Chg.): 09-18-24 APPENDIX A: PROJECT PROCESS – CRITICAL DECISION REQUIREMENTS In order to apply project management best practices to capital asset projects post Analysis of Alternatives (AoA) approval, a performance baseline must be established. This performance

baseline is defined as all cost, schedule, and scope required to complete all Critical Decision (CD) activities between each of the CD phase approvals (CD-X, where X is 1, 2, or 2/3, as applicable). Reporting progress for all phases of the project will be done following the applicable Office of InfrastructureAcquisition and Project Management (NA-90APM) standard practices. 1. Pre CD-0: Prepare Mission Need for Approval. a. Develop Mission Need. When a credible performance gap is identified between current capabilities and those required to achieve the mission, the Heads of NNSA Elements lead the development of a Mission Need Statement (MNS) that translates mission need into functional requirements. The MNS must not be written to assume any particular solution, whether material or non-material. It is important that the Heads of NNSA Elements engage NA-APM90 at this phase so a Headquarters Project Manager (HQPM) can be added to the project team. The HQPM provides assistance to ensure applicable standard practices, policies, and strategic guidance are followed to get the project off to a good start. Also see Department of Energy (DOE) Guide (G) 413.3-17, Mission Need Statement. b. Prepare the Program Requirements Document (PRD). The Heads of NNSA Elements must develop and maintain the PRD during the life of the project, as required by Business Operating Procedure (BOP) 413.2 Admin Chg. 1, Program Requirements Document for Construction Projects. Before CD-1, the PRD provides the framework from a program perspective for NA-APM90’s development of the acquisition strategy. c. Identify and Provide Funding. The responsible Heads of NNSA Elements establish the Rough Order of Magnitude cost range and provide funding for capital asset projects from appropriated funds. The Heads of NNSA Elements formulate the budget details in accordance with NAP 130.1A, Planning, Programming, Budgeting, and Evaluation (PPBE) Process. The Heads of NNSA Elements are responsible for ensuring adequate resources, including Other Direct Costs to support the FPD, are provided throughout the CD process. 2. Post CD-0/Pre CD-1: Prepare Alternative Selection and Cost Range for Approval. a. Establish and Manage the Integrated Project Team (IPT). Upon approval of the mission need for a capital asset project, the Heads of NNSA Elements establish an IPT comprising NNSA field office personnel, NNSA Element personnel, project and acquisition professionals, subject matter experts, and contractors (when appropriate but not required) and other federal organizations. Leadership of the IPT transitions to the NA-APM90 Federal Project Director (FPD) after completion of the AoA Alternative Selection Document (ASD). NA-APM90 Appendix A NNSA SD 413.3 APA-2 05-18-21 Chg. 1 (Admin. Chg.): 09-18-24 assigns project and acquisition professionals to the IPT to support the development of all project requirements. It is important to include representatives from the Office of Environment, Safety, and Health Safety, Infrastructure, and Operations (NA-50ESH) to advise on nuclear safety and infrastructure issues; the Office of Defense Nuclear Security (NA-70) to advise on safeguards and security; the Office of Infrastructure (NA-90) to advise on the infrastructure lifecycle; the Office of Information Management (NA-IM) to advise on IT Standards, Enterprise Architecture, and Cybersecurity; and Management and Budget (NA-

