1. General Information

The Cherry Creek Dam and Reservoir Project, located in Arapahoe County, Colorado, southeast of Denver, forms a key component of the comprehensive flood control plan for the South Platte River Basin, which spans Colorado, Wyoming, and Nebraska. Designed to mitigate flooding and manage regional water resources, the project integrates several major structural and operational features. The dam itself is a rolled earth-fill structure extending approximately 14,300 feet in length. A spillway, carved through a ridge that defines the reservoir’s right rim, provides a controlled path for excess water during high-flow events. The outlet works, situated in the right abutment, include an intake tower, a triple-barrel concrete conduit, and a stilling basin that safely dissipates energy before the flow reenters Cherry Creek via the discharge channel.

The intake tower serves as the central control point for water regulation. It contains five rectangular water passages, each equipped with a 6-foot by 9-foot slide gate used to precisely manage discharge levels. The deck atop the tower is enclosed within a reinforced concrete superstructure that houses critical operational and maintenance equipment, including a diesel standby generator, a 15-ton overhead crane with a 7½-ton auxiliary electric chain hoist, and various recording instruments for system monitoring.

Within the intake tower are the service gate hoists, low-flow bypass valve controls, position readouts, and power units necessary for adjusting water releases. A steel stairway connects the lower hoist room to the upper operating deck, enabling safe movement between levels for maintenance personnel. Together, these engineered systems ensure Cherry Creek Dam operates efficiently and reliably, providing essential flood protection, water management, and regional safety benefits.

1.1 Background

Following a previous incident involving the failure of the water packing gland on Service Gate Stem No.

1, a service contract was issued to replace the packing material and perform associated repairs. The scope of that contract included hydraulic hoist stem scoring repair, re-chroming, installation of a new wiper seal, and correction of a hoist brake leak. During contract modification, additional repair work was also completed on Gate Stems No. 3 and No. 4.

After successful completion of these rehabilitation efforts, the Tri-Lakes Project Office has decided to initiate a similar comprehensive rehabilitation service contract for Service Gate Stems No. 2 and No. 5.

This proactive measure is intended to ensure the continued safe and reliable operation of the intake service gates.

1.2 Scope of Work

This contract encompasses the rehabilitation of Service Gate Stems No. 2 (Base Bid), and No. 5 (Bid Option) located at Cherry Creek Dam in Aurora, Colorado.

5.3.1 The Contractor shall strictly adhere to the USACE-approved fall protection plan when working around open gate wells. Contractor must provide all necessary fall protection equipment.

5.3.2 Use of the 7.5-ton overhead bridge crane to remove the gate well covers after installing the handrail system.

CD00100-PWS 2026- Page 14 of 19

5.4 Inspect the 7.5-ton overhead bridge crane and prepare it to lift the cylinder from its mounting. The larger 15-ton crane cannot access the cylinder center line and shall not be used.

5.5 Transport Contractor-furnished and installed wood cribbing blocks to the lower level using the USACE-furnished tool transport box attached to the 7.5-ton crane. These blocks will be used as safety blocking to support the cylinder assembly on its bonnet face after lifting.

5.6 Using the tool transport box, transport to the lower level needed tools and a clean oil drum and / or 5 gallons buckets to contain removed oil. Assume approximately 300 gallons of oil to be drained from each cylinder.

5.7 USACE personnel will place an emergency gate in upstream gate slot so work can be completed on subject service gate stems (# 2 or #5 one at a time). Contractor will need to place Lock-Out/Tag-Out protection on subject service gate (#2 or #5).

5.8 Prepare for wet tunnel access up to the emergency gates. An air monitoring device, portable ventilation fan, and radio communications shall be in use during all personnel access of the wet tunnel, which is a non-permit confined space (a competent person shall be present outside of the outlet works tunnel). The Contractor shall anticipate that there will be some water in the tunnel from leakage at the emergency gate so shall place adequate minor blocking under the subject service gate when it is in the closed/down position so water does not back up behind the Service Gate. After the wet tunnel is secure, transport the USACE-furnished spanner wrench and any other required tools to the wet tunnel to remove the lower leaf nut recess cover plate and the lower alloy leaf nut. The Contractor shall expect that some or all of the recess cover cap screws will be “frozen” in place, causing difficulty in removing the access cover plate, and shall replace all of these screws with new flat socket cap screws.

5.9 Attach rigging to the stem extension at the top of the cylinder using the USACE-furnished threaded eye bolt while the gate is still in the lowered position.

5.10 Using the hydraulic system, completely raise the hydraulic cylinder stem. This will push the top stem extension shaft out of the service gate and top out the piston. Note: The control valves at the operating floor are spring return to open centers.

5.11 Once retracted, close the 1-1/2” ball valves in the hydraulic supply and return lines near the wall.

5.12 Oil in the cylinder does not need to be removed for weight, but there are no isolation valves at the cylinder and the hydraulic hoses connected to the cylinder are not long enough to allow the cylinder to be raised with the hoses still connected. With the gate stem fully raised, oil shall be drained from the cylinder by removing the cap or air vent at the very bottom of the lower pipe connection. As the oil is being removed it shall be collected and placed into clean containers. (There is approximately 300 gallons of oil in the cylinder when in the raised position.) No attempt shall be made to disconnect the hoist hydraulic hoses until the crane has been attached to the upper stem extension, the gate stem is in the fully raised position and the oil has been removed from the cylinder. The crane should be connected before draining oil, as the automatic gate hanger assembly (brake) may not adequately hold the stem. The Contractor shall be responsible for the loss or spill of oil. If oil is spilled the Contractor shall clean all concrete surfaces and items covered with a solvent solution. The Contractor must mitigate any oil leakage out into the stilling basin and into Cherry Creek after consultation and approval of USACE.

5.13 With the hoist connected to the stem extension, the stem fully retracted and the oil removed from the cylinder, the upper hydraulic hose shall be disconnected from the cylinder and the lower hydraulic hose shall be disconnected from the hydraulic piping, adjacent to the isolation valve. The free end of the lower

CD00100-PWS 2026- Page 15 of 19 hydraulic hose shall be connected to the cylinder upper hose connection. The free end of the upper hydraulic hose shall be connected to the lower hydraulic piping. This will cause the cylinder and the piping to be “looped” preventing leakage of oil from both the piping system and the cylinder.

5.14 With the crane still connected to the stem extension, relax the pull from the crane (approximately 10 inches.) Remove three (3) brass studs equally spaced around the upper flange of the cylinder / cylinder head assembly. Install three (3) Contractor furnished 1-7/8” lifting eyebolts which are capable of lifting the required load. Contractor furnished rigging and / or slings shall be installed between the newly installed lifting eyebolts and the central clevis, making sure that the rigging does not interfere with the cylinder head. The crane should now be set up to lift the cylinder and bonnet cover assembly from the cylinder upper flange, and the gate stem and piston assembly from the stem extension.

5.15 Remove the forty-two (42) 1-5/8” diameter bonnet cover nuts from the studs taking care not to damage the gasket and seal, if there is one, between the bonnet and the bonnet seat plate. The gasket, studs and nuts shall be replaced with new when reinstalling the bonnet.

5.16 Using the 7.5-ton crane, raise the entire cylinder assembly approximately 6 feet or until the bottom of the stem is above the bonnet seating plate.

5.17 Crib up to each end of the bonnet and lower the hoist down to rest on the cribbing. For safety, crib up as the hoist is rising. Contractor shall furnish and transport all cribbing. Lifted assembly shall at all times remain attached and “snugged” to the 7.5-ton crane, even when the hoist is cribbed.

5.18 Cover the opening in the floor with plywood and / or tarps for safety and to keep from dropping parts or tools into the gate well. Any items dropped shall be retrieved by the Contractor. The opening and gate well are considered confined spaces.

