Why contractors should consider working with BIM

To set the general scene, let’s first look at a more general construction project to highlight the benefits of using BIM in different project phases. Prior to starting construction work, BIM has huge value for contractors to optimize coordination. The better the coordination between design professionals and contractors, the fewer mistakes happen and less unnecessary additional cost is generated which often eats into a contractor’s margin. A 3D BIM model enables contractors to clearly understand the expectations of project owners and architects. Not only can they assess cost and manage risks, crucially they can also point out flaws in the design to avoid additional work and expenses later on. Particularly in relation to error detection and related cost savings, the power of BIM cannot be underestimated. While a conventional 2D drawing might leave you with the impression that, essentially, everything with the structure in question is alright and work can go ahead, a detailed 3D BIM model will detect structural mistakes that could generate considerable additional cost in the end, not to mention the knock-on effects on keeping the schedule and making the client happy.

During construction, BIM is a great tool for organizing and tracking work. Contractors can, for example, assign tasks and monitor progress, updating the model as the work progresses. Schedules can also be linked which is a great help in an environment where time is always of the essence and clients will appreciate up-to-date information on progress. The data-richness of BIM models also supports contractors in the post-construction phase when providing maintenance services. Detailed information on components installed makes it easier to address issues when they occur after construction has finished. Clearly, to fully benefit from these BIM capabilities, actually investing in a corresponding software is advisable and, ultimately, worthwhile.
