Through our Design-Build service, Sierra provides a single source of responsibility to the client. We work to develop and understand your project expectations and then manage those needs with a customized, qualified design team. Innovation should happen throughout the life of a project. To achieve this, we focus our efforts on each individual phase of your project to make the entire process smooth and straightforward. Our proactive, collaborative approach is what uncovers unique ideas and opportunities for improvement before the next phase begins.
This process is achieved by having all functions under one roof allowing our experienced building design, project management and construction team to maintain budget, maximize communication, minimize confusion and put your entire project on the fast track to completion providing the absolute best value for your investment.


As Construction Managers, your vision is our vision. We work closely with architects and designers to understand the project, and ultimately develop a targeted solution that optimizes every stage of the build. This allows our clients to make informed decisions with confidence. Our team engages at the earliest stages of the project cycle and sees the project through to completion—regardless of whether the construction phase is delivered through a cost plus, fixed price, or guaranteed maximum price contract.


Sierra is often hired as a General Contractor, overseeing the execution and construction of projects where the design and engineering work has already been completed.
While working with your architect, we provide quality construction services from building permits to site development through to the final occupancy of your building. We can tailor our construction services to specific portions of your project as well; such as site work and foundations to supply and erect of your pre-engineered structure.
At Sierra, our experienced professionals begin by developing a thorough understanding of your needs and expectations to provide a complete package for your project, from start to finish. Through our Open Book process, every aspect is clearly defined, including costs, materials, timelines and alternatives so that there are no hidden surprises during your project. Sierra is there, sitting on the same side of the table as the Owner.
