Trump Tower Land Surveys
Trump Tower — Chicago, IL — PLCS Corporation

Since 1930 Chicago Guarantee Survey has been preparing plats of survey for the Old Chicago Sun Times building. As you may know that building was demolished to make way for Trump Tower. All three of our companies have had a hand in the creation of the tower. Chicago Guarantee did the original Plat of Survey before construction started. James Schaeffer and Schimming worked on various layout and quality control tasks. Gremley and Biedermann then prepared the air rights division separating the commercial, residential and hotel parcels.The body content of your post goes here.

This one seems kind of overwhelming at first. The pages are so battered and torn that it is hard to decipher some of what is going on.

I believe this survey to be done by Eckstein for Stein and Baumgarth of lot 8 in Nutts subdivision of lots 1,2, and 3 in block 64 of a subdivision of the Southwest quarter of section 21-39-14.

Jackson and Hermitage January 8,1881

Here we see a survey done of lot one in block 3 in Ashland addition to Chicago, being a re subdivision of the overall Chicago subdivision. This survey seems to also require a vertical component in the Chicago City Vertical Datum system. I am sure I will cover more on CCD, or Chicago City Datum, in later posts as they arise.

U505 Submarine Land Surveys

Being one of the most unique looking buildings in Chicago, the Aqua was a challenging project. Gremley and Biedermann provided our client with an air rights division that separated the condominiums, the apartments, the commercial and the hotel parcels horizontally and vertically. The four were then presented in a three dimensional depiction so that the client had a better vision of what is taking place.
