Value Assist Fabrication

Getting the design right from the start sets every project up for success. When Rainier Welding is brought in early, costly field fixes, redesigns, and “what were they thinking?” moments are avoided. Early collaboration helps streamline decisions, reduce risk, and keep the project moving efficiently.

- Value Assist Fabrication and Value Engineering play a key role in lowering labor costs and minimizing transportation expenses.

Efficient installation

We focus on creating a smarter workflow that reduces delays and keeps installation running efficiently.

- Minimize on-site man-hours and complexity
- Solve problems in the design – before fabrication, before field installation
- Maximize local labor fore productivity

Cost effective direct transportation

By shipping from Northwest Washington State, we deliver a cost-effective logistics path that includes:

- Heavy-haul road access
- Direct barge load-out capability
