Designing 4 story building/residence, in a multifamily zone, residential zoning codes quite restrictive, several regulations impinge on the design. Attached 2 unit multi family is one of the units. Unit 1 is on floor 1, 2 and 3. Necessarily Unit 2 is on Floor 4.

- We'd like to model the foundations for a 30 home hillside residential development in a software tool before getting into all the calculations and so on.
- Each of the 30 homes is at a different elevation, many are directly off a new road that goes up the hillside, with a switchback
- The...
We have a Two storey residential structure. Client mandates steel frame. Modular in nature - frames butted up one to the other, creating redundancy. Not a public building etc.
Rather than design specific connector (which is quite intricate) it has been suggested to use Hollo bolts. The...
We're necessarily importing some components (all tested, QAed, reports) from outside the country for a project (necessarily per client).
There is a specification for bolts - "all bolts to be hand tight. no preloading is prescribed". Is this currently permitted per ASCE and others, for...
Other than freelancer.com, or better upwork.com, does anybody know other websites where one can pick up engineering projects? I realize that this way is not every engineer's 'thing' by any stretch of the imagination. Nevertheless, suggestions welcome. I haven't found a good one yet. It...

Thank you much for your input. We ended up doing the attached - for Planning Permit purposes.
A combination of concrete v ditch, HDPE picking up through inlets from the v ditch, and an energy dissipater before crossing the new road. The...
Junior engineering designer here working on a storm drains for residential project in Bay Area California, with very few other similar recent projects generally undertaken by any entity on steep slopes. For storm drainage, I m specifying Concrete V drain, with catch basins every so often down...
Would anybody we prepared to stab a guess what standard sizes these I beams W Beams and steel tubes are? They are certainly Chinese steel. Guesses appreciated.

My task as designer and specifier is to write up a brief for a readily built steel frame, to give to a structural engineer. The back ground - the cut steel and components will be shipped to ... the jungle. Yes. A team of untrained military personnel will assemble the frame (same frame...
THANK YOU all for the input, wide ranging. My hope has been confirmed, that this is an acceptable way of making i beams h beams. Agreed, the mill coming on line may be a risk - I sense it will be a timing one where there will possibly be delays. In the meantime we will buy steel from our...

True blood, David, thank you.
Attached, roughest of sketches. The corners David somehow like your stream trunk corners. As you say with bolt holes, to get the bolts in, once the HSS posts, and horizontal I beams were in. The insert for the I beam needs some thought beyond my sketch. The...
David (and Bob)
Thanks much. Yes, this is a frame with no sensitivity to smoothness of finish - it will be covered by sheathing and siding Please see attached - a simplified design - some of the prior beams particularly the thin ones were/are temporary to provide rigidity only for shipping...
Hi David, Thanks much for the informative response. Attached is one frame that we must make from molds. It's structural for construction. ( Some of the cross pieces could be added later, I m sure you get the idea). As you say there are corner molds. There could be a mold for the...
Hi jayrod12 Yes, I am thinking of California in particular. Very cautious codes have been created here, we seem to have a lot of lawyers. Example - sprinklers in all new residential (yes) Solar panels in all new residential (unless absolutely impossible) So, I m hoping somebody...
Searched through the first hundreds pages of California Residential code - is it now necessary to fire proof spray on fire protection for structural steel frame in California residential or can I leave design such that visible beams will look more attractive?
We need to have a mould for a frame (8' x 6' x 35'), with equivalent W6x 12, but to pour into the mould. This will be a repetitive job, making many of the same frame, we expect that to remove the mould it will (will have to be) thrown away. Clearly the 8 corners will be the most complex...