MB) to advise on AoA’s and cost estimation, as well as other subject matter experts who would contribute to the success of the project. Also see DOE G 413.3-18A, IPT Guide for Formation and Implementation. b. FPD Appointment. NA-APM90 identifies the appropriately certified FPDs who can be assigned to specific projects. The FPD is assigned after completion of the AoA ASD. c. Develop Alternatives and Finalize AoA. For projects seeking CD-1 approval, NA-MB conducts an AoA that is independent of the contractor organization that would benefit from the proposed project (e.g., Management and Operating Contractor, [M&O]). The AoA must be conducted in accordance with SD 413.3- 3BOP 413.6, Analysis of Alternatives. For additional information, see GAO-16- 22, AMPHIBIOUS COMBAT VEHICLE: Some Acquisition Activities Demonstrate Best Practices; Attainment of Amphibious Capability to be Determined. It is important that the Heads of NNSA Elements engage early with NA-MB to understand the requirements for the AoA, both in terms of process and products. NA-1.3 will conduct an independent review of the completed AoA. d. Develop the Acquisition Strategy. NA-APM90 develops the acquisition strategy, in consultation with the Heads of NNSA Elements, to identify the high-level plan for satisfying the mission need in the most effective, economical, and timely manner. The Acquisition Strategy must be approved by the Program Secretarial Officer (PSO) prior to the CD-1 Energy System Acquisition Advisory Board (ESAAB) (or Equivalent Energy Systems Acquisition Advisory Board Equivalent (ESAAB-E) meeting. After approval of the Acquisition Strategy and CD-1, the responsible Contracting Officer (CO) develops and documents the Acquisition Plan to specify the contract type in accordance with sound business practices, statutory, regulatory, and policy requirements, which is approved by the Senior Procurement Executive or designee. For additional information, see NA-APM90 Standard Practice 02, Acquisition Strategy; DOE G 413.3-13, Acquisition Strategy Guide for Capital Asset Projects; DOE Acquisition Guide, Chapter 7; and Federal Acquisition Regulation (FAR) parts 7 and 34. e. Develop the CD-1 Preliminary Project Execution Plan (PPEP). NA-APM90 leads the development of the CD-1 PPEP, which describes the organizational framework and overall management system for the project from AoA approval to CD-1 approval. The CD-1 PPEP should be submitted for approval within 30 days NNSA SD 413.3 Appendix A 05-18-21 APA-3 Chg. 1 (Admin. Chg.): 09-18-24 of the AoA approval. Concurrent with initiating the development of the CD-1 PPEP, NA-APM90 leads the development of the Design Management Plan (DMP). After the CD-1 PPEP is approved, NA-APM90 must develop the project’s safety basis and CD-1 performance baseline to manage the cost, schedule, and scope to CD-1 approval. NA-APM90, the program manager, and the Project Management Executive (PME) approve scope changes in accordance with the change control thresholds in the approved CD-1 PPEP. The CD-1 PPEP must include preliminary key performance parameters. For additional information see DOE G 413.3-15A, Project Execution Plans. f. Develop the DMP. NA-APM90 leads the development of the DMP, which establishes the anticipated levels of design maturity at each CD phase. The DMP must be developed as early as possible after approval of the AoA to ensure that

design activities are executed to the defined plan. The main purpose of the DMP is to define the approach for execution of design activities and to ensure that quality and consistency are maintained throughout the design process. The DMP includes the appropriate CD-1 and CD-2 performance baselines to manage the cost, schedule, and scope of the design effort. The DMP is tailored to both design-bid-build and design-build projects. For additional information see DOE G 413.3-1, Managing Design and Construction Using Systems Engineering. g. Develop the Conceptual Design. The NA-APM90 FPD leads the conceptual design team. As a part of this effort, the FPD prepares a CD-1 PPEP that defines roles and responsibilities, a DMP, and implements a CD-1 performance baseline with change control protocols. Development of the conceptual design is an iterative process to define, analyze, and refine project concepts using a systems engineering methodology. The conceptual design conforms to the design guidance in Appendix D, (Conceptual and Preliminary Design Guidance). Progress updates and design development status are provided to senior leaders through monthly briefings. h. Develop the CD-2 PPEP. The FPD is responsible for updating the CD-1 PPEP to describe the organizational framework and overall management system for the project from CD-1 approval to CD-2 approval. The CD-2 PPEP must be approved prior to CD-1 approval. Included in the update to the PPEP, NA- APM90 must identify the CD-2 performance baseline to manage the cost, schedule, and scope to CD-2 approval. NA-APM90, the program manager, and PME approve scope changes in accordance with the change control thresholds in the approved CD-2 PPEP. For additional information see DOE G 413.3-15A, Project Execution Plans. i. Exemptions, Equivalencies, and Waivers. A project may seek exemptions or equivalencies to the requirements in DOE directives in accordance with the process described in DOE O 251.1D, Departmental Directives Program, Appendix E. Examples include an equivalency for fire protection system requirements, an exemption from a natural phenomenon hazard requirement, a Appendix A NNSA SD 413.3 APA-4 05-18-21 Chg. 1 (Admin. Chg.): 09-18-24 waiver from meeting Leadership in Energy & Environmental Design (LEED) Gold certification as required by DOE 413.3, etc. Such exemptions, equivalencies, and waivers represent a risk to the project until approved. Projects requesting an exemption, equivalency, or waiver should place a high priority on having the request approved before the final conceptual design report. If they are not approved prior to the final conceptual design report, the associated risk item(s) should be carried in the risk register and the project estimate should include the unrealized risk value. The Associate Administrator for InfrastructureAcquisition and Project Management (NA-90APM-1) may allow requests that have not been approved beyond the final conceptual design report under special circumstances and such items should be discussed as major issues in the monthly project reviews until disposition is completed. 3. Post CD-1/Pre CD-2: Prepare Performance Baseline for Approval. a. Baseline Development. NA-APM90 formalizes the cost, schedule, and scope of a project at CD-2, and measures success against this baseline at project completion, including key performance parameters. The project requirements, identified in the approved PRD, and proposed funding profile are used to develop the project

