Inspections and tests will be performed as outlined in this Plan to document the construction is proper and meets Project requirements. Periodically, the process will be refined based on worker-identified quality problems, test data, inspection results, audits, and MnDOT's satisfaction with the Project. SCOPE
This plan applies to all Work performed on the Project. RELATED DOCUMENTS
Contract Documents Special Provisions Materials Control Schedule
RESPONSIBILITIES
The Contractor is responsible for performing the work in accordance with all aspects of the Contract. At a minimum, the Contractor shall perform testing and inspection in accordance with this Construction Quality Plan. None of the th e Contractor’s quality staff have the ability to deviate from Project requirements or to interpret Project specifications. Their role is solely to ensure the finished Work meets the requirements of the Contract. Quality staff has the authority to stop any and all Work that does not meet the Contract requirements. FIELD PLAN SHEETS
The CQM is responsible for ensuring the contractors quality staff performing required observations, checks and documentation of plan sheets that are being used in the field for construction. When new RFC plans are released, the the Contractor’s quality staff will will review the plan sets with the foreman to make sure that the most up-to-date plan sets are being used. SUBCONTRACTORS AND SUPPLIERS
Contractor Quality Management Plans for each major subcontractor and supplier will be included in the Project files as an extension of this CQMP. The DQAM or CQM will review the QMPs for implementation on the project work. Contractor Management, subcontractors and supplier contracts will describe work or products needed and the schedule required. The documents will contain the quality requirements needed by the work or products. The responsibility for inspection and testing of off-site materials shall follow all applicable Mn/DOT specifications associated with that item. Subcontractors and suppliers will designate representatives to interface with the QM and Mn/DOT. Quality records will be provided to the QM for all work and products to demonstrate conformance to Project requirements. The subcontractors and suppliers will make provision for the QM and/or CAPM and Mn/DOT personnel to observe, sample, inspect, or test work and product at any point in their processes. The DQAM or CQM will conduct periodic audits of selected suppliers to verify initial and continued implementation of the QMP. PRODUCTS AND MATERIALS
Quality tests and inspections will be performed during the production of the materials, as materials arrive on the Project Site, and as they are incorporated into the construction. Tests and inspections will be performed by a combination of contractor staff, testers and inspectors, and subcontractor and supplier quality personnel. Suppliers will perform tests on materials as they are produced. Prior to the material arriving on the Project Site, testing information will be forwarded to the CQM demonstrating the material meets requirements. The CQM will also audit selected suppliers to assure they are following a quality management system and to review the Project requirements with the supplier. The supplier’s quality management system will be reviewed, along with test records from previous production and reporting of quality data during production will be established. Products and materials are identified from receipt and storage through installation. Where appropriate, a unique number will be assigned and a tag attached. Where traceability is required, the location of the product or material will be recorded. Handling
Products and materials are handled on site in accordance with supplier's recommendations, MnDOT's specific requirements, and good construction practice. When materials arrive at the Project Site, receiving personnel will document receipt of the material in accordance with the appropriate procedure. Quality Control will check material for conformance to Project requirements. Any damage or deficiency will be noted. The materials will be used or stored as appropriate for the material.
