What are the general paid holidays for construction workers in Texas? Or are there any?

Whatever the employer choose to offer. Regardless of what state you are in or what industry you work for, if you are in the private sector there are NO holidays that your employer is required to offer.

I understand that, but is there kind of a standard for Construction Holidays? I know they do not observe every Federal holiday, but I'm trying to get an idea of what holidays are paid by construction companies.

It depends on the construction company.
