What are the methods of entrusting construction project supervision?
Under different construction project organization and management modes, different methods of entrusting construction project supervision can be selected.
(1) Construction project supervision entrustment method under the parallel contracting model
The parallel contracting model is beneficial to shortening the construction period and Controlling quality will also help construction units choose construction units from a wider range.
However, the shortcomings of this model are: the large number of contracts will cause difficulty in contract management; the difficulty of project cost control is as follows: first, the total project price is difficult to determine, which affects the implementation of project cost control; second, The project bidding tasks are large and multiple contract prices need to be controlled, which increases the difficulty of project cost control; third, there are many design changes and modifications during the construction process, resulting in an increase in project cost.
Under the parallel contracting model, there are two main forms of project supervision entrustment:
1) The construction unit entrusts a project supervision unit to perform supervision;
2) The construction unit entrusts multiple project supervision units to carry out supervision.
(2) Construction project supervision entrustment method under the construction general contracting model
The construction general contracting model means that the construction unit outsources all construction tasks to a construction unit as the general contractor. The contracting unit can subcontract some of its tasks to other construction units, forming a construction organization and implementation method of a general construction contract and several subcontracts.
Under the general construction contracting model, the construction unit should usually entrust a project supervision unit to implement supervision. This will help the project supervision unit take overall consideration of project quality, cost, and progress control, and reasonably conduct overall planning and coordination, which is conducive to Implement construction project supervision work.
(3) Construction project supervision entrustment method under the general project contracting mode
General project contracting means that the construction unit combines engineering design, material and equipment procurement, and construction (EPC) or design and construction (DB) and other work are all contracted out to one unit, and the contracting unit is fully responsible for the project construction organization and implementation such as project quality, safety, construction period and cost. Projects contracted under this model are also called "turnkey projects."
Under the general project contracting model, the construction unit should generally entrust a project supervision unit to carry out supervision. Under this entrustment method, the supervision engineer needs to have relatively comprehensive knowledge and do a good job in contract management.
