REQUIREMENT: The Next Generation Very Large Array (ngVLA) is a project of the National Radio Astronomy Observatory (NRAO) to design and build an astronomical observatory that will operate at centimetre wavelengths. As a contribution to the ngVLA, the National Research Council of Canada (NRC) through its Herzberg Astronomy and Astrophysics (HAA) Astronomy Technology Program is undertaking to design the 6m antennas.

The current concept design phase of this study is to develop a design to sufficient level to determine if it is likely to meet the ngVLA requirements. A critical aspect is the surface accuracy requirement, operation at the highest frequencies requires the surface to be accurate to the design surface to within 160 microns RMS under operating conditions. Sources of distortion include wind, thermal, gravity and manufacturing errors. Manufacturing errors for a moulded composite part are governed by the mold accuracy and the Process Induced Distortions (PID). An estimate of the expected PID errors is a critical input to the overall error budget.  

This requirement is for the mold design. The behaviour of the mold is a key factor in the PID error analysis and therefore a conceptual mold design is required as input to the study.  The PID study may provide feedback to the mold design and so the mold design statement of work also includes a provision to iterate the mold design if required.

Additional design work, if required, to be completed using the Task Authorization process outlined in the contract.

The contractor will deliver:
First design iteration:
• A report describing the design features and materials details of the mold.
• A 3D CAD file of the mold in a portable file format such as STEP or IGES.
• 2-D drawings showing the overall mold concept with primary dimensions.
Second design iteration (if required):
• Updated design report.
• Updated 3D CAD file.
• Updated 2-D drawings.

PERIOD OF THE CONTRACT: All of the deliverables for the firm requirement must be received by December 31, 2019.  The period of the Contract is from date of award to October 31, 2020, inclusive.

TRADE AGREEMENTS: The requirement is subject to the provisions of the Canadian Free Trade Agreement (CFTA).

CANADIAN CONTENT: The requirement is conditionally limited to Canadian services.
