Egress requirements in the Building Code
Egress requirements in the Building Code
Provide a minimum of two exits from each
floor separated by a travel distance equal to not less than 1/2 of the length
of the maximum overall diagonal dimension of the floor to be served.
What does it mean?
Let's understand the intent of the code.
If the code would only ask the architect
to provide two exits without saying anything about how far apart the two exists
need to be, the designer can--theoretically--provide two exits, side by side,
on just one elevation of the building, and meet the code. So, there was a need to say that the two
exits need to be very far apart so that in case of an emergency people can run in
either direction. But then how far is
'very far'? Enter the diagonal. Measure the diagonal and then take half of
that measurement. Your two exits need to
be equal to or more than that number.
Say, the diagonal is 100 feet.
Then the exits should be anywhere between 50 and 100 ft--two exits only
49 ft. apart will not work.

What is a ‘draw’ in construction?
What is a ‘draw’ in
construction?
Online dictionaries seem to be
far behind in including terminologies specific to the construction
industry. This post is being written to help
the person looking for the meaning of ‘Draw’ or ‘Draw Meeting’.
Draw
Refers to the amount a
contractor is asking for payment from the allocated budget of a construction
project—think of it as money being drawn out of a pool.
Draw can also be associated
with a cardinal number in a series of payments to the contractor e.g., ‘first
draw’, ‘second draw’.
Draw meeting
Refers to a meeting of the
contractor and other parties (mostly the architect and an owner’s
representative) to compare the ‘Draw amount’ or the ‘work completed’ amount
with the actual construction progress on site.
Documents
Draw documents include:
1.
Application and
Certificate for Payment. AIA G702, and
2.
Description of work
completed to date. AIA G703
