USACE ECB 2023-9 Civil Works Design Milestone Checklists -- Category: Guidance  

The purpose of this Engineering and Construction Bulletin (ECB) is to provide Project Delivery Teams (PDTs) with a list of submittal requirements by design milestone to identify design issues early enough to allow for mitigation or resolution. This ECB serves as a roadmap and a best practice and is not a comprehensive list of requirements. The items in this checklist have been associated with quality issues that impact project schedule and increase project costs. This ECB is intended to be complementary to ER 1165-2-217 and provide a clear set of expectations for both designers and reviewers. The forthcoming update to Engineering Regulation (ER) 1110-2-1150 will provide additional details and milestone requirements.
