Written by GovTribe AI · Apr 3, 2024

This document is Addendum No. 2 for the Marquette Branch Prison - Primary Electrical Infrastructure Upgrades project, issued by the Department of Technology, Management and Budget, State Facilities Administration, Design and Construction Division in the State of Michigan. The addendum provides clarification and responses to questions regarding electrical specifications, including information on panels, transformers, cables, and conduits. It also includes an electrical riser diagram with key notes on the new electrical system components. The project is funded under File #472/22442.JBB and involves upgrades to the primary electrical infrastructure at the Marquette Branch Prison facility.

The addendum provides details on the electrical equipment and cabling to be installed, including voltage ratings, amperage, number of poles, and conductor sizes. It confirms that the utility company will provide the transformer and base, and that the contractor will need to install new primary cables in conduit. The project appears to involve multiple buildings and electrical system modifications throughout the prison facility.