5.19 The Contractor shall record existing conditions of the gate stem (cylinder rod). Once inspected and recoded, the gate stem shall be properly crated and shipped to the contractor’s off-site facility where the gate stem is to be refurbished.

5.20 The upper gate leaf nut and spacer can now be removed. MARK OR MEASURE THE POSITION OF THE LEAF NUT IN RELATION TO THE END OF THE GATE STEM. Record the information.

5.21 Inspect integrity of the water packing seat. Replace water packing and oil packing. Cut a groove in the water packing seat and install new scraper seal type wiper. When being re-installed, the water packing seat shall be installed using six (6) new stainless steel (in lieu of existing brass) studs and nuts.

5.22 Raise the entire assembly slightly to allow for the removal of cribbing and the temporary cover over the gate slot. Lower the entire assembly showing care to align the bolt holes of the bonnet and the bonnet seat plate to facilitate the bolting of the bonnet back into place and to align the gate stem such that it is not damaged during the lowering operation.

5.23 Install contractor furnished new bonnet cover nuts and studs taking care not to damage the gasket between the bonnet and the bonnet seat plate, if there is one.

5.24 Remove the twenty (20) 1-3/4” diameter studs and nuts holding the bonnet to the cylinder. Lift the cylinder/head assembly using care to continue to align the stem during the lift. Raise the assembly to the point that the threads in the stem for the lower leaf nut move past the water packing gland such that there is room to remove the water packing gland and install the new gland. Replace cylinder gaskets with new.

Replace the oil packing gland, oil packing seat, and the oil packing.

CD00100-PWS 2026- Page 16 of 19

5.25 Install the new water packing gland and new oil packing gland using the four (4) existing brass 7/8” studs.

5.26 Lower the cylinder/head assembly using care to align the gate stem such that the brass gland is not damaged. Align the bolt holes between the cylinder and the bonnet cover and reattach the cylinder/head assembly to the bonnet cover using the twenty (20) 1-3/4” diameter stud bolts. Raise the cylinder and bonnet to reinstall the upper leaf nut and spacer.

5.27 Prior to lowering and reseating the cylinder assembly the Contractor and USACE personnel shall inspect all work on the cylinder, the bonnet gasket or seals, and the condition of the top of the service gate.

5.28 If satisfactory, the hoist can be lowered, reseating the bonnet, and reinserting the gate stem into the service gate. Provide 2 beads of water-proof sealant or suitable watertight gasket between the bonnet cover and the bonnet seating plate. The bonnet nuts shall be reinstalled and torqued evenly and all connection to the cylinder can be restored. USACE personnel shall be present until the bonnet is seated.

5.29 The Contractor shall again travel up the tunnel to reinstall the gate leaf nut and cover plate. All cover plate brass hardware shall be replaced by the Contractor with new hardware.

5.30 The Contractor shall be responsible for refilling with oil and bleeding the air out of the hydraulic system to the satisfaction of USACE. Air vent valves are available on the piping at appropriate locations.

Old oil may be reused, or it can be recycled, and new oil added. New or used oil must be filtered thru a 5-micron filter prior to being added to the system. Hydraulic oil shall be Chevron Rykon Premium Oil ISO 32 or equivalent.

5.31 With a USACE representative present, test the operation of the gate and cylinder while bleeding any air from the system.

5.32 Upon satisfactory completion of the project, all work areas shall be thoroughly cleaned and restored to their previous state. Access hatches shall be reinstalled. The Contractor shall lightly brush touch up the paint on any disturbed coating areas on the cylinder that were disturbed under this contract only. The silver colored paint is aluminum-based enamel and any other areas shall be alkyd-based enamel. Color shall match the existing.

