Geiger Brothers has key role in building dry air and nitrogen complex

Dry Air Plant Steel

Under contract to CDM Smith, Inc., and in doing “fast-track” construction, Geiger Brothers recently was responsible for pipe support and pipe spool fabrication and installation, concrete pours, earthwork, and underground system installations for new facilities on the U. S. Department of Energy’s (DOE) reservation in Pike County, Ohio.

The design-build contract for the $6.2 million X-670 Dry Air Plant, X-670A Cooling Tower and X-675 Nitrogen Station complex was completed within less than four months. The fast-track was required to move functionality of existing plant air and nitrogen systems from one of the large site uranium enrichment process buildings to enable DOE turnover of the building to the site decontamination and decommissioning (D&D) contractor.

To meet the deadlines Geiger Brothers used Primavera P6 CPM Scheduling software and lean construction techniques, and placed an extraordinary effort on pre-fabrication of components in its shop at Jackson, just 30 minutes from the project site. Geiger Brothers implemented just-in-time delivery of fabricated plumbing, piping and HVAC components working multiple shifts in a 24/7 environment to complete and commission project systems.

Dry Air Plant Night Pours

More than 4,800 code ASME B31.3 Process Piping and B31.1 Power Piping welds were completed for the air, cooling water, nitrogen, steam, natural gas, condensate and boiler blowdown and auxiliary system piping.

Geiger Brothers and designers from CDM Smith utilized virtual and BIM techniques to coordinate the placement of equipment, vessels and heavy piping and electrical components within the building structure.

More than two miles of 18-inch aboveground cooling water lines and structural supports and bridges previously had been installed to link the new dry air plant compressors and nitrogen plant from throughout the DOE reservation.
