A large commercial slab takes shape across a Portland jobsite. This project gave Wallace Construction a broad slab-on-grade footprint to work across, with the scale of the placement immediately visible in the field. Slab-on-grade refers to a concrete slab placed at ground level as part of a building’s floor or foundation system. In the project photo, a wide section of freshly placed concrete fills the foreground while crews continue working across the active placement area. The defining feature here is not a decorative finish or a small isolated concrete pad. It is the size of the commercial concrete operation and the coordination visible across the site. A Commercial Pour Defined by Scale and Coordination Large slab-on-grade work brings multiple moving parts into the same footprint. The photo shows concrete placement equipment reaching over the work area, workers positioned at different points on the slab, and numerous vertical penetrations extending through the surface. At this scale, the pour itself becomes a coordinated field operation. Placement Equipment Reaching the Work Area A concrete pump boom is visible above the site work, providing reach into the slab area without requiring the concrete delivery point to be located directly beside the placement. Its position…
