Quality Control Checklist for Excavation Work

August 18, 2017

Adherence to the upcoming quality control checklist will ensure site excavation work is carried out methodically, from the arrival of the first excavator to the laying down of the final back filled load of topsoil. Absolute procedural control is the goal here, and that goal becomes that much easier to realize when a poorly coordinated process adopts a controlled, properly managed approach to this potentially hazardous operation. Let's begin with excavation planning.

Excavation Planning

An engineering checklist is a tool, not one that lifts earth or constructs buildings, but it's most definitely an invaluable tool, nonetheless. At the top of that list, the site configuration gets unreserved attention. Photos are taken of the area before a shovelful of earth is removed. Visually record progress by continually taking pictures from different angles.

Interpret Soil Boring Reports

Difficult trenching conditions hamper the excavation work. Carry out test borings before the digging commences. By following this guideline, an accurate map of the subterranean geography is compiled. Consult the logs to gauge the elevation of site hazards, including the local water table and other geotechnical obstacles.

Call in Supplementary Systems

Floodlights illuminate the site when the sun sets early. Water pumps keep the trench dry and accessible if the aforementioned water table sits high. Likewise, skips and flatbed trucks need to be deployed when surface spoil hampers progress.

Concluding Site Preparation

Spray painted lines mark the routes of utility channels. The cable tracing service has tagged all of these runs, plus a utility map has been used to locate other services. Now that these concealed ground features are properly traced, the excavator is informed of the optimal dig route.

Check Border Zones

The existing services are found, prepared for possible rerouting, and all stake out lines have been set out. Next, establish site roads, haulage areas, and disposal sites.

Checklist Methodology: Leverage Sequential Benefits

Employ the services map as a means of avoiding loading damage when the excavator travels on-site. Follow this step with drainage and material removal solutions so that the site spoil and ground water are continually removed from the trench.

The excavation checklist is followed by structural work, by trench buttressing and soil compaction procedures. Cables are laid, foundations poured, utility services are inspected, and other important duties are accomplished. Meanwhile, safety signage is erected, worker safety procedures are enforced, and the backfill stage arrives. From here, the excavation is concluded, the soil is compacted, and the site is restored to its former pristine condition.
