Building Wisconsin: Decades of Trusted General Contracting Expertise

Even after four decades in business, general contracting remains our delivery method, and we prefer to be involved up front in the design process. With Altmann Construction as your contractor, we take full responsibility for cost control, risk management, and scheduling, keeping your project on track.

In a traditional general contracting delivery method Altmann would become involved with the project once the design phase has been completed. As your General Contractor Altmann is responsible for controlling the day to day work on site and ensuring compliance with the contract documents from the initial excavation all the way to the project closeout.

Our experienced teams also self-perform critical aspects of the construction process, including site work, concrete, carpentry, and masonry, ensuring superior quality and control over the project’s progress.

From pre-construction planning to project closeout, we work with your best interests leading the way. That’s why clients across central Wisconsin trust Altmann Construction for their commercial and industrial construction.

Firm Commitments to Timelines and Budgets

No one likes unexpected costs and project delays. Developed over decades of work, Altmann Construction’s general contracting process protects your timelines and budget.

As your general contractor, we’ll use methods like these to provide superior construction you can rely on:

Detailed Preconstruction Planning – We mitigate risks and prepare for possible issues early. Conducting thorough site evaluations, estimating costs accurately, and creating a realistic project timeline helps prevent unexpected delays and budget overruns before construction begins.
Proactive Risk Management – We know what needs to be done. Identifying potential challenges early, securing necessary permits on time, and addressing supply chain issues before they impact the schedule keeps the project moving efficiently.
Efficient Coordination – Streamlining communication between you, the architect, and our teams ensures that work progresses smoothly, deadlines are met, and quality standards remain high without costly change orders.
Strict Cost Control Measures – Tracking expenses in real-time, negotiating competitive material pricing, and minimizing change orders help you stay on budget.
