255 David Low Way, Peregian Beach. Lot 95/SP137431

 

A 37mm projectile and a 6lb Artillery projectile were placed at depths of 30cm and 50cm
(respectively). The Foerster 4032 magnetometer was tested over these items at the specified
depths.

The tests were carried out at the start and end of the UXO Remediation with positive results. Both
items were easily detected at the specified depths.

4.3. CONDUCT OF SEARCH

Prior to a deep search, | conducted a site “walkover” to look for any more obvious pieces of metal
detritus. After testing the search equipment over the test holes and test pieces, a shallow search
was then conducted over the site using the F3. Particular attention was applied to the site
perimeter and around obvious items that would interfere with the magnetometer (obstacles on site
listed below) Numerous shallow targets were investigated and all proved to be domestic rubbish.

The Site, where possible, was then subjected to a disciplined and systematic 100% UXO search
along nominally one (1) metre wide transect lanes utilising a Foerster 4.032 magnetometer as the
primary search instrument (supported by the Minelab F3 metal detector). The search operations
were conducted in a north-south direction with alignment being maintained using marking tapes
and aluminium marker poles. All metallic contacts were excavated and investigated using hand
tools.

There was some interference along the Eastern boundary of the site due to the overhead power
lines running along David Low Way. The magnetometer was still able to be used in an alternative
search mode (mode 6). The southern boundary consisted of a large building including a basement
car park below ground level. The magnetometer was not able to be operated within 5 meters of this
building and a shallow search was carried out along this boundary using a Minelab F3 metal
detector. The western and northern boundaries had a permanent and temporary 2m (plus) metal
fence in place (respectively) and again a shallow search could only be carried out along these
boundaries.

There were three further obstacles within the search area namely:

(1) A site office for the neighbouring construction. This building measured 3m x 3m and was
situated at the Northern end of the site.

(2) A large sign advertising XXXX Gold for the Bowls Club.

(3) An underground sewer line running diagonally from the NW corner to the SE corner of the
site.

A limited shallow search only could be carried out in the vicinity of these obstacles

A total of 41 deep targets were investigated in those areas that were able to be searched by
Magnetometer (approx. 80% of the site). Of these all proved to be domestic metal detritus in the
form of reinforcing steel, bolts, nails, concrete, etc. A lot of the items found were most likely
imported with the gravel / road base material or left over from neighbouring construction. Unused
underground electrical wiring was also evident in one location at the southern entrance to the site.

No evidence of military activity was found at all.
