What is the entrusted work content of the construction project survey contract?

A construction project survey contract refers to an agreement reached between the employer and the surveyor to complete the survey and study of the geographical and geological conditions of the construction project and clarify the rights and obligations of both parties. Construction engineering investigation refers to the activities of identifying, analyzing and evaluating the geological and geographical environment characteristics and geotechnical engineering conditions of the construction site according to the requirements of construction projects, and compiling construction engineering investigation documents. The contents of construction engineering survey generally include engineering survey, hydrogeological survey and engineering geological survey. The purpose is to find out the information of natural geological conditions such as topography, stratum rock and soil type, geological structure, hydrological conditions, etc. of the engineering construction site, make appraisal and comprehensive evaluation, and provide scientific basis for the engineering design and construction of the construction project. As far as the needs of specific projects are concerned, the surveyor may be entrusted to undertake one or more tasks, and the scope and achievement requirements of the survey work shall be clearly stipulated when concluding the contract.

1. engineering survey

Engineering survey includes plane control survey, elevation control survey, topographic survey, photogrammetry, line survey and drawing survey map, aiming at providing basis for site selection (route selection, design and construction) of construction projects.

2. Hydrogeological survey

Hydrogeological survey generally includes hydrogeological mapping, geophysical exploration, drilling, pumping test, groundwater dynamic observation, hydrogeological parameter calculation, groundwater resource evaluation and groundwater resource protection scheme. Its task is to provide detailed information about underground water sources for water supply.

3. Engineering geological survey

Engineering geological survey, including site selection survey, preliminary survey, detailed survey and construction survey. Site selection investigation mainly solves the problem of determining the project address; Preliminary survey is to do basic work for preliminary design, while detailed survey and construction survey are mainly to evaluate the foundation of the construction project and conduct in-depth survey on foundation treatment and foundation reinforcement.
