STAGE 1A (LOTS 1-9)BELIVAH ROAD - WINDAROO

Prepared for Belivah Pty Ltd page. 4

INTRODUCTIONConstruction Sciences was commissioned by Belivah Pty Ltd to carry out the geotechnicalinspection and testing required for Stage 1A of a proposed residential development at Belivah Road,

Windaroo which was carried out from 25th August to 6th September 2017.

SCOPE OF WORKSWorks on this development were monitored in accordance with the scope of our commission as

follows:-

Level 1 : Bulk earthworks stripping and filling was inspected and tested on a Level 1 basis, inaccordance with AS 3798.

Scope of Level 1 responsibility: “The primary objective of Level 1 Inspection and Testing is forthe geotechnical inspection and testing authority (GITA) to be able to express an opinion onthe compliance of the work. The GITA is responsible for ensuring that the inspection andtesting is sufficient for this purpose.

The GITA needs to have competent personnel on site at all times while earthwork operationsare undertaken. Such operations include the following:

(a) Completion of removal of topsoil.(b) Placing of imported or cut material.(c) Compaction and adding/removal of moisture.(d) Trenching and backfilling, where applicable.(e) Test rolling.(f) Testing.The superintendent should agree on a suitable inspection and testing plan prior to thecommencement of the works”.

reference AS3798 – Section 8.2

SPECIFICATION REQUIREMENTSEarthworks on this development was inspected and tested in accordance with the specification of thelocal authority, Logan City Council.

The following table is a summary of the basic compaction requirements for the project.

Testing procedures used to confirm that these requirements were met were all in accordance with

Australian Standard test methods.



SPECIFICATIONSItem Minimum Compaction RequirementBulk Earthworks Fill 95% Dry Density Ratio – Standard

SITE WORKS - BULK EARTHWORKSGeneral : Full time site inspection was maintained in accordance with Level 1 requirements whilstearthworks were carried out on this development. Fill areas covered by this report include residential

allotments 1 to 9.

The areas to be filled were stripped and proof rolled in accordance with the specification requirements.

Areas displaying instability were excavated until competent conditions were encountered.

The natural ground in the areas of filling generally comprised medium to high plasticity residual clays,

silty or sandy clays.

The material used in the bulk earthworks filling was sourced from site cutting to design levels.

Compaction Control Testing : Compaction control testing via the nuclear densometer method wascarried out at regular intervals throughout the placement of fill, in accordance with the minimum test

frequency recommendations included in AS3798 “Guidelines on Earthworks for Commercial and

Residential Developments”.

All test results are included in Appendix A. A summary of the test results is included as Table 1. A total

of 10 field density tests were carried out throughout the earthworks. The average dry density ratio was

recorded to be 103.2%.

CONCLUSIONWe confirm that:

(a) Our representative was in full time site attendance whilst bulk earthworks filling was in progressbetween 25th August and 6th September 2017 for :- Stage 1 (Lots 1 to 9) Belivah Road, Windaroo.

(b) Pre – fill ground preparation was carried out in accordance with the specifications and siteinstruction given.

(c) The structural filling placed to design levels during the term of our engagement on a “Level 1”basis can be termed “controlled filling”.



(d) The results of the compaction control testing indicate that the fill placed during the term of our siteattendance, was compacted to at least the minimum specified dry density ratio.

(f) All test results pertaining to the development are included within appendix A of this report.
