Massive boulders, shipped from as far away as the Northwest Territories, echo the curvaceous form of the museum building, its rough-hewn limestone surface meant to recall a cliff face sculptured by the wind. (From ACT TEST)
Why is "meant" used here? I don't think here it is a past tense because there will be two independent clauses not connected by conjunctions; so the only possible option left is past participle, but why not use present participle "meaning"?
