It includes contract agreement, letter of acceptance, bidding documents and Q & A, addenda, bid and annexes, general terms and conditions of contract, special terms, standards, technical specifications and relevant technical annexes, drawings, bill of quantities, project quotation or budget, etc.
As the main pier of the project is located on both sides of the Beijing Hangzhou Grand Canal, the construction technology and protective measures of setting temporary buttresses in the water have great technical difficulties.
Claim skills in construction claim in construction is actually to timely and reasonably put forward to the owner (or Party A) the changes of project content, construction conditions, geological changes, construction period and many other conditions in accordance with the relevant provisions of the contract in case of changes in project content, construction conditions, geological changes, construction period and so on, As a result, the contractor paid extra project costs and asked for economic compensation.
2.
The project department has made a detailed construction organization design for the above two schemes and submitted it to the owner and the supervisor.
When reading the contract terms, pay particular attention to the description of project change, material rise and construction period change in the special terms, find out the terms favorable to the contractor, and understand the actual meaning of the terms in order to demonstrate the legitimacy of claims against the owner in the future.
Most civil engineering projects have the characteristics of large scale, long construction period, unique natural and geographical conditions, so that contractors often encounter changes in project content, construction conditions, geological changes, construction period and many other situations in the process of project management, which makes it convenient for contractors to change the construction organization design and adopt new construction schemes, Either in order to ensure the construction period, the investment of resources is increased, or the construction cost is increased, or the construction period is prolonged, resulting in the deterioration of the project cost.
The owner clearly states in the bidding documents that he is only responsible for providing access roads, water and electricity facilities and the prefabrication site of middle beams, Other temporary works are not prompted.
Because the depth of engineering design is not enough, the owner’s risk is large, and the basis of contractor’s claim is easier to find.
Due to the change of the proposed steel pipe erection site, it must be changed to horizontal arch erection site.
After the approval of the owner and the supervisor, we successively submitted the following reports according to the budget preparation method agreed in the contract: ① construction claim report of steel pipe pile water platform; ② Claim report for steel pipe arch erection and site hardening..
The owner specified in 23.2 of SCC that other factors that can adjust the price are: “① design change; ② on-site visa of the owner’s representative and the supervising engineer”, and agreed that if there is no same and similar unit price for the project change, the budget can be prepared and re negotiated according to the local municipal quota and the current market information price.
The drawings during the bidding are based on the preliminary design drawings.
The design institute also believes that in the construction of main piers on both sides of the canal, the construction scheme of temporary buttresses in water and the scheme of steel pipe arch erection and site hardening must be set, and the modification design is supplemented.
2.1 carefully study the bidding documents and capture the claim opportunities from the source of the project.
After repeated demonstration by experts, it is agreed that the above scheme is necessary and feasible.
Therefore, enterprises can get more profits only by effectively adjusting prices and claims in construction project management.
In particular, after obtaining the construction drawings, we must carefully check the two drawings, find out the differences, and make records in case of claims.
Obviously, the design depth of bidding drawings is not enough.
It is an important management measure for contractors to legally safeguard their own interests in project management.
Overview in recent years, with the state increasing the legislative intensity and management of the construction industry management, the engineering project construction management has become more and more standardized.
For example, in the early stage of the construction of a municipal bridge project, according to the bidding data handed over by the business department of our department, the bid winning price of the bridge is 35131907 yuan (including the provisional sum of 3640000 yuan).
Therefore, in the project management, contractors should not only strictly manage the construction period and quality according to the contract, but also effectively pay attention to price adjustment and claim, so as to make the project obtain better benefits.
Secondly, the project bidding using preliminary design drawings.
At present, due to the fierce market competition, the profit space of construction enterprises is becoming smaller and smaller.
There are relatively successful cases in this regard.
Secondly, due to the change of the proposed steel pipe erection site, it must be changed to horizontal arch erection site.
1.
Therefore, the contractor must be good at capturing this change in project management and submit a claim report to the owner timely and accurately according to the relevant provisions of the contract, so as to effectively increase income, reduce losses and improve the economic benefits of the enterprise.
After commencement, according to the progress of the project and the terms of the contract, the project department first put forward the construction scheme that temporary buttresses in water must be set in order to ensure construction safety and project quality during the construction of main piers on both sides of the canal.
Therefore, the steel pipe arch erection and site hardening scheme are also proposed.
We can only consider the conventional construction when bidding.
Similarly, enterprises can only develop and survive if they get certain profits.
In addition, the bidding drawings, instructions to bidders, Q & A, addenda and other relevant documents never mentioned the explicit or implied treatment of the construction scheme of temporary works in the water of the main pier of the bridge.
First, whenever a project wins the bid, the relevant personnel of the project management department, the executing agency of the project, should carefully and carefully read the bidding documents and contract documents issued by the owner.
As the civil engineering projects we undertake are basically obtained by bidding competition, the fierce market competition makes our profit space smaller and smaller, and the contractors focus on price adjustment and claim without exception.
Moreover, the disposal of these technical aspects also depends on the support of the maritime safety administration of the local government department to a large extent, which is difficult.
