In an effort to improve their stack emissions, Muscatine Power & Water needed to convert their existing Unit #8, coal fired boiler, to be capable of burning western coal. They also needed to complete some long-term deferred maintenance work. This involved changes to the boiler and all new pollution control systems for Unit #8. They divided the project into several equipment supply and construction contracts.
Muscatine Power selected Carl A. Nelson & Company to complete Contract #7 which included auger cast concrete pile supported concrete foundations for all the new construction. This also included relocating all conflicting site utilities to allow construction to proceed.
Lead contractor, ACI Mechanical, selected Carl A. Nelson as their general trades team member to submit the winning proposal on Contract #8, which included all the mechanical, structural, architectural, and civil work to complete the project. The project was completed on a tight schedule to limit the downtime for Unit #8. All the systems were additions or replacements of existing systems that required very extensive plant wide coordination with existing conditions. Work completed included new breaching to and from the new precipitator, new ash water system, new settling and surge tanks, new fly ash reinjection system, new vacuum ash system, new coal handling system, site work, and extensive renovation of existing buildings.
The ACI Mechanical and Carl A. Nelson employees rose to the challenges of this difficult project in a team environment to meet Muscatine Power & Water’s needs and requirements.
