Basics- How to build using 3D Concrete Wall panels in, Dubai
ABU DHABI MUNICIPALITY AND TOWN PLANNING
YEAR BUILT 2001 & 2002
200 Accommodation units built with 3-D Concrete wall panels
Systems at Al Samha
Contractor Emirates Buildings ABU DHABI
3-D Panels installed for a multi level, three story structure.
The 3-D Panels erected are the walls, floors and roofs. The TridiPanels on this project were installed one floor at a time, you can see the concrete bond beam connection at each level.
You save on labor with prefabricated panel construction, and cost of materials with a minimum of waste or scrap, the panels are cut to the length required and the panels can be cut in eight inch increments.
The SCIP building system has a unique scaffolding construction, it must be engineered to the specific job, allowing the shotcrete team to move quickly, with additional space and mobility for the concrete scraper, and darby smoother who follows behind the nozzleman, both need to have the proper arm reach to the panel wall. We have an in house shotcrete team, so we are prepared for the cleanup of concrete from over spray onto our scaffolding, we have workers setting and placing planks throughout the day when we spray. Engineered scaffolding designed for a specific build is required on the exterior walls and interior walls and ceilings. This is a hidden cost that most contractors or builders don’t include in estimating.
Take notice of the floor to wall connections, the concrete beams, the Panels are set in place one floor at a time.
Up close this view of the building system, zooms in on the rebar, which is placed over the polystyrene foam, or Panel. It is a nine gauge welded wire mesh, the nine gauge galvanized wire is welded to each side of the panels two inch by two inch wire mesh, the Portland cement or shotcrete, when placed strengthens this welded wire, creating a structural load bearing wall system.
In this image you can see the screw jacks and shoring to support the 3-D Panel roof and floors. I sometimes install this after the panels have been set in place. The panels will take the span, the shoring is necessary to hold the panel’s level straight while applying Portland cement or shotcrete.
This is the wall to floor connection, the void will be filled with concrete; rebar will be installed to receive the upper level of panel walls.
Preparing to pour concrete forms have been placed, shoring has been placed under the panel floors, concrete will be poured on top of the panel floors, the rebar standing straight up will receive the next level of panels.
