Description
Structural design for building engineers, to BS 8110-1:1997. Run a whole-building load takedown, design every column in a grid, and get a bar bending schedule and drawings — from your phone, on site or in the office.
Built for Nigerian practice, by a COREN civil engineer.
WHAT IT DESIGNS
• Building takedown — accumulates Gk and Qk from roof through floors, walls and self weights, then designs the typical slab, beam, ground column and footing in one pass
• Column grid — every column in a bays × bays grid, classified corner, edge and interior with exact tributary areas, with a plan map of the families
• Slabs — one-way and two-way solid slabs, Table 3.13 and 3.14 coefficients, flexure, shear and deflection
• Beams — singly and doubly reinforced, shear links, span/depth deflection check
• Columns — short columns by equations 38 and 39, slender columns to clause 3.8.3, biaxial bending to 3.8.4.5
• Foundations — pad footings, strip footings under blockwork, and solid rafts
• Stairs, lintels
• Wind and stability — storey shears, base shear, overturning, sway against h/500 and the P-delta stability index
EVERY RESULT IS A CALC SHEET
Formula, substituted values, and a PASS or FAIL on each check — not just an answer. Designs that fail say what to change. Every sheet carries its scope and limitations.
BAR BENDING SCHEDULES AND QUANTITIES
Schedules to BS 8666 with shape codes, cutting lengths and nominal masses. Bills of quantities in concrete, steel, formwork and excavation, priced with your own naira rates.
DRAWINGS
Foundation layout general arrangement and a detail sheet per member, exported as PDF or DXF for your CAD.
PROJECTS AND REPORTS
Group designs into client jobs and export a branded PDF report with your practice details and COREN number. Work is stored on your phone, with an optional backup to your account.
HOW TALL IT GOES
Gravity-only designs stop at four storeys. With wind design, eight — braced walls, a core, or a moment frame. The app tells you which and why, rather than quietly designing something it should not.
WHAT IT WILL NOT DO
A PASS means the design checks out for the loads you entered, not that a building is safe to build. There is no seismic design, no piled foundation, and settlement is not calculated. Bar bending lengths use simplified anchorage and lap assumptions stated on each sheet. You are the reviewing engineer, and every output says so.
FREE AND PAID
Single members — slab, beam, column, footing, strip footing, stair, lintel, raft and wind — are free, however many you run. A credit unlocks one project: a whole-building takedown or a column grid. Revising that project, re-running it and re-exporting it are free forever. An unpaid run still shows whether the building passes and every warning with it, so finding out that a design fails costs nothing.
