About this file
This document is an Addendum No. 3 issued by the Michigan Department of Technology, Management and Budget State Facilities Administration Design and Construction Division for the Marquette Branch Prison - Primary Electrical Infrastructure Upgrades project, file #472/22442.JBB. The addendum provides clarifications and responses to questions related to the project, including the requirement for the Electrical Contractor to review the existing ground penetrating radar (GPR) survey and provide additional surveys as needed. It also provides details on the location and configuration of the new DP-L panel, as well as modifications to the electrical riser diagram and key notes. The project involves upgrading the primary electrical infrastructure at the Marquette Branch Prison, including the installation of new primary cables, switches, transformers, and electrical panels in the Central Kitchen and Programs Building areas.
The addendum includes pricing and funding details, such as the capacity and configuration of the new transformers, as well as the electrical feeder sizes and conduit requirements. The project is funded by the State of Michigan and is part of the Marquette Branch Prison's maintenance and infrastructure improvement program.

This Addendum is issued for the purpose of modifying and/or clarifying the original Contract Documents and shall take precedence over them.
All work included herein shall be in accordance with the original drawings and specifications except as specifically noted herein. All incidental items required to provide the following modifications shall be included even though not specifically described.
This addendum is being sent to all bidders receiving plans and specifications. Receipt of this Addendum shall be noted on the Bid Summary in the appropriate location.
Clarification and Questions:
A3.1 Question: Is the EC to provide GPR survey per drawings, I thought this was already done by TriMedia?
Response: The EC is to review the GPR that was provided by TriMedia and if there is any area outside of what they provided that you plan on doing any work then you will need to provide it for those areas.
A3.2 Question: Can you please provide the location of this J-Box on the site drawing?
Response: See sheet E-503 detail #6.
ADDENDUM NO. 3
A3.3 Question: Please clarify what is happening for the Programs building. The site drawing does not match the oneline. It looks like the site drawing shows a transformer that is not on the oneline. Is panel DP-L located on the 4th floor where the transformers are being removed?
Response: See attached sheet E-505, E-605.
A3.4 Clarification: Additional information on panel “DP-L”.
480V-3PH, 400 Amp, 4 wire, MLO 42 circuit panel with the following breakers:
