About Us

Systems Consulting, LLC (SCL) is a professional services firm dedicated to improving how public infrastructure is delivered. We provide engineering, project management and consulting services to government agencies and private-sector partners in the public transportation and environmental sectors. From quality oversight project controls to staff augmentation, SCL offers the support that agencies and engineering firms seek to successfully deliver complex programs. Since our founding, we have completed over 200 projects spanning design-build ventures, public-private partnerships (P3), and traditional construction management contracts. Every project we undertake is driven by our commitment to excellence, innovation, collaboration and the belief that better project delivery leads to stronger, more sustainable communities.

Our story

SCL was founded in 1999 by Gretchen and Everette Adams as a response to a growing demand for 21st century innovation in capital program and project delivery. Customers were seeking tools and support to help operate, manage and deliver large capital programs on time and on budget. Today, working closely with our clients and industry partners, our project portfolio spans 25 years of project controls to produce the results they were after.

In 2001, we performed services for King County (KC) alongside their Department of Natural Resources Solid Waste Division. During an area closure of the Cedar Hills Landfill, this contract posed new demands as we faced different technologies and experiences. But the results of this award-winning project paid off, proving to be an accomplishment for SCL as it established us in the water and wastewater treatment markets. As a result of our team’s efforts to deliver reliable results, KC extended our contract from a 4-year to a 12-year term.

Soon after our founding, we partnered with Sound Transit as a Quality Assurance Auditor for a $7.6 billion regional mass transit project, the Capital Projects Program Lifetime Capital Plan, in 2002. Our work entailed audits to verify that the project elements were acceptable, developed, documented, and implemented across its progress. We have since forged a long-term successful relationship with Sound Transit and continue to support them as their needs evolve.

Eventually, our projects broadened our reach outside the Washington market, and we built a strategic partnership with the Regional Transit District (RTD) in Denver, Colorado. Serving as Quality Assurance Manager for RTD, we joined the first P3 for commuter rail in the US during the FasTracks Eagle project in 2010, valued at over $2.3 billion. This project included over 36 miles of commuter rail and 15 stations from the Denver International Airport to downtown Denver Union Station. In our role, we established the first team with a Design-Build-Finance-Operate-Maintain (DBFOM) delivery methodology to register with ISO 9001:2008.


Continuing our expansion, we began to work in Los Angeles, California, alongside LA Metro. After completing the Little Tokyo/Arts District Station successfully in 2016, Metro granted further responsibility to us to provide program-wide quality management for trains, busses, and more on several upcoming large capital projects that continue to this day.

As we expand our markets and capabilities, we advocate for agencies and the communities they serve. Through close collaboration, we enhance the scope of work, build capacity, and deliver reliable project management, controls, and quality oversight. Over 90% of our clients have grown to expect the same dependability to work with them on their next endeavor.

OUR VISION FORWARD

SCL continues to advance public infrastructure through project delivery by working with agencies, clients, and communities. We will leverage best practices to face new challenges with emerging technologies through imagination and a commitment to leave a sustainable impact. Ultimately, we hope to improve the health and safety of the places where people live, work, and play so that communities can thrive.
