Strømmen

I am writing this post only in order to reassure my geodeta friends and acquaintances about that's not better elsewhere.
Well, today I could do a nice overtime again. Now it was because of the reconstruction of the train station mentioned in the title. At our company everybody call the construction leader there Cowboy. Now I could have experienced personally that this name fits to him. The method is quite usual at home as well; when he see that the surveyors are packing together and are about to leave after finishing the job he gave by 7 pm he just call us back and make us to set out some heights for him. In addition he also could have measure those heights if he would.

Today I saw the road runner program during usage. By this program you can set out points wherever you want in any kind of line, curve, arc and complex line in 3D. By using a loaded DTM wherever I move the reflector the planned height at that point appears immediately so I can set out the height wherever the costumer wants to have it.
For we work with Leica TCRP 1203 robotic theodolites which follow the reflector (if it can see it, but a construction is not really the place where isn't anything on the direction) and I can control the instrument from the distance by the controller fixed on the pole and at the same time I can see how far I am from the point I want to set out. The free station is ready in a moment thank reflectors fixed upon buildings nearby...
Than, why the hell took setting out 40-50 points 8 hours for two people? Well, on one hand because we had to control dates from the paper plan since DTM is not valid everywhere, on the other hand because of the marking. The one and a half meter long wooden stick doesn't go down in rolled down gravelled surface. There wasn't shorter one, we have run of all the half meter long sticks recently however there was a full pallet. Have somebody to cut iron is heresy here. I had to seeking some waist irons. There is not simple to drive into earth 1,5m long 16mm diameters concrete-ocel neither, though as one machine controller guy demonstrated with a 5 kg hammer: "It's possible! So I have learned something today again... on the hard way of my engineer career.
