Not to be contradictory here but there are building systems that need precision.
I'm currently managing a site with a complex structural steel frame and the anchor bolts/ embed plates have to he bang on as cast into concrete. Tolerances within our spec are 1/8" in any direction.
This is generally accomplished through professional surveying. In theory, competent execution will give good results. I am frustrated to report that surveyor on this job made a mess out their work, it is demonstrably incorrect, and as a result expensive change orders have had to go to our steel fabricator to adjust connections at base.
TLDR, accuracy is possible; but it my opinion that when all is said and done, construction boils down to cavemen banging sticks and rocks together and you get what you pay for.
