I cannot create a summary of the requested article because it is not found in the search results provided. The search results include information about Johnson & Johnson from other sources - including talc and asbestos lawsuits, pharmaceutical company acquisitions and other cases - but do not include the article titled "J&J to build $1bn US CGT manufacturing site in Pennsylvania". In order to create an accurate and factual summary as per your requirements, I would need access to the original article.
