Controlled shops, predictable outcomes.
Some of our most important work doesn’t start on a jobsite. More work is moving from the field into advanced fabrication environments where quality, safety and consistency can be controlled long before installation begins.
RK has invested in advanced fabrication facilities, specialized equipment and a highly skilled workforce to engineer, fabricate, assemble and test increasingly complex building systems. By fabricating in controlled environments, we help customers improve quality, reduce field labor, increase schedule predictability and accelerate project delivery.
From mechanical and process piping systems to structural steel assemblies, large-scale pipe racks, skidded systems and engineered infrastructure solutions, every product is designed for constructability, fabricated with precision and delivered ready for efficient installation in the field.
How prefabrication works
Engineer
Safety planning and quality control are built into every phase, not added at the end.
Build
in the shop
Products and systems are fabricated, tested and quality-checked in a controlled environment.
Deliver
& set
Finished assemblies arrive sequenced and ready to install in the field.
Speed
Work runs parallel to site activity.
Quality
Shop conditions, repeatable results.
Efficiency
Less waste, fewer field hours.
