Please explain

DELAY CLAIM 1: UNFORESEEN CONDITIONS contaminated soil that forced the c d on- tractor to change plans. The contractor incurred extra costs because of the hauling and disposal of the contaminated soil. In addition, excavation took 12 workdays rather than 7 workdays. The contractor issued a claim to the owner, requesting the following: 1. A 1-week (5 workdays) time extension 2. An extra $23,600 (to cover the extra costs for excavating, hauling, and dis- posing of the contaminated soil, plus the GC\'s overhead for the extra week of duration) Do you think the contractor\'s claims are legitimate? Analyze both the contractor\'s claims (time and cost) separately. Explain your answers

Solution

1) First claim can be legitimate because there may be large uncertainities possible in any project execution. But this time extention should not be more because it will affect the final time estimate of the project and also disturb other activities of the project.

2) Second claim of contractor of cost increament is not legitimate because during the estimation of any project there is always 3% - 5% of the cost of project \'contigency\' taken in to account, which include the cost of all the unforseen circumstances that will incurred during project execution.
