In order for a rooftop platform to be correctly fabricated, we feel that a pre-construction site visit is critical to success…so much so that we won’t complete one without it. What this allows us to do is perform a Ground Penetrating Radar test or GPR test on the roof deck. This will help us to determine the exact column locations so that load bearing attachments are correct. It also allows us to avoid conflicting with pre or post tension cables which is also critical to success. Also, we review what stealth construction is needed to meet client and jurisdictional requirements. From here, our in-house fabrication team takes over and builds the platform to meet the specific needs of our client.
