4. Existing culvert 29 will be replaced with an 18-inch ADS HP Storm Dual Wall Gray Pipe that
will be approximately 50 feet in length. Final lengths shall be verified by the contractor.
5. Existing culvert 30 will be replaced with an 18-inch ADS HP Storm Dual Wall Gray Pipe that
will be approximately 50 feet in length. Final lengths shall be verified by the contractor.
In each location as detailed above, the existing culverts will be excavated, removed, and disposed of
by the contractor.
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.
Excavation will occur at each culvert location using the lines and grades of the existing culverts unless
final cover depth requirements or site conditions dictate adjustments be made. Minimum trench
cover depth and width requirements for the new culvert pipes will be as shown on the Trench
Installation Detail in Attachment No.1.
Trenching work (if required) will be required to follow OSHA requirements per 29 CFR 1926.651 and
1926.652 or comparable OSHA-approved state plan requirements.
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.
All culverts described above will be replaced with ADS HP Storm Dual Wall Gray Pipe or
approved equivalent. Refer to the ADS Corrugated Plastic Pipe Storm Installation Guide for
installation details.
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 can be suitable material removed from the original excavation that is free of
organics, refuse, muck, wet, and clayey soils. Soils should be placed in layers that are no thicker
than 6-8 inches and compacted (utilizing water if necessary). The top final 4-inches should be a ¾-
inch gravel hardpack material (as approved by the Owner).
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 a
minimum of 7 inches or greater as approved by the Owner). The extent of the armoring will depend
on the topography and specific onsite conditions, but in general placed around the entire pipe ends
extending 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.
In areas where roadside shoulders are present, the shoulders should be re-installed as similar to
Request for Bids – Turnpike Rd Culvert Replacement 22, 24, 25, 29, 30 and Stormwater Ditching
Page 3
adjacent areas in depth and type of gravel.
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.
Stormwater ditching should be completed in the following locations:
1. Culvert 22 should be ditched on the upstream side approximately 25 linear feet north.
2. Culvert 24 should be ditched on the west side north of the culvert approximately 50 linear feet.
3. Culvert 25 should be ditched 25 linear feet on the south end and 125 linear feet on the north end
4. Culvert 30 should be ditched on the east side approximately 140 linear feet.
Stormwater ditches between 0% and 5% are to be grass-lined. For ditches between 5% and 8%,
the ditches should be grass-lined with stone check dams. Check dams cannot be greater in height
than 2 feet, center of dam lower than ends, 2:1 side slope, mixture of 2-inch to 9-inch stones and
spanning the width of the channel. For ditches greater than 8% the ditches should be stone lined
with 6-inch to 8-inch minus. Any excess ditch spoils should be removed offsite and included in the
bid price.
The road can be closed for excavation and installation of the new culverts but will require
advanced notification of at least 5 days from 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.
All construction work will be performed in accordance with the technical requirements of the Vermont
Agency of Transportation 2024 Standard Specifications for Construction. Payment for the work shall
be based on the pay units and unit prices defined in the bid tabulation and the Request for Bids.
