If I understand you correctly, you don't need a business plan. (However, that 2nd link is great for all those posts that start with "I'm thinking of starting my own firm...")
What you need are examples of the answer to the following question: "I'm looking for an engineer to ___. Can you...
Our firm is looking to expand out of quickbooks as well. I assume you are small (less than 20 people). I've never heard of "The Service Manager" but when I checked it out, it looks geared to a field intensive business. (i.e. most of your direct labor is out at job sites) We are strictly a...
Thank you all. I really appreciate the input. I will x-ray the strands at the ends of the tee and at the areas of cutting. Will the un-bonded strands be in a metal sleeve? I will obviously look at the ends of the cut to see if the strands are un-bonded, and monitor the tee's performance...
I didn't mean to imply the tee's were made like hollow core slabs, but rather, if the hollow core slabs are pre-stressed, cast in one long sheet, then cut to length; it is reasonable to expect a double tee with a straight strand pattern to be able to be supported in two places, have a small...
Thanks Spats. Maybe "draped" is the wrong word. The strand patterns for these members (8DT-24) in the PCI handbook indicate either straight strands, or, if you need greater strength, strands that are closer to the top of the stem at the ends and close to the bottom of the stem in the middle...
Has anyone sucessfully seen a cut stem of a double tee? I have a double tee roof that needs to have the stems of the tees cut for an elevator. The stems will be supported where they are cut and the span is signifigantly reduced. I have a design that considers the structural integrity of the...
Like I was implying, you may give a good client a break on the labor savings, but you need to get paid for the additional risk. Don't be that guy who rubber-stamps repeat sets for $100. It hurts everyone else in the short run and will hurt you in the long run.
Along the lines of what csd72...
I don't have an easy answer, but was thinking...you should recover the additional hours that you will spend reproducing the construction documents for this new site: new title block, soils info, foundation steps (if required)... Then add enough extra fee to make sure you recover the same amount...
Thanks Haynewp. We too seem to ignore any special treatment of slabs unless there is a special design consideration. The local building officials don't seem too concerned about swimming pools as they are considered acessory structures. I was just at a site visit the other day and saw that the...
We have a debate about frost heave at the interior slab of a shot-crete pool or open tank. Example: A 20'x 40' pool that is 5' deep is well below our 30" frost depth, but if it were totally drained in the winter, what are the effects of frost on the slab in the center of the pool? Points...
I have 2 ideas, both with some drawbacks -
1. Bear the truss on top of the wall and have the parapet be built into the truss. This may require a triple top plate, or studs located directly below each truss depending on your load.
2. Provide (2) 2x10 blocking between studs at the truss...
vmirat, thanks for sharing your method. I agree with your load of 18psf. Was it arrived at by a use of engineering judgement, or some function of the 45 degree angle? Assuming a 45 degree chunk of snow falls out between the slats leaves around 29 psf of snow. I know more than a pound of snow...
Thanks blake989. In my area the ice thickness is .25" while I have a snow load of 30 psf. With 2x6 framing at 6" o.c., the snow load controls at 3.75 #/ft versus 1.81#/ft for the ice. The support beams carrying the joists are the controlling members. Nonetheless, I am going to design the...
Is there a code provision to reduce the snow load on a lattice type structure such as a pergola? (IBC or ASCE7)
When the joist members are far enough apart, the snow only collects on the surface area of the members. Other times, however, the members are close enough together that I feel the...
If the deck is too high to support the tub with a slab, analyze the deck framing with the Hot Tub in the worst places possible for each member. You never know if they might decide to position the tub differently than they indicated to you. This will involve several load cases. For a simple...
