    Hot-Tub on an Exterior Deck

    If the tub is 8 foot square, the heaviest ones (Cal Spa) are just under 1500 pounds, and no more than 500 gallons. The SouthernPine site has span tables for 150 lbs/ft joists: http://newstore.southernpine.com/images/ref202.pdf

    Limiting Height in Wood Construction

    If someone wants stick that tall, my guess is they should go with steel stud.

    " life of structure"

    Who is asking the question? An investor? It's impossible to guarantee a building's life. Unless you can guarantee the viability of a society. If you have societal breakdown all bets are off. Aluminum siding has an outstanding lifespan, but not if a homeless person has a shopping cart, a...

    Steel Cable Infill for Stair Guardrail

    Until the code explicitly forbids horizontal infill any challenges should be successfully appealed. It probably comes from the inspector's childhood.

    Steel Cable Infill for Stair Guardrail

    Judging from client list and catalog offerings, this firm may be the authority on cable railings. http://www.secosouth.com If you took a look at the allform site, practically none of their portfolio meets code for infill.

    Steel Cable Infill for Stair Guardrail

    I think the code challenge is properly stated. However, these folks may be able to offer some insight: http://www.allformwelding.com/allform_026.htm

    Positioning spring to lift ramp

    What is a lowloader? I don't think you are talking about a liftgate, are you? Liftgates use a wound spring and that spring might be a great place for you to start. If you know what I am speaking of, go look at a liftgate or two. My best guess is you are speaking of a 'beavertail' ramp for...

    Cement mixture

    Are you sure you can't find a commercial product that satisfies your needs? Cinder blocks are made of an extremely dry mixture that is vibrated and compressed into the molds. Extremely noisy, due to the vibrators being used. I don't think the cost-saving would be worth the effort of packing...

    **Spiral Staircase Column: 20-axis bending+compression?

    I think a 16" diameter would allow a welder to crawl inside and install plates to transfer force to the opposite wall. He won't like it in there, but it's not a career. What happens if you go larger diameter.

    Subfloor load for Pool Table

    You can check the before/after floor deflection from below. If you have a stud detector and can align the legs to sit directly over joists, do it. If the flooring sags, the pool table will communicate the fact to you by failing to maintain a level playing surface. I worked a year in the...

    Timber Ramp using 2 x 10s

    You could purchase 2 by 12s, 14 or 16 foot long and rip them into wedges. Drill them for 1/4" threaded rod and 'string' them together to create ramps. One plank will create two ramps. Depending on your taste, you can create two ramps and go with that, or you could create several ramps and then...

    Hot tub adjacent a retaining wall

    GeoPaveTraffic, I agree with you about proximity to the wall, and whether the wall "squares off" the slope profile. If the wall was strictly a cosmetic attribute I wouldn't be too worried, but here the wall is being expected to keep the spa from sliding down the hill into the neighbor's deck...

    Hot tub adjacent a retaining wall

    Friend asks me to provide guidance on "moving a hot tub". Turns out the actual "moving" can be accomplished with rollers. About 20 feet over level ground. Unfortunately, that "level ground" abuts a freshly created retaining wall about 3 foot high, the wall itself resting on hillside. The wall...

    Ply gussets in wood truss

    If you gents don't mind a question: Last time I looked at "extension service" documents on nails, screws and trusses, seemed like screws were rated at twice the pullout of nails. As far as screws being brittle, it depends on the screws. Brass isn't brittle, and neither is the last batch of...

    FIBER WRAPS FOR RENOVATION OF POWER POLES

    Just wondering about cutting off the tops of the poles and filling with an engineered concrete? I assume highly plastic and chopped glass fibers.

    Artificial reefs to create surf

    I would question the economic return on such a project, but here in the States certain legislators ensure the loyalty of voters by restoring the sandy beaches of vacation hotspots. This is not cheap, nor long-lived. What sort of "surf" do you want? If you want Surfer's Paradise waves, that's...

    Bulging Concrete Block Basement Wall

    The only reason I could claim to know anything about this is the crash course I took upon myself when interested in a house with a buckled basement wall (block). In theory, you would need to straighten the wall, and place #5 rebar in the cells (closer to inside wall) and then grout it. Or rely...

    Bulging Concrete Block Basement Wall

    There are a few styles of franchised remedy. One is to use deadmen plates in the surrounding soil and plates on the interior wall. They are tied together with threaded rod. Check the Yellow Pages, most likely you can get a quote over the phone...
