RHCES Estimator turns hand-drawn quantity sheets into a live 3D model. Define beams, columns, slabs, footings, walls, stairs, and trusses; watch concrete volumes, formwork areas, rebar weights, and cost estimates update in real time. Export to PDF or Excel with a full bar-bending schedule included.
Beams, columns, slabs, footings — each has a dedicated editor with live 3D, calculations tab, and quantities table.
Nine element types, real-time 3D, ACI 318 / NSCP rebar math, and one-click PDF/Excel reports.
Beams, columns, slabs, footings, combined footings, walls, stairs, assemblies, and steel trusses — each with full geometry, rebar, and cost parameters.
HelixToolkit-powered viewport with plan, elevation, and isometric modes. Rotate, zoom, and pan as you edit; rebar cages update instantly.
Auto-generated BBS with bar mark, shape, diameter, cut length, count, and weight per bar size. Exported to both Excel (BBS sheet) and PDF appendix.
Concrete (m³), formwork (m²), rebar (kg) per element and project-wide. Splice and cutoff wastage tracked separately so you see honest totals.
Editable unit costs for concrete, rebar, formwork, structural steel, plus labor / overhead / contingency. Grand total updates with every edit.
One-click QuestPDF report — project info, summary tables, per-element breakdowns, BBS, and 3D screenshots. Excel mirror via ClosedXML.
Auto-save every 2 minutes, 50-step undo/redo, recovery prompt on next launch if the previous session ended uncleanly.
Two columns per footing with independent pedestal, dowel, and tie inputs; per-face dowel counts; "Mirror Col 1" one-click copy.
Single-/double-angle, channel, SHS, CHS members with Howe/Hip/Scissor topologies, gusset plates, and a dedicated Steel Schedule export.
v3.16.0 brings the whole app into one cohesive blue theme - a blue title bar, a solid-blue active toolbar with the draw and select tools highlighting in blue with white labels, blue primary buttons, and soft-shadow white cards throughout. The active tool is always lit, so you can see at a glance what you are drawing or selecting.
Combined footings now sit like isolated footings - centred on their placement in plan and anchored by their top in elevation, so the supported columns rest on top of the footing instead of passing through it, whatever the footing depth. New Match Properties (right-click an element while other elements of the same type are selected) copies its full definition - size, rebar, hooks and materials - onto the others, each as an independent copy that keeps its own name and position. This release is UI and 3D-visualization only - every quantity, BBS line, cost roll-up and the .rhces file format is unchanged.

Founder · RHCEPEDA Engineering Services
RHCES Estimator is built and maintained by a practicing structural engineer. Every feature — from the combined-footing per-face dowel counts to the bar-bending schedule's per-bar-size grouping — came from a real project quantity takeoff. The tool ships with the same conventions used in Philippine construction (NSCP / ACI 318), and the rebar math matches what you'd compute by hand. If a calculation looks off, please flag it and we'll trace it back to the source line in the .rhces file.
30 days, starting from your first trial registration. Full access to every feature — beams, columns, slabs, footings, combined footings, walls, stairs, trusses, 3D viewport, BBS, PDF/Excel export. No credit card required to start.
The app continues to launch but switches to a read-only state until you
activate a subscription license. Your saved .rhces projects
stay on disk and remain openable; you just can't edit or export until the

License or from your account on rhces.com.
The standard license is for one active machine at a time. You can deactivate the current machine from the Trial / License dialog and then activate on a different one. This is designed to handle the case where you replace a laptop without needing support intervention.
Yes — every release is gated by a parity harness against a reference 2-storey fixture. The contract is ±0.5% per element, ±0.1% on project totals, and exact match on BBS row count and cut-length sum per bar size. v3.3.x has shipped 6 patches and quantities are unchanged from v3.1.0 except where the change was intentional (e.g. combined footings with per-face dowels).
The license cache stays valid for a 3-day grace period after the last successful online check. Open the app once on Wi-Fi to warm the cache and it'll keep working on a job site without internet for up to 72 hours before prompting you to reconnect.
.rhces for save / load (indented JSON), .pdf for the full report (QuestPDF — landscape pages for BBS & assembly views), and .xlsx for spreadsheet workflow (ClosedXML — separate sheets for project summary, per-element quantities, BBS, and steel schedule).
