    WFH/Remote Work Policies

    What are your firm's work-from-home/hybrid work policies? 1. How many days are you in-office vs WFH? Do you have core work hours within those WFH days say (9-4 or 9.30 - 4.30 etc.)? 2. How many weeks in a year is a person allowed to WFH? Is there a limit on the maximum number of consecutive...

    Development length schedules

    How do your firms show development length and lap splice schedules on construction drawings? Do you have the most conservative value calculated prior to the modifiers applied and spell out how the modifiers apply? For example, a #5 bar in 5000 psi concrete has a hook development length of 15"...

    Slab construction cycle times

    Looking to compile data for slab cycle times for post-tensioned slabs. Cycle time = ? days (Time between start of placing concrete on successive floors) Region in US or Country = xxx I am in Chicago and a 3-day cycle is routine for most high-rises.

    Experience Pyramid

    I am hoping this question is less controversial :) What does your firm's pyramid look like, either as a percentage or actual numbers? Experience Range >25 years = 15 - 25 years = 9 - 14 years = 4 - 8 years (ideally licensed) = 0 - 3 years = Also what is your typical ratio of engineering to...

    Interviewing candidates

    I am seeking feedback on how some of your firms conduct interviews for engineers in the 0-3 years of experience. More specifically, are your interviews strictly non-technical in nature or a combination of non-technical with a 10-20 question test to check their technical abilities. I would like...

    Wood framed buildings

    How do you all tackle simple wood framed buildings - like a normal Type V building? What's your workflow? Do you all use some software or a lot of in-house spreadsheets for various breakout tasks (gravity wall stud sizing, shear wall design etc.)?

    Concrete roof deck - freeze/thaw

    I have a project where a concrete roof "lid" which was supposed to be "interior" because of it receiving an architectural roof comprised on cold-formed trusses was left exposed during the winter and subjected to freeze-thaw. I haven't had this happen to me before and was wondering if there is...

    Vehicle crash barrier (W-beam or Thrie Beam)

    Does anyone have experience using a AASHTO highway style vehicle barrier in a building? Specifically the W beam or Thrie-beam style bent shapes made from light-gage steel bolted to wide-flange beams. Example...

    Conduits in slabs

    I am hoping someone can enlighten me on why ACI 318-14 and onwards, the requirements for conduit spacing (3 * diameter) and conduit diameter (less than 1/3 slab thickness) have been removed and replaced with a generic language. Refer to ACI 318-14 Sections 20.7 and 26.8.

    Wall Reinforcement Detailing - Poll

    In your respective firms, is there a standard for detailing reinforcement bars in a concrete shear wall in terms of which bar gets placed closest to the edge of concrete (vertical or horizontal) and why? CRSI's document on "Designer's responsibility for Rebar Design" seems to recommend vertical...

    Hoist Beam - Sway Bracing

    All - I have a electrical vault that is a few feet below street level and need to design a hoist beam to be able to carry 20,000 lb load. Are there any specific requirements as far as designing the hoist beam for torsion and sway bracing? The beam span is about 20' and it supported on a masonry...

    Slab on Grade (Edge)

    What's your typical detail for the following situations? 1. When a slab on grade terminates against an interior/exterior CMU or concrete wall? Do you have a thickened (turn down) edge or without it? Seems like it would be more work to first grade and compact and then excavate for a downturned...

    Horizontal Cold Joint - Footings

    All - are they are any issues with punching shear if a footing gets poured with a horizontal cold joint. For example, if there was a 4' thick footing that got poured in 2 lifts of 2' thickness. I have checked the interface shear and vertical reinforcement provided to cater to the horizontal...

    One Way Slab

    All: What is the standard detailing practice for top reinforcement perpendicular to the span of one way slabs when it hits a support. Example: 5" span spanning 20' between beams. Beams are in turn supported on edge girders. What is the top reinforcement required in the slab perpendicular to...

    Concrete Moment Frame Beam

    What's the typical detail in your firms on how far additional top bars at columns are extended? I have seen L/4 and L/3. Would appreciate if anyone had a typical detail that you could share. We are putting together a spreadsheet for moment frame beams based on ETABS outputs and wanted to add...

    ICC-ES Reports for Stud Rails

    All, Please be aware that the latest ICC-ESR Reports for punching shear reinforcement in the form of stud rails lowers the concrete shear capacity to 1.5 (f'c)^0.5 instead of 3 (f'c)^0.5. This includes even structures in SDC "C". ICC ESR 2494 (Decon), ICC ESR 2708 (Suncoast). We are not sure...

    Concrete slab edge - Masonry

    All, What is your company's standard detail of laterally bracing a non-load bearing masonry wall at the edge of a concrete slab? My current firm has a detail with a 1" gap and an angle connecting the inside face of the CMU to an embed in the slab soffit. My old firm had a detail with a #3 bar...

    Vehicle Barriers

    All, See article from Structure Magazine on vehicle barriers. A lot of firms have the standard detail at the concrete slab edge with moment transfer. I am interested in hearing opinions from other engineers on whether there is much merit to the deficiencies pointed out and how many of you have...

    Columns @ Roof

    What is the standard approach when detailing columns (which have unbalanced moments) and stop at the roof of a flat slab? For example, I have a 30' span next to a 18' span and the unbalanced moment is being resisted by the column. However, due to the slab being fairly thin, I cannot...

    Does tension tie force translate to horizontal shear at the top of column

    The title of my post says it all. Please see attached sketch.http://files.engineering.com/getfile.aspx?folder=6a859e11-b4a9-4c28-a49c-64fe43093c34&file=CCI10142014_00000.pdf
