(1) When the pump foundation is handed over, it should come with a quality certificate and measurement records. A clear baseline should be established, and the elevation of the baseline, as well as the vertical and horizontal centerlines, should be clearly marked. The building should also have coordinate axes marked for reference. For large-scale or critical pump foundations, settlement observation points should be set up and monitored regularly to ensure stability and safety.

(2) During the inspection of the pump foundation, the surface should be free from cracks, honeycombing, voids, or other structural defects. Special attention should be given to high-temperature magnetic pumps, as any imperfections in the foundation could affect their performance and longevity.
(3) Based on civil engineering drawings and pump technical documentation, the position, direction, height, and dimensions of the pump base must be rechecked. The allowable deviations should follow the specifications outlined in Table 2-35 below:
**Table 2-35: Allowable Deviation for Pump Base Size and Position (mm)**
| Substandard Name | Permissible Deviation |
|------------------|------------------------|
| 1. Base Coordinate Position (Vertical and Horizontal Axis) | ±20 |
| 2. Elevation of Base Plane | -20 |
| 3. Base Flat Overall Dimension / Hole Size | ±20 / -20 +20 |
| 4. Levelness of Base Plane | Full length per meter: 5, 10 |
| 5. Verticality of Base | Per meter full length: 5, 10 |
| 6. Embedded Anchor Bolt: Elevation (top), Center Distance (root and top) | 20, ±2 |
| 7. Reserved Anchor Bolt Hole: Depth, Center Position, Hole Wall Verticality (full depth) | ±20, ±10, +10 |
| 8. Embedded Slotted Anchor Bolt: Elevation, Center Position, Level (slotted anchor plate), Level per meter (screw hole anchor plate) | +20, ±5, 5, 2 |
This detailed review ensures that the pump installation meets all required standards and will operate safely and efficiently once in place. Always double-check measurements and consult with engineers if any discrepancies are found.
