Prestressing Cost Comparison

Compare preliminary RC and PT options using steel quantities, direct costs and cost per square metre before detailed drawings are available.

Basic Parameters

Project name

Span arrangement (m)

Total beam length (m)

Beam spacing (m)

Number of beams

Analysis area (m²)

Beam width (mm)

RC beam depth (mm)

Optimised PT beam depth (mm)

Rebar all-in rate (CNY/t)

Strand all-in rate (CNY/t)

Preliminary comparisons use all-in rebar and strand rates. Anchorages, ducts, stressing, grouting and concrete are not priced separately.

Each row: name | number of bars | diameter (mm) | length per bar (m) | unit mass (kg/m). If blank, unit mass is calculated as d² × 0.00617.

Include bottom bars, support bars and additional reinforcement retained in the PT option.

Each row: name | tendon count | strands per tendon | tendon length (m) | unit mass (kg/m). For 15.2 mm strand, 1.101 kg/m may be used.
