Release of Draft Request for Proposal for Primary Mirror Segment Gravity Performance Verification

The TMT Project (TMT) is preparing a request for proposal (RFP) for the measurement and analysis of gravity-induced deformation of the optical surface of a prototype primary mirror segment (the “Work”). It is anticipated that this will be a competitive procurement. Currently, TMT is offering an opportunity for interested organizations to review the draft RFP and provide feedback with the objective of further refining it.

The release of this draft RFP is not a solicitation or an offer of contract. Please note that issuance of this draft RFP does not require TMT to release an RFP or award a contract. TMT is only requesting comments and suggestions on the draft RFP to enable a successful procurement. Therefore, the terms and conditions of the draft RFP are not final and are subject to change at the sole discretion of TMT.

For the draft RFP review, TMT welcomes each respondent to offer format and content improvements. Respondents should also feel free to submit questions and comments on any aspect of the draft RFP.

As part of this draft RFP review, TMT asks that all respondents specifically address the following:

1. Schedule durations are left as TBD in the draft RFP. Based on the contract start date and the availability date of the test article (P2 prototype segment provided by TMT), provide schedule estimates to fill in the TBDs that would work well for your organization.

2. With the testing method envisioned, what magnitude of initial surface figure error in the test article can be tolerated while still enabling the required testing accuracy?

3. With the testing method envisioned, estimate the dynamic range of the measurement.

4. Are there changes to the requirements that would simplify the task, but still enable achievement of the desired deliverables?

5. What measurement repeatability is required to enable achievement of the desired deliverables?

6. How would the repeatability affect the accuracy of the potential follow-on measurements described in Section 7 of the RFP?

7. Are there tasks in the statement of work that can be simplified or eliminated to reduce cost, but still enable the achievement of the objectives?

Respondents are also encouraged to review additional information about TMT on our website:

Responses to this draft RFP review should be submitted to Pratheep Eamranond at by 5:00pm (Pacific Time) on September 3, 2009 for proper consideration.

TMT reserves the right to reject any and all draft RFP responses.

Respondent's proprietary information must be clearly marked in accordance with the terms contained in TMT’s standard non-disclosure agreement. TMT’s standard non-disclosure agreement is attached to the draft RFP as Exhibit E. Failure to execute an non-disclosure agreement will not obligate TMT to consider or protect respondent's data except as otherwise required by law or regulation. Any information subject to export controls must also be clearly identified.

On behalf of TMT, I want to extend our thanks for your interest in our Project and I look forward to your responses.
