may include temporary co-location.

1.3 Project Letting

The Project letting is June 23, 2026.

1.4 Project Scope

The project is primarily located in St. Louis County, Minnesota and Douglas County, Wisconsin between the cities

of Duluth, Minnesota and Superior, Wisconsin. The project limits extend 0.3 miles from the existing bridge

structure on the Minnesota approach to 0.75 miles from the existing bridge structure on the Wisconsin

approach, along US 53.

The project includes replacement of the existing John. A. Blatnik I-535 Bridge (Minnesota Bridge number 9030,

Wisconsin Structure B-16-5) on Interstate 535 (I-535) connecting Duluth, Minnesota and Superior Wisconsin

across the St. Louis River and Bay. The project also includes reconstructing an interchange in Superior, WI that

routes I-535 directly to US 53, with local connections to Hammond Avenue and WIS 35. The project includes

design and construction of a new mainline bridge (Minnesota Bridge number 69913, Wisconsin Structure B-16-

0153) and new exit ramp bridge (WI Structure B-16-0154) and entrance ramp bridge (WI Structure B-16-0155).

The new mainline bridge includes several bridge units:

MnDOT Contract No. 1061739

Exhibit C: Specifications, Duties, and Scope of Work

1. The Bridge Unit(s) for I 535 mainline portions from the abutment in Minnesota to the Main

Navigation Channel Bridge Unit

2. Bridge Unit of the Main Navigation Channel over St. Louis River,

Navigation Bridge Units

4. The Howard’s Pocket Navigation Channel Bridge Unit

abutment in Wisconsin.

The project includes a new shared use path on the easterly side of the new mainline bridge and Wisconsin

entrance ramp bridge with trail connections in Duluth and Superior, drainage improvements, retaining walls,

and improvements within the City of Superior. The existing bridge will be closed for most of the construction

and traffic will be detoured to the Richard I. Bong Memorial Bridge (US-2 over the St. Louis River).

Approximate Project cost: The estimated cost of the Project is between $1.0 billion and $1.4 billion.

MnDOT anticipates a minimum of three-year duration for this contract. State anticipates the work may

extend past 5-years, which may result in a subsequent contract being set up.

1.5 Verification Team Organization Chart

Exhibit C – Attachment 1 is the SBCOT organization chart and shows how the State will staff the SBCOT for this

project. It graphically shows the chain of command. It also shows how the Contractor staff described in this

contract interacts with the State staff.

WORKFORCE

Contractor will perform all work necessary to manage this Contract and its personnel. Contractor will perform all

specialty bridge construction oversight work necessary to assist with managing the DB Conformed Contract.

2.1 Flexible Workforce

Contractor personnel approved by the State’s Project Manager are considered by the State to be committed to

performing services for the durations listed in this scope of work. Any changes will require written approval

from the State’s Project Manager and include both adding additional staff and reducing staff.

No personnel will be assigned until written notification by the State’s Project Manager has been issued.

If the DB Contract is suspended for any reason, the Contractor’s forces will be adjusted to correspond with the

type of cessation, either complete or partial suspension. Contractor will continuously look ahead to fully

understand what type of staff are needed and in what numbers. The Contractor’s schedule will be dictated by

the DBC’s schedule. Contractor will provide a flexible work force so that only those staff that can be fully utilized

during any given project activity are present and billing hours to the contract.

MnDOT Contract No. 1061739

Exhibit C: Specifications, Duties, and Scope of Work

Contractor will continuously monitor all activity to verify that all work carried out is within the agreed scope and

completed with resources that can complete the work as budgeted. In the event it becomes necessary to

complete work outside the original scope of work, the Contractor’s Project Manager will notify State’s Project

Manager immediately before proceeding. No work outside the original scope will be done without written

authorization from State’s Project Manager.

Throughout the course of the Project, it may become evident that two or more Contractor roles would be more

efficiently staffed by a single qualified person. If this situation arises, the Contractor can make a request to the

State’s Project Manager to modify the staff by combining roles. The State’s Project Manager will evaluate the

experience and workload of the remaining staff member and will make a determination of whether the roles

should be combined. If multiple roles are allowed to be staffed by a single person, the State Project Manager

may reverse that decision at a later date, if circumstances call for more attention to those roles than the single

person can effectively handle.

Conversely, it is expected that the Contractor will have staff available to fulfill the obligations of each role

described within this contract. This may include rotating on-site staff to fulfill project needs, based on approval

by the State’s Project Manager.

2.1.1 Flexible Workforce - Project Support Staff

The Contractor will need to leverage additional project support staff, whether within their company or through

subconsultants, to assist the various roles on the SBCOT. The additional staff are expected to be available to help

with the task of reviewing plans and calculations, draft alternative designs/create quantities to counter claims by

the DBC, and use other software listed in this scope to evaluate products the DBC creates using that software.

2.2 Items Provided by the State

The State will not provide office supplies or office space for this Contract.

2.3 Items Provided by Contractor

Provide durable office supplies and reference material for their own employees as needed. Provide any office or

inspection verification supplies and reference material for their own employees as necessary to complete the

assignment to the project, together with detailed resumes with respect to education, experience

(including specific durations) and qualification of each individual. Minimum qualifications for the

Contractor personnel are set forth in this Scope of Work. State may require that these minimum

skills.
