The engineers at Three I Engineering have many years of experience in structural design work including all kinds of building structures, foundations, and equipment supports. There is a good chance that whatever you need to have designed has been designed by one of our engineers and is in use by someone at the present time.

Our engineers have designed structures for our customers throughout this country and in some foreign countries like China, Korea, Mexico, and Taiwan, Our customers include plastics manufacturers, hospitals, pharmaceutical manufacturers, industrial equipment manufacturers, heavy construction companies, and governmental agencies.

Our structural design work has been as diversified as designing panels made from sheet metal to designing a foundation to support two vessels weighing a total of over 340 tons. We have designed contractors equipment to work on Hoover Dam, foundations for power line transmission towers, and over head cranes to unload river barges. We also spend many hours doing everyday design work like designing industrial buildings, designing supports for fans, and designing reinforcing for existing structures to support new equipment.

St. Mary's Medical Center, Medical Office Building - West	A list of our past designs includes the following:
	Industrial Buildings Bridge Cranes Gantries Monorails Jib Cranes Platforms Concrete Silos Steel Storage Bins Elevated Storage Bins Underground Tanks Dip Tanks Office Buildings Earthquake Resistant Designs Utility Tunnels Wood Trusses Aluminum Structures Steel Stacks	Spread Footings Wood Piling Footings Steel Piling Footings Mat Foundations Retaining Walls Reinforced Masonry Walls Concrete Pits Pipe Racks Equipment Foundations Breeching Supports Process Vessel Supports Coal Loading Towers Sheet Pile Walls Steel Trusses Aluminum Bins Aluminum Tanks Breaching

At Three I Engineering we combine the latest scientific tools with engineering judgment. We use computer and CAD programs to calculate stresses, distances, and deflections; and then blend the calculations with our years of experience in designing details and connections to design structures that are safe and economical.
