Reference notes on the standards behind each method, with jurisdiction and edition stated.
Costing and commercial control. 5 questions answered below, each with the arithmetic behind it and the limits of what the tool decides. Open the International Code Reference tool.
A construction code is a legal document that changes by jurisdiction, and a calculator that assumed one would be wrong almost everywhere. This reference exists to point at the right standard rather than to substitute for it, and to make clear which questions are answered locally. It covers the areas that come up in estimating: material standards, structural design bases, electrical and plumbing requirements, fire, thermal and drainage. Each entry names the standard and the jurisdiction it applies to, with the caveat that the edition in force is a local matter. What the reference will not do is tell you a wall is compliant, because compliance is a judgement about a specific design against a specific edition.
A query about the minimum thickness of a structural slab returns the design standards that govern it and the note that the edition in force depends on where the building is. The reference does not return a thickness, because the thickness comes from a design against that standard. What it does is make sure the designer is looking at the right document rather than at a figure from a calculator that assumed a code the project is not built under. That single check prevents a class of error that no amount of arithmetic care can catch.
References to the standards relevant to each discipline, with the jurisdiction they apply to and the body that publishes them. It is a map of where the requirements live rather than a copy of them. It also states where a design decision depends on a local code, which is often the most useful thing it does.
No, and it does not attempt to. Standards are copyrighted, revised on their own cycles and adopted by jurisdictions at different times, so reproducing one would produce a document that is out of date somewhere and unenforceable everywhere. The reference points you at the source, which is where the current requirements actually are.
Because a requirement that is mandatory in one country is guidance in another and unknown in a third, and a quantity tool that ignored that would be making a legal claim by accident. Naming the jurisdiction for each reference keeps that visible, so a design decision made in one market is not imported into another along with its assumptions. That is a common and expensive mistake on projects where the designer, the contractor and the building are in three different places.
No. A calculator checks arithmetic and a code checks a design, and the two are different claims. The reference tells you which standard governs a question. Whether a particular design complies is a judgement that requires the standard's text, the design, and someone qualified to read both. The reference's contribution is to get the right text in front of the right person.
It is as current as the reference list it holds, and each entry names the body that publishes the standard so the edition in force can be confirmed there. Standards change, and a jurisdiction may adopt an edition years after publication, so the confirmation is a local act rather than something a page can do for you.
