This Town is Your Town

Spalding DeDecker provides municipal infrastructure design, construction engineering, and rehabilitation for townships, cities, counties, and state governments.

What’s in your water?

History should be kind to engineers. Municipal engineering brought order and sanitary systems to the urban environment. The team at Spalding DeDecker has a passion for clean water and working infrastructure. And when we’re not working, you can find us volunteering to clean up rivers and making playgrounds safe for kids.

“Spalding DeDecker has served the City of Troy [Michigan] in several engineering capacities for nearly ten years. They have the professional capabilities to provide the engineering resources and expertise required for each assigned project.”

On the Road Again

After a clean glass of water, good roadways keep us moving. Construction and maintenance technology combined with our team’s experience, result in solid roads and cost-effective rehabilitation. Here’s a hint to getting more road for the buck: our team of community engineers is able to creatively assemble project funding plans from a wide variety of sources: State and Federal Grant and Loan programs, Community Budgets, and Special Assessment Districts.
