What's included: Building package (metal building kit) + steel erection + concrete/site work. All figures are per square foot, based on national averages.

What's not included: Land, permits, utilities, design fees, financing, landscaping, or other soft costs. ROI does not perform concrete services — concrete figures are based on national averages for reference.

Note: Actual costs vary by location, zoning, wind loads, snow loads, and current steel market. Flex space pricing ($16+) increases with finish level and specialization. Request a quote for your specific project.

As a repeat customer, Puri-T Welding & Fabrication in Richland, WA rely heavily on dependable suppliers, and this team at ROI continues to deliver. We've had the pleasure of working with Lisa, who has been great—always responsive, organized, and easy to work with. Communication has been consistent, turnaround times are solid, and the metal building packages arrive accurate and complete.

We had a great experience with ROI in putting up some new storage units. The buildings were erected within 3 months from our first conversation. Dave and the team were prompt in answering any questions. They also assisted us in finding a crew to install who completed the whole install in 4 days during the bitter cold of January. We will use them again.

I had ROI provide the steel building for a new hangar installation. Dave was great to work with and made navigating the options easy. Price-wise it was definitely the best value for the dollar spent. I had a custom opening for a hangar door and their engineers accommodated the special request.

Working with Dave & ROI was a great experience for me. Everything was just as Dave described and my involvement was very limited which suited me fine. Building was delivered promptly & the crew that erected building was very professional also. If I were to build again I would definitely contact Dave & ROI.

I worked with Dave on my storage facility project that included 2 buildings with 120 new units next to our older facility. The service level and attention to detail was much appreciated. We went through two other building manufacturers prior to working with Dave Maxe. Needless to say the two other manufacturers dropped the ball, which cost us thousands of dollars in expenses and lost potential revenue. Dave job well done. Thank you.

Lisa Wirth is the most straightforward and knowledgeable professional I have ever worked with in the metal building industry. Her candid approach from design to delivery, and attention to detail, saved us tens of thousands of dollars. I've vetted dozens of suppliers and consider her the best choice.
