Scope and inputs to reconcile
For underground work, identify trench/bedding and penetrations from details. For aboveground work, identify supports, access and specified insulation.
Workflow and checks
Classify each route by installation environment, reconcile the transition at slab or building interfaces and record quantities once.
What the output should show
Produce separate quantity groups and associated earthwork/support schedules with explicit handoffs.
Exclusions and unresolved decisions
Burial depth, support spacing and restraint design require project information rather than a universal estimating allowance.
Documents to share for a quote
Provide trench sections, support details, elevations and the below-slab/aboveground scope split.
