===720.1.2 Procedure===
[https://www.modot.org/missouri-standard-specifications-highway-construction Sec 720] requires the contractor to submit electronically one set of the manufacturer’s (shop drawings) design plans, details and computations for each individual wall structure to the engineer. Shop drawings should be reviewed by appropriate MoDOT Division/District per [[106.16_Special_Designs_and_Shop_Drawings#106.16.2_Shop_Drawings|EPG 106.16.2]].

The Bridge Division maintains a list of pre-approved MSE wall systems (see [https://www.modot.org/bridge-pre-qualified-products-list Bridge: Pre-qualified Products List – MSE wall]). If a MSE wall system is not on the pre-qualified products list, it will need to clear the pre-approval process by Bridge Division before construction can begin. The pre-approval process can take several months and could possibly lead to rejection of the MSE wall system. The contractor assumes all risk in time and cost if they submit an MSE wall system that has not received pre-approval.

====720.1.2.1 Contract Sampling and Testing Requirements====
Once District Materials has received a copy of the MSE wall plans, they should edit the Contract Sampling and Testing Requirements accordingly. Since MSE wall designs vary greatly, care should be given as to what components and quantities are required. At a minimum, there should exist a requirement for reporting the entire approved wall system. Also, since the granular backfill plays a crucial role in supporting the structure, there should be a requirement for the acceptance of this material.

====720.1.2.2 Certifications====
Certifications should be received and checked for conformance to the various portions of Secs [https://www.modot.org/missouri-standard-specifications-highway-construction 720], [https://www.modot.org/missouri-standard-specifications-highway-construction 1052], [https://www.modot.org/missouri-standard-specifications-highway-construction 1011] and others necessary. The project office shall keep these certifications as part of the project files.

==1052.3 Special Designs and Shop Drawings==
All wall systems should be from the [https://www.modot.org/bridge-pre-qualified-products-list Bridge: Pre-qualified Products List – MSE wall]. For structural walls, individual projects will have a unique shop drawing showing how to build the wall from the approved system. Deviations from the approved shop drawings should not be allowed.
