2 Del. Admin. Code § 4.7
DelDOT has developed Standard Construction Details to provide consistency on State-maintained projects. Standard Construction Details are available on DelDOT's website (www.DelDOT.gov).
The Standard Construction Details shall be utilized in the construction unless there is an unusual circumstance requiring a special design. The plans shall show construction details only for those construction elements not shown in DelDOT's Standard Construction Details.
If there are engineering elements, including but not limited to, structural designs required on a plan that are not included in the Standard Construction Details, then detailed engineering designs and calculations signed and sealed by a Delaware-registered professional engineer shall be submitted to DelDOT for review and approval. All structural elements shall be designed in accordance with AASHTO LRFD (Load and Resistance Factor Design) Bridge Design Specifications (latest revised edition).
The project shall be constructed using the latest version of DelDOT's Standard Construction Details that are in effect at the time of construction.
Specifications for frequently used construction items have been prepared by DelDOT. Copies of these Standard Specifications are available online at (www.DelDOT.gov).
Construction shall be in accordance with the latest version of DelDOT's Standard Specifications, Supplemental Specifications, and any Special Provisions that are in effect at the time of construction. Should it be necessary to construct an item for which a standard does not exist or where it is desired to modify the Standard Specifications, Supplemental Specifications, or Special Provisions, additional details and/or notes along with any applicable references to Nationally Accepted Standards (NAS) shall be included on the plans to adequately document any modified designs.