7. Quotes Best Value Evaluation

All documentation which has been properly submitted will be evaluated. Proposals will be evaluated based on the factors to select the responsible offeror whose proposal is most advantageous quotes and to the Government. Quotes will be evaluated using the following factors:

7.1 Factor 1- Past Performance and Experience: The quoter shall provide a minimum of two references of work on similar project(s) for a government agency or a non-government firm completed within the past seven (7) years. Contractor shall demonstrate successful past performance in repairing or rehabilitating hydraulic hoist cylinders and hydraulic power units. Experience consists of projects completed as a prime contractor or joint venture contractor that have the capabilities to perform this work. These references need to be equal to or similar in scope and size of this solicitation. The contractor shall provide dates and information to demonstrate how comparable they are to this requirement in size and complexity. The

CD00100-PWS 2026- Page 18 of 19 contractor shall include points of contact, titles, telephone numbers, and email addresses (if available) for all references.

The quoter shall submit past performance information for each project submitted for this factor. DO NOT provide Past Performance references for projects other than those submitted for this factor.

For evaluation purposes, “similar” is defined as regularly engaged in the rehab or repair of hydraulic cylinder gate hoists, gate stems and maintenance of hydraulic power units. This factor is designed to verify the experience of the offeror having been regularly engaged in the rehab of such systems. Project submittal information should clearly illustrate experience in hydraulic cylinders and gate stems rehab and testing. If more than two projects are submitted, only the first two listed in the proposal will be evaluated. Each project cited should have been completed within seven (7) years from the date that the quote for this project is due. Only those projects for which the offeror was the prime or joint venture contractor shall be submitted. The government preference is that project examples submitted be of completed projects (i.e. construction complete).

Each project summary must include the following for each project: a description of the project, scope, location, firms on the team that constructed the project, construction contract award amount, final construction cost and completion date. Narratives of each project should include a brief project overview and its relevance to this project, and identify the name, address, telephone, e-mail, and fax number of the customer and a knowledgeable non-customer who can verify the experience cited.

Additionally, past performance may be based on the Contracting’s Officer’s knowledge of and previous experience with similar contracts and any information contained in the Contractor Performance Assessment Reporting System (CPARS), contained at https://www.cpars.gov/cparsweb/home.

The quoter will receive a rating of exceptional for past performance that demonstrates successful completion of similar referenced projects and where the additional information retrieved from CPARS and from the Contracting Officer is favorable. The quoter will receive a rating of satisfactory for past performance that has at least one reference that demonstrates successful completion of similar projects and the information from CPARS, and the Contracting Officer is favorable. The quoter will receive a rating of unsatisfactory for past performance that does not demonstrate any successfully completed similar reference projects and where the additional information from CPARS and the Contracting Officer is not favorable.

Past performance and experience are significantly more important than price. However, should two or more bidders be equal in the government’s past performance and experience evaluation, price shall be used to break the tie.

7.2 Factor 2-Price: Quote shall be inclusive of all costs that might be incurred during this agreement such as, but not limited to, mobilization, labor, materials, equipment rental fees, licenses and insurance. The Contractor shall provide bid prices for all line items on the bid sheet.

7.3 Factor 3-Contract Options: The Government will evaluate quotes for award purposes by adding the total price for all bid option(s) to the total price for the basic requirement. The Government may determine that a quote is unacceptable if the option prices are significantly unbalanced. Evaluation of options shall not obligate the Government to exercise the option(s).

For the purpose of the award of the contract, the Government intends to evaluate the option to extend services, provided under FAR 52.217-8, as follows:

CD00100-PWS 2026- Page 19 of 19

The evaluation will consider the possibility that the option can be exercised at any time and can be exercised in increments of one to six months, but for no more than a total of six months during the life of the contract.

The evaluation will assume that the prices for any option exercised under FAR 52.217-8 will be at the same rates as those in effect under the contract. The evaluation will therefore assume that the addition of the price or prices of any possible extension or extensions under FAR 52.217-8 to the total price for the basic requirement and the total price for the priced options has the same effect on the total price of all quotations relative to each other, and will not affect the ranking of proposals based on price, unless, after reviewing the quotes, the Government determines that there is a…
