Dear Sirs/Madams,

RE: LEVEL 1 EARTHWORKS INSPECTION AND TESTING

SEVENTH BEND – STAGE 4 (MELTON SOUTH)

Please find attached our Report No’s 18453/R001 – 18453/R005 which relate to the field

density testing that was conducted within the filled allotments at the above subdivision. The

level 1 inspections and associated field density testing was performed in August 2018.

The inspections and testing of the earthworks was undertaken in general accordance with the

Level 1 requirements of AS 3798 - Guidelines on Earthworks for Commercial and Residential

Developments.

The site inspection and testing was performed by experienced geotechnicians from this office.

Any areas that were deemed unsatisfactory were reworked and retested under their

supervision. The testing was performed to the relevant Australian Standards and the

accompanying test reports carry NATA endorsement. The attached compaction results, which

were located randomly throughout the fill profile, are considered to be representative of the

bulk fill materials that were placed across the reported allotments by Winslow Constructors

during the aforementioned period. The approximate locations of the field density tests can be

seen on the attached plan (Figure 1).

We are of the view that the bulk fill materials that have been placed across the reported

allotments by Winslow Constructors during the aforementioned period can be considered as

having been placed in a controlled manner to a minimum density ratio of 95% (standard

compactive effort).

Please contact the undersigned if you require any additional information.
