The cache is not at the published coordinates. You will need to complete the Adventure Lab cache titled Coleman's Chronicles to get the information needed to calculate the final coordinates.
This listing is for the physical bonus cache for the Geocaching Adventure Lab cache. To learn more about how Adventure Lab caches work and how to find this new type cache, you can read about it here.

About Coleman's Chronicles
Welcome to Singapore's first Adventure Lab Cache!
In this Adventure, we will take a journey back to the founding of modern Singapore and walk in the footsteps of one George Drumgoole Coleman, an important but overlooked figure in the founding of this city. Coleman was a prolific and prominent architect in Singapore's early years and as Singapore's first municipal architect, he had a hand in designing many of Singapore's earliest buildings, many of them now gazetted as National Monuments. He also played a part of in the implementation of Raffles' Town Plan, and the contributed to the alignment of many of the main roads in Civic District. We will follow George Coleman's story in Singapore, beginning with his first construction commission from Sir Stamford Raffles in 1822 to his eventual passing in 1844.
There are 5 locations to be found, each representing a key event in Coleman's career in Singapore. The walk, including the bonus cache, is a one- to two-hour walking loop around the Civic District. There will be some mild hill climbing up Fort Canning Hill involved on proper park trails, but nothing too strenous. All answers to the question can be found on site, so no Googling involved. However, you will need mobile data coverage for the app to work.
Finally, a big thank you to all the intrepid testers: colincorgi, riskysurv, TheMTheory, kwek_ke and swirlywirly for taking some time off your weekend to play-test this cache!
The Bonus Cache
To find the bonus cache, you will need 5 clues from each of the 5 locations you visited for the Adventure Lab cache. The method of deriving the final coordinates is as follows:
STEP 1:
Calculate the value of (A + B + C + D + E) / 100. You should get a number in the form of XX.X where the three digits sum to 19.
STEP 2:
- To get the minutes for the northings, subtract 40.115 from XX.X found in Step 1.
- To get the minutes for the eastings, subtract 6.831 from XX.X found in Step 1.
STEP 3:
Check your answer in the Checker below, and make the short walk to the final. You should find yourself in a lovely little themed garden. Use the hint provided if you are stuck.
Good luck and I hope you enjoyed the lab cache and the walk!
