1. Description of Tasks

1.1 Supply Description

1.1.1 Embedded Beam and Circular Rail

This Statement of Work includes the manufacture of the Circular Rail and the Embedded Beam for the Large Binocular Telescope enclosure. The Embedded Beam is located on top of the the enclosure ring wall and provides the support/interface for the runway (Circular Rail) of the rotating enclosure of the telescope.

Due to the size of the assembled hardware (23 meters diameter), both the Embedded Beam and the Circular Rail will be fabricated in sections. The Embedded Beam will be made of structural steel plates, welded and bolted together. The Circular Rail will be made of rectangular steel rail welded to a steel baseplate. The Rail will need to be leveled, circularized and bolted to the Embedded Beam after the beam has been grouted in place on the concrete ring wall.

The Supplier shall furnish the necessary administrative, engineering and technical support to fabricate, assemble and perform verification testing prior to packing for shipment of the Embedded Beam and Circular Rail.

1.1.2 Technical Specifications

The hardware will be manufactured in accordance with the Large Binocular Telescope Project's Technical Specification "270e500", entitled "Enclosure Structure Embedded Beam and Circular Rail", revision "a", dated 09 May 1997; and in accordance with the applicable drawings listed below.

1.1.3 Delivery Date

The preferred delivery date for the Embedded Beam is 1 November 1997 and for the Circular Rail is 1 February 1998.

1.1.4 Shipping

Transportation of the components to Safford, Arizona is included in this Statement of Work.

1.1.5 Technical Assistance during Erection

Technical assistance during final installation in the LBT enclosure on Mt. Graham is not included in this Statement of Work, but the LBTC reserves the right to negotiate for such services at a later time.

1.3.4 Progress Reports to the LBTC

Reports on the status of the work covered by this contract should be sent to the LBTPO every three months. The Progress Report shall include an update of the initially proposed schedule (section 3.6.1 of the Proposal format).

2. Procedures

2.1 Acceptance

The Work shall be conditionally accepted by LBTC upon delivery and completion of the Work in a manner at that time satisfactory to LBTC. Final acceptance will be made subsequent to the installation into the Large Binocular Telescope structure or after a time not to exceed 120 days.

2.2 Technical Liaison

The Supplier shall provide access to all phases of each task in this Supply to the appropriately designated LBTC representative(s). The designated Technical Representative(s) is (are):

(to be defined for each package at the time of contract award.)

The Supplier shall maintain informal technical liaison with the LBT Project Technical Representative(s). These representative(s) shall be provided the following:

All workshop drawings regarding fabrication and construction must be submitted to the LBTC Technical Representative for approval before purchasing any materials and/or beginning any construction.

LBTC approval will cover only the functional and conceptual aspects of the design and will not cover the correctness of the dimensions and practicality of the machining. Approval of the drawings shall not indicate acceptance of the Work.

2.3 Technical Changes

All ECRs, NCRs, and Requests for Waivers or Deviations will be presented to the Technical Representative(s) for further evaluation, formulation of responses, and recommendations to the LBT Director.

2.3.1 Engineering Change Request

In the event that the Supplier deems it necessary to deviate from any specification or term of the Technical Specifications or the Proposal, the Supplier shall deliver to the Technical Representative(s) an Engineering Change Request (ECR) setting forth:

2.3.2 Non-Conformance Report (NCR)

The Supplier shall report all non-conformities from the Technical Specifications which occur during the manufacture, assembly, or testing at all levels of the Work. Each Non-Conformance-Report shall set forth the following:

2.3.3 Request for Waiver/Deviation

A Request for Waiver may be issued during the manufacturing, test or integration of a deliverable item to:

A granted waiver does not lead to changes of any approved and released documents. The Request for Waiver shall include:

It shall be accompanied by all documentation required by the LBT Corporation to judge the acceptability of the waiver. If any change in the schedule or performance are expected, these points shall be clearly addressed.
