Is There Any Problem if the Grouting Under Base Plate Delayed?

07/29/2015 1:19 AM

Hi,

In my project, the grouting under base plate are not done and the glazing works to the installed skylights are in progress.

I would like to know whether any structural impact if the grouting under base plate is delayed.

Your early reply is appreciated.

Everything will be fine.

The grouting under base plates is just cosmic cosmetic.

The only structural impact will be when if the skylights fall out.

Will this structure be occupied by anyone you know?

"...the glazing works to the installed skylights are in progress...."
Too late!
But then if the bus is too late and you are too early you will get it!
Please explain where the delay is! If grouting was structural and is still done it should be no problem.

The machinery that is located on the base plates:

  • Is it operating now?
  • When will it be operating?
  • How heavy is it?
  • Why is the grouting delayed?
  • Where is the machinery?
  • Will the base plates be subjected to wash down water or flooding?

Do you expect an answer of value for such a moronic question?

If you don't know what is missing here, then you are really missing the point of CR4.....

Andy: You sort of nailed the lid shut on this one! ROFLMAO!

Yes it will make a difference (to the OP), if anything is allowed to shift/settle after the glazing is done on the skylights, or another moron comes along with an "out-of-control" wrench, and "adjusts" some of the bolts on the base plates. We are talking about the columns supporting the roof to this well lit building? Wow, I feel sorry for whoever is buying this load of **** from your company!

It is not cosmetic...It help distribute uniformely the load on the concrete and prevent rusting the anchor-bolts.

You should do it until turn-over.

You can get away with a short delay, the sooner you get the grouting done the better. You can rely on the on the shims only for a short period of time, that is, making the assumption that you do have at least 4 piles of shims under each base plate.

Is this a baseplate for a steel column, girder, or beam?

Grouting of any structural steel element should be accomplished with a Non-Shrink/Non-Metallic Structural Grout completed after said element(s) are aligned and plumbed, ALWAYS BEFORE any subsequent ancillary overhead construction work is to begin.

Without said grouting you are only relying on the structural strength of anchor bolts (and possibly structural steel shims/wedges) to support an applied load. You are risking all completed and ongoing constructs, equipments, and the lives of all construction workers being supported by the affected structural members.

This is a MAJOR FOUL-UP!!!!! SNAFU and a FlusterCluck....

Well it depends alot on the structural layout, detailing and loads. Is this a very big structure or just a small skylight structure ?

You are currently relying on the shims transmitting the load to the concrete base.
This may create a compressive stress in the concrete which is over its capacity.
Then you get settlement and maybe failure.

Perhaps the baseplate is a moment connection ? In which case you may be overloading the anchor bolts too due to reduced lever arm.

Quite a bit more information is required before a good response can be made.

In your situation, you must have an engineer who looks after the project. So you really need to get that person to respond.
If you don't have someone like that on the project, you should get someone.

Best not to leave it till you have to get the insurance people in. That can be a very big pain.
Without mentioning that you are possibly taking a risk with people's lives or well being.

So, stop/reverse the glazing and turn the gas up under the grouting operation! Sheesh...
