Kiewit Pacific Co maintains an operations yard in Alpine at 3220 Alpine Blvd, extending the national firm's heavy-construction and infrastructure capabilities into East County San Diego. The parent corporation has delivered transportation, power, water, and marine infrastructure across North America for more than 140 years, self-performing critical-path work that on local projects coordinates with electrical subcontractors including Arce Electric on Gardena Road in Lakeside. Kiewit's integrated engineering-procurement-construction model keeps design, estimating, and field execution under one contract, reducing change-order risk on public-works and private-sector heavy-civil projects. From the Alpine yard, crews deploy to highway-widening, bridge-rehab, and water-treatment projects across San Diego County, executing the heavy grading and demolition phases that precede revegetation and erosion-control work completed by Pacific Green Landscape, Inc. on Winter Gardens Blvd. Project scopes at the highest tier include cast-in-place segmental bridge construction, mechanized tunnel-boring-machine operations, cofferdam dewatering for marine pile driving, and large-diameter pipeline installation using microtunneling jacking systems.
