I have a question for the experts here: currently, the client is asking us to provide foundation plans.

We specialize in equipment, but now the client is asking us to provide foundation plans. The equipment in question is one with a diameter of 1600 and a height of 10 meters; the medium used is gas. Its weight is approximately 11 tons. The foundation that the client is considering has dimensions of 5m×5m×1.2m. A layer of ash will be laid at the bottom, with steel rebar of type 22@150 (HRB400) used in two layers arranged in both directions; tie rods will also be installed in the middle. The foot bolts are of type M24×800 and are welded to the rebar. The concrete strength grade required is C35. I would like to ask if this setup is appropriate If appropriate, let’s provide the construction drawings. It’s really troublesome: Q is seeking advice from experts.
The stress distribution of the device can be provided to seek assistance with the design
I would like to ask, what does it mean to provide the stress distribution? Weren’t the device weight specifications provided? The wind loads and seismic loads considered for the equipment can be determined in accordance with general regulations.
The stress points on the foundation refer, in simple terms, to the areas where the equipment exerts pressure on the foundation; they indicate the magnitude of this pressure as well as its form.
It would be best to have the design firm handle this task, taking into account information from two sources. First are the drawings of your equipment as well as details regarding the stress distribution on the foundation surfaces; due to the asymmetry of the equipment, the stress is rarely distributed evenly, though the difference is usually not significant, so this aspect needs to be given special attention. Secondly, the client should provide a geological survey report for the location where the equipment will be installed, along with information on local seismic loads. Given that the height is 10 meters, it is recommended that the client also provide data on local wind and snow hazards, as well as other hydrological and meteorological conditions. Once these details are available, the design firm can proceed with the work
Since you are from the equipment field, just reply to the client that you don’t know and can’t do it – that’s it The equipment foundation is supposed to be designed by the structural engineering team; why have you taken on this task?
This is a bit absurd; it’s not within your area of expertise. How dare you? Those in the engineering field can handle piping work, but what about laying the foundation for equipment? It’s completely unrelated, isn’t it?
Those who are not in this field should stay out of it; one has to take responsibility for the output, as things can get complicated if issues arise later
The last edit to this post was made by CHANGBAISHI on 2017-6-13 at 17:23. Hehe, it looks a bit messy; this should be divided into two parts, one being a diagram of the basic equipment conditions； The other is the civil engineering drawing designed based on the basic condition diagram. The former is provided by the equipment manufacturer, while the latter is the civil foundation plan for the equipment, designed by the design agency based on the basic condition drawings provided by the manufacturer, taking into account relevant geological and topographical factors, gas conditions, and other aspects. Party A should carry out supervision based on these drawings.
This should be designed by a civil engineering specialist, but a foundation of 5m x 5m – isn’t that too large?
It should be designed by the structural engineering team, and the size of the foundation should be determined based on the calculations of seismic and wind loads
