SUMMARY

Comply with the National Construction Code, Acts, Regulations, Australian Standards and Other Standards referenced in this specification. Compatibility of Materials: Ensure materials which are used are compatible with all other materials which may be affected. For example: floor covering adhesives must be compatible with the substrate sealing system used. Making Good Repair any damages caused during the execution of the works. Leave the works and the site of the works in a neat and clean state on completion of the works. Manufacturers or suppliers’ recommendations Select, if no selection is given, and provide, transport, deliver, store, handle, protect, install, finish, adjust and prepare for use the manufactured items in accordance with the current written recommendations and instructions of the manufacturer or supplier. If materials or products are supplied by the manufacturer in closed or sealed containers or packages, bring the material or products to the place of use or installation in the original containers or packages. Proprietary Items: Identification of a proprietary item does not necessarily imply exclusive preference for the item so identified, but indicates the necessary properties of the item. If alternatives are proposed, submit sufficient information to the Superintendent to enable evaluation of the proposed alternatives. Standards: Use Standards, and their amendments, current 3 months before the date for the close of tenders except where different editions and/or amendments are required by statutory authorities, including, but not limited to, NATA and the National Construction Code including the Building Code of Australia.

SITE PREPARATION

Site Clearing

Limit clearing to areas of cut and fill and areas to be occupied by works, such as structures paving, excavation, regrading, and landscape work or to other designated areas to be cleared.

Remove everything on or above the site surface, including rubbish, scrap, grass, vegetable matter and organic debris, scrub, trees, timber, stumps, boulders and rubble. Remove grassed soil to a depth just sufficient to include the root zone.

Mulch all demolished above ground vegetation and reduce to pieces not larger than 75 x 50 x 15 mm and stockpile for reuse or remove from site.

Grub out or grind stumps and roots over 75 mm diameter to a minimum depth of 500 mm below subgrade under construction, buildings, embankments and paving, and 300 mm below the finished surface in unpaved areas. Backfill holes remaining after grubbing out or grinding with sand material to prevent ponding of water. Compact the fill material to the relative density of the existing adjacent ground material.

Extent: Areas of cut or fill and areas occupied by structures, pavement and embankments.

Maximum depth: 200 mm

Stockpile site topsoil required for re-use and imported topsoil where necessary. Establish stockpiles to a maximum height of 1.5 m. Protect  stockpiles from contamination by other excavated  material, weeds and building debris.

Take possession of surplus material and remove it from the site. Remove cleared, grubbed and ground material from the site. Dispose of this material legally.

Excavation

Site surface: Excavate the site to give correct levels and profiles required for construction, site services,  paving, and landscaping. Allow for compaction or  settlement or heaving.

Excavate for footings to the required sizes and depths.  Provide a clear space under timber or steel bearers Minimum clearance 400 mm.

Before commencing excavation, locate and mark existing underground services in the areas which will be affected by the ground works operations including clearing, excavating and trenching. Contact DIAL BEFORE YOU DIG to identify location of underground utility services pipes and cables. After excavation, confirm that the foundation conditions meet the design bearing capacity.

Surface Preparation

Stripping: Prepare the ground surface before placing fill (including topsoil fill) ground slabs or load bearing elements: To AS 3798 clause 6.1.5. Remove loose material, debris, organic matter and materials which will inhibit or prevent satisfactory placement of fill layers and compact the ground to achieve the required density.

Piling

After excavating bored piers, remove loose material and water from the base and confirm the bearing capacity. Do not allow loose material to fall down the hole before or during concreting; provide a liner if necessary.

Service Trenches

If practicable, make trenches straight between access chambers, inspection points and junctions, with stable sides as near to vertical as possible and uniform grades.
