The 5 Mega-Projects Powering Mass Electric Construction Co.'s $1 Billion Dominance In 2025
Mass Electric Construction Co. (MEC), a premier electrical contractor and a subsidiary of the global powerhouse Kiewit Corporation, is currently solidifying its position as a dominant force in North American infrastructure with a slate of major, highly technical projects stretching well into 2025 and beyond. As of December 2025, the company is actively engaged in critical system construction for major transit authorities and complex industrial facilities, leveraging its nearly century-long expertise in large-scale electrical and systems integration. The firm’s strategic focus on transit, rail, and emerging power markets, particularly Electric Vehicle (EV) Infrastructure, has positioned it at the forefront of the continent’s most ambitious public works initiatives.
The company’s recent activities, including significant contract awards and modifications in 2024, underscore its commitment to delivering complex, mission-critical electrical and systems solutions. From high-voltage traction power systems for light rail extensions to sophisticated control and communications networks, MEC’s current portfolio reflects a deep specialization that few competitors can match. This deep dive explores the company's profile, its foundational history, and the five mega-projects currently defining its financial and operational landscape.
Mass Electric Construction Co. (MEC) Company Profile and Foundational History
Mass. Electric Construction Co. (MEC) is one of the leading electrical contractors in the United States, specializing in large-scale electrical construction, design, and maintenance services. The company is renowned for its work in the transit and rail, power and energy, and industrial sectors.
- Founded: 1928
- Founder: Francis Angino, a 23-year-old entrepreneurial electrical engineer.
- Headquarters: Originally established in Massachusetts.
- Parent Company: Kiewit Corporation (MEC operates as a key subsidiary).
- Core Services: Electrical Construction, Systems Design & Integration, Maintenance, Traction Electrification, Train Control/Signals, Communications, Highway & ITS, and Electric Vehicle Infrastructure.
- Geographic Reach: Nationwide presence across North America.
Founded in 1928, MEC quickly established a reputation for tackling complex electrical challenges. Its long history has seen it evolve from a regional contractor into a national leader, particularly after becoming a subsidiary of Kiewit, which provided vast construction and engineering resources. Today, MEC is virtually synonymous with major transit and rail systems installation, having worked with nearly every major transit authority in the United States.
MEC's Strategic Focus: Dominating Transit and Emerging Energy
MEC's market strategy is clearly defined by its expertise in two primary areas: complex transportation systems and large-scale industrial/energy projects. This dual focus allows the company to capitalize on massive governmental infrastructure spending and the rapid transition toward renewable and electric power.
The Pillar of Transit and Rail Systems
The company is a recognized leader in the installation of complete transit and rail systems. Their work in this sector goes far beyond simple wiring, encompassing specialized fields that are critical to modern urban mobility. These key specialties form the backbone of their transit work:
- Traction Electrification: The installation of the overhead catenary systems (OCS) and substations necessary to power electric trains and light rail vehicles.
- Train Control/Signals: Implementing the sophisticated signaling and control systems that ensure safe and efficient rail operations.
- Communications: Designing and installing the vital communication networks—including fiber optics, radio systems, and public address—that link the entire transit system.
- Highway & ITS: Extending their expertise to Intelligent Transportation Systems (ITS) and electrical work for major highway projects, such as the lighting and electrical upgrades for the Arlington Memorial Bridge Rehabilitation.
MEC’s extensive experience with clients like Sound Transit, TriMet, and Valley Metro demonstrates their deep integration into the nation’s largest public transit expansions.
The Rise of Electric Vehicle (EV) Infrastructure
In a forward-looking move, MEC has strategically positioned itself to handle the high-powered electrical demands of the rapidly expanding Electric Vehicle (EV) Infrastructure market. This includes specializing in the construction of high-powered charging stations and the necessary utility upgrades to support large-scale fleet electrification. This new market segment leverages their core competency in large-scale power distribution and industrial electrical solutions.
5 Mega-Projects Defining Mass Electric Construction Co. in 2024-2025
The following projects and contract activities, many dating from 2024 and extending into 2025, highlight MEC's current operational focus and financial strength:
1. Sound Transit East Link Systems Construction (Seattle, WA)
This is arguably MEC's most prominent current transit project. MEC was awarded the East Link Systems Construction contract, a critical component of the expansion of Seattle's light rail system. The work involves the complex integration of all operating systems—including traction power, signals, and communications—for the new extension into the Northgate area. Contract modifications and status reports from Sound Transit in 2024 and April 2025 confirm MEC's ongoing, central role as the E750 Contractor for this massive regional infrastructure investment.
2. TriMet Construction Manager/General Contractor (CM/GC) Services (Portland, OR)
In a significant contract announcement from June 2024, MEC was selected by TriMet to execute a Construction Manager/General Contractor (CM/GC) Services contract. This award demonstrates a high level of trust from a major transit authority, allowing MEC to oversee and manage construction services, likely related to future rail or system upgrades within the Portland metropolitan area. This type of contract is indicative of MEC's shift toward more comprehensive project management roles.
3. Rodeo Renewable Fuels Facility (California)
As part of Kiewit’s broader energy portfolio, MEC is involved in the construction of the Rodeo Renewable Fuels Facility. MEC's scope includes the construction of new facilities dedicated to renewable feedstocks handling and pre-treatment systems. This project showcases the company’s ability to pivot its industrial electrical expertise to the burgeoning renewable energy sector, ensuring the complex electrical infrastructure needed for sustainable fuel production is correctly installed.
4. Bitter Point Pump Station Replacement (Water/Wastewater Infrastructure)
Working in a joint venture with Kiewit, MEC was tasked with replacing an existing sewage pump station with a new, upsized 39 MGD (Million Gallons Per Day) facility at the Bitter Point Pump Station. While not a rail project, this highlights MEC's proficiency in large-scale public utility and facilities projects, where reliable, high-capacity electrical systems are paramount to critical infrastructure operations.
5. WMATA Yellow Line and Valley Metro Light Rail Projects
MEC maintains a continuous presence in major metropolitan transit systems across the country. Their work includes the WMATA Yellow Line (Washington Metropolitan Area Transit Authority) and ongoing involvement in the expansion of the Valley Metro light rail system in Northwest Phoenix. The Phoenix project, in particular, involved complex staging and tie-in plans, demonstrating MEC’s specialized engineering approach to integrating new rail segments into existing, operational systems.
The Future of MEC: Beyond the Rails
As Mass Electric Construction Co. moves into 2026, its trajectory is set by the convergence of national infrastructure needs and the energy transition. The company's deep bench of technical expertise in traction electrification and train control systems guarantees its role in future high-speed rail and urban light rail expansions, such as the potential contract awards in mid-2025 related to the Greater Dayton RTA.
Furthermore, the strategic focus on Electric Vehicle Infrastructure and renewable fuel facilities positions MEC to capture a significant share of the non-transit electrical construction market. By maintaining its commitment to safety and leveraging the vast resources of the Kiewit Corporation, Mass Electric Construction Co. remains an indispensable partner in building the electrified future of North America.
