Drainlayers & Civil Subcontractors


Drainage take offs for drainlayers & civil subbies. Stormwater & wastewater LM by size and depth, excavation, bedding & pits. Fixed fee, 2–3 day turnaround.


For drainlayers and civil subcontractors who are pricing residential, commercial, land subdivision and light-civil drainage scopes across New Zealand.


Measure your full below-ground scope from the hydraulic drainage and civil drawings including stormwater, sewage wastewater, subsoil drains & pits through to works outside the boundary including connections into existing infrastructure.


Pipework is separated by type, then scheduled out in lineal meters with all pit, sumps, manholes, IO and gully trap items counted separately. Because depth drives drainage cost, the take off schedule clarifies trench excavation depth with all bedding, backfill and spoil volumes being documented so you can correctly apply the plant cost to each piece of work.


The tender schedule serves as a fixed baseline for any variations or drawing changes thereafter and makes submitting and agreeing any variations a lot easier.

FAQ

Why are drainage quantities split by depth?

A metre of 150mm pipe at 0.8m deep and the same pipe at 2.5m deep are completely different costs — more excavation, shoring, machine time and spoil.

Do you measure excavation and backfilling, or just the pipe?

Both. Trench volumes, bedding, backfill and cart-away are quantified along with the pipework. The surplus spoil leftover at the end of the drainage scope as a result of backfilling of 'approved' fill and or hardfill/bedding can either be stockpiled and left on site, or carted away and disposed of.

Where does the drainage scope end and plumbing begin?

The plumbing scope connects into the drainage. The drainage is works below ground up to any stormwater upstands, under slab pipework upstands or external gully traps. Plumbing scope belongs within the building generally.

What drawings do you need for a drainage take off?

Hydraulic drawings with invert levels, plus the relevant specification if available. If invert or level information is missing or conflicts between sheets, it will be flagged before you price — cheaper to catch it now than in the ground.
