, 1400mm diameter mounded soil watering dish around the tree. Infill the watering dish with mulch. Fill the dish with water regularly during the initial plant establishment period. Staking - Drive stakes into the ground, to approximately one third of their length, avoiding damage to roots. Install 3 times 50mm x 50mm x 2400mm stakes. Provide ties fixed securely to the stakes, one tie at half the height of the main stem. Others as necessary to stabilise the plant. Installation – Install as per manufacturers details. Re-tension after planting to provide a slightly loose fit, allowing for main trunk and canopy movement, which will provide wind support and promote root and stem growth. Notes: As per Noosa Shire Council requirements Plant Installation: 100L – On Grade Planting hole - Excavate a hole no deeper than the rootball. The hole is to be 4 times the diameter of the rootball. Rip the sides of the hole prior to planting without disturbing the interfacing road sub-base. Watering dish - Form a 100mm high, 1000 mm diameter mounded soil watering dish around the tree.

11. ESTABLISHMENT MAINTENANCE 11.1. 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. 11.2. 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. URBIS URB -P0003847-001-SP PAGE 27
Page 32
Soil testing Provide detailed chemical and physical test results of the root plate of each tree and backfill soil 2 weeks prior to the completion of the Establishment Maintenance period. Rectify any identified chemical or physical soil imbalances as per the testing laboratory recommendations prior to the completion of the Establishment Maintenance period. 11.3. ESTABLISHMENT MAINTENANCE LOG Keep a detailed maintenance log of all activities undertaken including watering regimes and fertiliser applications. This log is to be given to the Landscape Architect and Facility Manager at the completion of the Establishment Maintenance period. URBIS URB -P0003847-001-SP PAGE 28
