P8.3 Engineering Service for detailed design development — Ref. 626/2016/3451861

German Aerospace Center

DLR operates at their test centre near Lampoldshausen, Germany, several facilities for the purpose of testing liquid chemical propellant rocket engines in the frame of civil European Space programmes. One facility is test bench P8 with its test cells P8.1 and P8.2. The cryogenic supply systems work with high pressure.
A new test cell P8.3 should be erected, whereby there will exist some interfaces to the old test cell infrastructure. This test cell works with low pressure supply systems. Therefore specific attention is required concerning the design of the cryogenic supply systems.
Modifications, renewals and erections of test benches or parts of test benches are requested by DLR's customers or DLR itself. Such tasks require engineering activities in various technical fields, which follow a specific organisational and technical workflow.
The feasibility study is already completed and the preliminary design phase has currently been started. The PDR will be finished end of January 2017.
This tender is only for the development of the detailed design.
The other steps will follow in a later stage.
For the project management and detailed design development DLR is searching for an engineering company with the following proven minimum requirements:
— At least references of two comparable projects of test facilities for space propulsion with cryogenic supply systems of the last three years where a low pressure supply system was designed and the technical challenge of cavitation has been solved.
— Written declaration that experience in the organizational and technical workflow (from Preliminary design phase until acceptance) is available.
— Written declaration that there is enough manpower in order to finish the detailed design within four months beginning in February 2017.
— Written declaration that there is sufficient knowledge of German language available in order to understand safety instruction in German.
— Written declaration that there is sufficient knowledge of English language available in order to prepare all documents in English.
— Certified according DIN EN ISO 9001.
— Turnover of the last 3 years.
— signed NDA.
PD Phase in detail:
After award of contract
— Analysis of the PDR documents supplied by DLR. These are
o Edition 1 of project/development plan.
o Technical report of Preliminary Design Phase results.
o Problem Analysis Sheets (PAS) from the key-point meeting.
o Updated actions list status after PDR (including actions from PAS).
o Long lead items list for early purchase.
— Establishment of a list of open points and questions.
— Technical clarification of ambiguities with DLR and its customer.
— Verification of the local conditions on site if necessary or wished.
— Organisation of a kick-off meeting (and Minutes of Meeting of kick-off) done by DLR, if DLR or the contracted company recommend such a meeting.
o Preparation of the presentation for the kick-off meeting (DLR template).
o Participation in the kick-off meeting.
Kick-Off-Meeting or Telecon
The DD phase can be formally started by a face-to-face kick-off meeting with the following agenda, as far as the contracting parties recommend a formal meeting (DLR's customer might attend):
— Presentation of aim of the project and elements of the specifications by DLR Presentation of draft schedule and cost estimation by DLR
— Presentation of analysis of PD documents by the engineering entity
— Introduction of involved personnel and entities, communication interfaces
— Further organisational and technical constraints/conditions
— On-site visit, if necessary
— Clarification of open points, discussion
— Definition of key-point dates (CW accuracy), date for next key-point, Definition of very next activities
Output Documents:
— Minutes of meeting with presentation(s) attached
— Updated actions list status.
If no meeting will take place relevant points shall be discussed within a telecon
Detailed Design Phase
In the detailed design phase all documents are created, which are needed to justify the details of the design of the erection and its operation, within the realm of the facilities nominal operation.
The structure of the set of documents is done in a way that allows using individual documents for the tender phase, i.e. technical specifications shall be done for each later tender lot. Further documents shall be created if required, and it shall be possible to start tender activities with the results from the detailed design phase.
At the very beginning of the detailed design phase, those long lead items shall be specified in detail, which were decided to be ordered in advance.
The activities within the phase are:
— Treatment of actions and PAS resulting from PDR
— Finalisation of the technical solution chosen in the PDR
— Refinement of schedule and cost estimation ±10 %
— Conclusion of compliance matrix for the investigated solution(s) versus the specification
— Final Interfaces catalogue
— Finalization of project/development plan and establishment of technical document(s) (work breakdown structure, acceptance logic, management risks, technical risks, other safety aspects, tender logic including DLR-activities, status of long lead items and operation aspects)
— Preparation of the document(s) for the CDR (available 1 week before the CDR).
— Organisation of CDR and Minutes of Meeting of CDR done by DLR.
— Preparation of the presentation for the CDR (available 1 week before the CDR).
— Participation in the CDR meeting.
— Establishment of technical specifications for all tender lots (1 per lot).
— Establishment of acceptance tests specification.
— Update of action database.
— Treatment of actions and PAS from the CDR, update of documents, if necessary.
Critical Design Review
The results of the detailed design phase shall be presented on a Critical Design Review (CDR), which shall be a face-to-face meeting (DLR customer might participate) with the following agenda topics:
References
List of documents created in the detailed design phase
Status of actions and PAS from PDR
Presentation of the technical specification for each tender lot (overview)
Refined schedule and cost estimation (separation of activities into tender lots to be taken into account)
Final interface list for all concerned technical realms (civil works, electrical power supply, measurement/command/control, piping, etc.)
Final work packages presentation, including technical work packages to be treated by DLR
General task description for all work packages to be treated by DLR
Presentation of compliance with the specified technical characteristic of the erection
Presentation of acceptance plan,
Presentation of technical risk analysis,
Presentation of operational and management risks,
Presentation of Safety aspects,
Tender logic, also indicating DLR activities,
Status of long lead items purchase, if any
PAS creation by review group
PAS answering by project group
Presentation of answers and decision about status of PAS
Conclusion, verbal acceptance of the detailed design phase
Definition of further key-point dates (CW accuracy), Definition of very next activities
The participants in the Critical Design Review are assigned to two teams/working groups, the project group and the review group. The project group defends the presented technical results, while the review team challenges these results through questions which are provided through so called ‘Problem Analysis Sheets’. The response of the project group is noted on these ‘Problem Analysis Sheets’. The Critical Design Review is conducted and moderated by a dedicated Chair-Person. For the sake of simplification the Chair-Person can decide, in coordination with DLR's customer, to convert this PAS procedure into a normal discussion with definition of dedicated actions.
After the CDR, the open actions at this time (also and in particular actions from PAS) will be treated and documents will be updated, if necessary.
