Installing a Drop Ceiling to Hide Ductwork

Bob walks through the Manhattan Brownstone floor-through apartment with project manager Chris Vila, looking first at the ductwork that has been run in the ceiling for the forced air heat. He then joins John McEvoy of Thorough Construction for a look at the drop ceiling installation they will be using to hide the ductwork and mechanicals in the ceiling. This Chicago bar system allows the crew to hang a perfectly level drywall ceiling instead of following the uneven pattern of the existing joists. First an anchor is screwed into the joists. A pencil rod is then fitted into the hole in the anchor and bent to hang from the joist. A lasar level marks the exact position for the kelly clips that will hold the main stays or block irons in place. The Chicago bar is then clipped to the block irons with a spaghetti clip to create a grid for the new drywall. The drywall will be screwed directly into the suspended Chicago bar. More information
