Rex Moore Production System

A Lean system that is integral to the way we do business.

Rex Moore is at the forefront of the electrical construction industry in large part due to its successful adaptation of Lean manufacturing methods and processes to the electrical construction industry, creating the Rex Moore Production System (RMPS).

With RMPS, Rex Moore deploys standardized designs and prefabricated assemblies, coupled with a specialized point of use packaging, to provide unmatched value to its clients. The RMPS is proven to minimize re-work, reduce material lead times, improve quality, shorten schedule durations and improve safety.



All projects are Designed for Manufacture, Assembly, and Installation (DFMAI). DFMAI improves construction pre-planning and drives standardization into all of our products and services, thereby providing the opportunity to achieve higher levels of efficiency and cost savings



Standard assemblies allow for mass production in a flexible Lean manufacturing environment, including standardizing materials that allow for large bulk buys for all company projects, thereby reducing costs and lead-times


Standardized methods allow for a standardized Work Breakdown Structure, consisting of groups of work packages within a project, called “Kits”


Kits contain drawings, tools, materials and mass-produced manufactured assemblies for installation. Kits are fundamental to electrical and low voltage construction efficiency because


Kits allow for efficient field installation and reduced material handling, storage, and trash


Kits facilitate effective scheduling based on workflow and reduce task durations, resulting in completion of work in less time compared to conventional construction methods.


A record that is consistently one of the best in the industry.
Rex Moore has developed many innovative safety and risk management programs that exceed both Federal and State standards while realizing that employee commitment to a safe and healthy workforce is what makes our programs work.

The Rex Moore Production System incorporates a process in which each installation and manufacturing task is analyzed for risk exposure during the design phase. As a result, a Job Hazard Analysis is created during the Kit Detailing Process and follows the Kit through completion in the field. This process alerts the team to pre-plan and mitigate potential job hazards. The JHA creates early awareness and improves planning and communication of remaining hazards on-site, dramatically reducing employees’ exposure to harm.

Rex Moore’s systems, culture, and people combine to attain one of the lowest loss records of any contractor in the industry.
