    Painting metal beam hangers with intumescent paint

    Woodworks has a paper on fire rating of mass timber. Fire rating of connections begins on page 13. https://www.woodworks.org/wp-content/uploads/Wood_Solution_Paper-Fire-Design-of-Mass-Timber-Members-WoodWorks-Apr-2019.pdf

    unistrut structure

    Where is the 5'-9" limit in the code? In ASCE-7, there are exemptions for equipment with operating weight less than 20 lbs and equipment with operating weight less than 400lbs and has a center of gravity less 4' AFF. I'm curious about the 5'-9" limit

    Are they being required to add a stud on the left side of the panel? If not, how are they supporting the panel?

    Is this a code compliant electrical installation?

    If you want to be picky: Assuming the screws are Tapcons in masonry, they don't appear to meet the screw's minimum spacing and edge requirements in ESR-1671. https://www.icc-es.org/wp-content/uploads/report-directory/ESR-1671.pdf

    Electrical to a kitchen island on a slab

    Mark K A conventional slab on grade is not in the scope of ACI 318. See ACI 318-14 section 1.4.7: "This codes does not apply to the design and construction of slabs-on-ground, unless the slab transmits vertical loads or lateral forces from other portions of the structure to the soil"

    Flowable Fill

    See 2018 IBC section 1904.2 for non-structural concrete. The minimum strength depends on exposure, but there is nothing less than 2500 psi.

    Question for the masses? Does a compression post have to be plumb?

    Builder Bob, If you are looking for a reliable reference rather than a code requirement. California DSA has an Interpretation of Regulation, IR 25-2 for lay-in ceilings. In section 2.3.e, it specifies the same 1H to 6V for compression posts. OSHPD's pre approved ceiling pre approved details for...

    Personnel safety beam in elevator shaft

    OSHA 1926 is a standard for construction industry. One the building is built, it does not apply.

    Using NM Cable (Romex) in Type I and II Construction

    I want to make sure I have this right. When NM is installed, the building can no longer be classified/permitted as a Type I. Any type fire-life-safety exceptions or area increase go out the window and the building is no longer type I construction.

    OSHA Question - I know wrong forum, but thought I would try

    A couple years ago, OSHA revised the Walking-Working Surface and Fall Protection requirements. For toeboards, try 1910.29(k). https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.29

    Seismic Ceiling grid suspension wires color coded

    Bay Window floor Area Calculations

    I really don't know. But, the City of Los Angles zoning code is online and I found the following: FLOOR AREA, RESIDENTIAL. (Amended by Ord. No. 184,802, Eff. 3/17/17.) The area in square feet confined within the exterior walls of a residential or non-residential Building on a Lot in an RA. ...

    Legislation to Eliminate Codes

    Conarb, I'd would prefer more high-density/high-rise development while maintaining open-spaces on public land for recreation and preservation. If there isn't enough high-density housing near transit centers for Google's engineers making 120k, more should be built. Open spaces around me increase...

    Storm-Prone States Are Relaxing Building Codes Instead of Making Them Tougher

    It's probably been 5 years since I saw a cost estimate with beam column connections as a separate line item for a small building. It was for Reduced Beam Section (RBS aka dog bone) connections and they were around $600 extra per connection. This didn't include testing and inspection fess paid by...

    Storm-Prone States Are Relaxing Building Codes Instead of Making Them Tougher

    Conarb, If it is like many change orders, the contractor charges $44,000 on a change order for something that costs the contractor $6,000. The amount of problems your engineers have with plan check makes me wonder if you need better engineers (or architects with commons sense).

    t-bar ceiling

    Yes. The requirement is in ASTM E580. Quote from 09 version below. If there is more recent version it has the same/similar For Seismic Design Category C: "4.4.3 Lighting fixtures weighing less than 10 lb [5 kg] shall have one, No. 12-gauge [2.70 mm] safety wire connected from the fixture housing...

    Factor of safety for field tested connection.

    Mark K, If needed, 1708 is the section for in-situ testing. If it is already installed and tested to failure, then, it is broken or badly distorted and no longer has any structural capacity. That is why I assumed pre-construction testing was more appropriate. The question is about a custom...

    Factor of safety for field tested connection.

    Probably better to use a safety factor of 2.5. See 2018 IBC Section 1709.3. Might be worth seeing if there are any ICC Acceptance criteria for joist hangers.
