Building the Data Warehouse for Project Replication

The code in lesson 2 of the LLMOPS short course uses an existing BigQuery Data Warehouse to access the Q&A data used for data preparation. If we are interested in replicating this project in our GCP environment, we would need the logic to build this Data Warehouse in GCP and populate it with the Stack Overflow Q&A data. Is there a way to access the required code / logic to do this? Is there an online resource / tutorial etc that would help?

Thanks in advance
