1. Formwork Erection for Civil Engineering (Bottom Formwork)

The elevation control for bottom formwork erection in civil engineering follows the same strict acceptance criteria as the design drawings and construction specifications, with firm scaffold support. Note that the fair-faced concrete floor/slab is constructed synchronously with concrete pouring. To facilitate mechanical construction, there shall be no formwork or fasteners protruding above the floor elevation, except for pre-reserved and pre-embedded components as specified by the elevation requirements.

2. Steel Bar Binding

Since the surface layer is a one-time cast floor/slab utilizing the concrete cover of reinforced concrete, sufficient concrete cover must be ensured during steel bar binding. No steel bars, stirrups or welded parts shall be exposed on the concrete pouring surface in violation of specifications—such exposure may cause the machinery to hit the steel bars, damaging both the machinery and the concrete surface layer.

3. Concrete Pouring Control with Laser Level

Set the elevation on the column reinforcement before concrete pouring, and transmit the accurate elevation to the laser level control system. During rough leveling, concrete pouring personnel shall control the elevation to 5–10 mm above the design elevation, laying a solid foundation for subsequent laser screeding.

4. Concrete Leveling with Laser Screed

With the elevation accurately set by professional technicians, machine operators perform precision leveling on the concrete surface under the control of the laser level. The screed automatically calibrates itself at a frequency of 10 times per second to ensure the precision of the leveled surface.

5. Precision Leveling by Professionals

This process is carried out after the bleeding of the concrete pouring surface is completed. Recheck water puddles with the laser level and fill them with concrete; perform 360° rotary screeding on the surface layer with a 3m screed to achieve overall flatness control, and smooth the details at the edges of formwork around column bases. Repeat inspections with the laser level until the requirements are met.

6. Slurry Lifting & Troweling with Single-Disc Troweling Machine

During the standardized and sequential concrete pouring, take advantage of the construction time difference: the early-poured concrete will reach the initial set stage earlier (when a 2–3 mm footprints is left on the concrete when standing). At this stage, use a single-disc troweling machine with troweling discs to perform cross slurry breaking and troweling, ensuring flatness control during mechanical operation.
