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 design is an Offset Gregorian Feed-low Antenna based on NRC’s Single-piece, Rim supported Composite (SRC) reflector technology.

The current phase of this study; concept design 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. The latter of these is the focus of this Statement of Work (SOW). Manufacturing errors for a moulded composite part are a governed by the mould accuracy and the Process Induced Distortions (PID). An estimate of the expected PID errors is a critical input to the overall error budget.

NRC requires a contractor to simulate the manufacturing induced distortion on the primary reflector of the ngVLA 6m, including geometry changes both in the part and in the mold. The contractor will be required to quantify the expected effect such that corrections can be made to the mold shape to compensate for this effect.

PERIOD OF THE CONTRACT: All of the deliverables for the firm requirement must be received by May 29, 2020. The period of the Contract is from date of award to March 31, 2021, 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. The evaluation team will determine first if there are three or more bids with a valid Canadian Content certification. In that event, the evaluation process will be limited to the bids with the certification; otherwise, all bids will be evaluated. If some of the bids with a valid certification are declared non-responsive, or are withdrawn, and less than three responsive bids with a valid certification remain, the evaluation will continue among those bids with a valid certification. If all bids with a valid certification are subsequently declared non-responsive, or are withdrawn, then all the other bids received will be evaluated.

DEBRIEFINGS: Bidders may request a debriefing on the results of the bid solicitation process. Bidders should make the request to the Contracting Authority within 15 working days from receipt of the results of the bid solicitation process. The debriefing may be in writing, by telephone or in person.

IMPORTANT: This tender is part of Public Works and Government Services Canada’s initiative to submit bid submission files electronically using epost Connect. Interested bidders should refer to Part 2 of the solicitation document entitled Instructions to bidders/offerors/suppliers, as the case may be, for instructions on how to participate and submit their files electronically for this tender. Further specifications and information are contained in the solicitation package.
