We Partner with You for Fab Construction Services, High-Purity Facility Buildouts, and Equipment Needs

Foresight On-Site is not just another subcontractor; we are your partner for fab construction services—helping teams deliver high-purity DI and chemical systems safely, consistently, and on schedule. We specialize in hi purity and chemical piping for critical processes, from tool hook-ups to factory-wide distribution. We only take on jobs where we can provide high value to our customers. As a licensed and bonded C4 licensed piping (pipefitting) subcontractor, we bring the field experience and rigor your project requires.

Our value-add is rooted in best-in-class execution for fab chemical containment and Chips Act process piping—so you can scale faster while protecting people, tools, and uptime.

  • High-Purity Plumbing: We support the installation of all high-purity plumbing, including hi purity and related chemical piping for critical distribution and point-of-use connections. We operate the latest George Fisher Pure Bonding machines and KITZ for specialized PFA fusion bonding.
  • Plastic Containment Structures: We deliver liners, tool containment, and entire factory containment as part of comprehensive fab chemical containment programs—designed to integrate cleanly with adjacent piping runs (including double containment piping where required). With over 100 CERTIFIED plastic welders, we are the largest provider of welding services in the US.
  • Tool Install: We support semiconductor tool installation with the final hookup of chemistries—coordinating chemical piping, hi purity piping, and verification activities to align with CHIPS Act process piping requirements and commissioning schedules.
  • Water and Wastewater Systems: We have significant experience in single- and double-containment plumbing, including double containment piping for water systems where segregation, leak detection, and safety are paramount—installed under our C4 licensed piping scope.
  • Chemical Equipment: We support the production of low- to mid-complexity plastic valve manifold boxes (VMBs), chemical delivery systems, and other high-purity systems—engineered to interface cleanly with chemical piping, hi purity piping, and fab chemical containment expectations where speed and cost are key factors.
  • Turnkey Partner: We are unique in our ability to build chemical equipment, install factory-wide plumbing, install and hook up equipment, and help you get it qualified—bringing together fab construction services, CHIPS Act process piping, and rigorous containment practices under one team.

  • CNC Machining: With over 60 of the most advanced CNC machines, we can quickly make anything you need to keep fab construction moving. 17 CNC routers running 24/7 produce chemical cabinets, enclosures, and fab chemical containment components in a fraction of the time of other companies, with perfect fits.
  • Plastic Welding: Our plastic welders are certified to AWS B2.4 to ensure consistency and quality, an advantage no other company offers. We have also developed custom controllers that eliminate variables in the weld process, ensuring welds are always consistent and leak-proof—critical for fab chemical containment assemblies and interfaces to double-containment piping systems.
    • Proof Point: Six top plastic welders from one of the largest semiconductor fabs evaluated our capabilities in 2024, at the end of the meeting they agreed, “I wish we welded like this.”
  • High Purity Plumbing: We have more than 20 full-time staff who do nothing but produce high-purity interconnects for critical purity applications. We are true experts in hi purity and chemical piping, including PFA connections, PFA compression fittings, and fully automated pure bonding of chemical plumbing using George Fisher 63 and 110 automated systems—supporting demanding process piping specifications.
  • Chemical Systems: We build 1000+ chemical systems annually that are thoroughly tested and ready for installation, supporting fast-turn fab construction services. Our systems are designed to integrate with fab chemical containment approaches and connect cleanly to chemical piping distribution systems in nearly every leading semiconductor fab worldwide.
  • Clean Room Options: Depending on the state of your construction project, we have extensive cleanroom integration operations and can provide Certified Clean, Cleanroom-Packaged, or help staff on-site clean room install applications—especially where semiconductor tool installation schedules and high-purity hookups are critical.
