ConclusionConclusion

Efficiency– Our structure uses an intelligent moment frame

design coupled with a smart open webbed joist floor system.

Economical– This will minimize material cost, saving money.

The quick erection time shall reduce capital cost. Elegance

– Our Armory will maintain the authenticity of its historic fortress like appearance, and the New Building shall complement the aesthetic mastery of the Armory.
