REQUEST FOR BID
MITCHELL BROOK ROAD CULVERT No. 9
REPLACEMENT PROJECT
TOWN OF NORWICH, VERMONT
Issued: January 14, 2026
Project Location
Culvert No. 9 is located on Mitchell Brook Road in the Town of Norwich, Vermont and is to be
replaced with two culverts as detailed in the “Mitchell Brook Road and Chapel Hill Road Culvert
Assessment” in Attachment 1. The longitude and latitude are 43.757500, -72.385600.
Project Description (Existing Conditions)
Existing Culvert No. 9, as described in the attached hydraulic report, is extremely undersized and
needs to be replaced with two new culverts. The existing culvert No. 9 is a round, 24-inch diameter
steel culvert that is approximately 30 feet in length and in fair condition.
Project Work to be Completed and Project Specifications
Culvert 9 will be replaced with two new culverts as follows:
1. A new culvert will be required to handle the ditch conveyance and is to be a 30-inch corrugated
metal pipe (CMP). This pipe is to be an aluminized metal pipe with a minimum 12-gauge
thickness. The culvert will be approximately 35 feet in length.
2. A new culvert will be required to handle the intermittent stream that comes off the hillside from
the northwest and will require a separate CMP with a minimum 87-inch x 63-inch pipe arch
providing 32 square feet of waterway area or similar. This pipe is to be an aluminized metal
pipe with a minimum 10-gauge thickness. The culvert will be approximately 35 feet in length.
The existing metal Culvert No. 9 will be excavated, removed, and disposed of by the contractor.
It is to be noted that there is bedrock (ledge material) in the area and was observed to be
directly under the existing culvert. Removal of this bedrock material will likely be required
for the new culvert installations.
Existing backfill will be removed from the trench excavation site by the contractor. Trench bottoms
containing bedrock, soft muck, refuse, or other material unable to provide long-term uniform pipe
support are unacceptable. All unsuitable foundation materials should be excavated before the new
culvert pipe installation proceeds. The contractor should remove rock or unyielding material 1-
foot below grade and 6 inches on either side of pipe. Soft areas within the foundation should be
removed approximately 2 feet below grade and three times pipe width. A synthetic fabric (geotextile)
will be required to separate unsuitable native soil from backfill material.
Installation of the new 87-inch x 63-inch pipe arch will occur at the existing culvert location within the

intermittent stream using the lines and grades of the existing culvert unless final cover depth
requirements or site conditions dictate adjustments be made. The new 30-inch CMP pipe will be
located near the pipe arch with the final location determined by the Public Works Director.
The minimum trench cover depth and width requirements for the new culvert pipes will be as follows:
1. The 87-inch x 63-inch pipe arch will require a minimum of 18-inches of cover.
2. The 30-inch CMP will require a minimum of 12-inches of cover.
Trenching work will be required to follow OSHA requirements per 29 CFR 1926.651 and 1926.652 or
comparable OSHA-approved state plan requirements. Several key points included but not limited to:
• If a trench box is used, it must extend 18 inches above the surface to prevent cave-ins. The
maximum distance between the bottom of the trench box and the bottom of the trench should
be no more than 2 feet. Excavations 24 inches below the bottom of the trench box are
prohibited.
• Means of egress is required every 25 feet for all trenches.
• Trenches 5 feet deep or greater require a protective system unless the excavation is made
entirely in stable rock.
A minimum of 4 inches of bedding material will be used prior to placing the new culvert pipe. The
pipe bedding material will either a fine graded crushed gravel meeting the requirements VTrans
704.05B or sand borrow meeting the requirements of VTrans 703.03A.
An initial backfill material will be used to backfill around the pipe. This initial backfill material will be a
fine graded crushed gravel meeting the requirements of VTrans 704.05B. The backfill material will
be carefully haunched around the pipe to eliminate voids. The initial backfill material will be
compacted with appropriate compaction equipment to a minimum 6 inches above the pipe.
The remaining final cover to the surface can be suitable material removed from the original
excavation that is free of organics, refuse, muck, wet, and clayey soils. The minimum depth of cover
should meet the requirements as detailed above. The loading should meet the requirements of
AASHTO H-25.
The culvert inlets and outlets should be armored to prevent erosion and channelization. Armoring
should be made with erosion stone meeting the requirements of VTrans 706.04 (size will be based
on site conditions). The extent of the armoring will depend on the topography and specific onsite
conditions, but in general placed around the entire pipe ends and extend from the pipe inlet and
outlet ends to an extent no less than 12 linear feet (on either side of the inlet channel) and on the
downstream side of the culvert. Steep outfall topography may dictate additional armoring and
should be anticipated.
New metal culvert pipe markers (with reflectors) will be required to be installed on either side
of the new pipe. These markers should be approved by the DPW Director. The location of the new
culvert pipe should be documented, and coordinates provided to the DPW.
The road can be closed for excavation and installation of the new culvert but will require
advanced notification of at least 5 days to the Public Works Director to allow public
notification. Closure signs will need to be posted in both directions at least 5 days in
advance of work. Traffic control will be required as necessary and all traffic control delineation,
traffic signs, and flagging will be required to follow the MUTCD latest edition.
