Aristeo Construction managed the construction of Invenergy’s 60-turbine Crescent Wind Park in Hillsdale County, MI, creating the first industrial wind farm in southeast Michigan, and the fourth largest in the state.
AGC of Michigan Build Michigan Award for Construction Excellence
Our years of experience and more than one million total manhours in wind construction resulted in the successful completion of the Crescent Wind Park in 2021. Our skilled trades team members, certified by both OSHA and the Board of Certified Safety Professionals, completed the project within the nine-month schedule with more than 144,000 manhours on record for this job. After a successful handoff in early 2021, the wind energy farm helps fulfill local clean energy initiatives while meeting customer needs with renewable energy and net-zero carbon emissions.
We managed the entire project including more than 15 subcontractors and suppliers to build the first industrial wind farm in southeast Michigan, as well as the fourth largest in the state at 166 megawatts (MW). This 60-turbine park in Hillsdale County, MI generates enough energy to power 64,000 homes and includes 54 GE 2.8 MW turbines with 127-meter rotors and 89-meter towers, as well as six GE 2.4 MW turbines with 116-meter rotors and 80-meter towers.
Aristeo’s scope of work as the general contractor included leading comprehensive and proactive project planning and overseeing everything from site work and access road installation to turbine erection and site restoration. Our detailed logistics plan safely and efficiently brought in large, heavy equipment and materials to the remote jobsite, prepared the location to physically support the heavy materials including moving more than 225,000 cubic yards of earth to even out the terrain, sequenced activities for the most efficient outcome and ensured the project would finish on schedule and on budget. The project also included excavation and backfill, steel reinforcement, foundation installation, crane pad installation, tooling calibration and maintenance, anchor bolt assembly and alignment and more.
This project was unique because the terrain in southern Michigan is hillier compared to other wind farms in the state. This made deliveries, moving equipment and erecting the turbines a challenge. Thanks to detailed planning, we were able to work with Invenergy to make the site accessible for delivery trucks and large cranes. We also developed an efficient and cost-effective crane set-up, which allowed for high performance and easy mobilization across the difficult terrain. Landowner relations were another important factor to the success of this project, due to the wind park’s location on local community members’ properties. Thanks to our proactive communication, ongoing relations remained positive.
