Additional Services


Our prefabrication team has allowed Tapani Plumbing to complete jobs with greater efficiency while maintaining the high level of quality that keeps our valued clients returning to us for their projects. Prefabricating plumbing components in our shop rather than on the jobsite has many benefits for our clients including a reduction in onsite labor and waste, less on-site hours and lower safety risk.

Building Information Modeling (BIM)

By transitioning our pipe routing to digital BIM programs, we’ve reduced our onsite deck layout time by up to 80%, providing our customers with valuable extra time during structure erection. The use of 3D modeling allows us to get an in depth look into the building long before we are on-site, which helps to visualize and detect routing or location constraints before any labor or materials has been invested.
