According to "construction project construction bidding methods" stipulates:
"Article 35 The bidder is a legal person or other organization that responds to the bidding and participates in the bidding competition. Any subsidiary (unit) of the bidder that does not have independent legal personality, or any legal person and any of its subsidiaries (units) that provide design and consulting services for the preliminary preparation or supervision of the bidding project, shall not be eligible to participate in the bidding of the bidding project."
According to the above provisions, a project can not and design units and construction units. However, there are exceptions, for example:
According to "Measures for Bidding and Tendering for Survey and Design of Engineering and Construction Projects", it is stipulated that:
"Article 8 For engineering and construction projects that must be tendered in accordance with the law, the bidders may carry out the general contracting tendering for the survey, design, construction of the project, as well as the procurement of important equipment and materials related to the construction of the project. "
As-built drawings for municipal projects should be issued by the construction unit or the design unit, is there a regulation?As-built drawings should be made by the construction unit. Changes with the design drawings by the construction unit to re-draw, no changes in the design drawings stamped as-built drawings.
The design unit can not be constructed with this provision1, according to the "construction project construction bidding and tendering methods" stipulates:
"Article 35 The bidder is to respond to the bidding, to participate in the bidding competition for legal persons or other organizations. Any subsidiary (unit) of the bidder that does not have independent legal personality, or any legal person and any of its subsidiaries (units) that provides design and consulting services for the preliminary preparation or supervision of the bidding project, shall not be eligible to participate in the bidding of the bidding project."
According to the above, a project cannot be both a design unit and a construction unit.
2, but there are cases of exceptions, for example: according to "engineering construction project survey and design bidding and tendering methods" stipulates:
"Article 8 must be bid in accordance with the law of the construction project, the bidder can be on the project survey, design, construction, and construction related to the procurement of important equipment and materials, the implementation of general contracting bidding. "
Engineering construction changes to the construction unit signature or design unit signatureDesign unit signature
Significant modifications to the construction drawings change, must be approved by the original, the design unit agrees
Renovation of the construction unit and the A, supervision, design unit interfaceRenovation of the construction unit with the A, supervision, design unit interface
In this many relationships, the owner The owner can delegate project management (construction) to the supervisory company. Supervision (consulting) company responsible for the coordination of the entire project and supervision and management of the overall responsibility to the owner.
The owner can also manage the project himself if he is able to (this is the case for most small and medium-sized projects). If the decoration company and the design company need to communicate more frequently by the owner to be a special authorization, the decoration company directly with the design company to contact, and arrange the appropriate way to the owner, the superintendent report.
Renovation of the as-built drawings and design units to draw or construction units to draw
Not the design institute to draw, it is the construction unit you out of the construction drawings to cover the construction unit of the as-built drawings chapter. If the construction of small changes in the construction unit to be marked on the drawings. If the construction unit lacks a new archive of drawings will look for the design institute to be, the design institute to charge the cost of the sun.
