Access

Bookings are made through Survey Services, Infrastructure Delivery Branch, City of Gold Coast—refer to 'Contacts'. Access keys are to be collected from the Survey Services office and returned there immediately after finishing at the baseline.

Access to the wastewater treatment plant is longer required as the entire baseline is now outside the treatment plant grounds. Baseline is access from the eastern end of Shelter Road only. No access is allowed to the baseline through the wastewater treatment plant.

Design

Type: 7 station Schwendener. Stations are concrete pillars.

Datum RL: The datum plane is based on reduced level (RL) 0.0 metres. RLs for the stations are derived from station 2—permanent survey mark (PSM) 130128.

Alignment: Base alignment is from station 2 to 8. Offsets are negative to the left and positive to the right of the line viewed from station 2.

PSMs

Notes

• Mangroves grow adjacent to this baseline and are protected native flora. Any mangroves blocking visibility between pillars are to be reported to the Gold Coast City Council using the contact numbers provided below. Do not interfere with mangroves.
• The security gate on Shelter Road between pillars 2 and 3 is to be locked shut when the baseline is not in use.
• Use appropriate signage when using this baseline and limit vehicular travel to an acceptable speed.
• Pillar 1 (PSM130127) has been damaged and is no longer used. Pillar 8 has been constructed as a replacement.
• Pillar 2 is subject to flooding.
• Fluctuating air temperatures around station 4 are most likely caused by the runway and have been known to impact on results of high-accuracy observations.
• This baseline has been known to show occasional movement. Take care when carrying out observations more than 1 year after the baseline was last calibrated.
