Company History


Our history is rich with innovation and deep construction expertise—it’s a history of success that powers our future.


RMT, Inc. is founded. The early corporate plan for RMT was to provide industrial clients with full- service waste management and groundwater quality consulting services—from conceptual regulatory permitting to investigation, design, construction engineering, and monitoring.


RMT formalizes its Construction Services unit and executes its first turnkey construction project


RMT’s energy business unit is acquired by Infrastructure and Energy Alternatives, Inc. (IEA).


RMT is renamed and rebranded to become IEA Renewable Energy.


IEA (corporate) realigns the organization and approach to executing contracts. As a result, IEA Renewable Energy’s average contract doubles in size and annual construction increases from an average of 500 MW installed per year to over 1,100 MW.


IEA Renewable Energy is renamed and rebranded to become IEA Constructors to expand our service offerings beyond the namesake of “renewable energy.”


IEA and its affiliated companies were acquired by MasTec and are now part of the organization's Clean Energy and Infrastructure segment.
