Pre-fabrication services bring the client, content developers, designers, and project managers/fabricators together to develop an execution plan that will achieve the project’s interpretive, schedule, and budget goals.  During pre-fabrication consulting, we work with the client and the client’s designer to analyze the project’s build-ability. Our engineering team builds the project in Autocad to test proof of concept, while the Lead Estimator produces interim budget analyses and the Project Manager develops preliminary schedules. We recommend project approaches based on our knowledge and experience, as well as the client's budget and priorities.
