The design process
The process can start once we have received the architects design drawings. We then use HSB CAD to create a timber frame design. From this CAD we can then produce cutting lists and material lists. Production drawings are fully networked to the factory floor making this process a lot smoother. We then use CAM to get started on the manufacturing process. To keep track of everything, IFC files are integrated into a BIM vision, so we have access to every bit of information about individual projects, all in one place.
Because of this detailed process, it results in high levels of accuracy when it comes to the manufacturing stage and the final product.
A key advantage to the design process at FastHouse is waste reduction. Using the production drawings, a precise materials list can be produced. Because of the high levels of accuracy when it comes to the manufacturing stage and the final product, we can minimise waste on site as the majority of waste is created in our factories. This not only makes the construction site safer but it also makes it easier to navigate.
