520 Steel Bridges  \n520.1 Shop Drawings  \nThe fabricator's detailed shop drawings and steel erection drawings become a part of the project plans and are used in conjunction with the general plans. During steel erection, the engineer should make sure all members are placed in the proper position in the structure by checking match marks or identification marks on the members with the location shown on the erection drawing.  \nThe department does not approve shop drawings. The department may perform a quality assurance review on selected submittals. BOS and project leaders/managers may provide comments on the shop drawings before acceptance by the department. The department's review does not relieve the contractor or fabricator of the responsibility for quality control of the work, for obtaining acceptable results, for the accuracy of dimension and details, or for conformity of these drawings with the contract.  \nShop drawings for primary steel members and fabricated bridge components must be submitted to the department through the fabrication library. The fabrication library allows both BOS and project  \nleader/managers to select review status and send notifications to the fabricator. Project leaders/managers must accept the shop drawings through the fabrication library by changing this status.  \nProject leaders/managers should review the fabrication library submission standards, which include electronic shop drawing review guides. This document can be downloaded from:  \n[https://wisconsindot.gov/Pages/doing-bus/eng-consultants/cnslt-rsrces/strct/fab-sharepoint.aspx](https://wisconsindot.gov/Pages/doing-bus/eng-consultants/cnslt-rsrces/strct/fab-sharepoint.aspx)  \n520.2 Shop Inspection  \n520.2.1 General  \nBased on the location of the shop and inspector availability, quality assurance (QA) inspection of the structural steel in the shop may be performed by a BOS representative. Shop inspection reports are submitted to the WisDOT fabrication library by quality assurance inspectors during fabrication, and are available for review at:  \n[https://wisconsindot.gov/Pages/doing-bus/eng-consultants/cnslt-rsrces/strct/fab-sharepoint.aspx](https://wisconsindot.gov/Pages/doing-bus/eng-consultants/cnslt-rsrces/strct/fab-sharepoint.aspx)  \nIn the event that shop inspection reports are not available, the engineer should contact the SFU to ensure that the structural steel has been shop inspected.  \n520.2.2 Primary Members  \nPrimary members are critical members designed to carry load within the structure. Steel bridge primary members are listed in standard spec 506.3.1.1.  \nWhen structural steel members are delivered to a job site, if the region has concerns with the quality of the fabricated members provided, the region may arrange through BOS to have an on-site inspection made by an experienced shop inspector. This is not intended to be a complete inspection as to dimensions, etc. , but rather to look for the type of defects that result from faulty fabrication and welding procedures.  \nThe fabricator must submit certified mill test reports (CMTR) to the fabrication library. The project leader/manager must review these records before the start of fabrication. To avoid the incorporation of incorrect material into the structure, review of CMTRs for conformance to contract plans and  \nspecifications should be completed before assembly.  \n520.2.3 Fabricated Bridge Components  \nFabricated bridge components are inspected in the field. The engineer or designer will make and  \ndocument field inspections.  \nThe fabricator must submit certified mill test reports (CMTR) to the fabrication library. The project leader/manager must review these records before the start of fabrication. To avoid the incorporation of incorrect material into the structure, review of CMTRs for conformance to contract plans and  \nspecifications should be completed before assembly.  \n520.3 Field Handling and Storage of Structural Steel  \nStandard spec 506.3.24 and standard sp","cbCaig1Eba7Uvzk5","https://ap.wps.com/l/cbCaig1Eba7Uvzk5","pdf",1649013,11,"English","# 520.1 Shop Drawings\n## 520.2 Shop Inspection\n### 520.2.1 General\n### 520.2.2 Primary Members\n### 520.2.3 Fabricated Bridge Components\n## 520.3 Field Handling and Storage of Structural Steel\n## 520.4 Bearings\n### 520.4.1 General\n### 520.4.2 Bearing Pads","[{\"question\":\"What is the purpose of match marks or identification marks on steel members during erection?\",\"answer\":\"They help ensure each member is placed in the proper position in the structure by aligning the member marks with the locations shown on the erection drawing.\"},{\"question\":\"Does the department’s review of shop drawings remove the contractor or fabricator’s quality responsibilities?\",\"answer\":\"No. The review does not relieve the contractor or fabricator of responsibility for quality control, acceptable results, dimensional accuracy, and conformity to the contract.\"},{\"question\":\"What documents must the fabricator submit before fabrication, and when should the project leader/manager review them?\",\"answer\":\"The fabricator must submit certified mill test reports (CMTR) to the fabrication library, and the project leader/manager must review these records before the start of fabrication to ensure conformance with contract plans and specifications.\"}]","SECTION 520 Steel Bridges - Shop Drawings - Review and Inspections | PDF",1792795343,28]
