ACInsider Year in Review 2023

Now that we’re well into the start of the New Year, we can finally take a moment to catch our collective breath and reflect a bit on the very good year that was 2023.

ACI continued our growth trajectory that we had set about in the post-pandemic year of 2022; projects, geographic reach, and number of employees are all on the rise. Our backlog of jobs is solid, our reach has now expanded confidently into Northern Virginia and Wilmington, North Carolina, and our employee count has grown to well above 1150. Our offices in Roanoke and Hampton Roads are experiencing steady growth as they carry the ACI Mission in Western and Southeastern Virginia and at home here in Richmond, construction of our new facility (HQ2, as we refer to it these days) is moving along on schedule (feel free to take a look HERE).

Below, we invite you to explore a handful of achievements that made us proud in 2023, projects that were thoroughly imbued with the ACI Mission to be EXTRAORDINARY, through Innovation, Collaboration, and Diversity. We hope the year just passed was a good one for you, and we invite you to join with us in this New Year and as we work to make it a great one!

Confidential Modular Pipe Rack Project

Atlantic Modular Steps Up

About this Project

Realizing that ACI was uniquely well-positioned to take on very large, complex modular projects, one of our partnering firms engaged us to assist in building 61 modular units of pipe racks for one of the highest profile clients/companies in North America.

With a very challenging schedule to meet, work started on the contract (valued at just under $6M) just after Thanksgiving and was completed by the start of the last week of January, which made it just shy of an 8-week turnaround. Systems on the racks were: Electrical, Chilled Water, Natural Gas, Domestic Water, Compressed Air, Non-potable Water, and Steam.

– Fabrication & erection of 277 tons of steel.
– Installation of 11,000 feet of pipe
– Coordination of outside insulation & electrical crews to install to form a multi trade rack.
– Shipment to Tennessee

In the time-lapse video below, you can see 18 days of the process compressed into 38 seconds:
