For more than 40 years, utility owners and project leaders have trusted Day & Zimmermann to keep their projects on time and bring reliable power online. That’s because they know D&Z builds and maintains coal, gas, and hydro plants that meet the highest standards of safety, performance, and efficiency. We bring that same proven capability to the design and construction of your new gas-fired generation.
Whether you’re facing regulatory deadlines, investor scrutiny, or tight commissioning schedules, we understand the pressures you’re under — and we’re here to help you succeed.
We do what we say® so that our customers can do their best work better.
You don’t need just a contractor. You need a construction partner who listens, responds, and delivers. At D&Z, we build strong alignment across engineering, procurement, and construction teams to reduce rework, prevent change orders, and eliminate the disconnect between the design and the field.
We offer complete EPC solutions as well as construction-only delivery models, tailoring our approach to your project’s scope, risk tolerance, and preferred execution strategy. The result? Fewer surprises, stronger coordination, and a more efficient path to commercial operation date.
Our EPC offering is purpose-built for utility-scale fossil projects — driven by a deep bench of multidiscipline engineers, experienced procurement professionals, and construction leaders who understand the complexity of high-stakes power projects. Whether it’s greenfield or brownfield, regardless of your labor needs, we take full accountability from design through commissioning.
Multidiscipline Engineering – Integrated civil, structural, mechanical, and electrical design that balances constructability, operability, and cost efficiency
Smart Procurement – Strong supplier relationships and disciplined material management that minimize lead-time risk and avoid costly delays
Integrated Project Controls – Tight alignment across scheduling, cost, risk, and performance metrics keeps stakeholders informed and projects on track
Constructability-Driven Approach – We build with construction in mind from day one — avoiding field disruptions, eliminating waste, and accelerating schedule
Whether you need a true turnkey EPC partner or hybrid delivery, we work with your internal teams and selected vendors to ensure seamless handoffs.
Regardless of labor stance, D&Z tailors our approach to meet each customer’s specific needs. In union projects, our long-standing relationships with the Building Trades and understanding of labor agreements allow us to collaborate closely on craft planning and resource alignment. In open shop markets, we leverage strong community ties, partnerships with community colleges and training programs, and our proprietary recruiting tools
Across both models, we focus on workforce quality, flexibility, and reliable, long-term labor solutions that connect customers with the right talent and support project success, even in today's tight labor market.
Most of our leadership started as craft professionals. They’ve managed the same pressures you face — and know how to solve them. That experience fosters better communication, faster decision-making, and smoother project execution.
Our proven, best-in-class safety program is embedded from day one — supported by technology, training, and accountability at every level. We don’t just preach safety. We prove it, with industry-leading performance across fossil and industrial projects nationwide.
From initial planning through commissioning, we’re ready to work with you to deliver the best value, least risk, and most efficient path to completion. Let’s talk about how D&Z can support your next generation build with unmatched certainty, safety, and project delivery excellence.
