Finding the applicable standard for a specific test or construction practice is not always easy. Although still a little rough around the edges, and with a name that offends my delicate editor's sensibility, a new tool I’ve recently been introduced to can help. Created by engineer Kishore Kotha, Standerds guides the user to the applicable standard.
Designed in a tree structure, Standerds guides the use from a general topic to a specific action and provides the applicable subsection of a standard, which could save time digging through a table of contents. For example, if I click on Concrete Standards, some of the choices are Construction Standards, Design Standards, and Test Standards. Clicking on Construction Standards provides choices like Formwork Construction or Anchoring Installation. Formwork Construction then expands to seven choices, including Constructing/Erecting, which expands to three choices, including General Requirements. This then reveals that the provisions to review are ACI 301, Section 2.3.1 and ACI 318 Section 26.11.2. This sounds like a lot of navigating to get to this point but it is actually a very quick series of choices.
For some sections, such as Test Standards, clicking from Concrete, Mortar & Grout to Fluid-State Concrete to Rheology to Workability indicates that five different organizations have such a test standard. Clicking on the organization's name (ASTM, Dept. of Transportation, etc.) we find that the standards used to test for workability include ASTM C143, AASHTO TP 73, AASHTO T 345, CRD-C 5, USBR No. 4143, and CSA A23.2-5C.
Knowing that, though, you still have to find those standards on your own—at least for now. The organizations issuing those standards have not allowed Kotha to post their standards, but at least you have a head start.
