Editorial policy

Who writes this

Articles are written by the Constropedia editorial team at Binary and Bricks Pvt. Ltd. and reviewed by a civil engineer before publication. Every article carries an "Updated" date reflecting its last substantive revision, not a cosmetic edit.

Standards we work to

We lead with Indian Standards — principally IS 456 for concrete, IS 2502 for bar bending and fixing, IS 1786 for reinforcement bars, IS 1077 for bricks and IS 1200 for measurement — because that is what most of our readers specify against.

Where another code family differs materially, we say so and give the equivalent: ACI and the IRC for North America, BS EN and NRM2 for the UK. Where a figure is common site practice rather than a code requirement — a 50d lap, a 1:1:2 "M25" mix — we label it as convention, because the distinction matters when a specification is being argued.

How worked examples are checked

Every formula in an article is applied to a numbered worked example with real dimensions, and every example is recalculated independently before publication. Where an article has a matching free calculator, the calculator is tested against the article's own worked example, so the two can never quietly diverge.

Numbers are presented in both metric and imperial where that is practical, and we state the assumed densities and conversion factors rather than burying them.

What we will not publish

• Invented statistics, ratings or download figures. Where we quote a number about our own products, it comes from our own records or our own store listings.
• Structural design advice that replaces an engineer. Our guides explain method and quantity; they do not size members or specify reinforcement for your building.
• Sponsored articles, paid placements or third-party affiliate links.

How we handle app promotion

Constropedia is published by a company that sells construction apps, and we are not coy about it. Articles link to our apps and to our free browser calculators. Two rules govern that:

1. The article has to stand on its own. If you never tap a promo card, you should still leave with a method you can use on site.
2. The free tool comes first where the free tool is sufficient. We point to an app when the app genuinely does something the browser cannot — working offline, exporting a report, carrying a full shape library in your pocket.

Every commercial link on this site points to a product we make. There are no third-party affiliate arrangements.

Corrections

If we get something wrong, we fix the article and update its date. Substantive corrections — a changed formula, a revised figure, a reversed conclusion — are noted in the article itself rather than made silently.

Report an error through our contact form with the page URL and the specific statement. We would rather be corrected than be quietly wrong.

Use of AI

We use software tools in drafting and checking, as most publishers now do. Every article is reviewed by a person before it is published, and the editorial team is accountable for what appears here regardless of how it was drafted. No article is published without human review.
