Context and Background

The Town of Shelburne proposes to replace a large-diameter culvert located at the South Park Road

crossing of McCabe’s Brook, whose structure is considered high risk. South Park Road, which is

classified as a class 3 town highway, provides primary access to Shelburne’s industrial park and is a

vital transportation corridor supporting daily employee traffic, freight deliveries, and emergency service

access. Constructed in 1994, the structure consists of a 13’-3” wide, 9’-4” high CSPA multi-plate bolted

construction culvert with associated reinforced concrete headwalls, wingwalls and apron system. The

stream conveyance under the roadway embankment is 113 feet in length and the existing structure is at

its mid-to-late service life.

Due to age, ongoing hydraulic loading and repeated storm events, the structure is exhibiting serious

signs of deterioration and reduced hydraulic efficiency and is assessed at a high risk of collapsing.

Additionally, the structure was designed to standards and rainfall assumptions that pre-date current

understanding of storm intensity and frequency. Among other vulnerabilities, the structure displays

localized heaving of the culvert invert, substantial invert deterioration, groundwater infiltration, erosion

at the inlet and outlet, and displacement of stone fill, resulting in the formation of a plunge pool

extending approximately 3 feet below the culvert channel invert. Failure or impairment of the culvert

would significantly disrupt business operations and local economic activity.

Earlier in 2026, the Town commissioned an engineering firm, to undertake a site inspection of the South

Park Road culvert and to present an alternatives analysis for rehabilitation/replacement of the culvert.

The report and alternatives analysis can be found at the link below:

The Town anticipates replacing the existing structure with a likely bottomless box culvert that will need

to meet current engineering, environmental, and regulatory standards.

Scope of Work and Deliverables

Fee Proposal

The budget for this project is $80,000 to provide professional engineering and permitting services for the

replacement of the existing large-diameter culvert located at the South Park Road crossing of McCabe’s

Brook.

The consultant should provide a detailed, itemized fee proposal for all engineering services to include (i)

schematic, preliminary and final design and (ii) permitting.

The fees to be paid shall remain valid for the duration of the satisfactory completion of the contract and

shall represent the consultant’s complete cost to perform the scope of services described in this Request

for Proposals.

Proposal Submission Requirements

Proposals must include the following information:

• Cover letter introducing the firm and summarizing qualifications

• List of project team members with qualifications, resumes, and professional registrations

• Description of firm’s experience to include a strong civil engineering background with direct

experience in culvert and drainage projects

• Examples of similar projects completed, including before/after photos where available

• Proposed methodology and approach to the project, including suggested project timeline

• Detailed cost proposal broken down by tasks

• Hourly rate schedule for work outside the scope of this request

• Professional references from at least three recent similar projects

• Evidence of professional liability insurance

Proposals shall provide evidence of demonstrated successful proven experience in culvert design,

drainage systems and roadway infrastructure projects. Ability to assess soil conditions, load-bearing

capacity and water flow characteristics for culvert foundations and performance is highly desirable.

Experience with relevant state agencies and Vermont’s River Management Program is an added benefit.
