Nearly 50 years of building systems upgrades and engineering experience
Engineering companies specializing in high-volume, high-traffic commercial, academic, and industrial buildings are rare. And MEPT consulting firms you can trust with specialized skills you can depend on are even rarer.
When your facility, architecture, or construction crews identify a need to add or replace boilers, chillers, refrigeration, air, hydronic, or energy management systems, trust R.E. Dimond’s mechanical engineers.
MEPT services based in Indianapolis, Indiana
Get innovative engineering ideas to bolster your construction, infrastructure, and renovation teams. We provide direct support services for:
- Architects and architecture firms
- Corporate clients
- Institutional clients such as schools, hospitals, and universities
- Municipal buildings such as courthouses, jails, city and town halls, and other local government facilities

Every engineering project we do goes through three steps:
- A preliminary study reviewing existing construction documents to project needs, timeline, and scope.
- Team integration into your existing schedule, architect, contractors, or other team members.
- A review during and after each project, renovation, or upgrade to identify future needs.
Central Indiana mechanical engineers leading the industry in focus and expertise
