What are the contents of the field investigation?

Before entering the site, the relevant personnel of the engineering department shall be organized to conduct a detailed on-site investigation on the construction site and surrounding environment. Check whether the topography, above-ground objects, underground pipelines and hidden objects, and groundwater level in the drawings are consistent with the actual situation on site. Whether there are factories, salt ponds, salt flats and ponds around the site. Determine the orientation of the factory, salt pond, salt beach and salt pond and the distance from the site.

The relevant units should carefully understand the requirements for the retention and disposal of the above-ground objects in the construction area. Do not have the construction conditions or construction difficulties, should be timely negotiated with the construction unit to solve. If the original trees need to be cut down, they must apply to the relevant units for demolition procedures, and can only be removed or cut down after approval.

Burying of underground pipelines and concealed objects requires the construction unit to provide relevant completion drawings of underground pipe network. If you can't provide drawings, you need to send someone to check the location of underground pipelines, pipelines and hidden objects on the construction site.

Extended data:

The tenderer shall organize the bidders to conduct on-site reconnaissance on the objective conditions such as the site and surrounding environment of the project. A tenderer may organize bidders to conduct on-site reconnaissance according to the specific conditions of a project subject to tender, but may not organize bidders to conduct on-site reconnaissance alone or separately.

When a bidder visits the site, he can further understand the intention of the tenderee and the surrounding environment of the site, so as to obtain useful information, and make a decision on whether to bid, 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.

According to the specific conditions of the project subject to tender, the tenderer may organize potential bidders to inspect the project site. Inspection refers to the on-site inspection conducted by the tenderer on the objective conditions and environment of the project implementation area, such as economy, geography, geology and climate.

After issuing the tender announcement or invitation letter, the tenderer may, according to the actual needs of the project subject to tender, notify and organize potential bidders to conduct on-the-spot investigation on the project site. This kind of bidding project is usually an engineering project.

Potential bidders can go to the site to inspect whether to decide to bid or prepare bidding documents, further understand the tenderer's intention and surrounding environment, so as to obtain useful information, and make a decision on whether to bid or bid strategy and bid price accordingly.
