Welcome to JTS

JTS provides project controls and construction management resources for public infrastructure design and construction projects in the greater Puget Sound region. Based in Seattle, Washington, JTS has served the region since 1993.

JTS has a variety of services to support project managers on projects using project controls, document controls, contract administration, and resident engineering. Our areas of expertise include mass transit, tunneling, transportation, water/wastewater and transit/transportation sound mitigation. JTS is a small, minority-owned business. Our size is often our advantage; without the constraints of a large organization, we are flexible enough to work within the parameters and dynamics of any project.
