2 EXECUTION

2.1 EXISTING SERVICES General Requirement: Before commencing earthworks, locate and mark existing underground services in the areas which will be affected by the earthworks operations including excavating. Utility services: Contact DIAL BEFORE YOU DIG to identify location of underground utility services pipes and cables. Excavation: Do not machine excavate within 1 m of existing underground services.

2.2 TREE PROTECTION General Warning signs: Display in a prominent position at each entrance to the site, warning that trees and plantings are to be protected during the contract. Remove on completion. Lettering: Road sign type sans serif letters, 100 mm high to AS 4970 Appendix C. Protection measures: Provide before commencement of earthworks. Tree protection zone (TPZ):



To AS 4970 Section 3. As per the Australian Standards AS 4970-2009 Protection of trees on development sites the tree protection zone (TPZ) is the principal means of protecting trees on sites where development is to occur. The TPZ is a combination of the root area and crown area requiring protection. It is an area isolated from construction disturbance, so that the tree remains viable. The radius of the TPZ is calculated for each tree by multiplying its DBH x 12. E.g. DBH is 0.5m x 12 = 6m radius (TPZ = 6m measured from the centre of the trunk at ground level.) If the proposed encroachment is greater than 10% into the TPZ or SRZ an Arborist must demonstrate that the tree(s) would remain viable. Once proposed changes or designs of the site are completed the project Arborist may need to re-inspect selected trees to ensure the trees are adequately protected. The purpose of this is to determine the potential impact on trees proposed to be retained. Structural Root Zone (SRZ): A structural root zone area of a tree is required for tree stability. Using Australian Standards AS 4970-2009 Protection of trees on development sites the structural root zone area can be calculated when major encroachment into a TPZ is proposed. This zone considers a tree’s structural stability only and not the root zone required for a tree’s health and long-term viability, which is usually a much larger area. (As cited by AS 4970-2009) An indicative SRZ radius can be determined from the trunk diameter measured immediately above the buttress using the following formula. SRZ radius = (D x 50)0.42 x 0.64 or using the following guide from AS 4970-2009. Eg. Diameter at root flare is 0.8m (red circle) and using the graph below a 3m SRZ radius is required. This is measured from the centre of the trunk at ground level. Key considerations to be noted by the Contractor when constructing near trees: - More than 90% of trees’ roots are located in the upper 1.0m of soil depth and tree roots generally

extend well beyond the canopy spread of the tree. - Machinery and vehicle movements in proximity to trees and the stock piling of building materials

beneath trees can damage both tree roots and the lower sections of the canopy. - Stock piling of building materials beneath trees can damage both tree roots and the lower sections

of the canopy. - Where trees are retained it is crucial that contractors and sub-contractors are informed of the likely

extent of tree roots and the potential damage to roots and lower branches from the construction of infrastructure too close to trees.

Key actions to be undertaken by the Contractor when constructing near trees: General: The Contractor is to ensure all contractors and sub-contractors are informed of the likely extent of tree roots and the potential damage to roots and lower branches from the construction of infrastructure too close to trees. Fencing: - Tree Protection Fencing is erected around each tree or groups of trees to prevent damage to

canopies and the root zone, where practical. Where this is not practical the Contractor is to nominate another method of protection.

Harmful materials: Conform to the following: - Machinery and vehicle movements in TPZs of trees to be retained are to be minimised. - Stock piling of building materials in TPZs of trees to be retained is not permitted. - Keep the area within the dripline free of construction material and debris. - Do not place bulk materials and harmful materials under or near trees. - Do not place spoil from excavations against tree trunks. - Prevent wind-blown materials such as cement from harming trees and plants. Damage: Prevent damage to tree bark. Do not attach stays, guys and the like to trees. - Where damaged, roots are to be cleanly cut using a hand saw or secateurs. An Arborist is to be

advised if more than 3 x 30mm diameter roots are cut on any tree which is being retained to ensure the trees remain low risk and structurally stable.

Work under trees: Do not remove topsoil from, or add topsoil to, the area within the dripline of the trees. Soil levels around trees out to the TPZ radius are not to be raised or lowered unless otherwise documented. Excavation: Minimise period of excavation under tree canopies.



- When clearing the site and removing overburden, excavators should be fitted with a flat edge bucket and a spotter employed to check for tree roots.

Hand methods: Use hand methods to locate, expose and cleanly remove the roots on the line of excavation. If it is necessary to excavate within the drip line, use hand methods so that root systems are intact and undamaged. Roots: Do not cut tree roots exceeding 50 mm diameter. Where it is necessary to cut tree roots, use cutting methods that do not excessively disturb the remaining root system. Immediately after cutting, water the tree and apply a liquid rooting hormone to stimulate the growth of new roots. Backfilling: Backfill excavations around tree roots. Place the backfill in layers of 300 mm maximum depth and compacted to a dry density similar to that of the original or surrounding soil. Do not backfill around tree trunks to a height greater than 200 mm above the original ground surface. Immediately after backfilling, thoroughly water the root zone surrounding the tree. Backfill material: - Mix proportions (topsoil:well-rotted composts) by volume: 3:1. - Neutral pH value. - Free from weed growth and harmful materials. Compacted ground: Do not compact the ground or use skid-steel vehicles under the tree dripline. If compaction occurs, give notice. Watering: Water trees as necessary, including where roots are exposed at ambient temperature more than 35°C. And to minimise stresses upon the trees to be retained the Contractor is to provide supplementary watering to the retained trees once per week with added wetting agent, approximately 600 – 1,000 litres per tree is required.

2.3 COMPLETION Clean up Progressive cleaning: Keep the work included in the contract clean and tidy as it proceeds and regularly remove from the site waste and surplus material arising from execution of the work, including any work performed during the defects liability period or the plant establishment period.
