CQP 201: Field Design ChangeRev , Date

PURPOSE

To establish the scope, responsibilities, procedures, and forms affecting anddocumenting changes proposed by the Contractor to address situations discoveredafter the design package has been Released for Construction.

SCOPE

Design changes initiated by the Contractor to documents Released for Construction arecompleted under a Field Design Change (FDC). Examples of Contractor-initiatedsituations that require modifications to the original RFC documents include:unanticipated site conditions, alternative construction method/material proposals fromthe Contractor, among many others.

RESPONSIBILITIES

The Contractor generates Field Design Change requests. FDCs should be filteredthrough the Construction Manager(or his designee), and forwarded to DocumentControl for distribution to the Designer.

The Post-Design Manageris responsible for responding to all FDC requests. ThePost-Design Managerwill facilitate the review of all FDCs according to the

requirements of the QMP.

The Construction Manageris responsible for controlling the construction activitiesonce the FDC has been documented to avoid further work activities that may requireremoval or rework as a result of the FDC disposition. The Construction Manager willkeep the Project Manager, the Post-Design Manager, and the Department apprisedof the impacts to ongoing construction operations as a result of the anticipated designchange.

The Construction Quality Managerwill be responsible for notifying field qualitypersonnel in charge of assessing the work for conformance with the Quality Plan of theupcoming changes to the RFC documents. Field quality personnel will monitor the work

elements impacted by the FDC, and report on observed activities, which may becontrary to the intended modifications.

MnDOTs Project Manager or Construction Managerwill sign each FDC prior toRelease for Construction. MnDOT reserves the right to take ten (10) days of reviewtime for each FDC.


12/85




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 beclassified according to the following:

Level 1Request for Existing Conditions Adjustments (Considered Minor inscope). These revisions are adjustments to match project elements with conditionsencountered in the field. They are limited to minor dimensional and layout adjustmentsto released design documents, and do not impact future construction and installation.

Level 2Request for Adjustments to Match As-Constructed Details (ConsideredMinor in scope, but require review for major implications). These accommodatespecific details of work elements already constructed by the Contractor. They are

limited to dimensional and layout adjustments to design documents released forconstruction, and do not impact future construction and installation.

Level 3Request for Revision to Design Documents Released for Construction(Considered Major in scope). These are revisions to RFC documents that involvedesign changes that do not deviate from project requirements, but are considered to bemajor in scope. Examples include revisions to major dimensions and layout, materialschanges, or design revisions to accommodate adjustments to the work. Revisions ofthis nature may impact several disciplines, and will undergo a review process prior to re-release.

Level 4Request for Deviation from Project Requirements (Considered major in

scope). These are revisions to RFC documents that involve changes that deviate fromContract requirements. The proposed revisions should involve an isolated part of theproject, and should be fully justified by the Contractor prior to MnDOT consideration.Revisions of this nature may impact several disciplines, and will undergo a reviewprocess prior to re-release.

Specific procedures follow:

1. FDCs are initiated by the Construction Manager (or his designee). The first point ofcontact for the initiator is Document Control, who will identify and reserve the nextnumber in the FDC log.

2. Document Control will issue an FDC Notice providing the base information of therevisions requested. The FDC will be transmitted to the Design Manager or thePost-Design Manager (or his designee) for action.

3. The scope of the FDC will be thoroughly analyzed by the Design Manager or thePost-Design Manager to confirm the circumstances described in the FDC Notice.


13/85




The Design Manager or the Post-Design Manager will enlist additional informationfrom field personnel as necessary to clearly define the scope and detail of therevisions 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. Alldesign work will conform to the QC checking procedures governing design asidentified in other sections of the QMP.

5. Plan and specification revisions classified as Major (includes Level 3 and 4 revisionsand occasionally Level 2 revisions) will be subject to a design review and approvalprocess similar to that for the original design. The Design Manager or thePost-Design Manager will classify FDC requests as minor or major, and willdetermine the scope of plan review necessary.

6. The FDC form will be completed by the Design Manager or the Post-DesignManager or his designee. This summary form 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 DocumentControl for duplication and documentation, and will be forwarded to the ConstructionManager accompanied by a Re-Release of Drawing transmittal.

DISPOSITION

1. All check prints and design calculations are stored in Document Control after the

plans have been approved by the Design Manager or the Post-Design Manager.
