I will take a stab at this with some additional caveats to your original question:
-Our market is in the Canadian Prairies so the building industry is VERY seasonal (winter temps into the -30 to -50 C range are not uncommon - though not the daily norm either)
-Fastest production - hands down building in spring/summer/fall is faster than winter (winter involves fewer daylight hours, the need to add/remove tarps each day to ensure snow does not fill the ICF cavity, working with gloves on, etc)
-HOWEVER, for the reasons listed previously, I would also argue that winter construction with ICF is LESS affected vs other building methods, including CIP concrete, steel, wood, etc. Also little/no heating/hording during concrete placement (saves time & money) and after concrete is placed and roof is installed, you now have an insulated envelope that can easily be heated for subsequent trades increasing overall production on the complete building.
Busiest months in our region for residential construction is April to October (may vary +/- based on weather). Commercial construction continues as projects are available to start and are not planned seasonally to the same extent (although the vast majority of the local ICF market is in residential construction). |
