Division 33 / Delivered

Division 33 site utilities estimating

A utility run is priced per foot, and the price per foot changes sharply with depth. A plan that shows the run without the profile is half a drawing.

What we measure, and in what units

LF pipe by size and depth band
EA structures by type
EA connections to existing
CY bedding and backfill
SF surface restoration

What the deliverable looks like for this division

Pipe by size along the plan and by depth from the profile, banded because the trench, the shoring and the productivity all change with depth. Structures and connections counted, bedding and backfill by volume, and the surface restoration behind every connection as its own scope.

Scope items routinely missed on this division

Only someone who has priced the work knows what falls through the gaps. No competitor publishes this list.

Trench depth bands, since the price per foot changes sharply with depth and a single rate across the run is wrong somewhere.
Connection to existing, and the surface restoration behind it, which can be the largest item on a short run.
Bioretention and storm treatment structures as their own scopes with their own media and plantings.
Testing, flushing and disinfection of new mains.

Questions people in this trade actually ask

Why band by depth?

Because a foot of pipe at three feet and a foot at nine feet are different trenches, different shoring and different crews. One rate across both under prices the deep end and over prices the shallow.
