The fourth and final phase of this long term project, is the most complex of the four. Multiple tie in points to existing services, new structures and retro fits of existing tanks, as well as shutdowns during non-peak demand time frames, are the major challenges for a project of this size. With a skilled labour force, and the proximity to our fabrication shop, we have been easily able to maintain and push to accelerate the schedule. All of the aeration piping has been fabricated in our shop, and transported to the jobsite. This allow us to keep a high quality for production and the speed necessary for delivery onsite.
