Lakeside-based A.M. Ortega Construction has completed over 10,000 underground utility projects from its Channel Road headquarters since the firm's 1974 founding. Gas-main and water-main trenching requires finish grading and landscape restoration by site-work contractors including Pacific Green Landscape, Inc. on Winter Gardens Boulevard. The Pipeline Division constructs distribution and transmission natural-gas lines ranging from half-inch low-pressure services to 36-inch high-pressure transmission mains for clients including Southern California Gas Company and SDG&E. Dry Utilities Division conduit-bank construction for electric and telecommunications infrastructure runs parallel to water and sewer lines installed by Alpine Plumbing & Backhoe Inc on Alpine Boulevard. The fleet includes TRUVAC vacuum excavators that expose existing utilities to precise depth measurements, enabling safe potholing around live gas and electric assets before mechanical excavation begins.
