Geocache Description:

As part of their 90th anniversary, Engineers Australia developed a booklet describing the story of Adelaide's engineering heritage. This cache is one of a series of five which gives you a walking tour of the sites.

The booklet is an interesting read and contains the four walking maps and links to the sites you will need to visit to complete this multicache. You can pick up a hard copy booklet at the Visitor Centre in Rundle Mall or at the South Australian Division of Engineers Australia.

Alert: You are about to download a file in order to obtain further details needed to find this geocache. As the cache owner, I represent that this file is safe to download although the files needed to complete this geocache have not been checked by Groundspeak or by the Reviewer for possible malicious content. As a result, you are downloading this file at your own risk.
You can download the booklet here.

The lid of each cache also contains a clue which will help you find the fifth cache.

Take some time to visit all the sites in the booklet; you'll learn more about 'the hidden profession' and discover some amazing things about our beautiful city!

Engineering a City #4: Central to South Adelaide

Waypoint	Site Number	Name	Question	Answer
EAC401	W29	McHenry Street (site where first automobile was built)	Head down McHenry Street to the former Stock Exchange, now the Royal Institution of Australia. The building has sprouted two sets of interesting LED displays. How many panels are in the display on the Eastern wall? (A prime more than 20 and less than 40)
EAC402	W30	Former Aerated Bread bakery – original chimney and cast iron downpipe by A C Harley can be seen in Cannon Street	Find the historical plaque about the building. It was used as a bakery until what year?
EAC403	W36	Former Marine & Harbors building – the front section was shifted north along rails to its present position in 1979	Don't demolish it, just shift it! Find and read the historical plaque about the building. How many tonnes does the façade weigh?
EAC404	W37	Cast iron benchmark 9, near the statue of Charles Cameron Kingston	How high above Low Water at Port Adelaide?
EAC405	E28	Destructor and disinfector station, Halifax Street (also site of former brewery, bakery and flour mill)	Find the copper braid earthing strap. Don't put your tongue on this in a lightning storm! The sign for the Heenan Patent Refuse Destructor is on side #1. Counting clockwise around the chimney, what side is the earthing strap on?
EAC406	E29	Southcott engineering works site, Gilles Street	This company built the machine which perforated Australia’s postage stamps in the early years of Federation! Find the sign with the micrometer which tells you they've been around since 1886. What is the entrance number below this sign?
EAC407	E31	Cast iron benchmark 10	How high above Low Water at Port Adelaide?
			Total (checksum = 27)
			Latitude decimal minutes = (Total + 2350.24)/100
			Longitude decimal minutes = (Total + 433.84)/100

The checksum should match the sum of all the digits in your total. To derive the latitude decimal minutes for GZ add 2350.24 to your total and divide by 100. To derive the longitude decimal minutes add 433.84 to your total and divide by 100.

Enjoy your walk through the city!
