Serving Federal Way, WA
Federal Way incorporated on February 28, 1990 and covers about 22 square miles between Seattle and Tacoma in King County. Interstate 5 runs through it at exits 142A and 142B for SR 18, 143 at South 320th Street and 147 at South 272nd Street, with SR 99, SR 161 and SR 509 also inside the city, and the 1 Line reaches Federal Way Downtown Station on 23rd Avenue South. Steel Lake, North Lake, Mirror Lake and Panther Lake sit inside the city, and Dash Point State Park holds 461 acres with 3,301 feet of saltwater shoreline on Puget Sound. Federal Way is not a factory town, and its measurement obligations come from permits and licensure rather than production. Lakehaven Water and Sewer District serves 46,077 connections and 148,809 people and runs the Lakota treatment plant under its own discharge permit, St. Francis Hospital operates 124 licensed beds with diagnostic imaging, 3D mammography and radiation oncology, Federal Way Public Schools runs 41 schools for 22,264 students, and the city maintains a 1,094-acre park system and its own surface water program. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Federal Way sits outside our Mid-Atlantic pickup radius, we serve King County through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointments at your facility. Each calibration is performed against documented procedures, traced through NIST, and accompanied by an audit-ready certificate that supports AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820 quality systems.
