Design-Build vs. EPC Method in Fast Paced Schedules
Design-Build and Engineer-Procure-Construct (EPC) are both methods to construction for agricultural buildings. In a lot of ways, they are similar methods to getting your new building. They both offer a single point of contact between contractor and owner, the contractor is the head of design once the project is started, and the contractor is picked by the owner. However, there are key differences that can either make, or break, your costs.
Engineer-Procure-Construct (EPC) Method
In this method, the contractor is responsible for gathering all of the materials, designing the building, and construction. The single point of contact is for alerting the owner of the progress of the build. The cost is a lump sum of all aspects of the materials and build. This method has been preferred for many years because the timeline, scope, and costs are estimated before the build with little hands-on involvement from the owner. However, the little involvement can lead to miscommunication about specific design aspects between the owner’s designs and the contractor’s interpretation.
Design-Build Method
The design-build method is gaining momentum and is becoming the most used contract method, and for good reason. In this method, the contractor is hired by the owner, who guides the owner through the design process before estimating the cost, scope, and timeline. The owner and head contractor communicate through a single point of contact. The cost is usually a lump sum as discussed with the owner during the design process to match the owner’s needs. This allows for clear communication of what the owner is looking for and what the contractors can do to fit their budget.
Key Differences to Consider
Between the EPC method and the Design-Build method, it seems like costs and timelines would be similar because the contractors still do most of the work in getting materials and construction. The main difference seems to be only in the design process. However, working with the owner on the design, like in the Design-Build process, will lead to many benefits. Working with the owner in the design process allows contractors to find ways to fast track their progress on the build. There are also more details shared with the owner to maintain superior performance while working on the build. Thirdly, there is far less risk being taken when the design is a collaboration, rather than a hand-off.
