Why Prefabrication, Preassembly, and Modularization?

The key to success in prefabricated, preassembled, modularized project execution lies in thorough front-end planning. Roeslein guides clients through the early stages of a project by performing capital budgeting, feasibility studies, marketing planning, and process flow diagrams to ensure a smooth project implementation.

Roeslein’s unique approach to the modular design-build construction process is to provide clients with a high-performance, integrated solution that allows for a greater return on invested capital by improving design and construction phase productivity, enhancing project quality, and speeding up systems and plant operations deployment.

Roeslein’s project management teams guide projects from conceptual design all the way through to project start-up and commissioning. Acute involvement in all aspects of project execution allows Roeslein’s project management team to cohesively manage customer-driven metrics of cost, schedule, and overall project quality.
Because Roeslein separates process implementation from facility construction the effects of delays and unforeseen circumstances on installation timetables are minimized. No matter what the project’s size or location Roeslein’s modularized, prefabricated, and preassembled approach provides consistency in the quality of the design, fabrication, installation and, most importantly, the results.
“When you practice something over and over again until it’s perfect, you end up with a team that’s capable of so much more than just the sum of its parts…”
