At Chastain, I value the opportunity to try out different types of projects.  It has helped me to become a more well-rounded engineer and discover the type of project that I enjoy the most.  I also value the openness of management in the company.  It is okay if we don't have all the answers and we can find the solution together as a group.  Chastain also provide flexibility in work schedule and accommodates our family needs.

 Working at Chastain has been very rewarding, challenging and flat out fun.  They offer a very flexible working environment (half day Fridays) as well as being family-friendly and understanding when things do come up.  The projects are very diverse and they are always open to employees who want to spread their wings and wear many hats on a project.  My co-workers are very genuine and are always available to lend a helping hand on project related issues.

For me, the most important thing has been their willingness to be flexible with not only my hours, but the location where I do my work.  I was provided with all the necessary equipment to work from home during the pandemic, which allowed me to be there for my kids while homeschooling.  Overall, Chastain is a great company.  We are consistently being offered opportunities to be our best selves.

I like working at Chastain because of the diversity of the projects and parts of projects I get to work on. As a young engineer, it’s been very helpful to me to see so many different aspects of a project and how they all work together. In the office, I’ve worked on water and sewer projects, local roads, bridge replacements, hydraulic modeling, MFT programs, and countless others. Out of the office, I’ve done surveying and construction observation which have helped me see how the plans get from the paper to the ground. Chastain has showed me how much more there is to civil engineering outside of what they teach you in school.

Funding & Grant Services.

 In the last 5 years, we have helped communities secure $35 million 
​in grants and low-interest loans to offset ​public infrastructure costs.
While every project starts with a need, many projects stall or never take off because of inadequate financing and support. At Chastain, we understand how important funding and grant sources can be for a project.  We can guide you through the critical process of garnering support for your project, combining funding sources, managing the various timeliness, and taking care of the crucial details that satisfy the fund source requirements. 

We want to work with communities to improve their infrastructure in a financially sustainable way that will not cause an undue financial burden.  Read more...​

​Compared to the other HSIP grant projects the City has implemented recently, this project was by far the most successful at staying close to the 90/10 actual split. Chastain did a great job here controlling the costs of this project.  - City of Rockford
