QUESTION AND ANSWER

I have a question on the Orwell dam bypass project. Plans state that the bypass pumps should be installed so that they sit flat on the bottom of the concrete structure of the dam. Do we know what kind of debris, silt, or muck is at the bottom? We are concerned with these large pumps sitting flush with to bottom of the structure if there is debris there. Would floating baskets holding the pumps also work?

o Answer: It is not certain whether there is debris, silt, or muck present at the bottom. Based on the higher flow rates, I believe the likelihood is low in the upper section. However, there may be some accumulation near the step-down area (see Q & A Attachment for drawing). I do not see any concerns with using floating baskets for the pumps. Please note that the pool elevation is expected to rise during the bypass.

Are there any permits that is required of the contractor to obtain? Thinking about stormwater permits, I’m not even sure if that would apply since we aren’t doing any actual work or ground disturbing activity.

o Answer: No environmental permits are required.

We would like to know if an alternate to the electric submersible pumping system described in the project posting. We would like to bid hydraulic driven submersible pumps as an alternate. Please advise if this would be acceptable and thank you.

o Answer: The use of hydraulically driven submersible pumps is acceptable.

The required response date/time has changed from 05-Jun-2025 05:00 PM to 06-Jun-2025 05:00 PM.

The following have been modified:

SCOPE OF WORK

1. Project Description The Saint Paul District of the U.S. Army Corps of Engineers (USACE) has issued this solicitation for by-pass services at Orwell Dam near Fergus Falls, MN. The USACE operates Orwell Dam for flood risk management, water supply, fish and wildlife management, water quality, and recreation. This contract is to supply necessary services and equipment to provide an operational 80 cubic feet per second (cfs) by-pass flow from pool to the tailwater around the dam control structure during its dewatering. The by-pass system will ensure a minimal flow downstream and to facilitate a successful dewatering inspection and if needed repairs to the stilling basin.

The Contractor is responsible for supplying, installing, an operational complete by-pass flow system with a minimum flow of 80cfs. The by-pass system shall include the minimum number of pumps to provide a minimum flow of 80cfs throughout the dewatering. The Contractor shall provide all pumps, generators, piping, transportation of equipment to and from the site, labor associated with the setup, and all costs related to by-pass operations, fuel and maintenance.

All work will occur at Orwell Dam near Fergus Falls, MN, and may commence after September 2, 2025, Monday to Friday, between 0800-1700, excluding Federal Holidays. The by-pass system must be operational no later than 8:00am on September 15, 2025 and run continuously until 3pm on September 19, 2025. Should the contractor run into mechanical issues flow must be restored in less than six hours. If the issue cannot be restored within a six-hour time frame the Contractor shall immediately notify the Contracting Officer. The by-pass system removal can start after September 22, 2025, between 0800-1700, and shall be completed by September 26, 2025.

2. Project Scope Statement The following are project requirements:

Provide a minimum flow capacity of 80cfs.

Generator: The Contractor must provide a generator capable of powering all pumps, either electrically or hydraulically. Power generation shall be located at the top of the dam and the location shall be coordinated with the government. The contractor will be required to fuel and maintain the system during operations.

Piping: The Contractor shall provide leak-free piping from the pumps to the downstream discharge point, capable of withstanding pumping forces. The length of piping required is approximately 350ft as shown by the orange line in Figure 1. Contractor shall verify the required pipe length during the post award site visit.

Pumps: The Contractor shall supply operational submersible pumps capable of minimal flow of 80cfs. If the contractor choses to place the pumps on the bottom of the control structure slab it will result in approximately a minimum of 15ft of water. The distance from the bottom of the control structure to the top of the dam is approximately 43ft. See Figure 1 for cross-section. Use of pumps in floating baskets is allowable.

Location: Staging and setup shall be on the north side of the dam. The exact placement of pumps, generator, and piping shall be coordinated with the Government to avoid hindering dewatering operations, bulkhead installation, and surrounding dam instrumentation. Reference to Government-provided drawings should be made and Figure 2 which outlines the by-pass layout during the 2003 dewatering.

3. The Base of Scope of Work The Contractor shall set up the by-pass system around the concrete control structure. The upstream pool is accessible from the top of the embankment dam (elevation: 1080) on the north side and pumps can be placed on the upstream concrete control structure slab (elevation: 1037).

The Contractor shall install the pumps, generator, and piping for a minimum constant flow of 80cfs. The Contractor shall provide a suitable crane and all necessary equipment for setting up pumping operations, including piping lines. The Contractor shall utilize a generator as a power source since availability at the site is not guaranteed.

The Government will coordinate with the Contractor regarding pump and piping locations to ensure correct placement without obstructing bulkhead installation and not impact instrumentation that is located.

4. Environmental Protection:

Environmental protection is the prevention/control of pollution and habitat disruption that may occur to the environment during construction. The control of environmental pollution and damage requires consideration of land, water, and air; biological and cultural resources; and includes management of visual aesthetics; noise; solid, chemical, gaseous, and liquid waste;

radiant energy and radioactive material as well as other pollutants.

5. Submittals:

Listed below are the required submittals. All submittals are required to be approved by Contracting Officer prior to any work or mobilization to the site.

(1) By-Pass Plan: The layout of the by-pass system shall be submitted and include the following:

a. Number and type of pumps to be used. Specifying capacity and operations details.

b. Type of piping material with diameter specifications and details on joints (e.g.

connection procedures).

c. The generator specifications for on-site power supply.

d. Details of the crane and other equipment necessary for installation to ensure compliance with the site.

(2) Schedule: The contractor shall submit a detailed schedule for review and the schedule must include:
