Do It Right! Lessons from the field not to be repeated

Railing

Railing
  • Try to avoid damaging the paint coating when installing metal railing.
Railing
  • When installing ornamental rail posts, make sure any void between the anchor rod and the hole is filled with epoxy or caulk. Make sure to only use caulk found on our APL and to completely coat the contact surfaces.
Railing
  • Centerline of post is to be installed at least a foot from a joint in the concrete.
  • Base plate of post is to be installed on a bed of approved caulk.
Railing
  • As you can see, this load is still bundled up. The Ironworkers should not even unload it.
Railing
  • When rail posts are being installed, make sure that the base plate is completely buttered with an approved caulk (found on the APL) before tightening the nuts on the anchorages.
  • In this case, they just ran a few beads of a non approved caulk.
Railing
  • Make sure the prime contractor is aware that the ornamental railing always needs to be grounded, and that, with a little forethought, it can be a little more pleasing to the eye than this . . .
Railing
  • No caulking visible under base plate.
  • Rusty hardware!
Railing
  • Make sure of the location of pilasters, lighting, ornamental railing and control joints before you pour the concrete!
  • How will the lighting conduit shown here...
Railing
  • I can never figure out how come this coating damage happens so often!
Railing
  • Free texture! Ask for a painting pre-activity meeting to learn how runs and drips will be prevented.
Railing
  • Not again!
Railing
  • Lots of damage due to no padding being used between contact points.
  • This rail is still bundled up! Send it back to the shop.
Railing
  • Look! We get a special texture without having to pay extra!
Railing
  • Don’t even let them take it off the truck!
Railing
  • What!?
Railing
  • Please don’t accept rail sections if they are scratched this bad when still bundled up.
Railing
  • These are unacceptable anchor rods.
  • A contractor proposal will be needed for the fix.
Railing
  • The rail posts are suppose to be vertical, and the sections of rail panel should be designed to fit into the post correctly even if the barrier isn’t horizontal.
Railing
  • What? Drilling after setting railings destroys the paint! And is exactly where moisture likes to stay!
