Engineering, procurement and project management, run as one connected process so the requirement that is specified is the material that arrives.

**In short:** JJ Projects provides three connected services: industrial engineering (mechanical, process and refractory), equipment and material procurement (sourcing, evaluation, purchase-order follow-up, inspection coordination and delivery), and project management (planning, estimating, procurement and field management). The company is based in Houston, Texas, and works across the Americas.

Each service can be engaged alone. Most projects use them together, because a requirement that is engineered, bought and coordinated by one team has fewer hand-offs where details are lost.