cost and schedule baseline. The FPD is responsible for developing the total project performance baseline, which is validated by NA-APM90 or the DOE Office of Project Management (DOE-PM) based on the dollar threshold outlined in DOE O 413.3. The FPD obtains concurrence of the project baseline from the Heads of NNSA Elements, through concurrence on the Project Execution Plan (PEP), and obtains approval from the PME through the ESAAB process. The preliminary design must conform to the design guidance in Appendix D. Prior to baseline approval, nuclear project designs must conform to the design criteria specified in DOE O 413.3. During the period between CD-1 and CD-2, the FPD monitors the CD-2 performance baseline performance using project management principles and Earned Value Management (EVM) methodologies and techniques, in preparation for approval of CD-2, Approve Performance Baseline. b. Establish a Project Management Office (PMO), if applicable. A PMO provides a full-time team dedicated to the project to ensure project delivery is in accordance with the established cost, schedule, and scope baselines. For a Major System Acquisition (MSA) project, NA-APM90 determines if a PMO should be established. Establishment of a PMO must be approved by the Administrator (NA-1). c. Develop the PEP. The FPD is responsible for drafting and updating the PEP prior to CD-2 approval. The PEP is a living document that is based on the CD-2 PPEP and must be updated to capture changes to project systems, processes, procedures, and personnel. The FPD, program manager, NA-APM90, and PME approve scope changes in accordance with the change control thresholds in the approved PPEP or PEP. NNSA SD 413.3 Appendix A 05-18-21 APA-5 Chg. 1 (Admin. Chg.): 09-18-24 d. Plan for Site Integration. The FPD, Heads of NNSA Elements, through the IPT, establish a plan for site integration. Planning for site integration involves identifying site interface issues and infrastructure requirements in order to mitigate barriers to construction execution. Clear organizational interface and responsibilities need to be documented and agreed upon by all involved parties, as codified in the PPEP or PEP, Commissioning Plan, and Startup Plan, or as a standalone plan. e. Award and Administer Design Contracts or Interagency Agreements (IAs). Design contracts or IAs are awarded and managed according to the DMP. NA- APM90 or its agent awards design contracts, work authorizations, and IAs to support project requirements. To ensure successful outcomes, close coordination is expected between acquisition staff across the enterprise. Design progress and performance is measured against the CD-2 performance baseline. f. For conventional, non-nuclear construction, the design can be less than 90% complete prior to CD-2. Through an IPR, NA-APM90 ensures that adequate definition exists to provide a budget quality cost and schedule estimate for the total project performance baseline. Projects designated as Hazard Category 1, 2, or 3 nuclear facilities must achieve at least 90% design maturity before CD-2. 4. Pre CD-3A: Long Lead Procurements. A CD-3A package can be submitted in conjunction with another CD or separately. Some potential reasons to pursue a CD-3A authorization include the following: a. Purchasing long-lead materials or long-lead equipment. b. Fabrication requirements. c. Limited site preparations — Some examples include removal of existing equipment

