What AG Construction does
AG Construction is a family-run concrete and masonry subcontractor headquartered in Ontario, California, operating since 1988 under California Contractor's License #793245. The firm serves General Contractors across Southern California through six integrated service lines — building foundations, site concrete, decorative concrete, vertical concrete, site masonry, and structural masonry — and employs 150 field workers on direct payroll, including in-house finishing and masonry crews, eliminating dependency on outside labor. Project scope spans from approximately $350,000 specialty builds to $9 million multi-year programs, with a stated 90% repeat client rate and MBE (Minority Business Enterprise) certification.
Revenue is generated entirely through competitive project bidding for General Contractor clients, with no disclosed technology platform, software offering, or recurring managed-service component. The go-to-market is relationship-based: an in-house estimating team responds to bid invitations the same day, and 90% of work comes from repeat GCs. Notable engagements include the $9 million, seven-year Kast Cluster Residential Restoration for AECOM and Shell (2017–2023), the $4 million Wild Rivers Waterpark for KPRS (2021–2022), the $1.4 million, 40,000+ SF Loma Vista Mobility EV Charging Lot for Smith & Severson, and ongoing multi-site Starbucks rollouts via CGC, KDC, and PR Construction. The firm has selectively extended beyond core Southern California into Santa Clara and San Joaquin counties to serve clean-energy and hydrogen facility work, indicating measured geographic and end-market expansion.
The business is privately held and family-controlled, with Alberto Garcia as President, Nick Vicente as Director of Operations, and Michael Vicente as Project Manager, supported by senior superintendents, estimators, and a Safety Coordinator. No external investors, parent companies, funding rounds, or M&A activity are disclosed. Operations rely on traditional project management practices — in-house shop drawings, change order management, and daily GC coordination — and the company carries MBE certification plus a full suite of California contractor licenses (B, C8, C10, C29, HIC).

AG Construction competitors and assessment
Company assessmentBroad incumbents
- Swinerton Builders: Large California-headquartered general contractor performing commercial, healthcare, education, and multi-family construction. Not a peer in the trades sense, but a key customer profile — represents the type of GC that AG Construction subcontracts to and could grow wallet share with.
Direct peers
- Largo Concrete: Southern California-based concrete subcontractor serving commercial, institutional, and infrastructure projects. Most directly comparable to AG Construction in geography, scope (foundations, structural concrete, site work), and GC-driven project delivery.
- Conco Companies: One of the largest concrete subcontractors on the West Coast, performing foundations, structural concrete, and specialty concrete work across California and the Western US. Directly comparable business model — specialty concrete sub serving GCs — though at substantially larger scale.
- Midwest Masonry: Long-established masonry subcontractor performing structural and site masonry for commercial GC clients, including regional expansion. Comparable to AG Construction on the masonry portion of its service mix and GC-led project delivery model.
- TAS Commercial Concrete Construction: Concrete subcontractor performing foundations, slabs, and structural concrete for commercial GC clients across the Western US. Overlaps with AG Construction on poured concrete foundation and structure scope for commercial and institutional projects.
- Citation Building Group: California-based concrete and masonry subcontractor delivering foundations, site concrete, and masonry scopes for GC clients. Closely comparable trade mix and GC-driven delivery model to AG Construction.
- T.B. Penick & Sons: California-headquartered specialty contractor combining concrete and masonry services for commercial and institutional clients. Directly overlaps with AG Construction's integrated concrete-and-masonry service offering and GC-driven commercial project base.
Others
- Foundation Building Materials: National distributor and supplier of masonry, concrete, and building envelope products to commercial contractors. Adjacent rather than competitive — represents both a potential supply-chain partner and a comparable touchpoint for end-customer relationships in the masonry trade.
