It’s the same sensation of gut wrenching trauma the Montreal furriers’ felt when PK Subban was traded to Nashville.
What just happened? Well, due to your newly installed porch railing section having just failed the shake test, you, like the furrier shops, will be suffering a yet to be determined financial loss.
When a newel post, which is essentially the backbone of your spindle and rail system, fails the shake test, it brings two things into question.
One, is the newel post perhaps missing a few lag screws, and simply lacking the proper blocking (when extra pieces of 2×8 lumber are used to secure the post into the joist system)?
Or two, has the newel and subsequent railing system been installed in a manner that contradicts the stamped drawings regarding this product?
If it’s a case of adding a little lumber and a few screws, then the burden is one more trip to the lumber yard, and yet another opportunity to pick up a coffee and blueberry muffin at the local drive-thru.
If it’s a case of the railing not meeting code, or being improperly installed, the sense of nausea is your body’s reaction to the fact this deck is yet going to require more time, and money.
What is the shake test? The shake test is a battle between a fixed 4×4 newel post, made of either treated lumber, aluminum, or composite matter, and one motivated inspector. I’m not sure what amount of education and practice is required before an inspector attains his “shake ’em up” certification.
What we do know is that the training is intense. Once the inspector gets his or her hands on the newel, and the “shake” procedure begins, it would take a crow bar to pry their fingers off. Basically, the integrity of the post is challenged by clasping the top of the newel, and with subjective force, an attempt is made to move this post backwards and forwards.
If the degree of deflection (the measure to which the post can be forced off its 90 degree perch) is significant, the inspector will ask for the proper documentation regarding the manner of install.
This “documentation” element is going to be the make-or-break factor in how well the rest of your day is going to proceed. Either the next few hours will be spent in calm repose, once the documentation confirms your manner of install as being correct. Or alternatively, an error or omission is discovered in the strategy, leading to you performing donuts on your front lawn in therapeutic frustration.
As a homeowner about to build a deck, especially if a pool’s involved, it’s important to understand one key point. Your deck drawings may have been good enough to earn you a building permit, but this in no way signifies your deck and railing system is to code.
In other words, the building permit has simply OK’d your drawing. From this point on, it’s up to you to follow code, and have the proper engineered stamped drawings regarding your chosen components.
As an example, a deck plan with newel posts placed at every 8 ft. on center, will pass the permit stage.
However, not all railing systems are permitted to span 8 feet. Some composite railing systems are stamped acceptable for 6 ft. on center newels only.
Vinyl, composite, and aluminum railing systems, all have their specified manor of install, which will differ from wood, and even from manufacturer to manufacturer.
What happens is that 8 ft. composite railing sections get purchased and installed, and then it’s discovered the Ontario building code has only approved the 6 ft. long series of components.
Or, the newel posts get surfaced mounted to the deck, when the approved drawings indicate they should have been integrated into the joist system. So, avoid those big headaches by procuring the stamped drawings regarding your specific chosen line of products, first.
Then, proceed accordingly.
