The builder/site manager will ensure that all appropriate sediment controls are in place before
the concrete pour starts. Any spillage that does occurred during the delivery procedure will be
swept up before removing the sediment controls and concrete spillage will not be hosed into
the stormwater system. Excess concrete will be returned back to the supplier’s depot.

Chutes, barrels, wheelbarrows and other equipment will be rinsed in the site wash-down area. To
minimise the amount of wash-down water generated, excess concrete will be scraped off
equipment before it is washed. Water in the wash down area will be contained and recycled as
required and not allowed to flow into the stormwater system. The chute contents will be washed
into the sediment receptacle drum and sealed with a lid before leaving the site. The drum will
be secured onto the main frame of the vehicle ready for transportation, and the drum will be
secured with a bracket that is easily accessible to the operator. The drum will be removed from
the bracket and the wastewater emptied into the designated treatment facility once the truck
returns to the yard with the wastewater containing suspended solids being recycled back into
the plant. The vehicle will be washed down at the depot.

Delivery vehicles will be on paved surfaces at all times and so no mud soil and or stones will be
carried off site as pollutants. An inspection of roads for any sediment that has been tracked off
site will occur and if any is present it will be sweep back on site (this will be done if there is threat
of rain and at the end of each day). A hose will not be used to wash it away).


INSTALLATION OF PILES AND CAPPING

Methodology for installation of hollow bar micro-piles as deep foundation support for the new
timber deck.

The micro-piles consist of one or more outer steel casings installed to the depths indicated on
the piling subcontractor (PCA) drawings. A central steel-reinforcing element consisting of a
40/20 hollow bar is to extend to a pre-determined design depth below the casing to form the
bond length and develop the applied load.

After checking the project drawings for the details of the micro-pile arrangement for each pile
location designed in accordance with the Tree Protection Plan, the Construction Management
Plan, and relevant environmental protection documentation and instructions, the rig will be
craned into position for the first pile onto a previously established level temporary protective
platform constructed in accordance with the tree protection plan and AS4970 - 2009.

Drilling will be carried out using a 90mm EXX drill bit using a rotary top hammer for installation
and all installation specifications accurately recorded for this and all subsequent piles.

The piles are grouted as the work proceeds and any excess grout is collected and pumped into
storage containment for offsite disposal in accordance with the concreting operations
environmental protection plan. The process is repeated for subsequent piles.

The onsite grouting pump will be contained within its own bunded area which will be kept clean
as the work proceeds and managed in accordance with the above Environmental Controls
Plan to prevent pollution from concreting operations during the construction.

Pile capping is to be managed in the same way as the grouting procedures.
