SINGLE SOURCE DETERMINATION (Including Brand Name)

1. CONTRACTING AGENCY: U.S. Army Corps of Engineers (USACE), Walla Walla District (CENWW-CT), 201 North 3rd, Walla Walla, WA 99362.

2. DESCRIPTION OF ACTION: This action is for the purchase of qty four (4) new sheave bearings, SKF p/n 23088KYMBW507C08C3. The sheave bearings will be used to replace in kind the existing sheave bearings for the downstream navigation gate at Lower Monumental Dam for Lower Monumental Dam.

3. DESCRIPTION OF SUPPLIES/SERVICE: The sheave bearings on the downstream gate at Lower Monumental Dam will be replaced during the Lower Monumental Downstream Gate Hoist Machinery Upgrade in Fiscal Year 2017. There are four (4) sheave bearings, two in the North tower and two in the South tower.

The estimated purchase price for qty 4 SKF bearings is $20,000.

4. AUTHORITY CITED: FAR 13.106-1(b) Soliciting from a single source.

5. REASON FOR AUTHORITY CITED:

a. BACKGROUND: The sheave bearings require replacement as part of the hoist upgrades as they have exceeded their service life. The bearing housings remain serviceable and do not require replacement.

b. JUSTIFICATION: The subject make and model sheave bearing is required in order to fit the geometry and anchorage features in the existing SKF bearing housings.

c. IMPACT: Not purchasing the SKF bearing will lead to the following negative impacts:

Risk associated with modifying the existing bearing housings for installation of an incompatible make and model bearing. Non-functioning sheave bearings would prevent the operation of the downstream gate hoists and would render the navigation lock out of service.

Increased initial costs and schedule duration for the fabrication and installation of new bearing housings.

Increased initial costs and schedule duration for mounting adjustments required for a new bearing housing required by a different make and model bearing.

d. ALTERNATIVES:

i. None.

6. EFFORTS TO OBTAIN AND INCREASE COMPETITION: It is anticipated that multiple suppliers of SKF Brand bearings are present.

7. FAIR AND REASONABLE COST DETERMINATION: Based on catalog pricing an anticipated cost of $20,000 for the four (4) bearings is fair and reasonable.

8. MARKET RESEARCH: The SKF bearings are essential in order to maintain existing equipment in reliable condition. Other company’s products do not meet, or cannot be modified to meet, agency needs.

9. DETERMINATION: I certify that this J&A is accurate and complete to the best of my knowledge and belief.
