Cumulative Impact Claims


Understand the methodologies used to identify and analyze the impacts of a cumulative impact claim.

Change orders on a construction project are commonplace and should be expected by all parties. The costs, both direct and indirect, associated with an individual change order can be readily defined, and thus (to the extent allowed by the contract agreement), easily captured by a contract modification. But what happens there are an excessive number of change orders on a project? What is the effect of an excessive number of change orders on 'unchanged' work? This topic will help all project stakeholders to understand how the number of change orders issued on a project affects the 'unchanged' work and how to quantify that impact. The material will define what a cumulative impact claim is and identify the key components as well as explore various methodologies used to identify and analyze the impacts of a cumulative impact claim.
