Work breakdown for frame structure quantities

A work breakdown structure (WBS) divides the whole quantity-calculation job into smaller, manageable work packages, each with a clear owner and output. For an RCC frame building I would plan it as follows.

Step 1: Understand the scope

Collect the architectural and structural drawings (plans, sections, column layout, beam and slab details, schedules), the specifications and the BOQ format.

Step 2: Break down into levels

Level 0  Frame building project
 |
 +-- 1 Substructure
 |    1.1 Earthwork   1.2 PCC/soling
 |    1.3 Footings    1.4 Columns to plinth
 |    1.5 Plinth beam 1.6 Backfill, DPC
 +-- 2 Superstructure (per floor)
 |    2.1 Columns  2.2 Beams  2.3 Slab
 |    2.4 Stair    2.5 Brick/block walls
 |    2.6 Lintel, sunshade, parapet
 +-- 3 Finishing
 |    plaster, floor, paint, doors, windows
 +-- 4 Services (water, sanitary, electrical)
 +-- 5 External works (boundary, drain, road)

Step 3: Define each work package

For every package: concrete, formwork and reinforcement are taken separately (m³, m², kg), with the drawing reference, the formula, and the check procedure.

Step 4: Assign and schedule

Distribute the packages among the team members, set deadlines in the order of construction, and use a common quantity sheet format.

Step 5: Check and compile

Cross-check totals (for example concrete from columns + beams + slabs against the structural volume), consolidate into the BOQ, and prepare the abstract of cost.
