After the foundation is accepted, the installation will be carried out immediately. The civil construction foundation has been completed every now and then. The strength of the concrete foundation has rebounded and met the design requirements. There is no problem, but the equipment cannot be installed in any case. The owner was anxious and the general contractor was under great pressure, so the construction progress of the equipment installation company was forced to delay. In the end, I had to cut my feet and walk on the shoes, so I could only "cut the vegetables in the square and round" with the scimitar. Either make an enlarged chassis to hold the equipment, or re-excavate and widen on the foundation side to re-pour the foundation, which eventually ruins the power of the ox and tigers, and makes everyone feel depressed.
Begins and goes step by step. Such a ridiculous thing happened in
. There are many reasons for analysis. The main reasons are the following four:
1. When measuring and laying the line in civil engineering, the anchor bolt hole was not strictly set up according to the design requirements of the drawing. The measurement error was large and exceeded the scope allowed by the design;
0. Measurement and laying the line is the guarantee of the correct construction of the project.
2. No instrument retest was used before the reserved anchor bolt hole was supported. If the wiring error is found in this way, it can be corrected;
3. During the concrete pouring process, the on-site inspection was not strictly controlled, and the reserved hole formwork was displaced, and the error generated exceeded the allowed range of the design;
0 The formwork cannot be displaced when pouring concrete
4. The civil construction has been completed, and the reserved hole design measurement and re-test verification is correct, but in order to save investment and reduce costs, the general contractor privately changed the specifications and models of the equipment, forgetting the reality that the civil construction foundation has been completed.
The difference is a slight loss hiccup
I am a senior project management worker, follow me, I will share with you more practical and down-to-earth project management professional knowledge and practical experience in engineering management.
