    Street parking restriction design

    This is a petty/personal issue, but it has me rather incensed and looking to present a logical solution to my Council. My two-block long street is 28ft wide terminating at another residential access on one end and residential collector on the other, sidewalk on one side only. Recently, it was...

    HVAC sizing for ICF block house

    I'm looking for some reference documentation to point a client towards for sizing an HVAC system. The situation is they built a house with manufactured ICF blocks, two story, 2500 TLA. In this area, residential utilities are simply sized/installed per code (no engineering design required)...

    HUD PFGMH dry stacked piers

    This is a rehash of previous threads in '08 & '10 regarding dry-stacked piers for manufactured housing installation. Specifically, is there any current, definitive recognition by HUD for using dry-stacked CMU piers over frost depth footings with a proprietary anchoring system (Tiedown...

    USACE Wetlands determination - drained lake ~1980s

    Appreciate the response GeoEnvGuy. I'm just going to recommend he doesn't "fight" it and remove the fill as the USACE called out.

    USACE Wetlands determination - drained lake ~1980s

    On a project, I had a client ask my opinion or help on a issue he is having with the Army Corps, and his fill in a former lake bed. Briefly, a private lake was constructed in the ~40s for a small development around the perimeter (estimating, very few historical records). Nothing really...

    Replacement for Strucalc

    To all, thank you for the replies. Seems like most of the same software I've been reading about with a few packages I hadn't heard about before. I'll get some trial installs going and unfortunately will probably be looking at the subscription programs as the seat purchase ones above are far...

    Replacement for Strucalc

    There are a couple of older threads regarding replacing strucalc software or comparing it to other options for quick straightforward residential structural analysis. A local jurisdiction that I occasionally work in has jumped to 2018 with plans to move to 2021 next year. My latest version of...

    "seat" for overhead door, associated installation

    @ornerynorsk, it gets taken out after slab starts to set, like temp forms on a stair riser. To leave a blocked out area at the door. Darn, forgot to get a better picture. Though, this is leading me to agree with my conclusion that there isn't a requirement for it, and maybe its even a...

    "seat" for overhead door, associated installation

    MotorCity, it is basically a 2x8 laid flat, blocked out at the overhead door location creating a small lip between the driveway and interior garage slab. I attached a picture of a small corner. I'll snap a better one over lunch...

    "seat" for overhead door, associated installation

    Is there any requirement in code for an overhead door seat. My understanding has always been that this is optional based on the Homeowners needs. I personally prefer mine to have no seat as I have a lot of hard-tired junk that I move in and out frequently. The seat on one of the company shop...

    Spoke with a potential client today. Am seeking some suggestions for direction to proceed. Situation. Standard rectangular house, 8' foundation wall on 8"x16" footing. Owner wants to significantly regrade the property and create a walkout area on the rear foundation wall. This area has an...

    Workman's comp insurance

    Ron, the opt out option was my understanding as well. I spoke with my State Workman's Comp division, and they pointed me to an exemption form, but it specifically dealt only with construction trades (which I would think more critical to have workman's comp). My NCCI code would probably be 8602...

    Workman's comp insurance

    Just a quick question for anyone else that is the sole Owner/employee of an Engineering firm. My City recently asked for a workman's comp certificate in order to renew my business license. I was always under the impression that the Owner (or an officer or family member) were not required to...

    Concrete slab against untreated rim in garage - already installed

    A contractor called on a project I am not involved with, but I will help if I can. On a house construction project, the Owner wanted the garage slab poured for zero entry to the house after plans had been submitted and approved with conventional construction. Foundation installer set up an...

    Detention pond volume

    Picking up a project to help an Architect we've worked with before. The project dragged out long enough that the original Engineer (also a small shop) picked up a big project and now can't set aside the time to complete. I'm completing a grading plan for the lot and trying to layout a...

    FSD with concrete slab simply supported on bottom flange of beam

    I'm looking for design references for the following situation: Client needs to maximize height below a suspended slab in a residential garage. Is it possible to support the slab on the bottom flange of the beam? The beam would be the same depth as the slab and decking, and would be exposed at...

    Design Reference for Low Pressure Pipe Onsite Wastewater Treatment System

    Folks, thank you for the references. Years ago a local County had a publication very similar to the Orenco download, but nobody there recalls it or has been able to find it. Tkall, during this process I've been considering how useful it would be to setup a spreadsheet program to design one of...

    Design Reference for Low Pressure Pipe Onsite Wastewater Treatment System

    Davefitz, thank you for the information on Red Vector. I have not used that site before, and will look through it. In the meantime, could you give me the title of your Design Manual (ISBN)? E-one has sections for Technical reprints, maybe I will be able to track it down through their website...

    Design Reference for Low Pressure Pipe Onsite Wastewater Treatment System

    BIMR, thanks for the reply. I reviewed the information, but it does not contain what we sought. Here are the system characteristics: 1050 lf ~ 2" sch 40 PVC dosing tank to field 3000 sq. ft. field (450 GPD per local ordinance, 0.15 loading rate) Field is 10 lines, 5' O.C., 70 lf w/ # of...

    Design Reference for Low Pressure Pipe Onsite Wastewater Treatment System

    I am looking for any reference material on design of a low pressure pipe onsite wastewater treatment system. There is plenty of information available on the minimum standards, but I am having no luck finding hydraulic design information in relation to appropriately sizing the pump. We have...
