What RADCO does

RADCO is a private company providing testing, listing, and assurance inspection services for building systems and materials, founded in 1967 and headquartered in Fountain Valley, California. The company operates 51-100 employees and is associated with Twining Consulting, a full-service engineering and construction material testing firm founded in 1899 that has served California for over 125 years. Together, the entity offers geotechnical engineering, construction material testing, special inspections, forensics, concrete engineering and research, quality assurance/quality control management, vibration and geo-instrumentation, stormwater inspection, balcony bill inspections, and a recently developed 'Concrete Insight' service line covering carbon-neutral concrete, service life modeling, and mass concrete thermal control. Its materials testing laboratories are certified, accredited, and/or inspected by US Army Corps of Engineers, Caltrans, DSA, HCAi, LADBS, AASHTO, IAS, and the US Department of Housing.

RADCO/Twining generates revenue through professional services on a B2B project-based model with quote-driven pricing tied to scope of work, project size, and service requirements. The company serves seven primary verticals: Energy (power plants, renewable, pipelines), Public Works, Healthcare, Private Development, Education, Transportation, and Industrialized/Modular Buildings. Cumulative project metrics include $80M+ in energy services since 2015, $100M+ with California public agencies, $1B+ in California private development, 2,000+ healthcare projects, 75,000+ public works projects, and 10,000+ private and public sector clients. The go-to-market motion is enterprise field sales with direct website CTAs for 'Request a Proposal' and 'Request Lab Labels', supported by content marketing, white papers, and a presence across LinkedIn, Facebook, Instagram, Twitter, and YouTube.
