    Pipe Trench Flowable Fill Strength vs. TXMF Foundation Overexcavation Flowable Fill

    Hello Gents, I have an RFI from a contractor asking if he can use the same 150psi LSM electrical pipe trench flowable mix also below a large 36K transformer foundation over-excavation flowable fill. My concern is quality control of the mix and set time and well yes strength. The bearing...

    Cast In Place 37 ft deep Storm Water Wet Well Means and Methods

    Much appreciated, to all of the above. Again,...the contractor has asked for a cast in place design,...the water table below the bottom of the elevation of the well by about 10 feet. I suppose I could insist the shape be changed to a circular design and could design the well as a circular tank...

    Cast In Place 37 ft deep Storm Water Wet Well Means and Methods

    Tasked with designing a cast in place wet well structure. 37 feet deep, 12' by 17' Not sure the reasoning this was not sent out to pre-caster, but that ship has sailed and I was not part of the reasoning why I'm asked to design a cast in place option. Typically the pre-caster would form...

    LRFD Wind and Seismic Loads, W and E. Load Factors-"Global" Factors of Safety

    Thank you for your well formed and succinct response, Lomarandil! It's getting close to retirement for me, and at times like these, I feel I should already be. I will present my 'global' results in ASD as well for comparison for the plan checker's benefit, and for clarity to the owner (and...

    LRFD Wind and Seismic Loads, W and E. Load Factors-"Global" Factors of Safety

    Question Gents: Per ASCE the LRFD Load Combination have W and E loads included as factored Loads. Does this mean we can say that W abd E have inherent safety factor based upon it's load factor when using LRFD? And is the wind load factor equal to a demand FOS of 1/.6=1.67 and is the seismic load...

    Should I hire another person?

    Tough market in my opinion/agreeing with phamENG,....market pool of US grads not what it used to be. Everyone going into programing. New grads want nearly what I'm paying myself after all the bills are paid. Who am I kidding, they want more than I'm paying myself. But when growing,...that's...

    How much to charge?

    Sounds like you've found your bread and butter/niche XR250. If it works for you and family, this is a good thing. Careful then about taking only an occasional commercial job and underestimating time and effort and your worth. Not to mention, keeping up with code changes, losing some touch...

    Recommendations for Castellated Beam Design References and Software Design Programs

    Thank you all for the recommendations! I have the AISC Design Guide,...I look into the software recommended. Ideally I design one by hand first using the guide, then select and use a program. As my mentors used to say,...and maybe everyone agrees with regards to computer results,..."Garbage...

    How much to charge?

    RackaRoll, If you haven't done a PEMB foundation before, and I mean to the degree a seasoned third party CA plan checker may see fit, I would definitely feel you should consider whether you want this headache, especially if it may be a one timer. However, if you are willing to take one for the...

    Receipt of Payment

    I've been asked only occasionally, and thus I provide without question, and typically these are smaller project clients, and yes maybe with real estate sales involved. Otherwise assuming deposited check confirmation serves as receipt/transaction for both parties. I suppose if we honored...

    Who Approves Welding Certifications These Days? The EOR or Special Inspector

    Hey phamENG, Yes, this would be in California, where special inspection are required for just about everything under the sun. They/Special Inspectors are 'definitely' independent third parties as a requirement. So, since special inspection are part of the project requirements, would you, as the...

    Who Approves Welding Certifications These Days? The EOR or Special Inspector

    Hello All, Can anyone tell me what your policy is toward "approving"/reviewing welding certs. Do we/EOR's still do this when it's listed on the Special Inspection form as part of Special Inspections and they (Special Inspection Company) include this service within their scope and fees? Thanks...

    Connection between hollow section and channel beam

    And with regards to Welds: Basic premise for hand solution, SRSS about all three axis considering shear, moment, torsion divided by respective resisting normal and polar moments of inertia. If you eliminate the eccentricity of the vertical force as recommended in all suggested connection...