or acquiring the lay-down area. 5. Pre CD-2/3: Approve Performance Baseline and Start of Construction Execution. The preparations for a CD-2/3 submittal package include all the activities necessary for both the CD-2 and CD-3 submission combined in the same submittal package. A CD-2/3 approval is particularly useful when pursuing design-build. 6. Post CD-2/Pre CD-3: Prepare for Construction Execution Start. a. Complete Project Design. After the Project Baseline is approved, the FPD completes the project definition/design, begins to execute the Acquisition Strategy, and initiates early procurements. b. Manage the Project Baseline. The FPD manages the project baseline by overseeing and evaluating the progress of the project through CD-4. The FPD evaluates performance against cost, schedule, and scope. NA-APM90 monitors performance through monthly meetings and invites representatives from the Appendix A NNSA SD 413.3 APA-6 05-18-21 Chg. 1 (Admin. Chg.): 09-18-24 Heads of NNSA Elements to attend to maintain situational awareness of project performance. c. The FPD updates the baseline in accordance with the change control thresholds in the PEP when there is a new requirement or a change to the cost, schedule, or scope. 7. Post CD-3/Pre CD-4: Prepare for Start of Operations or Project Completion. a. Award Construction Contracts and IAs. NA-APM90 or its agent awards construction contracts, work authorizations, and IAs to support project requirements. To ensure successful outcomes, close coordination is expected between contracting staff across the enterprise. b. Manage Construction Contracts and IAs. NA-APM90 or its agent oversees and manages construction services through contracts and IAs to achieve the project baseline. c. Manage Site Integration Issues. The FPD takes the lead role in managing any site integration issues, in support of construction activities, with the NNSA Elements, Nuclear construction projects must also comply with design safety requirements of DOE-STD-1189-2016, Integration of Safety in the Design Process. d. Prepare for Transition to Operations. In close coordination with Heads of NNSA Elements, the FPD is responsible for developing and managing startup, turnover, and closeout plans in accordance with DOE O 413.3. Activities include checkout, testing, and operations acceptance; completing a transition to operations plan; performing final project inspections; conducting a commissioning evaluation; and preparing for an Operational Readiness Review, a Readiness Assessment, or a Readiness to Operate Assessment. Heads of NNSA Element’s involvement in these activities is essential for project success. e. Establish Beneficial Occupancy Date (BOD). The stage of construction of a building or facility, before final completion, at which its user can occupy it for the purpose for which it was constructed. Beneficial occupancy does not imply that a project has reached CD-4. The BOD is the date that follow-on contracts/activities (if any) such as information technology or furniture installations may begin. For large projects there may be multiple BODs and the BOD does not replace CD-4. A construction schedule identifying the BOD is developed and used as the basis for establishing reasonable contract duration(s) at CD-2. The scheduled BOD is reviewed in conjunction with routine monthly project reporting and adjusted as required to reflect the best estimate for when the BOD actually occurs. Revisions

to the scheduled BOD must be reviewed and coordinated with the FPD and customer prior to being entered into the change control process. https://nnsaportal.energy.gov/intranet/na-apm/NA-APM-20/ShortCuts/DID-PRG-0001-CheckoutTestingandOperationsAcceptance.aspx NNSA SD 413.3 Appendix A 05-18-21 APA-7 Chg. 1 (Admin. Chg.): 09-18-24 8. Post CD-4: Prepare for Project Closeout. a. Accept Project for Operations. Heads of NNSA Elements verify the mission need and project requirements are met and accept the project for operation in accordance with the PEP. b. Turnover to Operations and Conduct Closeout Activities. Upon acceptance, the FPD continues to provide monthly project reviews with all IPT members until closeout activities are completed. This includes completing any punch list items, managing warranty issues, completing contracts/IAs, and conducting closeout activities. c. Project Closeout. The FPD prepares the project documents for PME approval, schedules the ESAAB or ESAAB-E, and officially closes the project out in the DOE Project Assessment and Reporting System. Also see BOP 413.8SD 413.3-6, Energy Systems Acquisition Advisory Board Equivalent (ESAAB-E) Process for more information on the ESAAB process.

