Handhole
A below-grade access box for pulling and splicing underground cable.
Quick Answer
A handhole is a below-grade enclosure with a removable cover that gives access to underground conductors or cable for pulling, splicing and maintenance, smaller than a manhole. Estimators count each handhole EA from site and utility plans and carry excavation, backfill and the cover rating separately.
The Full Picture
A handhole is a box set in the ground along an underground conduit run. Crews reach into it, and do not climb into it, to pull cable, make splices or add a branch. Utilities use handholes for electric and communication lines, and site electrical designs use them for parking-lot lighting, security, irrigation controls and campus cabling. California's utility rules, for example, define a handhole as a permanent opening in an underground system, usually smaller than a manhole, with a removable top.
The drawings that define handholes are the site plan and the underground utility or site electrical plan, with a detail sheet for the box. The plan shows each handhole as a symbol, usually numbered, along a conduit run, and the detail gives the size, the cover legend such as ELECTRIC or COMM, the base material and the cover load rating. The electrical and civil specifications set the material, which may be precast concrete, polymer concrete or plastic, and the traffic rating. Where handholes sit in a roadway, the same California rules require that those in vehicle-traffic street areas withstand H-20-44 highway loading, which is one example of a load rating driving the product choice.
The takeoff unit is EA for the handhole, described by size, material and cover rating. The excavation is measured in CY, since each box needs a pit larger than the box, and the base or bedding stone and backfill are measured in CY or tons. Conduit entries, end bells or bell ends, grounding and the cover marking are carried as EA or by the handhole as the spec allows. Trench and conduit between handholes are measured in LF on separate lines.
Typical mistakes are counting the handholes from the electrical plans but not the civil plans, which may show more, pricing a non-traffic box where the detail calls for a traffic-rated one, and leaving out the pit excavation and the crushed stone base. Another is mixing up handholes with larger vaults and manholes: those are entered by workers, are priced differently and may bring confined-space requirements.
Real Examples
Common Misconceptions
People assume: A handhole is just a small manhole.
Actually: The defining difference is that a handhole is reached into and not entered. Manholes and vaults are entered by workers, and carry confined-space and structural implications that change the cost.
People assume: The handhole price is the box price.
Actually: The box is one part. Excavation, bedding stone, conduit entries, grounding, backfill and surface restoration also belong to the handhole's scope.
Does MeltPlan Solve This?
Partially — adjacentCounting handholes from site electrical and utility plans, and measuring the conduit between them, is takeoff work. MeltPlan's takeoff service uses AI to pull quantities from PDF plans, and US-based experienced estimators review and adjust them. Picking box size, cover rating and who furnishes the box stays with the engineer and your estimating team.

What is a handhole?
It is a below-grade enclosure with a removable cover that gives access to underground conductors for pulling, splicing and maintenance.
How is a handhole different from a manhole?
A handhole is smaller and is reached into, while a manhole is large enough for workers to enter.
What unit is a handhole taken off in?
EA, with excavation in CY and conduit in LF as separate lines.
Do handholes need traffic-rated covers?
Where they sit in vehicle areas, yes. The detail and specification set the rating. For example, California's rules for street areas call for H-20-44 highway loading.
