How it works
From browsing to results in three simple steps.
Browse & Select
Choose from a growing library of structural and civil engineering calculations, organised by category and design standard.
Enter Your Values
Fill in the input form with your project parameters. Built-in validation guides you and flags any issues before you calculate.
Get Results & Export
Instantly see verified results with code references, diagrams, and charts — then export a structured PDF report.
Built for engineers
Everything you need to run accurate calculations, nothing you don't.
Trusted Results
Calculations verified against recognised design standards, with references clearly shown alongside every result.
Save & Organise
Save calculation inputs to named projects and return to them at any time from any device.
Export Reports
Generate and export a structured calculation report directly from the results page.
Design Code Coverage
Forms aligned to current EN Eurocode, BS, and other widely adopted engineering standards.
Works Everywhere
Runs in any modern browser — no installation, no licence keys, no operating system restrictions.
Growing Library
New structural and civil calculations added regularly, covering an ever-expanding range of engineering needs.
Recently Added
The latest calculation forms added to the library.
RC Beam
Calculation performs design of rectangular reinforced concrete beam to BS8110-1. The design is based on the limit state method and the beam is designed for bending and shear. Detailing and deflection checks are included.
Runoff
Estimates design surface water runoff for a catchment using four established UK empirical methods: Wallingford (HR Wallingford Procedure), IH124, ADAS, and FSSR6. An optional storage attenuation calculation is available for the Wallingford method.
Continuous Beam
Calculation performs the analysis of a continuous steel beam with multiple spans under various loading conditions. The Three-Moment Equation (Clapeyron) method is used to determine support reactions, from which shear, bending moment, slope and deflection are computed for the full beam.
Pile Group
Elastic analysis of a pile group under combined axial loads, shear forces, and bending moments from one or more columns. Resolves individual pile reactions and checks compression, tension, and shear capacities.
