The mathematical formulas option allows developing formulas in order to accomplish the calculation of excavation, backfill and waste material quantities for bedding and cover per pipe, per trench section.

The main features are:

• Seize the minimal requirements for excavation per pipe, for each trench section;
• Defines the vertical interval, the excavation slope, the density and the swelling and compaction factors per soil type, per trench section;
• Identifies type of soil/material to use;
• Calculates truck cycles;
• Determine excavation productions and pipe laying time.
