The contractor's comprehensive strength and overall level are stable within a certain period of time, and it is impossible for a certain project to suddenly improve significantly. Therefore, it is necessary to examine similar projects recently constructed, and at the same time investigate its social evaluation.

On-site inspection of projects is an important part of pre-qualification. It must be emphasized to bidders that the projects inspected must be real. Otherwise, some loose conglomerates have great individual differences and the inspected projects cannot reflect the real situation.

The inspection of contractors is not only to select a team, but also to understand their characteristics and manage them accordingly in the future. For example, we need to understand its construction characteristics, common quality problems that are prone to occur, etc. through inspection.

When inspecting a contractor, it is necessary to plan in advance what needs to be investigated and formulate an inspection plan. When asking questions during a meeting, you must listen to the other party's statement, do not explain for the other party, and do not add your own opinions, but you must control the situation and cannot let the other party develop aimlessly.

The meeting should be recorded by a dedicated person, and a written evaluation record should be formed through collective discussion after the meeting.

★General Contracting Investigation

Design and construction are separated in the domestic construction industry, and there is no real general contracting. If the construction unit is the general contractor, it can only be a construction and design consortium led by the construction unit to bid. This requires a design entrustment contract with the design unit in the bid, that is, the design unit and the construction unit bundle the bid, and the design must also be inspected. It is unacceptable for several individuals in the construction unit to undertake the design work.

To generalize, before bidding, all aspects of the design work in the bidding process must be coordinated and arranged. During the inspection, it is a focus to inspect the design capabilities of the general contractor.
