Building Information Modeling (BIM)

Building information modeling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of places. Participants in the building process are constantly challenged to deliver successful projects despite tight budgets, limited manpower, accelerated schedules, and limited or conflicting information. The significant disciplines such as architectural, structural and MEP designs should be well coordinated, as two things can’t take place at the same place and time. BIM aids in collision detection at the initial stage, identifying the exact location of discrepancies.

At Sure-Fire Mechanical, we have the latest version of Autodesk Revit that allows our team to get out in front of problems before they happen. With a number of projects under our belt, we have the experience and skills in-house that make us able to offer this service to our customers to help deliver a project within their budget and timeline.
