Preconstruction
The pre-construction phase is crucial to the success and profit of any construction process. However, the complexity and magnitude of the decisions an owner must make can be difficult without the necessary expertise and support. That’s where we can help.
Construction
Oltmans’ portfolio spans the gamut of product delivery. We specialize in ground-up construction, renovation and repositioning, seismic retrofits, and tenant improvements throughout the Southwest United States. Our self-performed construction services include concrete, SWPPP, and solar EPC.
Project Management
We place a strong emphasis on preserving the consistency of project teams once they have been assigned to your project. Along with an investment in innovative technologies we believe this creates an environment that fosters high levels of collaboration, communication, and is our commitment to each project’s successful delivery.
