Montano Pipeline, Inc. in Chula Vista holds CSLB #829293 with Class A general engineering and C-34 pipeline classifications, executing heavy civil construction from its Fourth Avenue headquarters since 2010. Sewer main installations and lateral tie-ins on Montano projects connect new infrastructure to existing municipal collection systems maintained by drain-service contractors including Speedi Rooter Sewer & Drain on the post-construction side. The scope covers earthwork, excavation, demolition, pipeline construction for water, sewer, storm drain, fire lines, and bioswales, plus concrete flatwork, CMU walls, chain-link fencing, and asphalt paving. As a member of AGC San Diego and the Chula Vista Chamber of Commerce, Montano coordinates dry-utility trenching for electrical and communications conduit with Arcelectric, Inc to maintain separation distances required by SDG&E utility standards. The firm's highest-complexity deliverable is a full traffic-control and street-cut restoration package for municipal right-of-way pipeline replacements requiring T-17 trench backfill compaction to 95-percent relative density per City of Chula Vista Standard Drawing S-4.
