Here’s a comment from another article linked in the OP to give another side to the story:
“I have intimate knowledge of this project from the beginning. There are multiple causes for this project being behind schedule and over budget. They all stem from TSMC themselves.
First, TSMC and their engineers are absolutely clueless about building to meet U.S. code. Within 8 weeks of the project starting, they were firing the Tiawan based engineers because they were clueless and could not communicate with the U.S. based partners.
Second, they are behind schedule because THEY OWE HUNDREDS OF MILLIONS OF DOLLARS TO SUBCONTRACTORS AND ARE NOT PAYING. Yes, HUNDREDS of MILLIONS. Contractors have stopped work because they have not been paid. No wonder they want to bring in out of country labor. They won't have to worry about paying anybody. I literally have been told "this is not how we do it in Taiwan. We just settle up at the end of the project."
This should be an insult and slap in the face to all U.S. taxpayers, not just the contractors and workers who are being taken advantage of by TSMC and our local officials who are supporting them and their actions. Yes, Mayor Gallego, Senator Sinema, Senator Kelly I am calling you out. Keep telling everyone how great a deal this is for us. So TSMC wants $50 billion from U.S. tax payers, they don't want to pay hundreds of millions of dollars to contractors who have done work, and now they want to bring in their cheap slave labor so they can circumvent the work stoppage by contractors they wont pay. Everything I said is true and verifiable.”

Reminds me of the movie Gung Ho where the Japanese are trying to build cars in 80's America.
At the same time, Japan's TSMC fab (JASM), building is on schedule and don't see such problems. Maybe lower salary and similar work culture contribute flawless building.
From what I hear, they are being extremely tight with their budget, while simultaneously demanding aggressive timelines. These things are for the most part, mutually exclusive.
