Walker South

Brief Description: MnDOT requests proposals for a phased contract including geometric layout and 30% plan completion (Phase 1) with potential of adding final design (Phase 2). The project Area is located on Trunk Highway (TH) 371 from the south unction with TH 200 to the City of Walker. This project will consist of a reclaim, with reconstruct segments where large changes to the profile are made, two new roundabouts, replacement of roadside infrastructure in poor condition, a center buffer zone or a Two Way Left Turn Lane through the whole road segment, and a new trail segment. Roadway widening will be required to accommodate the addition of the buffer zone and extend the Two Way Left Turn Lane. The primary goal of this project is to utilize alternatives identified from a previous TH 371 corridor study to arrive at an approved layout and 30% plan completion (Phase 1).

1. Project Overview

State Project (SP) 1119-43: TH 371 Walker Rural Reconstruction — From E. Jct of MN 200 to the

southern limits of Walker, approximately 4.16 miles.

1.1. Independent Contractor

The Contractor agrees it is acting in the role of an independent contractor. The Contractor, and its

employees and subcontractors, will not be considered employees of the State for any reason. The

Contractor acknowledges that it is responsible for its own financial control. The Contractor has negotiated

the payment for this contract with the State, which may result in a profit or loss for the Contractor. The

Contractor also acknowledges that it is responsible for the behavioral control of itself, its operations, and

its staff. The Contractor is solely responsible for determining the means, methods, and sequence of

MnDOT Contract No.

Exhibit C: Specifications, Duties, and Scope of Work

performing the work covered by this contract. The State has included deliverable dates in this contract,

not to provide a “sequence” of work but because the State must coordinate these deliverables with (1)

the State’s financial plans, (2) other contracts managed by the State, and (3) work performed by the

State’s own staff. The parties have mutually drafted and agreed upon a scope of work. The level of detail

used to describe the work is intended only to establish minimum standards and ensure consistency across

the hundreds of projects managed by the State; the Contractor remains responsible for determining the

means and methods of performing the work to meet or exceed those requirements. The State will not

directly supervise the Contractor’s work but will provide oversight and monitoring, as required by

Minnesota Statutes §16C.08 and 23 CFR Part 172.5, to ensure compliance with the terms, conditions, and

specifications of this contract. At the conclusion of this contract, the State will evaluate the Contractor’s

performance under this contract for potential use in future evaluations and selections as required by

Minnesota Statutes §16C.08 and 23 CFR Part

1.1. General Statement of Scope of Work

1.2. This project is part of the MnDOT District 2 Rural Reconstruction program and integrates

recommendations from the 2024 Corridor Study, and MnDOT Rural Scoping Report. The

project aims to improve safety, pavement quality, multimodal access, and drainage

infrastructure in the rural segment south of Walker.

1.3. Key components in this Scope of Work that the contractor should be aware of:

a. The State will submit all permit applications for this project; However, the Contractor

will still be responsible for the Stormwater Pollution Prevention Plan and Erosion

Control sheets. The Contractor will still be involved in Agency coordination

discussions. See Section 12 Hydraulics of this scope for more detail.

b. The contractor shall prepare the Div S, DIV ST, DIV SS, and DIV SL portions of the spec

book. The City of Walker will prepare the Municipal Item Special Provisions

(Water/Sewer).

c. The State will handle Right-of-Way acquisition, titles and appraisals for this project.

d. There is a Visual Quality Management section of this scope that the Contractor will

be responsible for. However, given the variation we see from project to project on

this topic, it has been baselined with a set number of staff hours. See the Visual

Quality Management section for more information.

e. The project termini included in this Scope of Work do not match the limits of the

previous Corridor Study. We are only designing a portion of the corridor study limits

with this project. This project will tie-in on the South End of State project SP1119-42.

f. MnDOT is expecting the project to span two construction years. The consultant will

do the Time and Traffic to facilitate staging and construction years. Final staging has

not been determined as of the advertising of this RFP

g. The State will perform all field work and analysis to prepare the Foundation Analysis

and Design Recommendation (FADR) and the Material Design Recommendation

(MDR).

h. The project is located near Leech Lake Band of Ojibwe Tribal land, and the Consultant

should maintain a strong commitment to effective communication with the Tribal

community.

1.3.2. Key elements include:

a. Reclaim and resurface the roadway with targeted reconstruction where vertical

profile adjustments are required.

Exhibit C: Specifications, Duties, and Scope of Work

b. Construction of two single-lane roundabouts at MN 371/MN 200 and MN 371/Tower

Avenue-Walker Bay Blvd S, subject to MnDOT layout approval.

c. Corridor safety upgrades including a striped median buffer and a two-way left-turn

lane (TWLTL) where warranted; standard 12-foot travel lanes per District 2

preference.

d. Replacement of deteriorated centerline and side culverts, stormwater treatment if

more than one acre of new impervious surface is created.

e. Guardrail replacement strategy at Shingobee causeway (north side to remain cable

guardrail) with a goal of minimizing new guardrail installation unless necessary for

safety or environmental constraints.

f. Multimodal trail connections and access improvements consistent with local planning

and available funding.

g. These improvements are designed to extend pavement life, enhance traffic

operations, and maintain environmental stewardship while accommodating all users

along the rural corridor.

1.4. Project Background

1.4.1. There was a corridor study that was recently completed. This project will tie-in on the

South End of State project SP1119-42. That study information can be found here: Hwy 371

and Hwy 34 — Walker | Let's Talk Transportation - MnDOT

As part of this corridor study that was completed, a preferred alternative was developed in

partnership between MnDOT and the City of Walker. The Walker City Council approved the

preferred alternative with a “Motion of Support” in the summer of 2024.

1.5. Requirements for Work Within Right-of-Way

Minnesota Manual of Uniform Traffic Control Devices (MMUTCD) chapter 6D and

layouts in chapter 6J.

b. Notify the State if roadways, property access, legs of intersections, or pedestrian

traffic cannot be maintained. The State will then coordinate closures with the

equal or better condition than before excavation. The Contractor is responsible for

the integrity of the backfill/surface restoration. If the work site is not appropriately

restored, the Contractor must return and properly restore the site at no extra cost to
