About Kjeldsen, Sinnock & Neudeck, Inc.
Kjeldsen, Sinnock & Neudeck, Inc. is a for-profit corporation based in Stockton, California, that performs water well service and repairs and civil engineering surveying for federal agencies as both a prime contractor and subcontractor, operating under Total Small Business set-asides.
The company's recent federal footprint spans three awards across two distinct customer agencies, with combined potential value of $898 thousand. The prime award is a $897.9 thousand Total Small Business purchase order from Air Combat Command for water well service and repairs at Beale Air Force Base, California, with a ceiling of $897,910.50 and ultimate completion on March 31, 2027, issued April 1, 2026 under firm fixed pricing. Kjeldsen subcontracts on civil engineering and surveying work under the prime contractor Kleinfelder-Stantec USACE Joint Venture: a November 2024 sub-award for topographic survey services on the Sacramento River East Levee Contract 5 in Sacramento, California, and an August 2023 sub-award for surveying and quality assurance laboratory testing on the American River Common Features project in Natomas Basin Reach E, Sutter County, California, both under the Dam and Levee Safety Program Design Services vehicle.
The Department of the Army Corps of Engineers accounts for two awards by count; the Department of the Air Force Air Combat Command anchors the dollar value with the single $898 thousand potential-value prime award. The vendor places subcontract work through the Dam and Levee Safety Program Design Services vehicle, which carries two task orders. The primary subcontract relationship runs to Kleinfelder-Stantec USACE Joint Venture on water resources and civil infrastructure projects. Activity is sparse and sporadic — one award per year across 2023, 2024, and 2026 — with the Beale AFB contract facing recompete in the next twenty-four months. The combined obligated dollars ($1.1 million) exceed the combined potential value, indicating some task orders have been executed beyond initial ceiling.
