1. SCOPE

1.1. Scope. The purchase description set forth below describes the minimum requirements of the

Government for a Maintenance Enclosure. It is the Government’s intent that a single primary contractor be awarded this contract and be responsible for the provision of equipment, and the accomplishment of all work detailed by this specification.

1.2. Purpose. The Maintenance Enclosure will be utilized to provide weather and visual protection while providing maintenance on equipment worked on by C/120. The Enclosure will be placed upon a Government Provided Yard Craft, which will be the floor. Then Enclosure shall have no floor. The enclosure shall include lights. The Enclosure shall be liftable by a crane with the max capacity of 30,000 lbs. The Enclosure shall be designed and constructed to provide a covered clear space envelope with no internal interferences (i.e. cross cabling, diagonal pipe bracing, pillars, etc.). The roof shall be designed to open to provide full unobstructed access to the interior. The roof shall be designed to have lift points with a total Working Load Limit of 1,000 lbs while closed. The enclosure shall be designed with the ability to route service equipment into the enclosure without compromising the weather and visual protection.

2. REQUIREMENTS
