Soldier Field Land Surveys

While Gremley and Biedermann did the initial boundary and Topographic survey, James Schaeffer and Schimming were contracted to layout almost all aspects of the project. From column line control to grade staking, James Schaeffer and Schimming had their hands in every piece of the construction layout process. Since Soldiers Field needed to be completed in a hurry, our crews worked 24 hrs a day to complete the task on time

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.
