What is the calculation method of the type and start-end date of the claim item?

(1) Claims arising from delayed issuance of drawings. The bid-winning construction enterprise has the right to obtain all drawings, technical specifications and other technical data provided by the owner or its entrusted design unit free of charge within 28 days after receiving the bid-winning notice, and make technical disclosure. If the construction drawings and related materials are not received within 28 days, the construction enterprise shall file a claim in accordance with the contract. The 29th day after receiving the bid-winning notice is the start date of the claim, and the date of receiving the drawings and related materials is the end date of the claim. Because it is the preparation stage before construction, this kind of project generally only claims the construction period. When the corresponding construction machinery comes into play and reaches the construction level, if the construction cannot be carried out without detailed drawings, a claim for mechanical stagnation fee shall be made.

(2) Claims caused by bad weather conditions. Divided into engineering loss claims and time limit for a project claims. Owners generally insure the projects under construction, so engineering losses caused by bad weather can apply for compensation from insurance institutions. If the project under construction is not insured, the claim shall be made in time according to the terms of the contract. The calculation method of this kind of claim is that the first day when bad weather conditions begin to affect is the start date, and the end date of bad weather conditions is the end date of the claim.

(3) Claims caused by engineering changes. It is divided into construction and change, engineering increase or local scale and quantity change. Calculation method: the date when the construction enterprise receives the written engineering change instruction from the supervision engineer or the change drawing issued by the owner is the starting date, and the completion date of the change project is the termination date of the claim.

(4) Claims caused by unforeseen events of experienced contractors. Due to the incompleteness of construction drawings or other technical data during project bidding, some engineering contractors can't make correct calculations, such as geological conditions and foundation treatment. Such projects generally claim that the number of projects has increased or new technologies and equipment need to be re-invested. Calculation method: the first day when the contractor's unforeseen circumstances begin to appear is the start date, and the end date is the end date of the claim.

(5) Claims caused by external environment. Claims caused by external environmental influences (such as land acquisition and demolition, construction conditions, land use rights, etc.). ). According to the construction plan approved by the supervision engineer, the first day of the impact is the start date, and the day when the owner coordinates or the external environmental impact disappears on its own is the end date of the claim. This kind of project generally claims construction period and construction machinery stagnation fee.

(6) Claims caused by supervision engineer's instructions. The start date is the written instruction received from the supervision engineer, and the date when a certain work is completed according to its instruction is the end date of the claim event.

(7) The starting and ending dates of construction enterprise claims caused by other reasons shall be determined according to the specific circumstances.
