Members of the New Lock at the Soo Integrated Project Office (IPO) team along with engineers from the Inland Navigation Design Center (INDC) acknowledged a significant milestone within this Detroit District’s high visibility mega project; they’ve completed the review and approval of over 2,600 technical submittals. The average, run-of-the-mill construction project typically sees a couple hundred submittals. 
Maintaining momentum requires the contractor to provide technical assurances that the execution strategies they intend to employ will meet or exceed contractual requirements and specifications. These assurances, provided in the form of a written submittal (transmittal) offer detailed written and pictorial descriptions and renderings of how the contractor intends to perform various tasks. Articulating these strategies and gaining Corps of Engineers concurrence permits the contractor to proceed without incurring delays, achieve milestones, and invoice the government in a timely manner.
This New Lock at the Soo celebrated milestone pales in comparison to the fact that the IPO, INDC, and their contractor may publish and review yet another 3,000 submittals before the first freighter makes its way through the new lock.
