2、a project:from May 20 to May 26,the project was shut down due to the failure of the contractors construction equipment,and from May 24 to June 9,the project was also stopped due to the delayed delivery of drawings of the owner.How many days can the contractor claim for the construction period?nThe f

3、ailure of the construction equipment is the responsibility of the contractor,so the contractor is not entitled to claim compensation from May 20 to May 26.The delayed delivery of drawings is the responsibility of the owner,and the contractor is entitled to claim for the construction period,which is

4、14 days in total from May 27 to June 9.2.The proportional analysis methodAn accident occurred in the foundation construction of a project,resulting in the increase of project quantities from the original 2800m to 3500m,and the original construction period is 40 days,then how many construction days t

5、he contractor can claim for?Claim value of the construction period=original construction period the quantity of new work/the original work quantity=40(3500-2800)/2800=10 daysThe claim value of the construction period=the contract construction period the quantity of new work(or the cost of new work)/
