This is a Sources Sought Announcement for Medicine Creek Dam Concrete Repair of damaged spillway concrete and Access Improvements. The purpose of this notice is to gain knowledge regarding the types of interested contractors and their qualifications. The Bureau of Reclamation will use information obtained through this notice to develop an acquisition strategy. Proposals are not requested and will not be accepted from this Sources Sought Notice. THIS IS NOT A SOLICITATION

FOR PROPOSALS AND A CONTRACT WILL NOT BE AWARDED AS A RESULT OF THIS NOTICE.

Work is located at Medicine Creek Dam, which is approximately 11 miles north of Cambridge, Nebraska in Frontier County and forms Harry Strunk Lake. This earthfill embankment dam has a structural height of 165 feet and an uncontrolled spillway on the left abutment which empties back into Medicine Creek. The outlet works through the dam is controlled by a high-pressure gate and releases flow into an armored channel downstream.

The principal components of work that would be completed under this project include the following:

A. Provide construction management, including submittal preparation, transmittal, comment incorporation, and resubmittal process;

B. Construct a site access road, including culverts at the outlet works discharge channel crossing;

C. Saw cut and remove existing concrete from damaged areas within the spillway chute and along the outlet works stilling basin walls;

D. Furnish and place new concrete in repair areas, and raise the outlet works walls by 2 feet;

E. Repair cracked concrete on the spillway bridge piers;

F. Project closeout and lessons learned.

See attached drawings and pictures for more information.

The Government is seeking potentially interested contractors who have the specialized knowledge, experience and resources required to successfully complete a project of this size, scope and complexity particularly as it relates to specialized dam concrete spillway repairs. The NAICS Code for this project is 237990 – Other Heavy and Civil Engineering Construction with a business size standard of $45 million.

NOTES

1. For general concrete outline notes, refer to Drawing No. 328-600-60064.

2. Preserve existing reinforcement per Specifications.

3. Depth of existing reinforcement (where present) is assumed to be 3 inches. Saw cut and drill cores around repair perimeters to a maximum depth of 2 inches.

4. Where existing reinforcement is exposed by concrete removal, adjust location of repair edge as necessary to provide a minimum clear distance of 1.5 times the new concrete's maximum aggregate size behind existing reinforcement.

5. Remove spillway floor concrete to a depth of (a) 8 inches from the existing surface, OR (b) 1.5 times the maximum aggregate size of new concrete below existing reinforcement (where present), OR (c) to sound concrete as determined by COR, whichever is greater.

6. Clean and dry existing concrete to saturated surface dry condition prior to installing replacement concrete.

7. Finish new concrete to provide a smooth, even surface and a flush interface with the existing concrete. Unless otherwise noted, match original lines and grades.

8. When placing new concrete immediately downstream of transverse joints, bevel finish from original grade at 6 inches downstream of the joint to a depth of 1/2 inches below original grade at the joint.

NOTES

1. Prior to construction and wherever possible, remove existing features that may impede concrete removal and placement, and re-install them afterwards at original locations.

2. Remove all damaged concrete.

3. Match existing batter (5/8" per foot) on outer faces.

4. Remove exposed portions of existing rubber waterstop or

6" metal sealing strip and install PVC waterstop to 6" below new top of wall.

5. Remove and replace existing 3/4" preformed joint filler, extending it to new top of wall.

6. For general concrete outline and reinforcement notes, see Standard Drawings 40-D-60003 and 40-D-60004.

NOTES

1. Horizontal locations are based on the North American Datum of 1983 (NAD 83) Nebraska State Plane coordinate system. Topography is referenced from a local datum on the dam embankment, which is based on the North American Vertical Datum of 1988 (NAVD 88).

2. Northings, eastings, and distances provided for alignments are given in U.S. feet, and bearings are based on NAD 83 Nebraska State Plane coordinates.

3. Replace topsoil over disturbed areas not covered by gravel surfacing, and reseed.

Figure 7. View of the spillway notch, facing upstream. Note that water seeps from the transverse joint at the base of the crest structure. Water stains along the side of the notch are a result of leakage past the flash boards on its crest, which will not be an issue during construction.
