Drainage estimating built for civil contractors — stormwater, wastewater and watermain takeoffs with real trench build-ups, structure counts and rates you can defend.

From one measured pipe run Fieldlink derives the trench: excavation, bedding, pipe surround, backfill and spoil — using widths and bedding read from your typical details, all editable before approval.
Yes — measure the run on the calibrated drawing, set average depth (or let the AI Plan Reader derive it from lid and invert levels), and the trench quantities follow automatically.
As counted structures with depth and diameter metadata. The AI Plan Reader can also read manhole schedules and combine lid/invert levels so each structure carries its real depth.
Yes — trench build-ups calculate excavation, bedding and backfill volumes (less pipe displacement) from length × width × depth, with every value editable.
Yes — add them as line items with rates from your Rate Library so CCTV, pressure testing and surface reinstatement never get missed at tender time.
Fieldlink is built in NZ for NZ civil work — DN pipe sizing, RCRRJ/PE/PVC materials, stormwater/wastewater/watermain disciplines and NZD pricing throughout.
