Basic Services

Every day, Ratibor DOO advocates for our clients’ best interests. We provide leadership during each phase of their project. Our team delivers preconstruction consultation and estimating services during the design phase, as well as effective on-site management services and strict quality control procedures while the job is being built. We have a thorough understanding of the many complex aspects of the project and the ability to identify potential scope and system improvements, resulting in the most time- and cost-effective building experience possible. By working closely with the client from design stages to completion, the knowledgeable team at Ratibor DOO provides experienced management and control throughout the design and construction process, saving time and money.

Our Construction Manager at Risk (CMAR) process focuses on collaboration with the client and design team. It is our job to maximize the scope of the project by providing clients with strong preconstruction estimating and value engineering services throughout the design phase. By proactively working with the owner and design team from the initial stages, we are able to offer valuable insights on cost-effective mechanical and electrical systems, structural components, and site requirements. Our input is utilized to develop a realistic project schedule and budget. Once the job is started, Ratibor DOO provides effective and quality-driven onsite leadership during the construction phase of the project, to maintain the schedule and meet owner deadlines.


Utilizing Ratibor DOO as the Design-Build (DB) contractor allows us to work as the client’s Single Point of Contact for both design and construction of the project. Design-build delivery focuses on saving time and money by overlapping many aspects of design and construction activities. This method is proven to be the fastest approach to completing a building project. As the DB contractor, we lead and direct in the earliest phases of design, and are able to offer invaluable insights for solutions and recommendations to maximize your budget. Our team approach utilizes the skill sets of each specialized team member and their area of expertise, to see your project from beginning to end.
