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.
California Fire Code has...
- 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...
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...

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...
I am considering buying land in El Sobrante CA, ranging from steep slope to gentle slope on the same land. This is 12 miles west of Martinez CA and 4 miles north east of Richmond.
For single family home development.
The soils are Los OSOS dull brown surface soils 7 – 10 in thick (and...
I am a designer working in conjunction with my engineer (out of State, specializing in modular steel homes) I' ve designed a 3 story less than 60' long, single family. The home will be in structural steel, with lateral bracing. We ll install the same model home several times. For most all...
As no doubt members of this forum know better than I, designing and making calculations for pier and caisson based foundations in southern California is quite the exercise. For us, it is bounded by the City of Los Angeles codes, that require a geotechnical report, and then calculations for the...
My building department has informed me that I have to have piers or piles, down 10' or so, gain a geotechnical and soils report, for the geotechnical engineer to recommend a reduced set back from the long steep slope, to complete an extension (or actually permit an extension) to a house in the...
I have two foundation walls 18" wide, running between 2' and 5' deep. City of Los Angeles has done their checklist thing requiring Geological and Soils Report required. Incorporate all recommendations into palns. Geo and Soils Eng to sign plans (oh, ok) - the engineer already signed them...
