The first step is modeling the existing structure. There are several issues with that. The obvious one is guaranteeing 100% accuracy. This is especially important because the owner intends to panelize the interior partitions off site. The potential solution for this will be as follows:
- Model structure to remain from original as-builts
- Field verify the overall geometry of the model; update as needed
- Laser survey the existing conditions; update dimensions/locations of columns in model based on survey; update as needed.
So far, 20 custom columns have been created for the project and the first floor isn't even finished yet.