Some materials, such as concrete, will require physical tests as received and will be sampled to determine their conformance. The Work will be conducted following the proper test procedure and documented on the proper form according to this Construction Quality Plan. Packing slips, mill certificates, or other documents from the supplier showing conformance to requirements will be reviewed by QC and QA personnel and retained by QA. Three-ring binders will be used to compile certificates and will include an updated log of accepted shipments. Storage
Products or materials not immediately used will be stored. Material for indoor storage is placed in bins, shelving, racks, or pallets and positioned in neat and orderly condition for ease of retrieval. Material stored outdoors is placed on adequate dunnage and protected as required by the supplier. Protection
Some products and materials will require special measures to protect them from degradation. The supplier's requirements will be followed in providing the proper environment for the products and materials. The Project Manager will be responsible for providing proper conditions. QUALITY TESTING AND INSPECTION
During construction, various elements will be checked and compared to the requirements set forth in the RFP, MnDOT Standard Specifications for Construction (See Book 3), Special Provisions, and MnDOT Materials Control Schedule (Volume III). These checks will be performed following the appropriate procedure and documented on the proper form. Testing will be preformed to the Project minimums stated in the Materials Control Schedule. Additional tests will be performed as needed. Estimated annual quantities of materials will be used to determine the approximate number of tests and inspections needed annually. All documentation shall reference an Activity ID in the Contractors Schedule. Any inspection performed by MnDOT does not relieve the Contractor of its quality management responsibilities. CONTROL OF MONITORING AND MEASURING DEVICES
Monitoring and measuring equipment used on the Project will be appropriate for the work being performed, in working order, and calibrated periodically. When not in use, the devices will be protected from damage and stored in accordance with
manufacturer’s as well as Owner’s requirements . Records of the calibration will be maintained. Laboratories Any type of test that requires additional testing to assure that materials are meeting the Contract requirements will be tested on different equipment by different personnel. Independent Assurance Sampling and Testing (IAST) The quality teams will have all testers perform the required IAST tests. These tests will be done on an annual basis for any quality personnel that have performed a material test for the Project in that year. The CQM will keep records verifying completion of the required IAST tests. QUALITY RECORDS
Test forms, inspection forms, and material receipt forms will be provided to MnDOT through document control. Data from these tests will be manually entered into the Project's electronic document management system. MnDOT ’s TRACS will be used for the material testing database and Daily Field Reports. Reports from TRACS will be used to assure that testing rates for the materials installed are sufficient. Reports for the material certification of the Project will be produced from TRACS when possible and will be supplemented with the Word and Excel certification forms when needed. QUALITY AUDITS

CQP 201: Field Design Change Rev
, Date
PURPOSE
To establish the scope, responsibilities, procedures, and forms affecting and documenting changes proposed by the Contractor to address situations discovered after the design package has been Released for Construction. SCOPE
Design changes initiated by the Contractor to documents Released for Construction are completed under a Field Design Change (FDC). Examples of of Contractor-initiated Contractor-i nitiated situations that require modifications to the original RFC documents include: unanticipated site conditions, alternative construction method/material proposals from the Contractor, among many others. RESPONSIBILITIES
The Contractor generates Field Design Change requests. FDCs should be filtered through the Construction Manager (or (or his designee), and forwarded to Document Control for distribution to the Designer . The Post-Design Manager is responsible for responding to all FDC requests. The will facilitate the review of all FDCs according to the Post-Design Manager will requirements of the QMP. The Construction Manager is is responsible for controlling the construction activities once the FDC has been documented to avoid further work activities that may require removal or rework as a result of the FDC disposition. The Construction Manager will will keep the Project Manager , the Post-Design Manager , and the Department apprised of the impacts to ongoing construction operations as a result of the anticipated design change. The Construction Quality Manager will will be responsible for notifying field quality personnel in charge of assessing the work for conformance with the Quality Plan of the upcoming changes to the RFC documents. Field quality personnel will monitor the work elements impacted by the FDC, and report on observed activities, which may be contrary to the intended modifications. will sign each FDC prior to MnDOT’s MnDOT’s Project Manager or Construction Manager will Release for Construction. MnDOT reserves the right to take ten (10) days of review time for each FDC. PROCEDURE
The procedures outlined below are to be used to process all Field Design Changes. Revisions may require modifications to the RFC plans and/or specifications, and can be classified according to the following: Level 1 – 1 – Request Request for Existing Conditions Adjustments (Considered Minor in scope). These revisions are adjustments to match project elements with conditions encountered in the field. They are limited to minor dimensional and layout adjustments to released design documents, and do not impact future construction and installation. Level 2 – 2 – Request Request for Adjustments to Match As-Constructed Details (Considered Minor in scope, but require review for major implications). These accommodate specific details of work elements already constructed by the Contractor. They are limited to dimensional and layout adjustments to design documents released for construction, and do not impact future construction and installation. Level 3 – 3 – Request Request for Revision to Design Documents Released for Construction (Considered Major in scope). These are revisions to RFC documents that involve design changes that do not deviate from project requirements, but are considered to be major in scope. Examples include revisions to major dimensions and layout, materials changes, or design revisions to accommodate adjustments to the work. Revisions of this nature may impact several disciplines, and will undergo a review process prior to rerelease. Level 4 – 4 – Request Request for Deviation from Project Requirements (Considered major in scope). These are revisions to RFC documents that involve changes that deviate from Contract requirements. The proposed revisions should involve an isolated part of the project, and should be fully justified by the Contractor prior to MnDOT consideration. Revisions of this nature may impact several disciplines, and will undergo a review process prior to re-release.
