these were my 3rd and 4th ever survey job in the early eighties. i did them with a wild T1A and steel band and a 20kg plumbob.plus an unskilled labourer.
i had to radiate the curves from a chord offset as the centre was unobtainable. i think i used an old hp25 or 35, with the red light display and hand calced as we all did then, no programs.
i think the govt surveyors had the 41 models maybe.
the concrete balconies were a pain to layout on the formwork with the tower crane moving the building at times.
looking back now, i did a good job and smile, it was within 3mm at the top, because i wasnt licenced i had to get another guy in to certify the verticality as the building was designed 20mm off the boundary.i kept his certification statement as proof, plumbobs are hard to beat.
the other building i did before this was the sheraton, now a crowne, soon to be hilton, but with 10 tonne pre cast panels on the top floors.
i am back here 28 years later doing some civil stuff in town, i got 3 speeding tickets in 3 weeks here, funny litle school zones, my first tickets in 15 years oh well
cheers

I have never performed surveying services for a high rise building, and, quite frankly, wouldn't know what to do after the foundation was laid out!

Still remember how to ride a bicycle? 😉
Have a great week! B-)
I don't have nice pictures, but my early years were spent working high rise in and around LA. Also back in the '80's. Developed a bit of height phobia after seeing a few accidents. Luckily I finished the apprenticeship and went on to the larger field of Land Surveying.
Still remember the days of grit between my teeth though....
Very very cool.
thanks
i dont do land work, because i did an aprrenticeship first as a carpenter, then foreman, then back to college for surveying, the construction survey goes hand in hand.
you know what is needed, and give them stuff ahead of when they need it etc.
i remember one job on a sat afternoon, two hp's in my hand, working out a spiral curve for a parapet wall on a curved library, one calc was doing the radiations and the other the elevations, sitting on the roof of the building giving points to the contractors.
i admire you guys on the land and enjoy your posts, i just traverse carparks ha
thanks

Neat story! I'll even add to it....I stayed in that hotel back when it was a Sheraton. 🙂
I know this is an old thread but... do the tower cranes shake the building that much to make a difference?
By the way, is that in Brisbane or somewhere else?
Cool. Very impressive monument to have set.
.... until some jackleg sets a pincushion one right next to it
