reinforcement quantity take-off using ReoMark

A practical walkthrough showing how structural engineers can create digital reinforcement markups, establish reliable quantities at preliminary design, optimise reinforcement tonnage, and maintain cost and sustainability targets as the project progresses into detailed design.

Project overview

Quantity-aware structural engineering

ReoMark connects reinforcement markups, quantity take-offs, optimisation, cost awareness and embodied-carbon assessment in one visible workflow.

What this tutorial demonstrates

ReoMark provides a structured digital environment for preparing reinforcement markups from the structural engineer to the production and drafting team. Reinforcement is modelled directly over the floor plan, allowing bottom, top, integrity, additional and shear reinforcement to remain clear and coordinated.

The same model produces a reinforcement quantity take-off. This gives the engineer early visibility of tonnage and makes it possible to compare alternative bar diameters and spacings, identify reinforcement-heavy areas and improve the efficiency of the design before documentation is complete.

The quantities can then support project cost planning and sustainability assessment through RateKALC and GreenKALC. The objective is not simply to minimise steel, but to establish realistic quantities early and maintain them as the architectural and structural design develops.

Learning outcomes

  • Understand why preliminary reinforcement quantities affect feasibility and cost plans.
  • Create clear digital reinforcement markups for drafting and production teams.
  • Generate reinforcement quantities directly from the marked-up floor plan.
  • Review reinforcement by layer, bar diameter and reinforcement type.
  • Compare alternative bar sizes and spacings to optimise tonnage.
  • Relate reinforcement and concrete quantities to cost and embodied carbon.
  • Maintain quantity targets from preliminary design through detailed documentation.

Engineering perspective

Establish the quantity early, then protect it

Preliminary structural quantities become commitments within cost plans and sustainability targets. They must remain visible as the project changes.

During the Development Approval stage, the structural engineer is not only preparing a structurally adequate scheme. The selected column grid, lateral system, slab thickness, transfer structure and basement arrangement establish the project's initial concrete and reinforcement quantities.

Those quantities influence feasibility, construction cost and sustainability targets. As the design progresses, architectural layouts, services coordination and compliance requirements continue to change. Good engineering accommodates those changes while maintaining or improving the structural quantities established at the earlier stage.

ReoMark makes this process measurable. Instead of relying on intuition alone, the engineer can compare the quantity effect of design decisions and maintain a clear record from preliminary design through to detailed documentation.

Engineering perspective
Reinforcement quantity should be treated as a design parameter, not merely as an output produced after the design is complete.

ReoMark keeps the reinforcement layout, quantities and design decisions visible. This helps the structural engineer communicate clearly with the production team, test alternatives and make commercially and environmentally informed decisions without hiding the engineering judgement required at every stage.
