English to Spanish Tech/Engineering International Org/Dev/Coop

I am translating a document on refugee camps and I am using the word "terreno" or "lugar" depending on the context; (i.e. selection, site layout, site preparation, site management, etc).
But I would like to find the exact term in Spanish, if any. I have seen it being translated as "sitio". Parece una traducción literal, pero quizás me equivoque.
