About the company
Meca Consulting Inc., doing business as Millennium Consulting Associates, is a self-certified small disadvantaged business providing environmental, health, and safety consulting services to federal agencies as a prime contractor on the GSA Multiple Award Schedule and agency-specific blanket purchase agreements. The firm operates as a Subchapter S corporation headquartered in Pleasanton, California, and competes full-and-open across a diversified federal customer base rather than relying on set-aside vehicles—recent awards split evenly between set-aside and non-set-aside designations.
Meca Consulting's capability portfolio centers on industrial hygiene surveillance, asbestos and lead inspection and assessment, air quality monitoring, legionella water testing, hazardous material surveying and remediation oversight, and facility environmental compliance work. Representative prime work includes a $4.387 million firm fixed-price delivery order from GSA's Public Buildings Service for development of an ASHRAE 188 water management plan at a federal facility (awarded October 2026), a $528,860 industrial hygiene site survey delivery order from the California National Guard (September 2023), a $350,765 asbestos inspection services contract from the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 22 running through June 2027 (awarded June 2023), and a $956,582 industrial hygiene site surveys delivery order from the California National Guard (September 2022). A long-standing multi-year BPA with GSA Public Buildings Service Region 9 valued at $950,000 anchors recurring work providing air monitoring and industrial hygiene surveillance at federal buildings in the Los Angeles and Orange County area.
Customer concentration is acute but segmented by transaction volume and dollar value. The top five customer agencies account for 69% of award count, led by the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 22 (31 awards, $12 million combined potential value) and GSA Public Buildings Service Region 9 (23 awards, $2.5 million combined potential value). The dollar rankings surface a different lead customer: GSA's Federal Acquisition Service holds a single award valued at $13.7 million, the October 2026 ASHRAE water management plan delivery order, which dominates the potential-value portfolio at roughly 35% of the vendor's combined potential value across all awards.
Meca Consulting places 99% of its volume through the GSA Multiple Award Schedule, with 57 task orders and $20.8 million combined potential value, supplemented by The Professional Services Schedule (9 task orders, $4.3 million) and agency-specific BPAs including the recurring Chet Holifield Federal Building surveillance BPA. The vendor has one documented subcontract sub-award, a June 2024 task under Aptim Federal Services for Department of Energy Lawrence Livermore National Laboratory Building 251 deactivation, decommissioning, and removal work. Activity across the past five years has been steady with slight growth in 2024 (nine awards) after a flat 2022–2023 period. Only two awards (combined potential value $4.7 million) face ultimate completion within the next twenty-four months, indicating light recompete pressure in that window. Primary NAICS concentration is 541620 (Environmental Consulting Services), which accounts for 84 of the vendor's 98 awards in source data spanning from 2003 to October 2026.
