What Blocka Construction does

Blocka Construction Inc. (BCI) is a privately held, employee-owned (ESOP) industrial general contractor founded in 1991 and headquartered in Pleasanton, California. The firm operates three integrated service divisions — Electrical Services (power distribution, control systems with PLC/SCADA integration, lighting, preventative maintenance), Mechanical/Sheet Metal Services (HVAC, equipment installation, ventilation, precision alignment), and General Engineering Services (civil, structural, utility infrastructure, foundations, paving) — supported by a dedicated Estimating department that prepares competitive bid packages. BCI holds California Class A General Engineering, Class B General Building, C-10 Electrical, and C-20 HVAC contractor licenses (CSLB License 679326, CA DIR Registration 1000000447), enabling single-source delivery of multi-disciplinary industrial scopes.

BCI serves exclusively government, municipal, and institutional clients across Northern California. The named customer base spans water/wastewater agencies (Sacramento County Water Agency, Ukiah Valley Sanitation District, Freeport Regional Water Authority, Zone 7 Water Agency, SFPUC, Alameda County Water District, EBMUD, LGVSD, SCVWD), transit authorities (SFMTA, BART), municipalities (City of San Jose), and educational institutions (UC Berkeley, San Jose State University). Project values range from $1.3M to $35M, with documented scope of work exceeding 60,000 manhours on individual jobs (Ukiah WWTP) and 80 light rail vehicle storage capacity on the SFMTA MME LRV Maintenance Facility, the latter recognized as the 2009 APWA Public Works Project of the Year.

BCI generates revenue through fixed-price construction contracts awarded via competitive public bidding, typically structured as multi-year engagements. The go-to-market motion is sales-led and relationship-driven, with no intermediaries, resellers, or distribution channels; business development relies on direct engagement with public agencies, the company's past-performance portfolio, and repeat qualifications on capital programs. Revenue is not publicly disclosed, and ownership is closely held with an ESOP and 401(k) non-discretionary employer contribution in place to retain skilled craft labor. Geographic operations are concentrated in Northern California (San Francisco Bay Area, Sacramento, Ukiah) with no documented expansion outside that region.
