Three Ways to Work
with Spans
Whether you need a complete project built, expert engineering design, or ongoing support for a plant already running — Spans Envirotech has the right engagement model for your situation.
How to Choose
Every project starts with the right engagement model
Different projects need different types of support. Some clients want a single responsible party to deliver a complete plant. Others need rigorous engineering without giving up control of construction. And many need expert support to keep an existing facility performing. Scroll down to find the model that fits your project.
