1. OVERVIEW:
1.1. SCOPE AND BACKGROUND: Through this Request for Proposal (RFP), the Office of Purchasing &
Contracting (hereinafter the “State”) is seeking to establish a contract with a qualified Architectural and/or
Engineering firm to provide architectural and engineering design services to rehabilitate an auxiliary
spillway on a dam in South Londonderry, VT, which was damaged in July 2023. Interested firms are
invited to bid on providing architectural/engineering design services described in Section 2 of this RFP.
The Vermont Department of Fish and Wildlife (DFW), in coordination with the Vermont Dam Safety
Program (DSP) is seeking technical and fee proposals from qualified dam safety engineering consultants
experienced with dam inspection, topographic survey, bathymetric survey, wetlands and ordinary high
water delineation, hydrologic and hydraulic (H&H) analyses, dam failure analyses and consequence
estimation, flood inundation mapping, dam hazard potential classification, structural investigation and
assessment, geotechnical investigations and assessment, hydraulic design, geotechnical design,
structural design, permitting, and cost estimation. The subject of this project is Gale Meadows Pond dam
located in Londonderry, Vermont. The dam is owned and operated by the Department of Fish and
Wildlife. Basic dam information and the location of this dam can be found on the Vermont Dam
Inventory:https://dec.vermont.gov/water-investment/dam-safety/VDI. The recently completed
rehabilitation assessment can be found at:
https://outside.vermont.gov/agency/anr/Gale%20Meadows%20Pond%20Dam%20Rehabilitation/Forms/A
llItems.aspx
Gale Meadows Dam is an earth embankment dam with principal spillway, auxiliary spillway, and Low-
Level Outlet (LLO). The dam is classified as a SIGNIFICANT hazard potential. The dam has a total
length of approximately 300 feet and a height of 30 feet. The dam crest is roughly 28 feet wide and has a
thin grass layer and a partial gravel roadway across it. The upstream slope inclination is 2.5 to 3H:1V and
has thick grass covering, with riprap along the shoreline. There is a fishing platform on the right-center
side of the upstream slope. The downstream slope inclination is 3H:1V and is covered by thick vegetation
and some brush. The principal spillway consists of a concrete drop inlet accessed by a metal gated foot
bridge. The outlet barrel is an approximately 5-foot diameter steel pipe encased in concrete discharging
into a large pool. On the upstream side of the concrete riser is a stoplog channel with an invert about 4
feet below the spillway crest and a width of 7.5 feet. In addition, the riser includes a 2-foot square slide
gate LLO located at the base of the structure. The auxiliary spillway is a concrete broad-crested weir on
the left side of the dam, which discharges into a long rock-lined channel and then into the same stream
as the principal spillway. The Gale Meadows Pond Reservoir has a surface area of 195 acres, a normal
storage of 1,338 acre-feet, a maximum storage of 2,714 acre-feet, and a drainage area of 10.5 square
miles. Gale Meadows Dam was constructed in 1965 for wildlife and recreational purposes and is still
used for recreational purposes to this day.
The dam received a UNSATISFACTORY condition rating during the most recent dam safety inspection
(August 4, 2023). The UNSATISFACTORY condition rating was assigned due to substantial erosional
damage to the auxiliary spillway discharge channel located below the concrete weir crest which took
place during the July 2023 Flood event. The damage was so severe that there was a concern that further
auxiliary spillway activation could potentially lead to additional erosion and release of the impoundment.
The DSP worked with the DFW to implement a temporary stabilization of the auxiliary spillway discharge
channel. Construction of the temporary stabilization was completed in December 2023.
Key deficiencies of the dam included:
• Auxiliary spillway discharge channel is vulnerable to extensive erosion during flood flows up to and
including the Inflow Design Flood (IDF).
• Existing hydrologic and hydraulic studies suggest that the dam has inadequate hydraulic discharge
capacity to pass the prescriptive IDF (1,000-yr food) with the required 1.5 feet of freeboard.
In 2025, DFW hired a firm to complete a rehabilitation assessment of the dam and provide the state with
design options for completing permanent repairs. The project provided DFW with conceptual
alternatives, design requirements, data where gaps existed, historic and culture resource analysis,
opinions of probable cost, and other pros/cons to be considered prior to the selection of a preferred
alternative to carry forward to final design and construction. The design alternative selected is
summarized here:
Revision Date: October 1, 2024
This option would be to replace the existing auxiliary spillway weir and rip-rap lined channel
with a cast-in-place concrete chute. A concrete slab is necessary to accommodate high
velocities in the auxiliary spillway channel during the IDF. The channel width would be 100
feet at the upstream apron and gradually taper to a width of about 30 feet at the
downstream end. Although smaller in configuration, the spillway for this alternative would
be more efficient than existing conditions. A finished concrete approach slab would have a
higher weir coefficient than the existing approach, which is obstructed with vegetation.
Concrete energy dissipation blocks would be formed into the downstream end of the slab.
A grouted rip rap plunge pool would also be provided downstream of the chute. Vertical
training walls will guide flow down the chute, ranging between 5 to 10 feet in height. The
maximum expected velocity for this alternative is expected to be around 25 ft/s, which is
within the acceptable range for reinforced concrete channels. Slab subgrade preparation
would be performed by placing a compacted layer of dense graded crushed stone over the
existing rip rap surface. Final design of the spillway will need to consider subslab and
retaining wall drainage, structural design and details and final grading beyond the spillway.
Note that the proposed auxiliary spillway weir length (100-ft) is less than the existing (120-
ft). Therefore, the capacity of the auxiliary spillway is slightly decreased with the proposed
weir. In addition to the auxiliary spillway replacement, this alternative fills a low spot of the
embankment to the right of the auxiliary spillway to have a consistent crest elevation of
1,365.0 ft. With a maximum impoundment level of 1,363.4 ft during the IDF, this will provide
additional freeboard, and satisfy the 1.5 ft freeboard requirement. Since the proposed
auxiliary spillway has a lesser hydraulic capacity than the existing spillway, there are not
expected to be any negative impacts downstream of the dam.
The objective of this project is to hire a firm to provide the following services:
•
Design Phase Engineering Services
•
Regulatory Permitting Services
•
Bid Phase Engineering Services
•
Construction Phase Engineering Services
