Further investigations for the Flinders Medical Centre consisted of geological mapping, trenching, seismic refraction surveys and five diamond drill holes to 23 m deep. This work confirmed the general distribution of geological materials across the...

A request for the Mines Department to investigate foundation conditions for five 2-storey office blocks to be built at Northfield was received from Mr. A. Dancauskis, Public Buildings Department, on the 3rd March, 1972, along with purchase order No....

Geological mapping shows that the reservoir area consists of Torrensian siltstones, dolomites and quartzites. These are strongly jointed with a pronounced slaty cleavage. The joints form three distinct sets. The geological structure is of uniformly...

This report contains downhole geological and wireline logging data summarizing the results of recent stratigraphic drilling in the Frome Embayment by the South Australian Department of Mines. Conclusions are tentative and may be subject to revision...

Materials at Long Creek crossing site are adequate for bridge foundations. Less favourable conditions at the Mabel Creek crossing site will require spread footings with low bearing pressures. Local materials at both sites are suitable for approach...

An investigation into rock stability conditions at Mount Barker was requested by Mr. Hutchinson of the Highways Department. The amended route of the South Eastern Freeway will now be through the quarry situated on the northern slopes of the mountain...

The Warrow Quartzite of Lower Proterozoic age is quarried periodically for railway ballast, 3 kilometres west of Darke Peak township, Eyre Peninsula. The quartzite deposit has been investigated by mapping and laboratory testing of samples. Los Angeles...

Investigation of foundation and excavation conditions for a 500, 000 gallon tank to be built at Salisbury Heights (Figs.1 and 2) was requested in a letter, dated 17th March, 1972, from the Director and Engineer-in-Chief of the Engineering and Water...

Investigation of the foundation conditions for a switch house for a new substation on Grange Road, Fulham Gardens (Figure 1. and 2) was requested in a letter dated 17th March, 1972 from the Civil Works Engineer Design of the Electricity Trust of South...

A masonary house at Tarana Road, Hope Valley, S.A with a "W.&G. No. 2" foundation movement in 1968. The regional geology of the area is outlined and results of the geological investigation consisting of two hand auger holes are presented. The...

Drilling to determine foundation conditions for the proposed Forensic Science and Motor Vehicles Buildings was requested by Mr. A. Dancauskis of the Public Buildings Department. The two buildings will be from 6 to 9 stories high, will have basements,...

Geological investigations indicate that no major foundation problems are anticipated. Physical testing shows that most materials are suitable as fill. Saline groundwater is available for compaction but no water suitable for concrete or camp use has...

Glen Osmond R.L. 850 one million gallon storage tank forms part of the E. & W.S. Metropolitan Water Supply. Excavation of the hill slope, to accommodate the tank, was completed in mid October 1971. Pouring of the lean mix concrete working surface...

A drillhole 47ft. deep was used to investigate the site for a proposed 250,000 gallon elevated tank at Berri. Due to the loose unconsolidated nature of the dune sand material (up to 29ft.), piling to the Bungunnia Limestone may be desirable....

The lay-out of the proposed rock fill dam and associated works is shown on Figure 1. Tenders are about to be called for construction of the diversion tunnel. The geological report to be supplied as additional information for tenderers is complete....

At the request of the Engineer for Water Supply, Engineering and Water Supply Department, an assessment was made into the significance of water losses from the Happy Valley Outlet Tunnel, and seepages and flows observed at the ground surface near the...

Diamond drilling of the Grampus Quartzite provided samples for laboratory testing. The Los Angeles abrasion value and the Plasticity Index are higher than those usually accepted for base course material. Reserves exceed 150 000 cubic yards.

The Government Offices building at Loxton has developed moderate to severe cracking during 1965. Two drillholes were drilled to total depths of 48 and 36 feet respectively to determine the cause and nature of the failure. Each hole penetrated from 26...

A single storey Loxton High School building has developed severe cracking during 1964 and 1965. Four diamond drill holes were drilled to depths of up to 40 ft. It was believed that the settlement and cracking is due to the collapse of the low...
