What It Is

Affinis is a civil engineering, surveying, and consulting firm based in the Kansas City area in the United States. Its website positions the company as a Kansas City Engineering Firm. Founded in 2001, it was formerly known as Larkin Group Consulting Engineers before being renamed Affinis. The company emphasizes long-term client relationships and the idea of “making clients’ work easier.” Its main clients include owners of municipal, state, federal, and private infrastructure projects.

Core Features

Affinis provides services across roadway engineering, traffic engineering, stormwater management, structural engineering, geotechnical engineering, and Survey/UAS mapping. Based on its project pages and blog, its work includes community road improvements, ADA-accessible sidewalks, roundabout design, stormwater and flood mitigation, water quality improvements, and utility and drainage system upgrades. Its strength is not simply delivering design drawings, but providing integrated consulting from preliminary studies, site investigations, option analysis, and engineering design through to constructability and budget control.

Pricing

The website does not publish a price list or standard packages. Engineering consulting of this type is typically quoted individually based on project scope, required disciplines, site conditions, design depth, approval requirements, and timeline. Pricing may be structured as a fixed fee, hourly billing, or under a government procurement contract. Prospective clients need to discuss requirements via the contact form, phone, or email.

Pros and Cons

The main advantages are its strong display of professional qualifications, with team members holding roles and credentials such as PE, PLS, PTOE, and CFM. It offers a complete service chain and is backed by extensive client testimonials and industry awards. For public-sector engineering clients, its emphasis on the MoDOT LPA process, capital improvement projects, federal services, and construction-ready documents suggests familiarity with local government project workflows.

The drawbacks are that the website functions more as a corporate showcase and lacks quantifiable pricing, delivery timelines, an online project management portal, or downloadable technical white papers. Its business is also highly regional. For clients outside the U.S. Midwest, especially overseas clients, its practical usability is limited.

Who It’s For

Affinis is best suited for municipal public works departments, county governments, transportation and water-related agencies, developers, and project owners in Kansas, Missouri, and surrounding areas that need local surveying and civil engineering design support. It is not a good fit for users looking for online tools, standardized software services, or cross-border remote engineering outsourcing.

Access from China

The website mainly consists of static English-language pages and is generally accessible directly from mainland China. However, because its services involve U.S. local regulations, professional licensing, and on-site surveys, it has limited practical value for Chinese clients unless they have projects in the United States.
