SCL History

Systems Consulting, LLC was founded by Gretchen and Everette Adams in 1999. Both have over 20 years' experience with corporate, local, state, and federal agencies. As an executive business manager in the aerospace industry, Everette managed cost performance and quality assurance engineers on NASA, military, and government contracts, while Gretchen worked as a high-tech business and marketing executive. Their primary focus was the establishment of general management consultants that provide a full range of professional services to clients: financial, consulting, administrative, and human resources. With their complementary skills and expertise, Everette and Gretchen established a partnership that has steadily gained a reputation for integrity and excellence.

SCL boasts an extensive project and construction management portfolio. Key to its history is the firm's participation as Quality Assurance Auditor for the Central Puget Sound Regional Transit Authority's (Sound Transit) Capital Projects Program Lifetime Capital Plan and its $7.6 billion regional mass transit system. Impacting rail, facility, roads, bridge, tunnel, bus, train, light rail, commuter rail, signal, and utility systems, this 5-year engagement provided the foundation for the firm's performance on future public transportation and infrastructure projects.

In 2005, SCL partnered with its client and the King County Department of Natural Resources Solid Waste Division during an area closure of the Cedar Hills Landfill. This entry into hazardous and toxic waste management served as a significant turning point for the firm; SCL was now face-to face with new clients, different technologies, diverse professional capabilities, unknown risks and challenges. Ultimately, the challenge paid off. Participation in this award-winning project launched SCL's Waste Management and Wastewater portfolios.

In 2006, SCL would provide cost validation, administrative, utility, and information systems support services for the Washington State Department of Transportation's (WSDOT) $17B dollar Regional Transportation Investment District project. The firm's work impacted over 75 highway, road, and bridge endeavors along the I-5 corridor.

In 2009, SCL returned to Sound Transit to conduct an Independent Assessment of Operations Start-up of the Link Light Rail Initial Segment. As the prime contractor, SCL looked at the complete life cycle of an agency seeking a full funding grant agreement through to the initial segment startup.

In 2010, SCL joined the Denver Transit Partners (DTP) as Quality Assurance Manager on the first public-private partnership for commuter rail in the United States - Regional Transportation District (RTD) FasTracks Eagle P3 in Denver, Colorado. Using the design, build, finance, operate and maintain (DBFOM) delivery method, the project included over 36 miles of electrified commuter rail and 15 stations from the hub at Denver Union Station (DUS) to the Denver International Airport (DIA). The total capital cost of the projected 30-year project was estimated at $2.1 billion. As QA Manager, SCL provided quality oversight and facilitated and obtained the ISO 9001:2008 registration.

Today, SCL continues to deliver outstanding professional services in planning, design and construction management. Whether impacting transportation systems, public works, other infrastructure projects like aviation, SCL continues to expand its operations to new markets while maintaining our role as the standard in project management, controls, and quality oversight.
