Geocache Description:

This is a quick offset cache located near the now defunct South Gippsland Railway Line. The coordinates mentioned above are of the original station. You cannot get there (unless you have a helicopter) because of the Desal pipeline and the blackberries which seem to cover most of this railway line now. There is very little information available in the public domain on this station so I am not sure of why the station was put here.

However after much Googling we have found an interesting little story about a reinforced concrete water tank that was designed by John Monash in the early 1903-04.

A lot more information can be gained on John Monash’s career at the link above.

Location: MacMillan Bros Homestead, Caldermeade Estate.
Fate: Believed demolished in 1980s. (Information from Lang Lang and District Historical Society)
Firm: M&A.
Designer: John Monash.
Client: MacMillan Bros.
Initial Design: June 1903.
Definitive Design: September 1903.
Construction: November 1903 to January 1904.

HISTORY

On 17 June 1903 David Mitchell dropped in to the M&A office and left a message asking for a sketch of a 10,000 gallon tank about 8 feet high. Monash made the preliminary calculations the same day, but took a few more days to estimate his costs and decide on an appropriate margin for contingencies and profit. On 3rd July he wrote Mitchell that the "Monier Tank and troughing for your friend at Caldermeade" would cost £95. Following the design of more elaborate foundations (for a clay soil) the price was raised to £100 and the MacMillans gave the go-ahead. They advised that Monash's foreman Charley Savage could board at Lang Lang, about 7 km from the site, and promised to lend a horse and trap or bicycle.

Monash issued Savage with precise instructions, military-style:

1. Proceed to Caldermeade Estate, Caldermeade, Messrs Mc Millan [sic] Bros. Homestead and ascertain the exact position for the tank.

2. Carefully examine the ground, and get full information as to its nature. Sink a hole about 2'-3" deep and ascertain where clay is struck.

3. The total concrete required will be about as follows:
(a) For the work at and below ground level 10 1/3 c. yds.
(b) For the work above ground level 4 2/3 c. yds, Total: 15 c. yds.

4. Look for and make definite arrangements for the supply of the following materials:
(a) Fine sand, similar to Sample A, about 2 c. yds.
(b) Coarse sand, similar to Sample B, about 15 yards.
(c) If any coarse gravel or shingle or hard broken bricks, or limestone is available, get up to 5 c. yds of this instead of sand.
(d) See if it is possible to make satisfactory arrangements for the thorough washing of 4 yards of coarse sand.
Note: All the above is c. yds, not loads

5. The man who supplied the first two samples of sand is called Glasheen, enquire for his whereabouts.

6. Look around to see what the best arrangements are that can be made for the temporary storage of about 20 casks of cement.

7. Look around to see what timber is available to serve as uprights for frames, staging or other purposes.

8. Make a complete list of all tools and appliances you will require for carrying out the work, and ascertain before leaving the Estate which of these articles you can borrow from the owners.

Construction was delayed by bad weather and completed in January 1904. Some problems were encountered with leakage and the MacMillans withheld final payments until this decreased to an acceptable level in July 1904. They enquired about the cost of further tanks for other windmills, but there is no evidence in the UMA or NLA records of any further contracts.

Technical Description

Monash's initial design in June 1903 had a cylindrical wall, of outside diameter 16'-6", varying in thickness from 2½" at the top to 4" at the bottom. The lowest foot was to be reinforced with 5 bars 3/8" in diameter. The floor was to be plain concrete, 6" thick. Around the base was a trough for cattle, two feet wide and one foot deep. The estimated cost after some revision was £62 to which £32 was added to cover contingencies and profit. In September, a circumferential ground-beam was added and the floor was reinforced and made thinner, but with a thickened portion at its centre. The troughing was supported on radial brackets projecting from the ground-beam. The cost increased to £71 and the price to £100.

Riveting stuff this isn’t?

However in order to find this cache you will need some info from the above article and have a “Chirp” enabled GPS receiver.

S38 AB.CDE

E145 FG.HIJ

Where;

AB = Year of completion minus 1890.

CDE = Original quote plus 560.

FG = Estimated cost minus profit plus cubic yds of fine sand.

HIJ = Diameter of tank in whole centimetres (rounded up) minus 6.

Go to the location shown above where you should receive a “sign” on where GZ will be.

After that it will be an easy find and there is a gift for the First to Find.

Please replace carefully, especially if you are doing it at night. There could be some nighttime traffic on the side road so please take care in retrieving and replacing the cache.

Please remember to bring your own pen.
