Estimating and Project Management

Our staff has a combined 60 years of experience estimating and managing structural steel projects while interfacing and cooperating with engineers, architects, owners, purchasing agents and general contractors. We use special state of the art project management and estimating software to help save our customers money and more importantly, time.

Detailing and Drafting

Clear fabrication details are prepared using state of the art Design and Detailing Software, with plans being fully modeled to ensure a complete understanding of the project. At Mazzella Welding we use the top detailing firms capable of interfacing with BIM, or Building Information Modeling, is the practice of building a computer-generated 3D model prior to actual construction. We also have the capabilities to draft and detail, in house, miscellaneous and small structural work using AutoCad software.
