What is site investigation in construction engineering?

Construction engineering investigation is a very important stage in construction, and its task is to determine whether the geological conditions and natural environment of the construction project site are suitable for engineering construction. The results provide the required engineering geological and hydrogeological data for the design and construction of single building, and also provide various technical services for the whole construction process.

Such as foundation scheme demonstration and engineering monitoring. Engineering investigation should be undertaken by qualified investigation units and carried out in accordance with certain procedures and requirements. General engineering investigation can be divided into three stages according to work requirements: feasibility study investigation, preliminary investigation and detailed investigation.

The field investigation of extended data is a bidding procedure that bidders must go through. According to international practice, the quotation put forward by bidders is generally considered to be compiled on the basis of on-site inspection. Once the quotation is put forward, the bidder has no right to request to modify the bid, adjust the quotation or compensate because of poor on-site investigation, incomplete understanding of the situation or incomplete consideration of factors.

On-site investigation refers to the on-site investigation conducted by the tenderer on the objective conditions such as the project site and surrounding environment. The tenderer may organize the tenderer to visit the project site according to the specific conditions of the project subject to tender, but the tenderer shall not organize any bidder to visit the project site alone or separately.

When the bidder visits the site, he can further understand the intention of the tenderer and the surrounding environment of the site, so as to obtain useful information, and make a decision on whether to bid or bid strategy and bid quotation accordingly. The tenderer shall take the initiative to introduce all relevant information of the construction site to the bidding applicant. The bidder shall conduct a comprehensive investigation on the site conditions affecting the project construction, including economic, geographical, geological, climatic and legal environment.
