Truck Loadout Facilities Improvements Design

Opal Group, Inc. prepared Design Drawings and a Construction Management Plan for improvements on a truck loadout facility at this fertilizer manufacturing facility. The plant includes four adjacent truck scale pads, where trucks are loaded with up to 5,000 gallons of liquid fertilizer per load. The mechanical scales have recently been replaced by a flow metering system rendering the scales no longer necessary. Opal also provided construction oversight, scheduling and as-built documentation for the two phases of the project.
In order to mitigate concerns regarding health and safety, overspill containment, and stormwater control, the following modifications were implemented at the KNC truck loadout facility:
- Removal of the scale plate and underlying mechanisms as steel scrap within the concrete scale pits;
- Cleaning of the inside concrete surface of the scale pit;
- Pluging and abandoning the existing drain system on the loadout pits;
- Installation of a new trench drain with underground piping system within each pit and loadout area upon completion of backfilling operations and was connected to an existing sump;
- Backfilling and engineered compaction (in lifts) using structural fill within the scale pits to near the top of the pit walls;
- Pouring of a sloped concrete slab to the drain within the confines of the scale pit walls;
- Concrete areas underneath pipe racks between scale pits replaced and sloped appropriately;
- Demolition of an existing berm system on the access and exit driveways.
