Primary Suppliers

Designers and fabricators need not have prior experience with ground-based optical telescopes, but they should be experienced in the design and/or fabrication of precision equipment or large-scale instruments for scientific or high technology applications.

Secondary Suppliers

GMTO expects material suppliers and other secondary suppliers to be subcontracted by the first tier (primary) designers/fabricators in teaming or partnering arrangements. GMTO encourages such arrangements but will not be directly involved in making them.

No competitive advantage will accrue by teaming with GMTO Founder institutions or with companies located in GMTO Founder institution countries. The telescope will be procured through an open global competition with teams to be formed based on business decisions by the bidding parties, with no involvement or influence by GMTO.

After the Industry Briefing (see below) GMTO will make available the names of parties, with their permission, who returned an Expression of Interest form.
