1. Description of Tasks

1.1 Supply Description

1.1.1 Central Derotators' Structure

This Statement of Work covers the manufacture of the Central Derotators' Structure for the Large Binocular Telescope. These are the sections of the telescope elevation structure which support the central three pairs of focal stations and which support the bearings for the instrument derotators at each of these focal stations. The Supply includes: the preparation of shop drawings, the fabrication, the machining, the pre-assembly and the testing of the steel structure.

1.1.2 Technical Specifications

The hardware will be manufactured in accordance with the Large Binocular Telescope Project's Technical Specification "401e031", entitled "Derotators' Structure Support", revision "b", dated 19 January 1998; and in accordance with the applicable drawings listed below.

1.1.3 Delivery Date

The preferred shipping date for the Central Derotators Structure is 15 June 1999.

The proposal should include a time line of the Supply activities.

1.1.4 Shipping

Packing for shipment is included in the Supply. Tranportation to the Telescope Pre-Erection site is also included in this Supply.

1.1.5 Technical Assistance during Telescope Pre-Erection.

The Pre-Erection of all major telescope components will be required at a "to be determined" location before erection of the telescope on Mt. Graham in Arizona. This method has been selected to ensure proper form, fit and functional operation of each and every component of the telescope, before crating and shipment to Arizona. The Pre-Erection activities have been described in general form in the Technical Specification "401e028" , entitled "Telescope Pre-Erection".

Technical assistance during Pre-Erection of the telescope at the "to be determined" factory location or during final installation on Mt. Graham is not included in this Statement of Work. The LBTC reserves the right to negotiate for such services at a later time.
