1. Unforeseen/Existing Conditions
2. Plan/Specification Errors and Omissions
3. Owner Directed Changes
4. Force Majeure
5. Regulatory Changes
1. Unforeseen/Existing Conditions -- These are conditions in the field that do not match the conditions as detailed on the plans. Not performing selective demolition during the design phase on wall finishes, ceiling, roofs, etc. to allow observation of underlying conditions (when permitted) is not an excuse for an unforeseen/existing condition.
2. Plans/Specifications Errors and Omissions -- Errors are defined as mistakes or inaccuracies in the plans and specifications. Examples include applying the wrong standard, failure to meet design standards, incorrect calculation, or specifying the wrong size item. Omissions are defined as failure to incorporate all needed items. Examples include omitting an element of a standard, omitting an element of a useable unit or oversight of field conditions. E&O also includes items improperly drawn or improperly coordinated by the design team. Design errors are mistakes made by the designer that when corrected do
not add greater value to the project.
3. Owner Directed Scope Change (additions/deletions) -- An owner directed scope change can occur due to unexpected needs, time schedule change, change of business, purpose of project, acquisition of more capital, or the depletion of expected available funds.
4. Force Majeure --Time delays due to forces beyond the control of the contractor (i.e., accident, fire, flood, lightening strikes, and severe weather).
5. Regulatory Changes --Code change after bid award.
In my next posts I will discuss each of these in further detail.
