1. Description of Tasks
1.1 Supply Description
1.1.1 Telescope M1 Mirror Covers
The supply includes: the construction and assembly of two folding Mirror Covers which protect the two 8.4 meter diameter primary mirrors of the Large Binocular Telescope.
Each Mirror Cover assembly consists of a swing arm with a rotation mechanism to move it “in” and “out” of the M1 mirror axis; and on the swing arm a circular deployable umbrella is supported along with an electromechanical device to "open" and "close" it on the M1 mirror area. The M1 Mirror Cover must be able to be opened and closed in every position, between 0 and 90 degrees, of the elevation structure of the Telescope.
The supply consists of one pair of complete Mirror Covers with a right- and left-handed configuration. Our drawings show the right-hand swing arm.
In detail the supply includes:
- Preparation of the workshop drawings (structural, mechanical and electrical) starting from the assembly drawings provided by LBTPO.
- Manufacturing of all mechanical and electrical parts that make up the Mirror Cover swing arms, the rotation mechanisms and the deployable umbrella.
- Purchasing of all the commercial parts.
- Pre-assembly of the Mirror Cover arms.
- Functional tests in the factory of the entire assembly.
- Final Painting and disassembling for packing.
- Assistance for packing.
The M1 Mirror Cover attaches to the front of the already existing M1 Cell. The M1 Cell structure is not included in this supply.
1.1.2 Technical Specifications
The hardware will be manufactured in accordance with the Large Binocular Telescope Project's Technical Specification "401a022", entitled "Rotating Supporting Arms with the fabric retractable cover of the Primary Mirrors", revision "d", dated February 26, 2004 and in accordance with the applicable drawings listed below. These drawings represent a quite detailed concept; however we assume that the Supplier will produce their own detailed fabrication drawings which incorporate local best practice and procedure.
1.1.3 Delivery Date
The preferred delivery date for the Mirror Covers is November 22, 2004.
The proposal should include a timeline of the Supply of all activities not including packing and shipment.
1.1.4 Shipping
The Supply does not include packing and shipping of the assembled Mirror Covers. The packing and shipping of the Mirror Covers may be included as an option in the proposal.
