Our project progress is too slow, so we want to send it to the engineering teams by SMS to urge them to hurry up. . How should I write it well

you must not be too polite to send a text message to the construction team, and you must not write too luxuriously. It can be written as follows:

In order for the project department to achieve the progress goal. The main purpose is to let others know that you are a team with great strength and can seize the construction period, so as to prove that you are outstanding among many teams. You must complete ... (project plan) this month. Of course, safety and quality are still the first in the construction process.

you can also add something of your own to it. It's just an idea. I wish you a rising career. Become a project manager as soon as possible.
