What Weaver Consultants Group does

Weaver Consultants Group is a privately held, employee-owned multi-disciplinary engineering consulting firm founded in 1991 and headquartered in Chicago, Illinois. The company operates approximately 19 offices across the United States with roughly 425 engineers, geologists, environmental scientists, CQA technicians, surveyors, industrial hygienists, drone pilots, and project managers; the broader Weaver Companies network reports over 600 employees across 23 offices. Services are organized into three core lines: Solid Waste (permitting, design, construction quality assurance, operations support, monitoring and compliance, odor control, and sustainability), Environmental Services (air, water, land, environmental health and safety, remediation, and sustainability), and Civil Survey Geotechnical (civil engineering, geospatial surveying with drones and 3D laser scanning, geotechnical engineering, construction materials testing, and landscape architecture). The firm delivers more than 100 professional services and bundles them through in-house teams to limit the need for third-party contractors.

Revenue is generated through fee-for-service, project-based consulting engagements priced according to scope and complexity, ranging from small assignments to multi-million-square-foot CQA projects involving over 2,200 rolls of geosynthetics and 7.7 million square feet of material on a single project. Notable technical assets include proprietary science-based odor control systems (70+ deployed), custom-built leachate and gas condensate pumping systems developed with Sligo Systems, a mobile reverse osmosis treatment system co-developed with RODI Systems, and automated in-situ chemical oxidation remediation systems. The go-to-market motion is direct enterprise field sales with an owner's-level-of-care service model, supported by an integrated Weaver Companies ecosystem (Landmarc Environmental Systems, Anchor Construction, Sligo Systems) and a project portfolio website that serves as the primary marketing surface. Customer segments span government (Mesa County, CDOT, City of Cedar Hill, Golden Urban Renewal Authority), enterprise solid waste and real estate developers (Pine Tree Acres, Scannell Properties, Hilco Redevelopment Partners, Panattoni), industrial clients (National Steel, Wendy's), and institutional customers (University of Chicago Medicine, University of Illinois, Association House of Chicago).
