When I arrived on site wood framing was being done by a crew of four men, working continuously throughout the day. They were working on the back side of the property, in the 16 unit building. Once the wall is built on the ground, three of them raise it up to be essentially level, then one other guy goes around with a nail gun attaching diagonal shoring at this point they go in with a level and make adjustments. They put the Tyvek on while they are building the wall on the floor to avoid having to get up on a ladder on the outside. This makes it a safer process and thus reduces liability and possibly cost.
While walking through the building I noticed that the shoring seemed both excessive and haphazard, which made me wonder if it was done correctly.
Another interesting aspect of the framing was that there was lots of extra blocking within the frame and metal straps attaching everything (sometimes even in excess). I was told that this was required because it is a LEED job. The metal straps are called hurricane straps and prevent against destruction due to high winds. I wondered if this was truly necessary in the area it was built, which doesnt tend to recieve excessively high winds.
One final thing I noticed was that even though the building was still exposed to the elements- some drywall had already been put in place. I was told this is weatherproof drywall that has to be put in place to ensure things like the floor joists were in their correct position. They used this sparingly, only where necessary.
