Commissioning & Startup

We work with design teams to develop and use advanced process models to predict and quickly implement the necessary operational parameters to achieve the desired effects. While many projects are plagued by problems and delays during startup, we have found that our approach facilitates rapid, successful startup and turnover.

  • MWH is unique in that we employ a commissioning and startup manager from the very beginning of the project.
  • We use process modeling to make better sequencing decisions for construction activities and commissioning.
  • The commissioning and startup process begins well before it is time to turn on the switch.



  • MWH created and owns an electronic database solution called ActiveManuals which focuses on three principal types of manuals:
    • Operations
    • Maintenance
    • Business
  • Our ActiveManuals implementation team knows the challenges of onsite project manual organization and have designed the database for intuitive and interactive solutions.

Everyone in the City, including myself and upper management, are very pleased with the success of this project. We’re meeting the permit requirements and we’ve had minimal impact on City airport operations; we have a glowing safety record, no lost time accidents; and we’ve been able to maintain continuous operations of our existing treatment plant. We have met every challenge with success and, yes, I can say unhesitatingly that we are extremely pleased with this project.
