The Project
This project is an expansion of one module to an existing metal building. It was 1,100 MT job with cranes and a mezzanine structure
The Challenge
The biggest challenge was to connect the new building to the existing metal building, which was not constructed by us. Also needed to connect crane brackets for crane beams on existing columns and where another hurdle was existing columns were to be strengthened with extra web and flanges to take future loads of crane.
The Solution
Before doing a detailed schedule, we made a survey of the existing building with a total station, and we found that existing columns were not in a straight line and a lot of columns were out of plumb. We decided to keep new building columns in a straight line and made crane brackets of variable length so that we get crane beams and rail above beams in a straight line. The overall task was challenging to weld overheads and overcome fire hazards, which was controlled by making fire blankets booths around welding areas. In the end, the task was completed with accurate alignment and the end client appreciated our work.
