3Cayuga Project TeamOwners: MnDOT Metro District – Project Manager Joey LundquistCooperating Agencies: City of St. Paul & Ramsey CountyConsultant Team:Prime – HDR Engineering, Inc.Subconsultants – AET, Bonestroo/Stantec, HZ United, Jacobs, LHB, Cambridge Systematics
4Project DescriptionReconstruct I-35E from University Avenue to north of Maryland AvenueConstruct a full new interchange at Cayuga Street - replacing and closing the partial interchange at Pennsylvania AvenueReplace I-35E bridges over Pennsylvania Avenue, BNSF RR, Cayuga Street/BNSF RR, and Maryland Avenue over I-35EAdd new bridges on Cayuga Street over BNSF and Terrace Court, on SB I-35E ramps over BNSF, and on the new frontage road over BNSFConstruct a MnPASS Express Lane in each direction on I-35E through the project area
5Project BenefitsReplaces bridges and pavements that are reaching the end of their service lifeExtends the auxiliary lane on NB I-35E that starts in downtown St. Paul to Maryland Avenue, providing more room for drivers to safely mergeInitiates the first phase of the addition of a MnPASS Express Lane on I-35E from downtown St. Paul to the northern suburbsProvides better interchange spacing on I-35E between Maryland Avenue and University Avenue by shifting the partial interchange at Pennsylvania Avenue to a full interchange at Cayuga StreetProvides significantly improved regional access for St. Paul’s Phalen BoulevardExtends the Gateway Trail from Cayuga Street to University Avenue and adds sidewalks and trails to Pennsylvania Avenue and Cayuga Street
7MnDOT CPM Specifications 5.8.2 Project SchedulingThe Contractor will prepare and utilize a cost and resource loaded Critical Path Management (CPM) schedule to manage their deliverables.The Contractor must use Primavera P6 for this schedule.The baseline schedule will not extend beyond any contractual completion dates or contain negative float. The baseline schedule will include the entire scope of work and how the Contractor plans to complete all work contracted.Lags/Leads are subject to the consent of the Project Manager.The Contractor will remove any Lags/Leads and replace with an activity upon request of the Project Manager.Each activity will:(1) have a unique activity description and contain a verb,(2) be a duration of not more than thirty (30) working days, unless otherwise authorized by the Project Manager,(3) have at least one predecessor and one successor activity, except for Project start and finish respectively, and (4) express activity durations in days.
8Specifications (continued) Items provided by MnDOT:MnDOT will develop work breakdown structure (WBS) coding. The Contractor will incorporate the WBS coding to applicable schedule activities.Contractor Tasks:Contractor will cost load each schedule activity with applicable roles and resources, with respective estimate of hours loaded for each role or resource.Contractor will code each schedule activity with applicable activity code. The activity code will be called PPMS with values equal to the activity codes identified in each task.Contractor will update the schedule with activity percent completeContractor will update the schedule with actual resources applied to each activity.Contractor will submit an electronic schedule in Primavera P6 (.xer) format.
9Why a CPM Schedule? Get Organized Verify the work can/will be completed in required time frame.CommunicateA logical approach to executing the workUnderstanding of deliverable requirementsRelationship between disciplines; survey, roadway, structures, drainage, etcExpectationsAdjustments for changeVerify / Track ProgressPlanned versus Actual - DatesPlanned versus Actual - Resource UtilizationPlanned versus Actual – Cost Expenditure and Payment verification
17Schedule Updates – Earned Value EV is tool used to analyze cost status; budget vs. actual vs. earned cost
18Benefits of Design CPM on Cayuga OrganizationDefine deliverables in an organized formatEnsure all contracted deliverables are accounted forActivities are assigned to individualsApply cost to activitiesCommunicationRelationship between disciplines and other partiesResponsibility - activities are assigned to individuals, companies, DOTWhen deliverables are requiredAnalysisOn time – baseline comparison and float analysisOn budget – earned value analysisRisk or Impact mitigation – All parties can identify potential risks and mitigate effects, or prove/disprove claims

20Sample Linear Project: Time + Location Location (by mile post, stations, km, feet etc)RoadwayBridgeTunnelTimeIn contrast, let’s take a look at linear schedules. In addition to your Gantt chart’s TIME ONLY information, linear schedule displays information about the location as well. It can be by mile post, stations, km, feet etc.Let’s look at a sample project in a linear format that includes roadway, bridge and tunnel work.You can see that one gets a very concise look into a project – and it all could be on ONE PAGE.For example, let’s looks at the bridge work. One starts with the base work for the bridge. Each green, grey. Blue and red figure represents different work element, following bridge elements work and bridge deck.The most precious element of this display – empower YOUR client with the information. That’s what they hire us for.

At first your reaction may be – it’s very busy, filled with rectangles and slanted lines. But once you start looking at the legend and areas of work, it starts making more sense. Let’s start walking top-down, you have the information about ROW parcelsEmpower YOUR client with information at their fingertips. I have empowered mine and I know it works.
