    Code Requirements of Exterior Hardescape Stairs

    So the international building codes obviously have a plethora of requirements for stairways, but these codes are specifically written for stairways within a structure, not outside of a structure. It seems like like stairways outside of a structure are somewhat ungoverned. Outside of ADA...

    Liability of Changing Residential Site Drainage

    On your typical 0.25 acre suburban single family housing properties, do any of you have a feel for the standard of care when one homeowner makes a change to the surface water flow in how it might affects a neighboring property? Is this codified or standardized anywhere or is it more of a state...

    Deicer Trucks on Parking Garages

    Does anyone have any good references that talk about proper winter maintenance practices on parking garages? Specifically regarding how to address the weight of deicer/plow trucks? I find that the weight of deicer trucks will typically exceed code loading, and I am curious as to how the code...

    Scanning Large Format Plans

    Due to COVID, a lot of print/scanner shops are shut down. Does anyone know of any alternatives to just taking photos of plan sheets? I would have thought by now there would be some good apps or scanner wands that could handle scanning full size construction sheets, but I'm not seeing anything...

    Groundwater Induced Basement Wall Failures - Defining Hydrostatic Failure

    Since it hasn't stopped raining for the past year on the east coast, I have been seeing a slew of CMU basement wall failures. I see a lot of engineers chalk up these types of failures to "hydrostatic pressure" induced from "the pressure of the water column acting on the face of the wall"...

    Flat Roof Perimeter Nailer Anchorage Design

    Has anyone here been involved in the design of wood nailer plates around the perimeter of a flat roof system? I'm curious if there's any design guides out there that might establish standard design assumptions.

    New Wood Joists in Existing Brick Pockets

    In old brick masonry construction, they often pocketed floor joists right into the masonry bearing walls (interior and exterior walls). When dealing with fire damage to these buildings, would you ever go back with new joists bearing in the existing masonry pockets, or would you come up with...

    f'm for masonry wall at wide flange bearing point

    I'm looking to verify the capacity of an existing bearing point where a wide flange is bearing on the edge of a CMU wall corner. Due to the way the wall is coursed and lack of bearing plate, there are several vertical head joints that I think would significantly reduce the capacity of the...

    Roof Truss Replacement - Matching the Profile of Adjacent Trusses

    If only a portion of residential roof gets damaged (lets keep it simple, say a simple gable roof), have you seen GC's able to order replacement trusses that match the profile of the existing trusses? I feel like any minor measurement error can be made up by the 2' truss spacing. Or do they...

    New Jersey seals on engineering reports

    For any of you who write engineering reports in NJ, how do you handle electronic transmittal's of your reports to your clients? NJ is still hung up on embossed seals and says you cant allow photocopy/scans of it, but almost all clients want electronic submittals. This means if you email a...

    Structural Design of Push Pier Systems

    I am researching the standard protocol for the design of residential push pier stabilization systems. If you have experience in this, how have you seen the process typically go? I.e., did the owner directly retain their own SE to come up with a design? Or does the foundation contractor retain...

    Private residential inspection - When to notify building official of unsafe structure

    In single family residential construction, if you (PE) are retained by the homeowner to inspect the home and find an unsafe condition, you obviously notify the homeowner of the building. However, are you obligated to notify the building official?

    Standard of Care of a Home Designer

    I have found that there's a whole industry out there of Home Designers. These are folks who are not licensed architects or engineers, but put together comprehensive design drawings for contractors to utilize. They seem to get around the professional license requirements by the disclaimer that...

    Exterior Terrace Structural Slab Profile

    In external terrace designs that utilize a topping slab over a membrane, over a structural slab, and with integrated dual tier drains (i.e., the drains that have a lower level of seepage holes), is everyone typically seeing requirements for the top of the structural slab to slope toward the...

    Discovery of Undersized Members

    If a structural element, say a wooden window header, is slightly undersized (say 5% overstress under design load) and nobody catches it; the building is constructed, CO approved; can a building inspector legally come back in (say 10 years later) and require the element to be upgraded? If so...

    Duty to Warn - who?

    My company does a lot of condition assessments of commercial and single-family residential and this question came up. When you discover a dangerous condition in an existing building/residence, as a PE, are you legally required to notify the owner, the building official, or both? Our current...

    Actual strength of a structure to resist wind-loads

    Say you have a residence that was constructed in 1995, and you want to accurately determine the wind-speed at which the residence would start to sustain structural damage. My thoughts are that you could not reliably do this by calculation using ASCE 7, primarily because of all of the additive...

    Permanent Bracing for Pre-manufactured Wooden Roof Trusses

    I'm looking at long-span (but under 60' span) pre-manufactured wooden scissor trusses each with a highly loaded 2x compression member (10kip+) that isn't attached to the roof sheathing...it flies across the attic space horizontally. BCSI B-3 gives prescriptive methods for installing permanent...

    IEBC Seminars

    Has anyone here participated in learning seminars and/or reference materials for the IEBC (Existing Building Code) you thought were worthwhile? A lot of people at my work seem to struggle (including me) with the intent of that code.

    Engineering inspection of buildings

    Does anyone know the particulars regarding licensing requirements for structural related inspections? Lets say in the midwest or east. In particular, can an EIT (or a PE from another state) conduct a structural inspection, report to a licensed PE/SE, and then submit a report that is co-signed...
