1 INTRODUCTION
The iTPCProjectManagement Plan (PMP) describes the coordination of effort bythe project team, including the processes and procedures used by the ProjectManager(PM), toensurethat theproject iscompletedontimeandwithinbudget.The PMP defines the project scope and the organizational framework, identifiesroles and responsibilities of contributors, and presents the work breakdownstructure(WBS),costandschedule.
1.1 ProjectBackground
BrookhavenNationalLaboratory(BNL), locatedinUpton,NY, isownedbytheU.S.DepartmentofEnergy(DOE)andoperatedbyBrookhavenScienceAssociates(BSA)under the U.S. Department of Energy Contract No. DE-SC0012704.

2.1 ScopeBaselineandkeyphysics
TheSTARDdetectorwasdesignedtomakemeasurementsofhadronproductionovera large solid angle, and it features detector systems for high precision tracking,momentumanalysis andparticle identification. It is the only experiment atRHICthatmeasuresparticlesover the fullazimuthalangleandovermomenta from100MeV/c to20GeV/c. Therefore, it iswell suited forboth characterizingheavy-ioncollisionsevent-by-eventandalsoinvestigatinglargetransversemomentumeffects.TheupgradetotheinnersectorsoftheSTARTPCwillincreasethesegmentationonthe inner pad plane and will renew the inner sector wire chambers. These twoimprovements will extend the capabilities of the TPC in many ways. Most

significantly, the enhanced tracking at small angles relative to the beamline willexpand the TPC’s acceptance out to pseudo-rapidity |η| ≤ 1.5, compared to thecurrentlimitationof|η|≤1.Furthermore,thedetectorwillhavebetteracceptancefortrackswithlowmomentum,aswellasbetterresolutioninbothmomentumanddE/dx for tracks of allmomenta. These changeswill enable the collection of datathatiscriticaltothephysicsmissionforPhase-IIoftheBeamEnergyScan(BES-II).The improved dE/dx and momentum resolution, as well as tracking at higherpseudorapidity, will provide the foundation for another proposed upgrade - theendcaptimeofflightproject(endcap-TOF)bytheSTAR/CBMcollaboration.ThePhysicsprogram,andthetechnicaldescriptionoftheprojectispresentedintheiTPCTechnicalDesignReport(TDR),availableasSTARNoteSN06441.There are two key physics topics that the upgrade will enable (i) net-proton kurtosis measurements in a search for a critical point in the QCD phase diagram, and (ii) measurements of low mass di-electron pairs to explore the modification of vector mesons in connection with the approach to chiral symmetry restoration in a dense medium. The enhanced capabilities provided by the iTPC upgrade will allow a full study of observables which are sensitive to changes in correlation length near the critical point. For example, in the vicinity of a critical point, the net-proton kurtosis is expected to rise as the fourth power of the size of the rapidity window but then saturate as the window becomes comparable to, or larger than, the correlation length in the system. The iTPC improvements with increased rapidity coverage will allow the fullest possible coverage of the collision region to establish the existence of a rapid rise in the kurtosis signal and, if found, to more fully map out its properties. For the low mass di-electron measurements, the iTPC upgrade improves the acceptance of the detector but also reduces the hadron contamination which is responsible for and is the dominant source of systematic uncertainties in previous measurements. The reduction in uncertainty made possible by the iTPC project will allow the full exploitation of the increased statistics to be collected during BES-II. Full characterization of any meson broadening, and distinguishing between competing theoretical interpretations for a quantitative assessment of how the system approaches chiral symmetry restoration, will only be possible with these improvements.
2.2 TechnicalPerformanceParameters
ThetechnicalperformanceparametersanddeliverablesaregiveninTable2-1.Thetwomiddle and left columns are the Key Performance Parameters (KPP) and theUltimate Performance Parameters (UPP). Fulfilling these parameters will ensurethat the iTC can reach its physics goal inBES-II. Theparameters are chosen suchthat they can be determined before beamoperations. It is known from the initialconstruction and performance of the STAR TPC that if these goals are met then1https://drupal.star.bnl.gov/STAR/starnotes/public/sn0644

2.7 ForeignContributionsShandong University (SDU) is a strong STAR institution with clear commitment to the iTPC project. A ‘973’ State Key Project from the Chinese Ministry of Science and Technology for RHIC-STAR physics was approved in 2013. It provided 2M RMB (~ $308K, currently), to support the iTPC R&D in Shandong University and SINAP in China. The University also provided support (~ 0.5M RMB) for the start-up of the laboratory facilities. For the full production and assembly of the inner sector MWPCs (24 + spares) in China, SDU submitted a proposal for additional support in March of 2015 together with USTC and SINAP, and was awarded ~3M RMB as an NSFC key project for international cooperation (2016~2020). The award was received in September 2015. There are additional in-kind contributions from Shandong University valued at 1.5M RMB. These funds are not included in the project costs. The production at SDU will take place at a refurbished facility, and the engineer, technicians and physicist labor are contributed to the project. The work at SDU is included at high level in project file, as is milestones for production steps.

AppendixC-RiskManagementPlan
IntroductionProject risk is a measure of the potential inability to achieve project objectiveswithin defined scope, cost, schedule, and technical constraints. Project riskmanagement entails the systematic process of identifying, quantifying, handling,tracking, and reporting risk events. Risk events are defined as individualoccurrencesorsituationsthataredeterminedtohavepotentialnegativeorpositiveimpactstoaproject.Projectriskmanagementincludesmaximizingtheprobabilityand consequences of positive events and minimizing the probability andconsequencesofadverseeffectstoaproject.The iTPC project team is committed to managing project risk effectively byemploying a comprehensive strategy that emphasizes risk identification andprevention or mitigation. The overall objectives of the Risk Management Plan(RMP) are to prevent or minimize unnecessary project costs and/or scheduledelays, while achieving the project scope. This Risk Management Plan (RMP)describestheoverallphilosophyandprocessforriskmanagement.RiskAssessmentfortheiTPCProjectTheRiskManagementPlan takesabroadviewof the iTPC project to identifyandaddress specific risks that requireassessment,mitigationand tracking. While theinitialriskassessmentwillbefocusedontheestablishmentofavalidbaseline,riskassessment will also be an ongoing process throughout the project life cycle. Inaddition, the following assumptions will serve to guide and bound the riskassessment:
• TheprojectwillbeexecutedinaccordancewithRHIC/STARandBrookhavenNationalLaboratoryPoliciesandProcedures.
• The project scope will be limited to the scope of the Memorandum ofUnderstanding(MOU)betweenSTARandtheBNLAssociateDirectorsOffice.
• Theinstallation,integration,commissioningandoperationoftheprojectwillbe executed in accordance with RHIC/CAD and STAR Policies andProcedures.
• The project will be carried out by the STAR Collaboration and will bedependentontheSTAR/RHICoperationsschedule.
