Temporary Building Shoring Risk Mitigation Measures

Temporary Building Shoring Risk Mitigation Measures

Temporary Building Shoring Risk Mitigation Measures

(OP)
Ladies and Gents,
Long time reader, first time poster here. I recently transitioned out of the Army as a Combat Engineer Officer into an Operations Manager role for a mechanical contractor. We are scheduled to undertake a substantial project consisting of the demo of existing equipment and the installation of new food-processing equipment in our client's facility during an 8-day shutdown. Due to the impacts of COVID-19, a previously scheduled structural column replacement (to be performed by a third party) has been delayed several months and is now being thrown smack-dab into the middle of our shutdown. The client's project manager has stated there will be a "40' safe zone" established around each of the four structural columns to be replaced (which support the load of the roof), shoring will be erected, then all "work in the process area will be stopped for 30 minutes to ensure the shoring will hold." It may be my ignorance, but my project managers and I do not feel that these are sufficient risk mitigation measures, considering we will have 20+ personnel in the immediate area. I have pored through OSHA regulations and gone through countless threads on the forum, but haven't found any hard regulations on safety requirements when removing a structural member. Other than asking for stamped drawings for temporary building shoring, is there anything else we can do in order to ensure the safety of our team members and fellow contractors? Thank you for any and all assistance!

Cheers!
Essayons!

RE: Temporary Building Shoring Risk Mitigation Measures

I agree with your concern, but also share your ignorance of any hard and fast regs on the subject. Stamped drawings of the design and also certification by an appropriately qualified inspector after erection are certainly a good place to start. The "30 minutes to make sure it holds" doesn't instill much confidence, though.

What would it take to make your crew feel comfortable and confident they'll all go home in one piece each day of this job? Does your company have an industrial safety expert on staff? If not, you may want to contact a consultant and have them take a look at the situation.

RE: Temporary Building Shoring Risk Mitigation Measures

I've been privy to a couple of column moves/replacements inside existing buildings. Luckily none have had significant issues, but what issues did arise normally arose within the first couple of minutes/hours of the shoring taking the load. Once the shoring is in place and loaded, it's not incredibly different from a regular column risk.

That is assuming the shoring is adequately designed for the loading imparted to it. In the couple of shoring designs I've reviewed they are generally "over-designed" for the loads to provide some redundancy since the consequences of failure are quite high.

RE: Temporary Building Shoring Risk Mitigation Measures

As jayrod stated above, I wouldn't worry too much on the strength of the shoring. But, since it looks likely multiple crews will be present at the same time, I think you shall ask the plant manager to hold a pre-task coordination meeting, to iron out details and safe work procedures. Each crew knows more about the other crew's task and operation, the safer the execution of the project.

RE: Temporary Building Shoring Risk Mitigation Measures

Essayons RCP 23:
Retired13’s idea of a “pre-task coordination meeting,” seems like a really good idea; with the client laying down the law, that the two teams have to cooperate and work together. The column guys are the ones who changed their schedule, and know you are the one being inconvenienced. Your completion date should possibly be extended to allow you to work safely and unincumbered; an incentive to get the client to cooperate and insist on same from the others involved. Can they shore and work on one area/col. at a time, so that you can keep working, unhampered in other areas. Can you come in first and clear your old equip. out of their way to make their work quicker and cleaner; then come back to that area to install your new equip. when they move to the next area? And, move down the line this way. Will you be given some benefit/credit for doing this? You won’t even be in the immediate area while they are shoring and un-shoring for each col. Can you share some moving and lifting equip., etc. to minimize extra equip. in the area. It is fairly typical that the more contractors (individual sub-projects) you crowd into one area, the more they get in each other’s way, and the better the argument that you/they interfered/held up the other contractor. So this situation does require some special planning and management. I think plans, calcs., schedule, etc. for their work and shoring, signed/sealed by a P.E. are a min. that they should furnish to get started on this planning and coordination effort, and the owner/client should support this. Of course, you must come with your schedule and an open mind toward cooperating. This isn’t the/your military any more, where you say jump and everyone asks ‘how high’ and then jumps. It’s a bit more like herding a bunch of independent cats.

Edit: Bldg. Codes, OSHA, bldg. specs., etc. do not always cover every imaginable situation in the entire universe, although they keep trying, with ever thicker cookbook like newer eds., each less coherent, and more convoluted, than the last. You might be looking for (want to look at) some of the more general sections, paragraphs, etc. There is considerable general verbiage which suggest that designs should be done and overseen by competent Professional Engineers and Archs., with special inspections where needed; that the work should be done by competent contractors, mechanics and workmen; that the work should be done with the health and safety of the public and the workers always in mind, etc. Then, you and your attorney, and your insurance carrier make what you wish (what you will) of those general statements, to try to stay out of trouble and perform your work responsibly and cooperatively.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
