English to Arabic Bus/Financial Business/Commerce (general) Abbreviations

It's a subcontract agreement, in the recitals part.

Whereas the contractor has entered into a contract (hereinafter called "the Contract") with M/s XYZ, for the construction, completion and maintenance of a commercial complex at Shk. Zayed City, Sector ME-(No.), Plot No. C-(No.).

In the very beginning, a company was given the following address:
M - 09, Building name, Street name

Hope this is enough for the context, though not for the meaning. Common abbreviations links online might not help to figure out the ingenuity of such address codes given in UAE.

I will leave "C" as it is, and possibly the rest if there is no clear meaning for such words.
