Structural Fabrication Quality Manual
The Bureau of Bridges and Structures Construction Section has developed a Structural Fabrication Quality Manual. The manual is referenced in the MDOT Materials Quality Assurance Procedures Manual and is located on the Structural Fabrication Unit’s (SFU) website. A brief description of the manual is presented below.
Chapter 1 (General Information): Existing MDOT Structural Fabrication Quality Assurance Guidance Document is rolled into this manual with the addition of a narrative report writing section.
Chapter 2 (Fabrication Inspection Procedures): Existing fabrication inspection procedures from MQAP Manual with the following general revisions:
- Formatting update;
- Revised original MQAP numbering system;
- Updates to reflect current naming convention;
- Revised reference documents;
- Added referenced to ITPs;
- Revised procedures to accurately reflect actual processes; and
- Revised reporting section.
Chapter 3 (Inspection and Test Plans): New Inspection and Test Plans (ITP) supplement the fabrication inspection procedures shown in Chapter 2 by providing more detailed step by step inspection and test requirements, activity type, and potential option for reduced inspection (Level II) for less critical products. The following standard ITPs were developed:
- Non-Prestressed Concrete: Level I
- Non-Prestressed Concrete: Level II
- Prestressed Concrete: Level I
- Prestressed Concrete: Level II
- Structural Steel: Level I
- Structural Steel: Level II
Chapter 4 (Supplier Qualification Program): The Structural Fabrication Unit’s Supplier Qualification Program can be found in this chapter and currently consists of one Supplier Qualification Standard (SQS) for prestressed concrete beams. This SQS becomes effective for the October 2020 Letting. The chapter allows plenty of room for growth to include other products in the future.
Chapter 5 (Approved Supplier List): The Structural Fabrication Unit’s Approved Supplier List (ASL) can be found in this chapter and currently consists of one ASL for prestressed concrete beam. This ASL becomes effective for the October 2020 Letting. The chapter allows plenty of room for growth to include other products in the future.
