Construction surveying is the scientific discipline of measuring and determining positions on construction sites using various instruments and tools. It provides a basis for construction work and ensures the quality of construction. Conducting construction layout before the start of work for each unit, sub-item, and sub-section, as well as equipment installation, can provide construction markers such as axes, centerlines, and elevations for subsequent construction and equipment installation, thereby ensuring the quality and progress of the project.

An overview: Every construction project must undergo measurement prior to commencement, making pre-construction measurement a crucial factor for timely and smooth start. Construction measurement, also known as staking, is an indispensable technical management aspect in civil engineering. Different stages require construction measurement both before and during the project, ensuring that it permeates the entire process and plays a decisive role in the quality and progress of the project.

We are integrating construction survey management into the overall project management, tapping into the hidden functionalities of construction surveying to fully leverage its role in project management, making it the leading force in the management process. 2. The Impact of Construction Surveying on Quality The progress of construction surveying in positioning and laying out directly affects the quality grade, structure, safety, and subsequent operational performance of the project. To ensure the quality of the project, it is imperative to first guarantee the quality of the construction surveying.

Therefore, enhancing the quality management of construction measurements and effectively controlling the entire measurement process to ensure accuracy is a necessary task for us to guarantee the quality of the project.

1. Construction Preparation Phase:

The field plane control network and elevation control network shall be surveyed according to the construction drawings, ensuring consistency with the design.

2. Construction Phase:

According to the engineering progress, the positioning and alignment of objects, axis control, elevation leveling, and vertical projection are used as the basis for construction in accordance with the drawings.

3. Completion Phase:

Inspect the actual plane positions, elevations, vertical directions, and relevant dimensions of all major parts of the inspection engineering, which serve as the basis for the completion and acceptance of the project.

4. Deformation Observation:

Observations of settlement, horizontal displacement, and tilt deformations are conducted at the engineering sections for design and construction, in accordance with the planned cycles, serving as the basis for verifying the quality of engineering design and construction.
