I'm am modeling a bioretention planter that consists of a soil layer with a gravel storage bed beneath it (please see the attached image):
Layer 1 - soil mix, 40% voids, infiltration rate = 1.5 in/hr
Layer 2 - gravel storage bed, 33% voids
Subgrade - Native soil, infiltration rate = 3 in/hr

I have similar questions to the one asked in the thread listed below. Unfortunately there were no replies - I was wondering if anyone has experience with Woodworks and can provide some guidance on this or point me to another thread that discussed a similar topic.

Looking for some advice on obtaining documentation for engineered trusses. I was contracted to draw up plans for a residence that was built over ten years ago. Part of the residence was constructed beyond what was originally permitted and the client needs to get things up-to-date with the...
Hi,
I am wondering what is the best way to model this situation:
I have a roadside ditch which discharges into a culvert. Midway along the culvert, the slope changes from 0.5% to 1.5%. The culvert then discharges to another ditch. Should I model the culvert as two separate culverts in series?
I've been asked to look at a residential truss repair. The truss spans about 20 ft. The contractor has replaced the damaged members of the truss and is proposing using 12"x12" OSB gusset plates where the members connect. At one connection where the web connects to the bottom chord, the bottom...
Hi -
I've been asked for advice on the "reinforcing" required for a residential garage. The largest loading it will see is a Chevy truck.
The garage floor will be a 4" slab on grade on top of a 4" crushed rock base. The garage will be heated - so between the slab and base will be a 2"...
I'm designing an interior staircase for an existing building with the stringers spanning about about 13' (horizontal distance). I have to put in an intermediate support for the stringers in order to show them good. My plan is to use a 2x4 support wall in the middle of the staircase. I was...
I have a client that is proposing to build a garage with a wood floor system. The county is requiring that the flooring be non-combustible. The contractor would like to meet that requirement by using 1/2" cement board on top of 1-1/8" T&G plywood (the framing beneath is more than adequate)...
I've been asked to design the dry floodproofing measures for a non-residential pole building with 29 gauge metal siding. The owner does not want to elevate the building above the flood elevation, hence the floodproofing.
As I understand it, dry floodproofing the building would involve:
1)...
I'm designing a shop building which will have a radiant heated slab on grade. I've attached a jpeg which shows the foundation configuration. I have a couple of questions:
1)I'm showing the insulation under the slab and around the perimeter. Someone told me that it's also required that the...
Hi,
I need some help with a design for a sign. It is a 4’x8’ sign, supported by pressure treated wood posts. Please see the attached sketch. The jurisdiction requires that the sign and supporting structure be designed for a wind load of 30 psf. If I use tributary widths, I calculate a load...
Hi,
Question - is the attached detail for a raised floor with 1-1/8" T&G plywood a good way to detail for transferring the shear through the wall down to the mudsill? Specifically, I'm wondering about the nailing of the plywood to the rim joist (with the required edge nailing for the plywood)...
This is a pretty basic question about shearwall height. Let's say I have a 1-story house with 8' stud walls. The framed wall rests on the floor system, which consists of 2x12 joists (see attached .jpg file for a cross section).
For the shearwall height, do I use 8' or 8'+ depth of the floor?
Hi,
Does anyone have a detail (or know where I can find one), for a 2x6 corner (wood frame building)? I have one holdown (e.g. a Simpson HTT16) at the front of the building, and I want to tie the corner together so I can use one holdown for each direction. I've attached a sketch.
Thanks.

Hi,
I've got a question about minimum spacing requirements between shearwalls. My client has a 48'x40' building - he has to have it engineered since the wall height is greater than 10 ft. Right now, his plans have an interior shear wall line in the middle of the building (I believe this was to...
Hi,
I have a question about specifying the location of a retaining wall on a set of plans.... when locating the wall on the site plan, would it be acceptable to locate the beginning of the wall by specifying the wall's station and offset based on an adjacent road's centerline? Or is there a...
Hi,
Just wondering if anyone out there can give me an idea of how you structure your design fees for retaining wall designs (e.g. per sq ft, flat fee, per hour, etc.)
Thanks for your input.
Hi,
I was wondering if I could get a quick opinion on the detail shown in the attached jpg. It's the connection to a concrete footing for the tension member of an x-brace. The steel rod is bent approximately 11° and welded to a steel plate that is attached to a concrete footing with wedge...
I'm using a StormTech chamber system for a stormwater detention system. My outlet pipe is connected at a chamber end cap. The question I have is, what is the best way to model the outlet in HydroCAD?