APPENDIX C: DOE ACQUISITION MANAGEMENT SYSTEM FOR LINE- ITEM CAPITAL ASSET PROJECTS The DOE Acquisition Management System for Line- Item Capital Asset Projects Illustration is provided for context to explain NNSA’s Capital Asset Acquisition and Project Management process. THIS PAGE INTENTIONALLY LEFT BLANK NNSA SD 413.3 Appendix D 05-18-21 APD-1 Chg. 1 (Admin. Chg.): 09-18-24 APPENDIX D: CONCEPTUAL AND PRELIMINARY DESIGN GUIDANCE Conceptual and preliminary designs are key deliverables that provide essential feedback to the integrated project team (IPT) to ensure that the project meets requirements, fulfills the mission need, and is safely delivered on budget. Experience demonstrates that significant risks and opportunities are best managed during the process of conceptual and preliminary design development while the cost to implement change is minimal. The best opportunity to resolve applicable risks, which will allow for more accurate cost estimates and performance baselines, fewer cost increases, and minimal schedule delays, is early in the design process. Many of these typical project problems can be mitigated by providing sufficient funding for conceptual and preliminary designs. To better manage our capital line-item projects, the following implementation guidance is provided to standardize the deliverables for conceptual and preliminary designs. The goal of this implementation guidance is to provide consistency for the conceptual and preliminary design package deliverables. Following this guidance will ensures that the design of systems, structures, components, and other facility attributes are sufficiently mature for meaningful conceptual and preliminary designs and their associated cost estimates. This guidance also provides key cost relationships to ensure sufficient funding is provided to deliver Appendix D NNSA SD 413.3 APD-2 05-18-21 Chg. 1 (Admin. Chg.): 09-18-24 these design packages.

Conceptual Design Deliverables for Capital Line- Item Projects All deliverables are assumed to be based on best available information and unsuitable for issuance for final design, procurement, or construction. The degree of completion for the deliverables are defined as outlined below. • N/A – Deliverable is not applicable or required. • Conceptual – Work on the deliverable is not advanced with interim and cross-functional reviews typically completed. Often the deliverable is assigned an alpha revision number rather than a numeric revision number to designate that it is not under a formal configuration control system. • Complete – Work on the deliverable is complete and the final configuration has been reviewed (both intra- and inter-discipline) and approved. The deliverable is assigned a numeric revision number to designate that it is under a formal configuration management process because changes to the deliverable may result in major schedule and cost impacts. The deliverable will continue to be revised under a formal configuration management process as the design matures to 100%.

At BOD, there are typically punch list items and other minor construction activities remaining. The BOD will be the dateis when the project is officially transferred to the customer for occupancy and intended use, and for follow-on contracts/activities (if any) such as information technology and furniture installations. BOD is defined as substantial completion and/or when the facility or construction can be used for its intended purpose. For large projects there may be multiple BODs. The BOD does not take the place of Critical Decision (CD)-4 and in general is to be used to accept occupancy of specific facilities or portions of a large project. The following actions shallmust be taken to provide consistency of process across NNSA: 1. The designer of record shallmust develop a construction schedule prior to solicitation for all construction projects. The schedule shallmust be reviewed as part of the independent technical, biddability, constructability, operability, and environmental reviews of the final working drawings and specifications and be used as the basis for establishing reasonable contract duration(s) at CD-2. 2. The scheduled BOD will be reviewed in conjunction with routine monthly project reporting and adjusted as required to reflect the best estimate for when the BOD will occur. Revisions to the scheduled BOD shallmust be reviewed and coordinated with the Federal Project Director (FPD) and subsequently the customer prior to being entered into the change control process.
