CSI Puget Sound Chapter Membership

Why join CSI?

If you're an architect, specifier, product representative, contractor, or any other kind of construction professional, and you want to know more than your piece of a project, join CSI!

CSI members have an in-depth understanding of construction because what they know goes beyond their job. They spend time with professionals from other fields and learn how they fit with the rest of the building team. They are experts in the process of identifying real-world building product solutions, communicating those solutions in construction documents, and ensuring that all the members of the construction team are building the facility the owner wants and is paying for. Their employers benefit from their ability to see everyone's role in a project. CSI members deliver!

Remember to check "Puget Sound" to join our chapter!  Membership form link is HERE.
