Preliminary Design Review (PDR) Clause Samples
The Preliminary Design Review (PDR) clause establishes a formal checkpoint in a project where the initial design concepts and plans are evaluated for feasibility and alignment with requirements. Typically, this review involves presenting design documents, schematics, and analysis to stakeholders or clients for feedback and approval before proceeding to more detailed design phases. By requiring this early assessment, the PDR clause helps identify potential issues, ensures that the project is on the right track, and reduces the risk of costly changes later in the development process.

Preliminary Design Review (PDR). The System PDR shall be conducted to allow the Contractor to satisfy Inmarsat formally of the baseline design concept and the planned implementation. This meeting shall include reviews of the appropriate budgets and specification requirements for system, subsystem and unit level and shall verify compliance with the contract requirements. This PDR shall also establish the compatibility of the design with the external and internal interfaces (Launch Vehicles, GSID, SDID etc). In view of the fact that the Platform is already qualified, the Platform aspects of the System PDR should actually be at CDR level. For new equipment, PDR’s shall also be held at Subsystem and Equipment level to satisfy Inmarsat of the baseline design concept, configuration, specification and design for that item. These PDR’s shall include a Specification Traceability Review to establish the link back to the overall system level requirements. For equipment which has already been qualified on other programmes and which is to be used unchanged on Inmarsat-4, the PDR, CDR and MRR shall be combined into a single review in order to authorise the start of manufacture for new equipment as early as possible in the programme. For off-the-shelf equipment, the PDR and CDR shall be combined with the TRB to verify its acceptability for the programme. The PDR will be deemed to be complete upon the completion and acceptance by Inmarsat of resolution of major action items. Sub-system reviews may be combined with system level design reviews.
Preliminary Design Review (PDR) a. The Preliminary Design Review (PDR) demonstrates that the preliminary design meets all system requirements with acceptable risk and within the cost and schedule constraints and establishes the basis for proceeding with detailed design. It will show that the correct design option has been selected, interfaces have been identified, and verification methods have been described.
b. PDR occurs near the completion of the preliminary design phase.
Preliminary Design Review (PDR). The purpose of the PDR is to allow INTELSAT and the parties responsible for the item under review to agree on the baseline concept, configuration, specifications, and preliminary design of that item. The design review package shall be submitted in accordance with the CDRL (Appendix 2, Section 2.3.1). INTELSAT shall have the right to approve the review in accordance with 3.
Preliminary Design Review (PDR). The PDR demonstrates that the preliminary design meets system requirements with acceptable risk and within the cost and schedule constraints and establishes the basis for proceeding with detailed design. Amount: $23.5M Date: November 2024
Preliminary Design Review (PDR). The contractor shall conduct a Preliminary Design Review in accordance with SECTION H-4 (a) of this contract. The government may provide additional guidance prior to this review.
Preliminary Design Review (PDR). The purpose of the PDR is for the Contractor to demonstrate to the Government that the integrated baseline of the MK 48 MOD 7 APB6/TI-1 program is operationally effective and that it has accomplished adequate design planning without incurring unacceptable risks that could breach schedule, performance, cost or other established criteria. The Contractor will schedule the PDR within 10 days of being notified by the COR to proceed with the review. The Contractor shall coordinate with the Government when/where the review will be held.
Preliminary Design Review (PDR). The Contractor shall host a Preliminary Design Review (PDR) at the Contractor’s facility using the Defense Acquisition Guidebook, Paragraph 4.2.12 as guidance not later than seventy-five
Preliminary Design Review (PDR). 11.2.1. A detailed preliminary design review (PDR) shall be held at MCF,▇▇▇▇▇▇ within two months from Effective date of contract (EDC)/Award of Contract.
11.2.2. The PDR will be the first major review of the detailed design after order and the design shall be submitted within two months of signing the contract/Purchase order (PO) date.
11.2.3. The PDR shall discuss, among others, system engineering aspects, ground station configuration design, the installation plan & methodology, operations plan, test & measurement plan, acceptance procedures and plans, etc.
11.2.4. This review shall address the high-level design of the system, mapping the system requirements to a preliminary System Description Document (SDD). The SDD shall be delivered in book form (03 copies) & also in softcopy at least two weeks before PDR. The venue of PDR shall be preferably MCF, ▇▇▇▇▇▇ or mutually agreed upon place. The SDD shall, at a minimum include:
i. System Overview.
ii. General architecture with proposed hardware and software modules at a high level.
iii. Design considerations and design details of major subsystems like antenna pedestal/foundation design, antenna mechanical systems consisting of mount, reflector, sub-reflector, cable wrap, antenna servo drive, feed, electronic systems, etc shall be discussed during PDR.
iv. Analysis on wind torque, drive torque, stiffness, locked rotor frequency analysis of antenna structure including mount, reflectors, quadripod/ tripods etc.
v. Performance analysis of major requirements and specifications like G/T, EIRP, pointing accuracies, tracking accuracies, surface accuracies, efficiency etc.
vi. Material specifications, mass properties, inspection and testing.
vii. Complete Mechanical details (FE Analysis for antenna assembly and support structure against RF specification, & Racks dimension, Housing details etc.).
viii. Safety and security engineering considerations including stow-lock, ladders, limits, brake system, lightning arresters etc.
ix. List of deliverables including document x. Detailed activity including major milestones.
