    2021 IBC 704.3

    Yes, that sounds reasonable since the 4" slab has a one-hour rating. I'm not sure if I would have accepted it had the floor above not been rated. Thanks for your input.

    2021 IBC 704.3

    704.3 states that the primary structural beam must be individually encased to achieve a rating. How is this performed when a fluted deck is placed over the beam and filled with concrete? I know some folks will say the concrete slab provides a rating; however, this is not what the code states...

    Is clearance needed at the 2nd-floor columns

    Thanks for your replies. It is only supporting the roof. Therefore, I think we are good. PhamENG, your answer sounds good; however, in the construction world, most engineers do not like RFIs and take their time responding. Typically, two to three weeks is the timeframe, especially for projects...

    Is clearance needed at the 2nd-floor columns

    Where a column passes through a 2nd floor and 3rd floor concrete slab, should there be any clearance provided between the column and the slab? The drawing does not show anything; it just seems like you would not want the concrete to bond to the steel column. The first-floor slab on grade had...

    How to verify plumbness of a drilled hole

    Thanks for the replies. ANE91, I, too, am ACI certified, and I agree there are many things to look at; however, if you have ever inspected USACE projects, you will understand that if it's in the manufacturer's requirements, you will inspect for it or be removed from the job. HTURKAK, I guess...

    How to verify plumbness of a drilled hole

    Per the manufacturer's requirements for post-installed anchors, the 1/2" x5" drilled holes in concrete must be within 6 degrees of plumb. As a Special Inspector, I must verify a few hundred holes based on Chapter 17 of the IBC. Is there a device that I can quickly measure the accuracy of the...

    Puddle welds on roof metal decking

    I am performing observations of the metal decking before the insulation boards are installed, and the contractor performing the welds to the deck is burning a lot of holes through the deck, mostly the size of a dime except a few, maybe the size of a nickel. I typically don't see this many; it's...

    Open Garage Damp Location?

    Would the boxes for the surface-mounted receptacles in a 10-story open commercial garage need to be damp-proof? A hard rain may get some of the boxes at the perimeter wet, but a typical rainstorm would not reach them.

    Water in electrical boxes at garage

    I have an open garage, and where the electrical boxes are located to provide power to the exit lights during rain, water is visible from the boxes. The International Building Code doesn't require a barrier to be provided on the top garage floor, so I would like to know if anything in the NEC...

    Aggregate size in relationship to reinforcement clearance

    I have been searching for the aggregate gravel size in relation to reinforcement clearance. I remember reading once that the reinforcement clearance could not be less than 1.5 the aggregate size. In other words, if the aggregate was 1", the clearance had to be a minimum of 1 1/2". I thought this...

    Concrete cover for Tilt Wall

    Per ACI 318-19, concrete cover for a wall exposed to weather is 1 1/2". Would not a tilt wall be considered exposed to weather? The engineer shows 3/4" coverage over the reinforcement.

    Access to Emergency VFD

    The access in front is not what I questioning. I don’t think you should have to climb over pipe to get to an emergency panel. I mean technically I could fail it based on the International Building Code which requires clear access for a path of egress.

    Access to Emergency VFD

    The electrical contractor installed a VFD exactly as shown on the drawings; however, the only access to it would be to climb over some pipe. It doesn't make sense that you would not have easier access to this variable frequency drive. Does code address access other than clearance to a panel? See...

    Ground Rod

    Very good advice. Thank you!

    Ground Rod

    I am often challenged by contractors when I ask for documentation of ground testing of their grounding system or in today's case, a ground rod. I show up for a final electrical inspection and find the ground rod has been installed however, I have no proof that 3' wasn't cut off (which has...

    Sprinkler requirements for attic

    The design professional used 13, and yes, the contractor wanted to fill it with non-com insulation. It's an R-2 4 stories he could have designed it to 13R but I am not sure why he used 13 other than he just wanted to use the more stringent. Fir blocking every 1000 sq. ft has been installed on...

    Sprinkler requirements for attic

    NFPA states sprinklers are not required in concealed spaces filled with noncombustible insulation. I have an 18" attic/concealed space above the top floor (flat roof), so can I say this is a concealed space? or is it the attic, which I may not be exempt?

    Does anyone know where I could find

    Does anyone know where I could find the backup to require the contractor to isolate the unistrut support from the mechanical duct resting on it? I have read this somewhere in a code or manufacturer product data. I am in the USA under the 2021 ICC codes. Section 603.12 kinda supports it but I was...

    Steel Gas Piping

    The 4” gas line is upstream from the meter and is installed overhead for a cooling tower. The code that I read did state the reason is so someone doesn’t mistaken it for something else. I just do not remember where this was called out

    Steel Gas Piping

    I read in a code but do not remember where but when two or more black steel pipes are installed at the same location, the gas pipe is required to be identified with yellow stripping or painted yellow. Does anyone know where this may have come from? I am in Texas, and I have looked in the 2021...
