If you consider my additions worthy, then I would say so, yes. The top floor is at +100 z's.
I'm not sure how well my journal fits in with the rest of the players' continuity, but it includes a rather humorous construction mishap that actually happened:
----
Annoyed that their 100-story monument to Dwarvenkind had been sitting just near completion for too long, the Dwarven council (during one of the scant minutes of the day they weren't completely drunk) ordered me to go finish the last four levels of the monument and to check on King Likotbecor, whom they hadn't heard from in ages. I arrived to find that there are currently just over 200 dwarves living and working here, and the total created wealth is rumored to be nearing ten million dwarfbucks. I immediately went to the top story and got to work.
20th Moonstone, 1071 - While finishing the green glass flooring on the 96th floor, a misplaced block of glass flooring came loose, crashing through the two floors below (one of which was part of a stockpile), and falling another 15 stories right onto Shem Tamolstakud's head. Miraculously, the child survived! However, the 10 other blocks and three solid gold bars that fell from the hole in the stockpile crushed him to a bony pulp, scattering his body parts across 14 floors. At least it wasn't someone who actually did work.
2nd Obsidian, 1071 - While overseeing the completion of the wall on the 94th floor, a dwarf came staggering up to me, panting, yelling about how the lower floors were flooding. Earlier I had ordered the shutdown of the generator, as neither pump stack was currently being used. However, the lever I had found marked "Stops the generator" in the control room actually in fact unleashed a massive flood! Dwarves were cleaning up barrels of food and supplies for days once we had the water under control.
9th Obsidian, 1071 - An Ettin came rampaging into the area today! I immediately ordered our no-doubt well-skilled, impressive, heavily armed... what? We have no army? The lookout who informed me of our pathetic military state also informed me that King Likotbecor refuses to let them bear arms in fear of any sort of uprising. I went storming to his chamber to yell at him, but he refused to even see me. I had yet to check on the King for the council. Fortunately, while I was ragebashing my fists on the King's door, the stupid Ettin fell into a simple cage trap. It appears we are safe for now.
6th Granite, 1072 - The Dwarves finished the green glass walls, flooring, and stone support columns on the 94th, 95th, and 96th floor. I left the 94th floor as a stock room, and designated the 96th as a slab graveyard. The graveyard will come in handy then the final two floors are finished...
20th Galena, 1072 - The gold and clear glass observation room/statue garden on the 97th and 98th floor are completed. All that's left is to finish the top two floors, which are already well under construction and using copious amounts of solid gold.
1st Limestone, 1072 - Today our bookkeeper informed me that the tower had officially passed ten million dwarfbucks of created wealth! The council will be happy to hear about this.
15th Felsite, 1073 - Today the final floor of the tower was completed! The top floor is an altar to the glorious Armok, and several of the denizens of this tower were more than happy to offer themselves as the initial sacrifices to the blood god. After months of attaching mechanisms to spikes, the altar finally boasts a fully functioning sacrificial spike pit, ringed with 30 golden statues. Tonight I return to the council to report the successful completion of the tower, despite being unable to find any information about the King.