Specific procedures follow: 1. FDCs are initiated by the Construction Manager (or his designee). The first point of contact for the initiator is Document Control, who will identify and reserve the next number in the FDC log. 2. Document Control will issue an FDC Notice providing the base information of the revisions requested. The FDC will be transmitted to the Design Manager or the Post-Design Manager (or his designee) for action. 3. The scope of the FDC will be thoroughly analyzed by the Design Manager or the Post-Design Manager to confirm the circumstances described in the FDC Notice. The Design Manager or the Post-Design Manager will enlist additional information from field personnel as necessary to clearly define the scope and detail of the revisions required, as well as to identify the schedule for FDC resolution. 4. If plan revisions are necessary, all design changes to plans, specifications, calculations, and reports will be sealed by a Minnesota licensed Engineer. All
design work will conform to the QC checking procedures governing design as identified in other sections of the QMP. 5. Plan and specification revisions classified as Major (includes Level 3 and 4 revisions and occasionally Level 2 revisions) will be subject to a design review and approval process similar to that for the original design. The Design Manager or the Post-Design Manager will classify FDC requests as minor or major, and will determine the scope of plan review necessary. 6. The FDC form will be completed by the Design Manager or the Post-Design Manager or his designee. This summary form will will identify the reason for the change, the revisions made, the specifications and plan sheets modified. 7. The completed FDC form and any plan revisions will be returned to Document Control for duplication and documentation, and will be forwarded to the Construction Manager accompanied by a Re-Release of Drawing transmittal. DISPOSITION
1. All check prints and design calculations calculati ons are stored in Document Control after the plans have been approved by the Design Manager or the Post-Design Manager. FIGURES AND FORMS

MnDOT’s structural metals inspection staff will provide quality assurance inspection at the fabricator’s plant on this Project. The MnDOT Onsite QA Inspector is responsible for notifying the MnDOT Structural Metals and Bridge Inspection Engineer when NCR’s have been generated. The MnDOT Structural Metals and Bridge Inspection Engineer is responsible for coordinating and processing all NCR’s with other MnDOT personnel. PROCEDURE The procedures outlined below are to be used to process all structural metals nonconformances. Nonconformances are classified as follows: Level 1 – NCR’s with applicable pre-approved repairs. This level is used to authorize repairs not in compliance with the specifications, applicable codes, and/or approved shop drawings but do not affect the integrity of the design. This process is conditional on the required repair procedures being included in the Fabricator’s approved QCP. If the procedures are absent from the approved QCP, this type of NCR will follow the Level 2 process.
When a nonconformance is identified, the NCR is generated by the Fabricator . The NCR is approved by the MnDOT Onsite QA Inspector . The Fabricator will supply a copy of the completed NCR to the MnDOT QA Inspector and the QM for their records. Level 2 – NCR’s without pre-approved repairs. This level is used to identify items that are fabricated incorrectly but do not affect the integrity of the design.
When a nonconformance is identified, the NCR is generated by the Fabricator . The Fabricator will send the NCR to the MnDOT Onsite QA Inspector and the QM. The MnDOT Onsite QA Inspector will fill out a Request for Deviation and submit the NCR to the MnDOT Structural Metals and Bridge Inspection Engineer who will perform a technical review and recommend the NCR for Acceptance. The QM shall notify the MnDOT Structural Metals and Bridge Inspection Engineer if they have concerns with the NCR or proposed recommendation. The MnDOT Structural Metals and Bridge Inspection Engineer will forward the NCR to the MnDOT Bridge Construction and Maintenance Engineer for Acceptance. After the NCR is Accepted, the MnDOT Structural Metals and Bridge Inspection Engineer will send the NCR to the QM and the MnDOT Onsite QA Inspector, who will forward the NCR to the Fabricator . The Fabricator will provide the MnDOT Onsite QA Inspector and the QM with a copy of the completed NCR for their records. Level 3 – NCR’s that affect the integrity of the design. This level is used to identify items that are not in compliance with the design.
When a nonconformance is identified, the NCR is generated by the Fabricator . The NCR is reviewed by the MnDOT Onsite QA Inspector who fills out a Request for Deviation. The NCR and Request for Deviation are forwarded to the MnDOT Structural Metals and Bridge Inspection Engineer who forwards the NCR and Request for Deviation to the QM for review and approval of the design change. A copy of the NCR and Request for Deviation is sent to the MnDOT Oversight Quality Management Specialist .
