Subject: Design gen. Подскажите, пожалуйста, что может означать словосочетание f+g design в следующем предложении: Total manhours available to all civil works is 10%, 2% of which is slabs all awaiting a f+g design for conduit. Данное словосочетание выдержка из переписки и встречается один раз.

| а что строят? |
| м.б. проект СОПГ (системы обнаружения пламени и газа) |

Вот пишут про асфальт (думаю, у вас может быть похожее что-то): Mix types designated by letters (e.g., “E”, “F”, and “G”) and other obsolete types are no longer valid designs, and the ingredients and properties of these old designs may have changed in critical ways. Current GDOT mix types are designated by their nominal maximum particle size – 4.75, 9.5, 12.5, 19, and 25 mm. An approved mix design of a given type is assigned an alpha-numeric code indicating the sources of the aggregate, the mix type and size, and the certified commercial lab which authored it. For example, a mix with the identifier 16-12.5SP-10-6 would be a 12.5mm mix consisting of aggregate from source number 16, designed by certified laboratory number 6. The 10 is a serial number to distinguish the design from others like it. The unique identifier helps to ensure that the mixture specified is the one laid down and that it is tested according to the correct criteria. http://www.dot.ga.gov/doingbusiness/Materials/Documents/GeorgiaasphaltpavementresurfacingguideMay06.pdf |
| может означать "расчет" (плит) |
| Хотя наверное AsIs прав, да. Fire and Gas? |
| Посмотрите еще Types F & G or superplacticizers |
|
это про mixtures опять: ASTM C 494, Types F & G or superplacticizers are a special class of water reducers for very low water to cement ratios with slump ranges of 6 to 10 in. (150 - 255 mm) to produce very flowable concrete. HRWR’s are classified according to their water content reduction capacity which can range from 12% to as much as 40%. http://www.inti.gob.ar/cirsoc/pdf/estructuras_hormigon/1_FloorDesignGuide.pdf |
| Думаю, раз conduit, то 2.08.2013 15:38 +1 |
| там по ссылке Concrete Floor Systems Design Guide, как бы со slabs то же сочетается. |
| Спасибо всем большое! я думаю, что СОПГ подходит, поскольку проект находится уже на таком этапе, когда идет подкючение КИП, электрики и т.д. |
