Residential Streets
Our team has a passion for street design and is skilled at gaining stakeholder support. Our detailed designs address project constraints while adding value with special features. This is best illustrated by our track record of successfully completing projects on-time and under budget.

We love our work and strive to make it the best it can be. A senior engineer leads each project, and every member of the team is equipped to handle questions and provide support.  Our quality assurance and control procedures ensure our bid documents clearly and accurately convey the project design, allowing contractors to be more competitive with their bids.

Thoroughfares/Highways
Designing thoroughfares and highways is often a balancing act, and it’s one at which our team excels. With any project, we work with a variety of stakeholders. We partner with city, county, and state agencies. We understand their requirements, and they are familiar with us. All of these factors facilitate productive project meetings and aid in collaboration.

While these relationships are important, public partnering is key to a project’s success. Our team is adept at generating consensus by explaining improvements in lay terms. This skill has helped us successfully take miles of roadway from design to construction.

Traffic
Great traffic design is in the details. Developing concepts and analyzing alternatives to create cost-effective designs is something we do very well. Whether using detailed decision matrices or simple reports, we can clearly illustrate the advantages and disadvantages of proposed solutions.

Our traffic team understands having the right data is just the beginning. We analyze traffic data in existing and proposed conditions and then, develop geometric and system improvements to increase safety and expedite traffic through a project. Managing access during and after construction is critical to gaining public support.

The City of Leawood needed the signal design at 133rd and Roe fast tracked. Affinis delivered quality plans in six weeks and provided excellent communication throughout the process.
