Bring these documents

The drawing register, trade plans, scope descriptions and addenda.

Mistake to catch

Adding two subcontract quantities for the same component, or missing a scope transfer after an addendum.

Run this demo test

Choose a component that two packages mention. Assign its quantity owner and record the other package's exclusion. Revise the assignment and inspect both package totals.

Construction takeoff workflow

Site, civil & geospatial

Identify inlets, manholes, hydrants and site symbols. Trace utilities and routes; measure paving and grading-zone areas.

Bring these documents

Site plans, survey references, utility schedules and elevation surfaces where the scope requires them.

Mistake to catch

Mixing coordinate systems or units, or deriving earthwork volume from a flat area without an elevation basis.

Run this demo test

Check a known route dimension and its coordinate system. For a volume request, show the surfaces and calculation assumptions or record the missing inputs.

Building automation

Identify sensors, controllers and panels. Trace networks and reconcile point names, equipment references and controller IDs.

Bring these documents

Controls plans, points lists, sequences and network schematics.

Mistake to catch

Treating points-list rows as physical devices. A designer can assign several points to one controller or define a software point.

Run this demo test

Select a controller with physical and software points. Ask for separate device and point counts, with references to the sequence requirements and unresolved scope.
